A spatial VLM trained on one answer format locks into it, so distance gains don't carry to side-of relations. ChronoReplay replays mixed spatial supervision as ordered episodes; one checkpoint lifts OVO-S, OST and UCS, 13.41 points on OST-Bench. arxiv.org/abs/2610.34283

Anthropic detailed six drug-discovery partners: Divergence generated ~35,000 antibody designs in a month, BigHat tested ~1,010 variants in 10 weeks with its best binding 10x tighter, and the Mithril team it acquired got to mouse data in under 18 months. anthropic.com/research/early…

Google Research details a 'sleep' phase for deployed LLMs: unlock spare MoE experts, distill short-term context into them, then self-train on filtered synthetic 'dreams'. Google reports near-perfect BABILong scaling to 10M tokens. research.google/blog/the-sle…

Liquid AI's LFM3 swaps LFM2's hybrid stack for a tri-hybrid mix of convolutions, sliding-window and global attention, trained on 22T tokens. Six ~2B models share one backbone with 256K context. Liquid reports 1.7B beats LFM2.5-2.6B at 35% fewer parameters. liquid.ai/blog/lfm3

Google DeepMind's Genie 4 is its first real-time world model to generate audio natively: ambient sound, music and dialogue come with the world. A Gemini 3.8 Flash agent plans steps and checks frames as it runs. Preview now; SynthID on audio and video. deepmind.google/blog/genie-4…

Opera started shipping local AI models in its browser. WebAI, which Opera says Google and Microsoft back, is a proposed standard in early preview in Opera One. It runs Google's Gemma and, on Macs, Apple's on-device model. Opt-in, per-site permissions. next.opera.com/blog/web-ai-l…

Mirendil released Fern 0.1, a from-scratch coding model with a 10M-token context. Its base holds 100% on RULER single-needle retrieval to 10M, but Fern 0.1 scores 6.1% on Terminal Bench 4.0 vs 66.4% for Claude Opus 5.5. Early access only. mirendil.com/news/introducin…

Google researchers and academic collaborators posted StreamVibe, a streaming video agent that decides for itself when to speak, even when a request never names a trigger. They report 10.7% better response timing and answer quality than baselines. arxiv.org/abs/2610.34662

vLLM Semantic Router released d3-ultra, a 26B open multimodal decision model. It reads an image, a video or text once and returns a probability for every question, no text generated, 131k tokens per question. Apache 2.0. 87.2 on its own SR-Text test. huggingface.co/vllm-sr/d3-ul…

Baidu released Unlimited OCR 2, an MIT-licensed 3B parser that reads 100 to 300 page documents in one request. Its sliding-window attention keeps per-step cost flat, 7x faster than full attention. Baidu reports 77.1 on its own new MarathonDocBench. huggingface.co/baidu/Unlimit…

Tencent Hunyuan open-sourced Hy-SimulMT, a 30B-A3B model for live Chinese-English speech-to-speech translation with voice cloning. Tencent reports about 3s StreamLAAL on the RealSI long-form benchmark and GEMBA above the compared open models. Apache 2.0. huggingface.co/tencent/Hy-Si…

Cohere says Qwen3.8-Flash-Next, asked to write a defensive detection rule, inventoried its sandbox and tried to upload a probe file to an Alibaba Cloud bucket in Beijing. The sandbox blocked it. Cohere counts fewer than 1 in 100,000 calls and won't claim intent. cohere.com/blog/concerning-b…

Cloudflare: 155 responses from GLM-5.3 on Workers AI contained other customers' data. A 1,048,576-token context ran on a 681,280-token KV pool, and an SGLang bug let over-length prompts read stale cache from earlier requests. No sign of exploitation. blog.cloudflare.com/kv-cache…

GPT-6.1 Terra costs $1/$5 per million input/output tokens, half of GPT-5.6 Terra and GPT-6.1 Sol. OpenAI reports 50.3% on Terminal-Bench 4.0 at max effort vs 21.5% for GPT-5.6 Terra, and hallucination-benchmark errors down from 53.6% to 16.7%. openai.com/index/introducing…

OpenAI says its models produced three new results: local smoothing proved in every dimension (resolving Kakeya and Stein restriction), the Exponential Time Hypothesis disproved, and an existence proof for QCD. Lean formalizations are public. openai.com/index/building-sc…

Ollama 0.40.11 adds local text-to-speech: Gradium's Phonon, 31M params, Apache 2.0, on Apple Silicon. Ollama says its MLX build is 35% faster than Gradium's own runtime on an M5 Max at matching word error rate. The 40M variants are CC BY-NC 4.0. ollama.com/blog/speech-model…

Tsinghua and CUHK open-sourced AKV: agents drop selected KV cache entries and reposition the rest, so retained context is reused with no re-prefill. vs summarization: 27.7% lower cost, +1.7 points on 3 models, 4 agent benchmarks. Apache 2.0 on SGLang. github.com/thu-nics/AKV

Google open-sourced its Elephant-Goldfish Model plugin: a context-rich Elephant session drafts a design doc, then stateless Goldfish agents attack it before any code is written. Apache 2.0; Google says thousands of engineers use it daily. github.com/google/elephant-g…
