🛠️ New Tools

• ViBT (Vision Bridge Transformer) accelerates high-quality image and video editing via Brownian Bridge trajectories, delivering up to 4× faster inference. Builders get pro-grade results with lower latency and cost.
• DeepCode ships a multi-agent framework that turns dense research papers into working codebases. It orchestrates context and blueprints, shrinking time-to-implementation for cutting-edge ideas.
• Microsoft + LangChain Community launched an open-source Azure AI samples repo with serverless RAG workflows across languages, lowering friction for production-grade retrieval and orchestration.
• MiniGuard‑v0.1 blends datasets and Qwen/Hermes backbones to reduce unnecessary refusals while maintaining safety. Teams get more helpful responses without sacrificing guardrails.
• Prime MCP enables on-demand cloud GPUs directly inside Claude and Cursor workflows. Developers can run heavy jobs without context switching or full infra setup.
• Chutes introduces “Login with Chutes,” letting apps pass inference costs directly to end users. This simplifies billing and enables sustainable pricing for AI-heavy features.

🤖 LLM Updates

• OpenAI GPT‑5.2 rolls out with “Extended Thinking,” boosting reasoning and complex coding. Early praise notes better step-by-step planning, though rankings remain volatile across tasks and domains.
• Benchmark whiplash continues: GPT‑5.2 variants trail Claude Sonnet 4.5 on AA‑Omniscience, while Gemini 3 leads elsewhere and Meta reportedly matches OpenAI on key scores, underscoring test sensitivity.
• Mistral 3 Large reportedly adopts a DeepSeek V3‑style MoE with fewer, larger experts. Expect improved efficiency and throughput on complex queries at lower serving costs.
• LLaDA 2.0 introduces a 100B discrete diffusion LLM with optional MoE and ~2× faster inference. Immediate SGLang support eases experimentation and deployment.
• NanoGPT + Muon set a training speed record, highlighting optimizer and kernel gains that cut compute bills and shorten iteration cycles for researchers and startups.
• Access broadens as GPT‑5.2‑xhigh lands on WeirdML, while Korea’s “National AI” models debut on Hugging Face, expanding options for benchmarking and fine-tuning.

📑 Research & Papers

• DeepMind trains robots using video-based world models that generalize across tasks without extra hardware trials, promising safer scaling and faster deployment of embodied agents.
