JEV BENAR-BENAR GILA. Kami memberinya 400 perusahaan dan satu profil kandidat. Dalam 12 detik, ia memprediksi pekerjaan yang paling mungkin didapat kandidat, memberi skor keyakinan, dan mendeteksi ketidakcocokan pekerjaan dengan kandidat. Dengan biaya hanya 0,0005 dolar, ia juga bisa menilai perusahaan, menganalisis pengalaman Anda, mencocokkan posisi yang tepat, dan menemukan peluang yang paling mungkin berdasarkan profil Anda.

JEV is INSANE. We gave it 700 high-intent leads and personalised outreach messages. In 40 seconds, it predicted how each message would perform, assigned a confidence score and detected lead-message mismatches. All for just $0.09. JEV can also score leads, analyse buying signals, match each prospect with the best message and identify the campaigns most likely to perform based on data. Coming soon to @GojiberryAI+ MCP.

Built a tax document classifier with Jev. We ingest thousands of tax documents using an LLM pipeline I built last tax season. I read multiple articles as late as April this year claiming AI fails at tax document classification. Wasn't the case back then, and it's proved wrong again now. Jev classifies 100% of our tax document corpus at $0.001 per page. 34x cheaper and 6x faster than the LLM setup. Open sourcing it: https://t.co/gInVHudFRn

Okay so Jev can actually do computer use really well Without any screenshots, or LLMs and no Pixels leave my mac I dont even read the Dom elements A local CoreML model segments every button and UI element on screen. On-device OCR reads the labels. That text is all Jev gets. It returns a probability across those elements and tells me the best one to click. Then it clicks, re-runs detection, and decides again. In a loop until the goal is done. ~90ms per decision. Faster than any LLM computer use I've tried. Blazing fast computer use, without any latency @typesafeai is building something really interesting

Jev will be super helpful for agents to make split second decisions in workflows, data classification, judgment calls, and hundreds of other use-cases in the enterprise. Here's a quick demo with Box and Jev to make that real. The demo pulls an incident report from Box, asks whether it's customer-facing and how severe it is, moves the file into escalate, monitor, or review folders, and sets a metadata template instance with the result. This all happens nearly instantly and at almost no cost. You can imagine this in insurance claims, contract management, loan processing, security reviews, customer log analysis, and so on. Definitely a great new class of AI use-case.

卧槽，JEV 的出现很可能就是自动智能交易的起点。 昨天JEV在AI 圈刷屏，今天 Monad 工程师就用JEV做了一个自动交易机器人。 实时读取 MON/USDC 价格，JEV 不负责写分析报告，也不跟你解释一堆逻辑，它只做最核心的事，判断 Buy 还是 Sell，再给出置信度，然后直接把交易发到 Kuru 的链上订单簿执行。 这一下我突然明白 JEV 为什么要做成一个不会说话的模型了。 交易根本不需要 AI 每 300ms 给你写一篇小作文，它需要的是： 行情进来→判断→下单→新行情→重新判断，而且这一整套循环必须足够快、足够便宜。 而 Monad 现在刚好每 300ms 出一个区块，Kuru 又是链上订单簿。高性能链负责执行，JEV 负责决策，两个东西拼起来，已经有点AI 原生交易系统的味道了。 未来的交易 Agent，不一定需要一个会写研报的超级大模型，它更需要一个能在极低延迟下连续做几百万次判断的大脑。 昨天我 提交的WL今天也通过了，接下来我先尝尝咸淡，看看到底怎么个事。

Jev + Kimi K3 for fraud detection! TLDR: Jev classified 100 emails in 1.42 seconds, then I routed the uncertain cases to Kimi K3. The full pipeline got 96/100 correct for only ~$0.07. Video is not sped up, check out the live run! Here was my process: I gave Jev 100 emails to classify (a mix of 50 legit & 50 fraudelent emails). It classified all of them in 1.42 seconds. An underrated feature about Jev is it will give you the confidence score for a classification, so I routed any prediction under 95% confidence to Kimi K3 to be fully sure. 31 emails fell below that threshold. After routing those to Kimi K3, the combined pipeline reached 96% accuracy. The full run took 16 seconds & ~$0.07 in inference costs: - $0.068 from Kimi K3 on @togethercompute - $0.003 (1/3 of a cent) from Jev on @typesafeai. I think this is a really interesting pattern: use a fast specialized model like Jev for the narrow task, then route the uncertain cases to a larger LLM. I feel like this kind of approach could be a game changer for use cases like fraud or anything realtime. You can use the speed & low cost of Jev while having a larger LLM as a fallback to ensure high accuracy.

Jev V13 vs Fable 5.1: • fable outplayed it. by move 29 it was +16 in material and even promoted a second queen • but it kept burning 6-15 seconds per move on analysis. jev answered in ~2.6s • so fable didn't have enough time and lost Jev V13 vs Astra: • astra didn't bother winning on material. it mated jev in 18 moves.

I used Jev to classify 1,018 AI research papers. The result: $0.08 total cost and 256ms median end-to-end latency per paper. The pipeline was: 1. Summarize each paper with DeepSeek V4 Flash 2. Send the title + summary + 24 possible topics to Jev 3. Use Jev to classify each paper 4. Visualize everything on https://t.co/hs63SlHxjw The summaries cost $3.99 on @togethercompute. The classifications cost $0.08 on @typesafeai. So for just over $4 of inference, I ended up with a pretty useful way to explore the top AI research papers from the past year. I think this is where things are heading: different models for different parts of the workflow, instead of using one model for everything. I’m running evals on the Jev classifications before replacing the current ones, but the site is already live: https://t.co/hs63SlHxjw

Wow, @typesafeai Jev is a game changer for voice-driven UI. Responsiveness really matters for an experience to 'feel' right, and this certainly does the job! Latency here is not optimal given I'm in London and calling out to us-west. But still, super snappy. In this video, Jamcat is using Pipecat to orchestrate a real-time handover between a command agent (Jev) that drives the UI, and voice agent (PhoneLLM) for handling generations and (not in the video) discussing ideas and session setup with the user.

很多人没看懂爆火的JEV是什么？ 所以我做了一个 50 秒的演示视频，带大家把海外刷屏的 JEV 以及它背后的底层架构看透👇（见下方视频） JEV 是前 OpenAI、参与 ChatGPT / RLHF 的 @CompleteSkeptic（Diogo Almeida）创办 @typesafeai 后的第一款模型 他在 OpenAI 时发现了一个致命矛盾： 通过人类偏好微调（RLHF）训练出来的自回归大模型，存在严重的模式崩溃（Mode-dropping）、过度自信与幻觉，且串行逐字生成的延迟极大，根本无法胜任严肃的机器自动化生产 为此，他们花了两年研发了专为自动化设计的 System 1 基础模型 JEV，核心架构创新非常激进： • 单次并行计算（One Parallel Pass）： 如同当年 Transformer 取代 RNN 一样，JEV 彻底抛弃了逐 Token 串行吐字的自回归机制，采用全新的模型架构与采样器，一次性并行击发所有预设选项 • 强化学习校准决策（RL for Calibrated Decisions）： 引入全新的训练算法，输出媒介不再是自然语言文本，而是直接输出经过置信度校准的概率分布 • 代码级可靠（TypeSafe）： 彻底根除幻觉，输出自一致、确定性高，可作为强类型对象直接被程序调用 • 100 倍提速与极端降本： 延迟降至 0.1 秒以内（快到能直接插入 60 FPS 游戏循环）；输入每 10 亿 Token 仅 42 美元，输出 Token 彻底免费 视频里我把传统自回归的 8.5 秒延迟瓶颈、JEV 的并行矩阵运算，以及实时控制小游戏实测，全拉通做了可视化, demo参考 @MatijaSosic 聊天需要慢推理，自动化需要快直觉，Building Prod, not God 确实不是一句空话🫡

so I gave jev full control of the falcon-9 class rocket full launch to landing no autopilot, no scripted trajectories, no safety veto in the code every decision was made by jev ( you can see decisions at the bottom of the video) and yeah it was able to land the booster and all this with just 245 calls and and $0.04 in API calls for sim I used mujoco and the configurations were 42m booster, 425 tonnes, 9 engines, real atmosphere, mach dependent drag, wind and propellent depletion the vehicle was going ubstable every .8 secs, and jev's decesion making takes place at ~1Hz and output in ~0.4 sec so I gave jev these controls > launch or hold >engine count for every burn( it chose 5 for landing by itself !) > when to light that burn >ascent cutoff, coast, entry, legs, touchdown so after giving all these controls to jev the experiments begun and after 12 runs and tweaking multiple things it managed to land by itself I will write a full article about it and what I did with experiments and whet I tweaks I made but for some final thoughts people are saying it's just a classifier yes, but it's a very good and effective classifier, and its speed and decision making, open up a whole new work for real life tasks and implementationa I will also open source the whole repo for this after cleaning up the clutter in my code so this is the short demo I hope you like it

Takie modele jak JEV (System-1) zmienią moim zdaniem bardzo dużo. Obecne modele LLM symulują System-2. Dla mnie implementacja jev to jedna z najświeższych koncepcji ostatnich miesięcy. Niby nic szczególnego (dynamiczny klasyfikator) a dziwi, że tak długo trzeba było czekać na taki model. Uniwersalny klasyfikator, inteligentny "if". W swoich poprzednich wpisach objaśniłem jak to działa. Mam dostęp do API @typesafeai @CompleteSkeptic więc zrobiłem self-play w moim pac-man. To "zabawkowy" przykład ponieważ schemat zapytań jest stały ale ... w wielu systemach np. agentowych schemat jak i stan zmienia się w czasie (w pac-man tylko stan się zmienia). W bardziej zaawansowanych, złożonych systemach struktura stanu, jak i wartości atrybutów stanu są zmienne w czasie, kontrakt klasyfikatora (liczba klas jak i ich semantyka) również. I tutaj mamy system-1 jev - podejmuje decyzje. Oczywiście można to zrobić na LLM ale będzie wolniejsze, droższe, sekwencyjne (wzajemnie zależne - w kontekście widać odpowiedzi). Można wykorzystać dyfuzyję z blokiem odpowiedzi wypełnionym nie na szum a na szablon odpowiedzi (będzie szybko) - generować tylko proby. Możliwości są chodzi natomiast o samą koncepcję Systemu-1. Widzę szerokie zastosowanie - inteligentne aplikacje, systemy agentowe, w klientach do kodowania -> obniżenie kosztów, zwiększenie szybkości działania, jakości rozwiązania itd.

Jev is actually insane.

The bottleneck is not Intelligence latency anymore. It's the first System 1 LLM. Crazy times.

Jev made our Slack agent 2x faster ⚡️ Our agent can be quite slow because it needs to read skills and figure out which tools to call. We used @typesafeai's new model to speed this up by first passing it the prompt and classifying the best skill, tool and params to use before handing it to the agent

Played around with @typesafeai Jev today, mostly to understand what it does for tool calling. Instead of an LLM deciding what to do, I substituted that part with Jev. My learning is that we will be able to make the agent act before the user finishes the sentence. So far, we've used different LLM combinations (non-thinking + thinking ) plus state machine setups to get the right experience for the end user. TLDR is to understand more about how voice agents can run decisions on partials instead of waiting for the end of the turn, with lower costs.

Jev vs GLM 5.3 at chess! Results: ◾ GLM 5.3 won by checkmate in 29 moves ◾ Jev: ~0.3s and <$0.0001 per move ◾ GLM 5.3: ~5.8s and ~$0.008 per move ◾ The whole game cost 24 cents My main takeaway is that it's often useful to use each one to their strengths: ◾ Fast, well-defined classification → specialized models like Jev ◾ Classifications that need reasoning or lookahead → LLMs like GLM 5.3 ◾ Real classification pipelines → hybrid. Jev handles the easy calls, an open model handles the hard ones. The future is multi-model!

arkadaşlar jev'e early access aldım ve test etmeye başladım ve gerçekten çok impressed olduğumu söylemem lazım sadece şu kaydettiğim demoyu bi izleyin lütfen. kesinlikle hızlandırılmış bir video değil. 4 tane jev karşılıklı 101 oynuyor ve oyunun hızına bir bakın. beni takip edenler bilir. yıllardır her yeni model çıktığında bizim meşhur 101 okey oyununu oynatırım. benim kişisel benchmarklarımdan biridir ai modellere 101 oynatmak. kimi cahiller ehi ehi ehi adam modele 101 oynatıyor dese de asıl benchmark budur. bizim eve bundan başka benchmark girmez. çünkü 101 göründüğünden çok daha zor bi testtir modelin önce oyunun kendine özgü kurallarını anlaması, sonra oyun boyunca bunlara eksiksiz uyması gerekiyor. ama bu da yetmiyor. elindeki taşları, masa'nın durumunu yani son state'ini ve rakiplerin hamlelerini değerlendirip doğru kararı zamanında vermesi gerekiyor. yani masanın anlık state'ini de her modelin bilmesi ve hızlı karar alması gerekiyor özellikle bu son kısım bugüne kadar modellerin en çok zorlandığı yerdi openai, anthropic vs. modelleri iyi karar verebilse bile bazen 30 saniye veya daha fazla düşünüyor. gerçek zamanlı oyunda iyi karar vermenin tek başına hiç bir anlamı yok çünkü doğru kararı verdin ama sıranı kaçırdın ise pek bi işe yaramıyor. dolayısıyla hız + doğru karar en önemli metrik burada. jev duyurulur duyurulmaz early access'e başvurmamın sebebi de buydu. direkt aklıma 101 benchmarkım geldi jev aslında konsept olarak çok da yabancı bi şey değil. kabaca generalized zero-shot classifier diyebiliriz. uzun uzun metin üretmek yerine kendisine verilen state üzerinde tanımlı seçenekler arasında karar veriyor ama güzel olan bunu ne kadar hızlı yaptığı benim 3-4 yıldır farklı modellerle denediğim ama bir türlü tam verim alamadığım ai'ın 101 oynaması problemini jev çözmüş gibi görünüyor kararları milisaniyeler içinde veriyor ve oyun boyunca oldukça isabetli oynuyor bence asıl önemli tarafı da 101 değil zaten 101 bunun küçük bir demosu computer use, browser use, hız gerektiren oyunlar vs gibi alanlarda yani modelin sürekli ne yapmam lazım diye düşündüğü her senaryoda jev hızır gibi yetişiyor. milyonlarca küçük karar için çok çok ideal gözüküyor milyonlarca mini karar için 30 saniye düşünen dev bir generative model gerçekten işlevsiz. onun yerine 100 milisaniyede yeterince iyi karar veren bir model daha mantıklı jev'in yaptığı da bu bence müthiş bir ihtiyacı karşılıyor ve karşılayacak. hatırlayın 4g gibi hızlı internet altyapıları yokken tiktok vs gibi realtime streamingler mümkün değildi. tiktok'un ortaya çıkabilmesi için 4g ya da hızlı internet gerekliydi. şimdi jev = 4g. hız konusunu çözüyor. dolayısıyla jev'in tiktoku yani jev sayesinde ne gibi yenilikler ortaya çıkacak acaba görürüz önümüzdeki dönem. eğer anlık olarak milyonlarca mini karar alınması gereken bir konseptiniz varsa çok ideal bir şey jev. openai ve anthropic gibi şirketlerin de benzer şekilde generation ile decision'ı zamanla birbirinden daha fazla ayıracağını düşünüyorum

这两天关于 Jev 这个模型的热度非常之高，甚至可以说是近半年我重点关注了英推以来，看到的原创内容密度最高的一次。 正好我过去一年一直在跑一个小项目，其中有一个环节就是要对每天出版的《人民日报》上的新闻做一个分类，判断每一篇文章中是否包含有湖北相关的元素。 一年跑下来，积累了接近 2 万 4 千条数据，其中判定包含的有 1800 条左右。在这些数据的基础上，我随机筛选了一个测试数据集，其中包含了 500 条判定包含的内容，以及 500 条判定不包含的内容。 之前我使用的模型一直是 Gemini 的 Flash Lite 系列，也算是经过测试后成本和速度双重考虑下的最佳选择。 今天 OpenRouter 上线了这个 Jev 之后，我用同样的提示词做了一个小 Demo 做了一下对比测试，下面这个视频就是同时并发 16 个进程的实录效果。 不得不说，测试出来的结果超出预期很让人惊喜啊。 首先，速度是真快！相对于 Gemini Flash Lite 单篇文章 3 秒的平均耗时，Jev 把单篇耗时缩减到了 0.35 秒。这个接近 10 倍的速度提升，真的是实现了质的飞跃，带了很多新场景的想象空间。 其次，质量也真不错！和 Gemini Flash Lite 的分类结果相比对，Jev 大概在 15% 左右的内容上出现了判断不一致的情况。 但经过我的手动审核，大部分都是因为人名而导致判断差异。例如某位此前在湖北省任职过的官员姓名出现在了新闻中时，Flash Lite 因为知识库比较大，会将其判断为包含，而 Jev 在这块上面会弱一点，因此判定为了不包含。在我的实际应用场景中，这种判断差异完全可以接受。 最后，价格也是真便宜啊！看了一下 OpenRouter 的账单，前前后后大概跑了 5 千条数据，30M Token，总共开销也就 1 美元！这个性价比，还要什么自行车！ 总之，我个人觉得 Jev 代表的分类器大模型的确是一个非常有前景的发展方向，甚至可以说是在分类场景下实现了速度/质量/价格的不可能三角，有类似需求的朋友真的可以好好考虑一下。 就分享到这了，我得连夜用它去优化生产项目了。

If you're in marketing, this kind of crazy fast data crunching is hands down the best thing out there. Doing this through Opus 5 would run around 2 to 4.5 million tokens, set you back $15 to $50, and take anywhere from 10 minutes to an hour.

Introducing the Papers with Code MCP server! To celebrate its release, I've asked Claude Code to research the architecture of Jev by @typesafeai using the `search_papers` tool. Here's what it came up with: "If Jev is architecturally anything public, it's a large schema-conditioned bidirectional encoder with parallel label-query heads (GLiNER/ML-Decoder shape) trained with a proper-scoring-rule RL objective (RLCR shape), scaled far past the ~150M-param range those papers operate in — "neither small nor an LLM" fits that. The 40–200× speedup is consistent with removing autoregression, not with any exotic mechanism."

I did my master's thesis on classification models so it's fun to see a modernized version of a very useful alg Typesafe are correct in that LLMs are just one approach to intelligence, and I think as time goes forward we’re going to see a hybrid of dif models splitting up and allocating correct parts of a problem, using less tokens overall and leaning on LLMs for less of the answer. I’m bullish on what I call 'combination input' approaches: breaking a statement down into a series of classifications and routing each to the right type of model rather than just brute forcing the whole thing with an LLM cc / @CompleteSkeptic @typesafeai Link below, please enjoy

Acabo de terminar la implementación de @typesafeai + Chromium Headless para que mis agentes puedan navegar por internet a una buena velocidad! En este ejemplo le pido al agente que entre a la página del término "Café" en Wikipedia y navegue por los hipervínculos hasta terminar en la página "Inteligencia artificial" Logra completar la prueba en 20 segundos. Creo que pocos humanos podrían hacerlo en ese tiempo.

Had jev, claude haiku 4.5, and gemini 3.5 flash-lite play tetris. Same 200 pieces, same legal moves, real time. Jev: 9200 pts, 75 lines, 300ms/move, 0 errors Claude: 8900 pts, 72 lines, 1.52s/move, 0 errors, $0.48 Gemini: 9000 pts, 75 lines, 1.13s/move, 0 errors, $0.02 Jev wins on score and is doing it 4-5x faster per move than either LLM, for basically free. That gap isn't the model being smarter, it is the model doing less work per decision

JEV CAN DRIVE! 🤯 I hooked up Jev to the raw controls of a driving simulator, this video shows him driving in realtime. Realtime is the kicker here. Asking a model what to do every 50ms then rendering that into a "realtime" video is one thing, but in this simulation I wanted to give Jev the challenge of actually controlling a moving vehicle in a simulation that will never pause while he thinks.

I got access to Jev and immediately plugged it into Claude Code to see if it actually FIXES the biggest pain of agent workflows: context compaction > result: pretty wild Quick context for those who missed it: Every Claude Code session has a context window that fills up fast with tool calls (file reads, grep outputs, logs, etc). When it fills up, the agent runs "compaction" - asks a separate LLM to summarize the chat. this is slow, expensive, and the LLM often drops important context or bloats the summary with garbage: fast-jev-compaction uses Jev instead Link: https://t.co/WD7kpBfDwL Why this works so well: Instead of generating a text summary, Jev scores every tool call in your chat with "how important is this?" probability. > above threshold → keeps it > below → drops it or replaces with a stub > in summary: no text generation, no bloat, no dropped critical context What you actually get: 1/ way faster: Jev outputs probabilities in parallel, not sequential tokens. 2/ way cheaper: 1M tokens of context = ~$0.04 to compact. 3/ deterministic: no "creative" summary that removes half your codebase context. btw, TypeSafe gives $5 free credits at enough for weeks of testing. Link: https://t.co/NzGPArgLvc Honest caveats: Jev only sees the tool CALLS, not their outputs, hard to say if compaction quality is objectively better than default. Jev's context window is small (32K), so 150K+ chats need to be chunked. This isn't a full replacement - it's a smart pre-filter but as a proof of concept. This is exactly the kind of surgical fix that makes agent workflows viable at scale. Now thinking about what else in my stack could get 100x faster with Jev as the decision layer.

TYPESAFE RELEASED A MODEL THAT DOESN'T GENERATE TEXT, AND IT BREAKS THE COST FLOOR OF THE AGENT LOOP jev is what they call a system one model. you send it a state and a set of questions, it returns typed answers with probabilities. no tokens, no sampling, no sequential decoding. route → decide → guard → run tool → observe → done? they report 20-200x faster inference and 40-400x lower cost than comparable llms on classification tasks. every question in a request is evaluated in parallel, so adding questions barely moves latency. in a two-turn loop that means eight decisions. the two that need a plan still go to a chat model. the other six - pick a model, screen a tool call, check if the task is done - cost 0.06s combined. the takeaway is simple: stop paying generation prices for choices. most of what an agent decides is a pick, a score or a yes/no.

Jev is already on OpenRouter!! It's only been out a day and TypeSafe still has a waitlist. OpenRouter has it though, and that's how we've been running it. The pricing is insane. $0.042 per million tokens in, and output is free. How to use it: - Sign up on OpenRouter and add some credits - Make an API key - Call the decisions endpoint: /api/alpha/decisions - Set the model to ~typesafe/jev-latest - Send it a "state" (what's going on) and "questions" (what you want decided, plus the options) ChatGPT and Claude write you an answer word by word. Jev doesn't write at all. You give it the options and it sends back a probability for each one, plus how confident it is. What we got: - "My card was charged twice" went to billing, 100%, in about a second - We hooked it up to Tetris and it picked every move in about half a second - A whole game cost less than half a cent A lot of fun stuff can happen here.

Jev is insane for ad research. I built a tool that scores every shot of any video ad on meta in 1.5 seconds. It runs on Maxfusion + @typesafeai I pushed 450+ ads through it in less than 3 minutes. It pulls any advertisers live video ads from Research Lab on Maxfusion. Maxfusion watches the ads and gives a forensic breakdown. Jev then judges each shot and rates the whole ad. It made 50 judgments in 1.52 seconds for $0.00028 and scored this Duolingo ad at 88. Jev is the fastest decision maker I have ever worked with.

Ran a dumb experiment last night: used Jev by @typesafeai (a decision/classifier model, not a text-gen model) to write C++. At every step I gave it the finite set of grammatically valid next tokens and let it just... pick one. No free-form generation, no hallucinated syntax, purely "choose from this legal set." It's not built for this, that's what made it fun. Got a working piece of C++ out of a model that fundamentally does not generate text. Not claiming this is how you should write code, and it's slower and dumber than just using an actual code model. But it's a neat proof that a classifier constrained tightly enough can stumble into looking like a generator. Novelty over utility here, but it's the kind of dumb experiment that tells you more about a model's actual guardrails than the official demos do.

Had some fun taking Jev from @typesafeai for a spin, switching seamlessly between manual and AI-driven gameplay. It’s clocking 2–3 calls/sec at 60 FPS, with ~150ms avg latency. The most interesting part wasn’t the speed, though. It was distilling the game into the variables, actions, and decision criteria the AI needs to play well: Does it risk going for the powerup, or protect the ball? When is the reward worth the risk? Fun times ahead!

Got early access to @typesafeai Jev and spent a few hours building on it. The problem I keep hitting: agent traces tell you which tool ran, how long it took, what it returned but never whether the agent is actually getting anywhere. An agent editing, testing and reverting the same file six times looks perfectly healthy in the logs. So I made JevScope. It watches an AI agent work and asks Jev what each step actually means is this aligned with the task, is it progress, is it repeating itself, is it stuck. Every step, plotted over time. Here's a coding agent getting stuck on a race condition. Watch the yellow line. No log line says "I'm stuck." The curve does. Detailed demo, code and writeup coming soon.

Another brilliant launch for developers: and its 20-200x faster than LLMs because it skips token-by-token generation entirely. TypeSafe AI just launched Jev, > 20-200x faster >40-400x cheaper (w/ output tokens free) > Frontier composable intelligence optimized for decisions So Jev is an AI model built to make software decisions instead of writing text for people. A normal LLM answers by generating tokens sequentially, so software often has to request structured output, parse it, validate it, and decide what happens next. Jev removes that translation layer: give it some data and a predefined question, and it returns a typed choice or score with probabilities and confidence. For example, a support app can ask whether a ticket is urgent, whether it violates policy, and which queue should receive it, then act on those answers directly. In code, Jev behaves like a smart if-statement: ordinary software controls the workflow while the model handles fuzzy judgments that rigid rules struggle with. Jev evaluates multiple structured questions in parallel rather than writing an answer token by token. TypeSafe reports 70-500ms responses and 40-200x faster performance than comparable LLMs

man who co-invented ChatGPT just shipped a model that does in 0.114 sec what GPT Astra does in 8.5. i wired Jev into the routing layer of a build i was running on Astra: same task finished 37 MIN SOONER, zero malformed responses to retry. you hand it a situation and a list of typed questions. it answers all of them at once, in parallel, with a confidence number attached to each. no chain of thought, no tokens streaming out one by one. you stop parsing a JSON blob back into your code and praying it validates, because the model physically cannot answer outside the options you defined. the numbers TypeSafe publishes for it: > $0.042 per million input tokens, and output tokens are free > same accuracy as Sonnet 5 on their eval, 67.8% for both, at 294x less cost and 195x the speed > 0.114 seconds against 8.566 for GPT-5.6 Terra on the same demo > their Doom demo has it making around 10 decisions per second $40M seed led by DCVC, and the name is a nod to Jevons, the economist who showed that cheaper coal meant burning more of it, not less. this runs underneath the agent, on the calls that happen ten times a second and never get read by a person. waitlist for the API, but the browser playground is open now. links below.

Built an SO-101 pick and place simulation using GPT-6 Astra and @typesafeai Jev. Astra reads overhead and wrist camera images and produces structured observations and Jev returns typed decisions with probability scores. A separate local controller carries out the movements and checks that the arm stays within its limits and is ready for each step. The models never directly control the motors. A fixed pick and place sequence probably doesnt need this much decision making. I m using it as a testbed for situations where observations are uncertain and the system needs to decide whether to act wait or stop.

Imagine a Magic 8-Ball that actually works: a typed answer, with odds and a confidence score. This means they can: • Model routing: send each request to the right mode • LLM output checks: flag weak answers for review before users see them • Support workflows: sort tickets and decide which to automate or escalate And just realized TypeSafe reports ~150ms latency, ~100x lower cost & faster responses than LLMs. Early API access waitlist is open below.

Finally I got access to @typesafeai (thank you guys!) Jev + emulator lookahead cleared Super Mario Bros. 1-1 only 0.04$. In this setup, Jev sees no pixels: I parsed RAM into structured state, simulated controller macros, filtered predicted deaths, and let Jev choose. Recorded the run; resumed from the same state after an API outage. The tradeoff: RAM gives precise, auditable observations, but my adapter is game-specific. Bypassing vision makes this experiment easier; it doesn’t solve perception for general game agents. The potential is Jev as a tactical decision layer over structured observations and predicted outcomes. Caveat: 1-1 is easy for RAM + search. Next: Jev vs a cheap heuristic on identical simulations. Does the model actually earn its place?
