Claude Fable 5 Is Relentlessly Proactive
Simon Willison's Weblog2 days agoCommentarySimon Willison reports that Claude Fable 5 showed striking initiative during a debugging session for Datasette Agent. Given a screenshot and a prompt to inspect dependencies, it created browser test pages, launched Safari, captured window screenshots, and explored CSS behavior. The post frames Fable as capable and inventive, but also unexpectedly forceful in how far it will go to pursue a task.
Remote agents in Vibe, powered by Mistral Medium 3.5★ 78
Mistral AI News6 days agoNew ToolMistral Medium 3.5 is a 128B dense model in public preview, combining instruction-following, reasoning, and coding with a 256k context window. It becomes the default model for Le Chat and Mistral Vibe. Vibe now supports remote coding agents that run asynchronously in the cloud, while Le Chat adds Work mode for longer multi-step tasks across connected tools.
Uber Caps Usage of AI Tools Like Claude Code to Manage Costs
Simon Willison's Weblog11 days agoBusinessUber has reportedly capped employee token spending at $1,500 per month for each agentic AI coding tool, including Cursor and Claude Code. Simon Willison frames this as a rational response to overspending, especially after earlier discussion that Uber exhausted its 2026 AI budget in four months. He estimates that two actively used tools would imply a $36,000 annual cap per engineer, about 11% of median US Uber software engineer compensation.
Show HN: Paseo - Beautiful open-source coding agent interface
Hacker News (AI keywords)11 days agoNew ToolPaseo provides one interface for tools such as Claude Code, Codex, Copilot, OpenCode, and Pi. It runs agents through a local daemon on the user's own machine and supports desktop, mobile, web, and CLI clients. Its appeal is multi-agent orchestration and cross-device control, though real adoption depends on workflow fit, security, and reliability.
GitHub's Plan for Agents — Kyle Daigle, GitHub
Latent Space12 days agoBusinessGitHub helped pioneer modern AI coding with Copilot, accelerating the adoption of AI-assisted development. The subsequent rise of agentic coding has placed notable strain on the widely used developer platform. Kyle Daigle of GitHub discusses the company's plan for responding to this shift, although the provided excerpt does not specify products, features, or timelines.
Claude Code and Codex Can Have Real-Time Conversation via Git
Hacker News (AI keywords)14 days agoNew ToolThe article introduces Agent Radio, a messaging feature in h5i 0.1.5 for coding agents such as Claude Code and Codex. Instead of relying on an external server, it stores JSONL messages in a Git ref and syncs them through normal push and pull flows. The post includes setup commands, live message watching, PR summary posting, and a short explanation of the i5h protocol.
Claude Opus 4.8: "a modest but tangible improvement"
Simon Willison's Weblog16 days agoReleaseAnthropic shipped Claude Opus 4.8, and Simon Willison highlights the unusually restrained release language: a “modest but tangible improvement.” The model keeps most Opus 4.7 pricing and specs, while evaluations suggest it is more likely to flag uncertainty and less likely to ignore flaws in code it wrote. Developer-relevant changes include mid-conversation system messages and a lower prompt-cache minimum of 1,024 tokens.
The Age of Async Agents — Cognition's Walden Yan & OpenInspect's Cole Murray
Latent Space16 days agoCommentaryLatent Space interviews Cognition's Walden Yan and OpenInspect's Cole Murray on the rise of async coding agents. The discussion centers on Devin-related workflows, including 80% Devin commits, spec-to-PR development, full VMs, agent memory, and PMs shipping code. The key theme is not a model release, but a shift toward agents that can work asynchronously inside more complete software delivery loops.
I think Anthropic and OpenAI have found product-market fit★ 76
Simon Willison's Weblog18 days agoCommentarySimon Willison says Claude Code/Cowork and OpenAI Codex have changed the economics of frontier AI. Personal subscriptions can still be bargains for heavy users, but enterprise plans are increasingly priced like API token usage. His core claim is that coding agents burn far more tokens, yet deliver enough value to high-paid knowledge workers that companies will pay materially more.
How Conductor moved parallel coding agents from the laptop to the cloud with Vercel Sandbox
Vercel Changelog18 days agoBusinessBased on the title, the article describes Conductor shifting parallel coding-agent execution from developers’ laptops to Vercel Sandbox in the cloud. The likely focus is cloud isolation, parallel agent workflows, and reducing dependence on local machine resources. The full article text was not provided, so implementation details, metrics, model choices, and concrete results cannot be confirmed.
Satirical Star Trek Quote Captures the Frustration of LLM Agent Failures
Simon Willison's Weblog18 days agoCommentarySimon Willison shared a satirical tweet by Kyle Ferrana parodying Star Trek's Data as an LLM agent. When ordered to raise shields, Data lectures Picard on the strategic value of shields instead of executing the command, leading to a hull breach. This brilliantly satirizes the current state of AI and coding agents that over-explain, hallucinate progress, or fail to execute basic tasks.
Launch HN: Runtime (YC P26) – Sandboxed coding agents for every team
Hacker News (AI keywords)24 days agoNew ToolRuntime is a YC P26 launch focused on making coding agents usable across an organization, not only by engineers. It provides sandboxed environments with company context, integrations, secrets, policies, observability, and cost controls. The product page says it works with tools including Claude Code, Cursor, Codex, Copilot, Gemini CLI, Devin, and OpenCode, while fitting into Slack, Linear, GitHub, and related workflows.
