Data & evaluation

JEV is INSANE. We gave it 400 companies and one candidate profile. In 12 seconds, it predicted which jobs the candidate had the highest chance of getting, assigned a confidence score and detected job-candidate mismatches. All for just $0.0005 It can also score companies, analyse your experience, match you with the right roles and identify the opportunities you’re most likely to get based on your profile. Coming soon to @textbackdoor Comment “JEV” for early access.

jev is insane 🤯 Here is Jev playing subway surfers at super human speed, and also playing 50 games at once. cost less than a cent to do this run. Jev does not replace llms like astra or fable, but opens up an entirely new world of capabilities. https://t.co/T9QrLKmUcG

whoa this actually worked! Jev lets me control my browser in real time with my voice now > i talk > transcript sent to Jev > jev returns probabilities in ~300ms > browser clicks costs: $0.0002 per decision i'm stunned how fast this is. when i asked it to "go back", it even finished the request before i finished my sentence 😂

instead of generating text, jev from @typesafeai generates structured output this makes it great for classification tasks like model routing, tool selection/search, and guardrails of many forms! it's also ridiculously fast and cheap compared to LLMs doing the same tasks https://t.co/59a8PxBuQ6

I got a rubik's cube to solve itself with @typesafeai 's Jev and it solves it like a person does, 94 moves, not the 22 move optimal solution. Jev isn't an LLM, it just answers one question in ~250ms with a probability. so I put the beginner method in code (the one you'd learn on youtube: white cross, corners, middle layer, yellow layer) and at every step Jev just looks at the cube and picks which case it's in. code checks every pick. ~4 seconds of model time total. video is slowed down so you can read it!

Research

I rebuilt my job crawler with Jev. The task: start at a company's official homepage, find Careers, and identify jobs that match my profile. Before, with an LLM: ~5 minutes. After, with Jev: just over 20 seconds in my test. Every company organizes its website differently. Jev identifies the Careers entry point, chooses which links to follow, recognizes job pages, and scores each role against my profile. This is where Jev makes sense to me: automation that needs lots of small decisions, with faster responses and lower costs than calling an LLM at each step. Packaged it as a skill: jev-job-hunter. Demo below.

jav @typesafeai - jestem pod wrażeniem 🤩 Cool. Napisałem kolejne demo. Myślę, że teraz to widać potęgę modelu ... i o co chodzi i widać prawdziwą wartość biznesową. Akt I - X-ray: „jedno zapytanie, wszystkie pytania naraz" - dla przykładowej, krótkiej notatki prasowej to 67 osądów w ~1 s za $0.0002; dla dłuższego RAPORTU może być i 145 osądów w 1,5 s za $0.0005. Skoro nie ma tokenów wyjściowych, to dorzucenie kolejnego pytania kosztuje tylko tokeny samego pytania. Zobaczcie jak można dynamicznie klasyfikować i jednocześnie pytać o wiele wymiarów. Akt I odpowiada na pytanie „ile" osądów naraz i za ile. 🥳😍😍😍 Akt II - Firehose: „AI jako zależność w pętli czasu rzeczywistego" - podłączyłem się do publicznego strumienia SSE Wikimedia (stream_wikimedia_org). Filtruję: angielska Wikipedia, przestrzeń główna, człowiek (nie bot). Dla każdej pobieram prawdziwy diff przez REST compare, który zwraca strukturę zamiast HTML-a. Potem 8 pytań o tę edycję: wandalizm, spam promocyjny, atak na osobę, edycja testowa, usuwanie treści, twierdzenie bez źródła, Score „ile szkody" (0–3) i Choice „co zrobić". 71 edycji w 75 sekund, 1,0 decyzji/s, mediana 306 ms, $0,19 za godzinę oceniania całej Wikipedii. Rozkład: 49 zostaw / 20 do człowieka / 2 cofnij. Akt II to „gdzie", że to może siedzieć w pętli czasu rzeczywistego, w rdzeniu systemu. Akt III - autonomia. TypeSafe nie publikuje benchmarków „poziomu inteligencji". Publikuje prędkość i cenę, czyli dokładnie to, co i tak łatwo zweryfikować. Czy zatem model wie, kiedy ma rację zostaje do zmierzenia użytkownikowi. No to zmierzyłem. 300 zapytań do asystenta głosowego, 150 możliwych intencji, a jedna piąta z nich prosi o coś, czego asystent w ogóle nie obsługuje. Jeden przebieg. Przy progu 0.90 z dodatkowym pytaniem o zakres: - 62% ruchu obsługuje się samo, bez człowieka - 99% z tego jest poprawne -> konkretnie 2 błędne odpowiedzi na 186 - 100% zapytań spoza zakresu zatrzymanych - pozostałe 114 ląduje w kolejce do człowieka Wykres po prawej jest ważniejszy niż te liczby. Oś X jakie prawdopodobieństwo model zadeklarował. Oś Y jak często faktycznie miał rację. Przekątna to uczciwość. Gdy mówił 0.99 trafiał w 99%. Rzecz, o której się nie mówi: sama pewność NIE wyłapuje zapytań spoza zakresu. Choice jest relatywny zawsze musi kogoś wskazać, więc wysoka pewność znaczy „ta opcja wygrała z resztą", a nie „ta opcja jest dobra". Dane: CLINC150, publiczny zbiór. Całość: ~20 sekund i 4 centy. Akt III na „czy można na tym polegać" i jak to działa (pomiar jakości).

i used Jev to classify a youtubers last 100 videos based on how likely it is to sell me something... it analyzed & assigned a sales intent score to each video within 12 seconds & cost about $0.02 i haven't done a deep dive into how accurate the score is yet, but from a quick glance it looks like a super promising classifier model

I gave an evolution simulation to Jev, a small model from @typesafeai that answers typed questions with odds instead of writing text. Two species with opposite DNA. 14 generations. An ice age. 432 creatures. Jev decided who survived, who mated, and what killed each one. https://t.co/Law8fyfy6d

Every model wants the job. The fast one says, “I’ve got this.” The reasoning model asks for more context. The safety model says, “Absolutely not.” Jev steps in and sends each task where it belongs. Jev decisions cost $0.04 per 1M input tokens on Aria — with no markup. @CompleteSkeptic The right task. The right model. The right decision.

I increasingly think future software will combine code for control flow with small neural programs for "fuzzy" judgments. That's what I've been exploring with ProgramAsWeights, which answers the question of where those neural programs come from: they are "compiled" from English descriptions. For example, I combined 30 neural programs with a decision tree to build a course website helper that looks like a chatbot but runs locally. Each small program handles a question like "Which specialist answerer should this be routed to", and code controls the overall flow. You can try building with it here: https://t.co/Bwgcn362bc

Woke up with early access to @typesafeai and was super excited to try. Got a demo cooking before work this morning where typesafe drives an AI co-op partner in my @threejs action game. Can see the log on the right tracking the AI decision making in realtime. Typesafe is reading game state and choosing intent for the bot: When to engage, regroup, survive, or escape. Obviously a bit primitive right now but this is like ~1hr worth of work. I need to run to work, but holy shit super excited to build on this 😄 The total spend for about 10mins play testing this morning was about $0.02. Let's fucking go 😂
