🤖 Models

• Claude Opus 4.7 — Anthropic released Opus 4.7, now tied for #1 on Artificial Anlys’ Intelligence Index (57.3) alongside Gemini 3.1 Pro (57.2) and GPT-5.4 (56.8). The model scores a three-way tie at the top and leads on agentic benchmarks. Key improvements: ~35% fewer output tokens than Opus 4.6 at higher scores, full removal of extended thinking in favor of adaptive reasoning, and improved vision capabilities. Priced at $5/$25 per million tokens. Third-party benchmarks broadly favorable — #1 in both Code Arena and Text Arena — though early user reports noted some regressions that Anthropic patched within a day.

• GPT Rosalind — OpenAI introduced GPT-Rosalind, a biology-tuned LLM designed for drug discovery and scientific research. The model integrates with scientific data sources and features improved reasoning and tool use for biological research workflows.

• Qwen 3.6 — Alibaba’s Qwen team released 3.6 with stronger repository-level reasoning, better front-end workflow handling, and a thinking preservation feature that maintains context across iterations. Community is already building local agent stacks with llama.cpp + Pi setups using the 35B-A3B variant, and Red Hat released an NVFP4-quantized checkpoint.

• Ternary Bonsai — A 1.58-bit language model family (8B, 4B, 1.7B) offering near-full-precision performance at dramatically reduced memory footprint. Scores 75.5 on average benchmarks with 3-4x better energy efficiency. Apache 2.0 licensed, runs on Macs and iPhones.

🛠️ Agents & Tools

• Claude Design — Anthropic’s biggest product expansion since Claude itself. A research-preview design tool that generates prototypes, slides, and one-pagers from natural language, powered by Opus 4.7. Features inline refinement, slider controls, exports to Canva/PPTX/PDF/HTML, and handoff to Claude Code for implementation. Framed as a direct competitor to Figma/Lovable/Bolt/v0 — Figma’s stock dropped sharply on the news. Anthropic’s CPO subsequently left Figma’s board.

• Codex expands into full computer automation — OpenAI updated Codex with background computer control, multi-agent workflows, and deeper integration with developer tools. Practitioners report the computer-use capability is genuinely fast, able to drive Slack, browser flows, and arbitrary desktop apps. Greg Brockman framed Codex as becoming a full agentic IDE.

• Perplexity Personal Computer — Perplexity launched an AI platform that shifts from manual instruction execution to probabilistic goal completion. The agent uses deep web research as its foundation to autonomously evaluate reasoning paths and drive multi-step workflows, transforming the computer into an active orchestrator.

• Chrome AI Mode gets side-by-side browsing — Google updated AI Mode in Chrome to open webpages alongside AI responses, enabling continuous context while exploring and comparing content.

• Windsurf 2.0 — Added Devin and Agent Command Center features, bringing autonomous coding agent capabilities into the IDE workflow.

• Android CLI for agent-driven development — Google released tools to eliminate guesswork in Android development workflows when directing agent work outside Android Studio, claiming 3x faster app building.

🔬 Research & Engineering

• OpenClaw’s two sides — Peter Steinberger gave contrasting talks: a public TED version celebrating OpenClaw’s inspiring story, and a sober engineering talk about unprecedented security challenges — 60x more reports than curl, at least 20% of skill contributions malicious. The project is now the fastest-growing open-source project in history.

• Hermes Agent ecosystem thriving — Ollama shipped native Hermes support, and Nous + Kimi launched a $25k Hermes Agent Creative Hackathon, signaling a push from coding/productivity into creative agent workflows.

• HuggingFace Transformers-to-MLX porting tool — A new skill and test harness help port transformer models to mlx-lm, managing conversion tasks and providing agent-assisted PRs with comprehensive reports for maintainers.

• Sandboxed agents for codebase migration — OpenAI published a structured approach using sandboxed agents that operate on isolated tasks, validate changes, and return auditable patches while orchestration remains outside the execution environment.

• Cognitive Companion: monitoring agent reasoning — New research shows a logistic-regression probe on hidden states can detect reasoning degradation with AUROC 0.840 at zero inference overhead, while an LLM-monitor version cuts repetition 52-62% with ~11% overhead.

• Stargate on track for 9+ GW by 2029 — Epoch AI surveyed all 7 US Stargate sites and concluded the project is tracking toward 9+ GW of compute capacity, comparable to New York City’s peak power demand. Current global datacenter capex is roughly 5-7 Manhattan Projects per year in inflation-adjusted terms.

💰 Industry & Security

• OpenAI spending $20B+ on Cerebras chips — OpenAI will pay Cerebras more than $20 billion over the next three years for server infrastructure, and may receive an equity stake. OpenAI is also providing $1B for datacenter development. Cerebras is targeting a Q2 IPO.

• Jensen Huang on Anthropic, OpenAI, and China — NVIDIA’s CEO lost his composure during a discussion about whether chip sales to China should be restricted, revealing more than intended about the geopolitical tensions in AI supply chains.

• China tests undersea cable cutter — New Chinese technology can reportedly cut subsea cables at depths of up to 13,123 feet, raising alarm about the vulnerability of internet backbone infrastructure.

• US tech firms lobbied EU to hide datacenter emissions — Microsoft and US trade groups successfully pushed for legally questionable confidentiality clauses on datacenter emissions reporting, adopted almost word for word from their demands.

• Sam Altman’s home attacked — A Molotov cocktail attack on OpenAI CEO’s home comes amid growing public discontent against artificial intelligence.

• UK banks prepare to use Anthropic’s Mythos — The new Claude model, so far limited to US firms, is expanding to British financial institutions, prompting warnings from finance leaders.
