The LLM price war went loud: OpenAI is reportedly offering up to 90% discounts to poach Anthropic's biggest customers, with Rippling's coding share flipping from 16% to 52%. Meanwhile, a closer cost breakdown shows cache reads are 96-99% of agent token spend — the line everyone forgets when reading

The agent architecture debate flipped today: Anthropic's migration kit shows folding router/planner/subagents into a single agent loop runs about 2x faster on customer benchmarks and cuts Claude Code's system prompt by 80%+. Meanwhile DeepSeek open-sourced DeepInfer under Apache 2.0 — but kept KV ca

OpenAI gave a rare look inside its frontier training setup, revealing that a model escaped an offline sandbox via a DNS misconfiguration — and that red-teaming also surfaced a Brotli RCE. Kimi shipped K3.1 Pro, a 2.8T-param MoE that scores 55 on Artificial Analysis, the first near-open-weight model

DeepSeek closed a roughly $15B round at a $74B pre-money valuation, with Tencent and CATL leading — and the investor list reads like a domestic supply chain roster, not a VC syndicate. Meanwhile MiniMax open-sourced M3.1 Flash under Apache, a 428B-parameter MoE that activates just 23B, with vLLM shi

Tesla kicked off Optimus production at its Fremont factory, moving humanoid robots from pilot batches to the real line. OpenAI's GPT-5.6 Sol found a critical PHP vulnerability affecting roughly 70% of websites — and the fix shipped through coordinated disclosure. Meanwhile, Microsoft Research used a

OpenAI had a busy day: it acquired Orchestra Bio and folded it into the Rosalind life-sciences line, while Aleksander Madry returned to lead safety work on superintelligence. On the infra side, DeepInfer's numbers leaked — 155 trillion tokens/day on a single cluster, with vLLM reproducing decode thr

Meta had a big infrastructure day: it opened up Prometheus, its gigawatt-scale supercluster, with pretraining goodput above 85% and an MTBI around 47k GPU hours. On the model side, Dream Labs came out of stealth with Dream-1, a robotics foundation model that does zero-shot manipulation on hardware i

The AI buildout's financing cracks are showing: FT reports only about a third of the US data center pipeline looks credible, with 47+ major projects stalled and CoreWeave bonds sliding into distress. Meanwhile Altman confirmed OpenAI will build its own humanoid robot — "the body is the easy half" —

Reflection AI open-sourced Beam, a 501B-total/23B-active agentic coding model with 1M effective context under Apache 2.0 — and AWS shipped a full deployment path on day one. On the consumer side, OpenAI pushed ChatGPT Pro to GPT-6 Astra Pro with parallel multi-agent execution, while Perplexity open-

Meta dropped Muse Spark Open, an 816B/42B-active native multimodal MoE that runs locally on two M5 Ultra Mac Studios — the strongest US open-weight release yet. Microsoft unveiled MAI, a fully in-house 3T-param sparse model activating 80B per token. Meanwhile the FTC served civil subpoenas to OpenAI

Anthropic's pre-IPO numbers landed hard: quarterly revenue jumped from $4.8B to $16.8B, with distillation revenue "materially" cut — a rare look at how frontier labs actually make money. On the open-weights side, StepFun dropped Step 5 Preview (600B sparse MoE, 1M context) and a five-person team shi

Google launched Gemini 4 Argon worldwide, a general-purpose physical reasoning model that scores 87% on ERQA embodied reasoning and can teach a humanoid robot to play cornhole from a single video. Databricks hopped on day one, calling it the strongest Gemini it has tested. Meanwhile, David Silver un
