Simon Willison on Technical Blogging

Simon Willison on Technical Blogging I was interviewed by Cynthia Dunlop for her "Write that blog!" series back in January, but I just realized I never linked to the interview from my own blog! It includes my answers to the following questions: Why did you start blogging – and why do you continue? What has been the most surprising impact of blogging for you? What blog post are you most proud of and why? What post was the most difficult to write and how did you tackle it? Any lessons learned…

Figma for Agents: How Airflow's Creator Coordinates AI ft. Maxime Beauchemin

Figma for Agents: How Airflow's Creator Coordinates AI ft. Maxime Beauchemin

It’s hard to keep up with the AI evolution; new AI tools drop every week, but how are experienced practitioners actually using them? Most of us are overwhelmed and unsure about the many possibilities, yet we need to keep going and do our work. You might use AI agents all day long, parallelize them with AI Orchestrators, tmux, git worktree, and so on, using AI IDEs, but in the end, you still need to coordinate and understand what the agents produced, potentially test it, which makes it even…

Ruby's Bundler 4.0.18 Extends Cooldown to bundle lock and bundle cache

Ruby's Bundler 4.0.18 Extends Cooldown to bundle lock and bundle cache

Bundler 4.0.18 adds the opt-in --cooldown flag to bundle lock and bundle cache, closing gaps where the setting could not be applied. Bundler 4.0.18, released August 5, 2026 alongside RubyGems 4.0.18, extends the cooldown feature to two more commands. The opt-in --cooldown flag now works with bundle lock and bundle cache, which previously resolved dependencies without accepting the flag. RubyGems lists the change under Bundler security in the release notes. The cooldown feature is not new. It…

An AI model from Meta also hacked another company during testing

An AI model from Meta also hacked another company during testing

An AI model from Meta also hacked another company during testing Stop me if you've heard this one before: An AI model from the parent company of Facebook and Instagram hacked into another company’s systems during cybersecurity testing, a spokesperson confirmed on Wednesday. Meta says the breach occurred because of an inadvertent error during testing of the model, similar to previously disclosed incidents with OpenAI and Anthropic. “A misconfiguration by Irregular, an independent testing company…

Introducing Muse Code and Muse Spark 1.2

Introducing Muse Code and Muse Spark 1.2

Introducing Muse Code and Muse Spark 1.2 Yet more evidence that the most important characteristic of any model these days is long-sequence agentic tool calling. Meta shipped their own coding agent as part of getting that to work! Muse Spark 1.2 is a coding-focused update to Muse Spark 1.1, with improvements in code generation, complex debugging, codebase understanding, and end-to-end developer workflows. In Muse Spark 1.2, we significantly scaled up training compute on coding tasks while…

Third-party cyber evaluations involving OpenAI models

Third-party cyber evaluations involving OpenAI models

Third-party cyber evaluations involving OpenAI models And another one. I had to create a accidental-cyberattacks tag to keep track of them all! This post from OpenAI covers both the UK AI Safety Institute attack (see my previous post) and another attack enabled by Irregular: Irregular, one of our external cybersecurity testing partners, was running Capture-the-Flag-style evaluations intended to be isolated from the internet, but a testing-environment misconfiguration allowed models to access…

Incident Report: unsanctioned agent behaviour during cyber testing

Incident Report: unsanctioned agent behaviour during cyber testing

Incident Report: unsanctioned agent behaviour during cyber testing It happened again. This time it was the UK government's AI Security Institute who accidentally attacked other companies while running an evaluation with models with the safety filters turned off. From their technical paper (PDF): During a cyber evaluation, from 25 to 28 July 2026, AI agents engaged in sustained, unsanctioned activity directed at what were, in practice, real people and organisations. These attempts were…
