GPT-6 and Claude 5.5, Gemini 4 Argon, Mistral and Beam previews, agent protocols, new tools, AI-generated mathematics, and virtual biology: September 22–October 8, 2026.
Hugging Face and Liquid AI train a 2.6B model across four agent harnesses, raising held-out task success from 42.2% to 54.2% while reducing tool calls.
Everyone from Pace the Frontier on the classic 3×3 alignment grid: who should referee AI’s pace (the law, the labs, or nobody) and where they stand on slowing it down (pace, neutral or accelerate).
A community-maintained Hugging Face Space, the Jev Decision Index, tracks and benchmarks all open-source reproductions of TypeSafe's Jev decision model, with a leaderboard, categorization, and trending metrics.
Liquid AI announced d1, its first decision model, claiming it is the first to surpass Jev on Hugging Face’s Decision Index. It is available through the Liquid API, with OpenRouter support planned.
OpenAI’s DevDay 2026 brought GPT-6.1 Sol, Decisions API, expanded agent and Codex tools, dots, plugins, shared ChatGPT workspaces, and new subscription options.
Trump’s White House AI lunch produced a voluntary safety accord and an executive order adopting “Super Intelligence” in federal communications. The CEOs’ seating chart drew contrasting political reactions on X.
NVIDIA announced the Open Agent Safety Platform, combining OpenShell and Sentry to provide hardware-enforced guardrails for AI agents, with over 100 industry partners including Anthropic and SpaceX but notably not OpenAI, Google, or Meta.
TBPN reports an $8.2 billion AMD acquisition of World Labs; deal terms and timing remain unspecified.
Anthropic released Claude Sonnet 5.5, the second model in the Claude 5.5 family, offering a clear upgrade over Sonnet 5 with 30%+ faster performance and up to 30% lower cost for most tasks.
Diogo Almeida joins swyx on Latent Space days after Jev’s launch to argue the next wave of AI will not look like chat: System One Models built for code, calibrated decisions and intelligence per dollar rather than benchmark scores.
Anthropic introduced Claude Opus 5.5, the first model in its Claude 5.5 family, claiming it matches Claude Fable 5.1 on most work while costing 40% less to run than Opus 5, with best-ever results on its automated behavioral audit.
We believe the next chapter of human flourishing will be built on open source software, decentralized organizations, and deeper human connection.

OpenAI introduced GPT-6 Sol and Luna, two new models that bring the intelligence advances of GPT-6 Astra to faster, more affordable tiers, with API prices cut 50% from GPT-5.6 promotional pricing.
Dan Hendrycks proposes eigenism: identity as a graded, distributed pattern, and outcomes scored as everyone’s wellbeing weighted by how much of your pattern they carry. Its safety upshot is that personalization and privacy become alignment tools.
Diogo Almeida, who co-invented ChatGPT, spent two years in stealth on a new training method (RLCD) and a new kind of model, Jev: a fast, cheap "decision" model meant to sit beside LLM calls rather than replace them. An early user ran 5,000 requests for…
“The Last AI Built by Humans”, from Shanghai Jiao Tong, Tsinghua, ByteDance and others, lays out five stages of autonomy on the way to AI that improves the process by which it improves itself — a research roadmap, not a system, published the weekend US…
ModularRSI evolves five parts of an agent harness separately, then combines them to test whether improvements transfer to unseen tasks and different models.
Cursor detailed the multi-agent harness that built a browser from scratch, peaking at roughly 1,000 commits an hour across 10 million tool calls over a week of unattended running.
Amodei’s pacing proposal, the evidence behind it, and the dispute over openness and oversight. Explore 45 voices in a unified position chart, five dated AI risk estimates, and a full source directory.
Astra ships and Amodei asks everyone to slow down. The Hugging Face postmortem, Fable 5.1, Fermat in Lean, the distillation report, the China front, Nvidia–Hugging Face, Cursor's swarm, robotics and hardware — plus Jev's classifier comeback and the papers on how agents actually fail.
