llm 0.37

LLM 0.37 is a release of Simon Willison's LLM CLI tool and Python library, covering about two months of changes. It adds gpt-6.1-sol and gpt-6.1-terra, a new `llm openai endpoint add` command for OpenAI-compatible endpoints, and a cheaper default model, gpt-6-luna. Embeddings now accept differing content types, as Gemini Embedding 2 needs. Willison says AI-assisted PRs from 12 authors were easy to review.

Claude Fable 5.5, GPT 6.2 Astra Could Be Right Around the Corner, Leaks Suggest

Decrypt reports unconfirmed signs of new frontier models as of 2 November 2026. Users say some Claude Opus 5.5 requests route to an unreleased "Fable 5.5". Evidence includes a "claude-fable-5-5" LiteLLM entry (13 October), a "Mythos 5.5" label in Anthropic page code (1 November), and "gpt-6.2-astra" in Codex usage data. Neither company has confirmed anything, and the entries were removed.

AI agent swarms in Minecraft fail to build civilization, drown in bureaucracy

Tom's Hardware reports on a ycombinator and Olam Labs experiment that ran LLM agent swarms in Minecraft. A 50-agent GPT-6.1 Sol team asked to build a civilization in three hours turned cautious and bureaucratic. In Bed Wars and Mindustry, GPT-6.1 Sol agents beat Claude Opus 5.5 agents (6-1 in Mindustry). The swarms are open sourced, built on Mindcraft and Mineflayer.

GPT-Rosalind-6 System Card Addendum

GPT-Rosalind-6 System Card Addendum is OpenAI's safety documentation for a life-sciences model that shares weights with GPT-6 Astra. It rates the model High in Biological and Chemical and Critical in Cybersecurity under the Preparedness Framework. It reports biology evaluations, trusted-access controls, biosecurity refusal pass rates, a historical cyber jailbreak regression (14.3% task success), and sabotage and monitor-evasion results.

Building a multiplayer game world with autonomous Fable-class models

Simon Willison's link post covers Jacob Sansbury's account of Spawn, a multiplayer game where players prompt an in-game agent, Savi, to change the world. Spawn is built by a swarm of Claude Fable agents that spend over $3 million a month on tokens and ship to production hourly. An hour without a ship counts as a SEV-0, and rollbacks take 30 seconds. Fable 5 and 5.1 made this autonomy work, Opus 5.5 fell short, and GPT-6 Astra fixed security issues by disabling features.

Can Frontier Models See Past a Decoy? Elorian Tests Visual Reasoning

DecoyCount is a benchmark from Elorian and Mercor with 1,660 items that tests whether models count objects or fall back on visual shortcuts. Frontier models scored below 50%: GPT-6 Astra led with 43.17%, ahead of Gemini-3.8-flash (32.71%), Qwen3.8-max (28.31%) and Claude-Fable-5.1 (25.22%). CEO Andrew Dai says Elorian's Glimpse model scored 50.48% in a single internal run without tools, and contrasts visual reasoning with world models such as Atlas and Genie 4.

Can LLMs Uncover Hidden Physical Laws through Free Exploration?

LongChang is an automated framework that builds simulated worlds with altered physical laws, such as heavier objects falling more slowly, to test whether LLMs can find the law by free exploration. Explorer LLMs manipulate objects and build tools without tasks or hints, while separate LLM agents generate scenes, review tool designs and grade reports. Across 12 LLMs, GPT-6 Astra reached a 16.7% discovery rate and the other 11 scored 0%.

GPT-6.1 Terra

GPT-6.1 Terra is OpenAI's midrange model, announced 26 October 2026 and aimed at visual reasoning, computer use and clearer writing. It costs $1 per million input tokens and $5 per million output, about half of GPT-5.6 Terra and GPT-6.1 Sol and roughly 10x GPT-6 Luna. Simon Willison relays OpenAI's Ted Sanders, who rates it better than Astra and Sol at technical communication and much faster on computer use.

OpenAI and Anthropic cut their LLM prices by up to 80% within a few months. Why?

Max Woolf's post (minimaxir.com, October 2026) gives a dated timeline of OpenAI and Anthropic price cuts from June to September 2026, including GPT-5.6 Luna down 80%, Opus 5.5 at $4 / $20 / $0.20 and GPT-6.1 Sol at $2 / $10 / $0.10. It argues the cuts come from commodity models, open-weight competition (DeepSeek V4.1 Flash, Kimi K3.1 Pro, 29 OpenRouter providers) and possibly IPO positioning. It notes cache reads make up 96-99% of coding-agent token spend.
