Pika released Pika H3 Flex , an open-weight video+audio model post-trained on MiniMax H3. Generates 15-second clips with soundtrack in as little as 7 seconds using a custom 6-step sampling schedule.
IFM delivered K2 Horizon 360: 8 artifact categories and 30+ repos covering every LLM training stage, see artifact directory . 380 checkpoints across six models from pre-training through RL, letting you trace when capabilities emerged.
Fish Audio released Drama 3 , a 35B MoE TTS model with 3B active parameters, open weights on Hugging Face. Ranks #1 open-weights on both Artificial Analysis Speech Arenas and #1 overall on Pronunciation Robustness at 94.6%.
Mistral released the open weights for its 1-trillion parameter Mistral Large 4 model, now leading open-weight coding benchmarks with multimodal input and cyberdefense tuning.
An independent 4B fine-tune of Qwen3.5 turns plain text prompts into self-contained Three.js scenes, with weights, dataset, and GGUFs public.
A classic Wide-ResNet-50-2 backbone retrained with the RACM recipe is quietly pulling 850K+ monthly downloads on Hugging Face for image classification work.
AtomicChat released GGUF builds of NVIDIA's Nemotron 3.5 Transcribe 30B-A4B speech model. Seven decoder sizes from 13.57 GB to 35 GB cover 16 GB GPUs through workstations. Accuracy stays within ±0.18 WER points of BF16 on English, German, French, Spanish.
Meta opens its Muse model family and computer vision stack to five US universities tackling heart failure, cancer, dementia, and frontier math.
Google open-sourced EGM, a plugin that uses deep-context agents to draft software specs and zero-context subagents to tear them apart before any code is written.
Zed 1.26 ships expandable variable inspection in debugger hovers, built-in Pyrefly for Python, and DWARF debugging for WebAssembly sources in the JS debugger.
NVIDIA's open-weight 30B mixture-of-experts speech model handles transcription, diarization, translation and audio Q&A in 40 languages from one checkpoint.
NVIDIA's new 30B mixture-of-experts transcription model matches top open-weight accuracy at 2.8% WER while using 6x fewer active parameters than rivals.
Baidu's 3B open-source vision-language model parses hundred-page documents in a single request using a sparse attention trick that keeps memory flat.
CopilotKit released an MIT-licensed template for proactive AI agents that handle work in the background, request approvals, and run across web, mobile, Slack and Teams.
AtomicChat released uncensored GGUF builds of DeepSeek-V4.1-Flash-1017, a 763B parameter MoE model. JailbreakBench refusals drop from 85-89% to 0% across all three quantization rungs. MMLU stays within ~1 point of the stock quant, KL divergence around 0.02.
NVIDIA released Auto Ontology, an open-source Python framework that builds semantic graph layers over enterprise data so agents generate SQL deterministically with provenance.
InclusionAI's updated 560B MoE reasoning model jumps three points on the Intelligence Index while keeping the same price tag and MIT license.
Liquid AI's LFM3 family packs text, vision, audio, omni, and decision models into one 2B backbone built for on-device fine-tuning.
Dossier is an open-source, self-hosted job hunting app that pairs your profile with a local or hosted LLM to draft tailored resumes, cover letters, and track every application.
An open-source workspace brings AI agents into PCB and mechanical CAD design, with a forked KiCad, deterministic 3D viewers, and bring-your-own-LLM support.
