When I woke up this morning I didn't think I'd be spending a bunch of time today getting familiar with Catholic theology, but here we are. Notes on Pope Leo XIV's encyclical on AI. https://simonwillis

Simon Willison discusses whether coding agents should automatically generate tests alongside the code they produce, addressing a key quality assurance consideration in AI-assisted development. This li

Fun new feature in Datasette 1.0a30 - a 'jump to' menu, also available by the '/' keyboard shortcut, which lets you type to jump to a database, table or canned query. It offers a hook so plugins can e

Given how much of the original 'bottle of water per generated email' water estimate came from guesses at the architecture of GPT-4, it would be very much in @OpenAI's interest to publish the architect

Simon Willison reflects on the disconcerting experience of unknowingly reading AI-written emails presented as human-authored, comparing it to deliberate deception. The post raises concerns about authe

Datasette, an open-source tool for exploring and publishing data, released a blog post detailing a new jump menu feature for 2026. The jump menu likely provides improved navigation and quick access to

Plugins can also affect the empty state of the new menu - the latest datasette-agent adds a form for kicking off a new agent conversation - live demo (if you sign in with GitHub) on https://agent.data

Simon Willison shares notes and script related to OpenClaw names on his website, discussing naming conventions or identifiers associated with OpenClaw systems. The post likely covers technical details

To prepare for my #PyConUS lightning talk this afternoon I decided to track down ALL of the names that @openclaw has used since November, using a script against its GitHub repo Warelay → CLAWDIS → CLA

Doing this is a great way to make a bonfire of your reputation A person I know (and who is? was? a good professional al) left an AI-generated comment under my LinkedIn post. Full-on AI slop. I asked:

Mitchell Hashimoto argues that programming languages have historically created vendor lock-in effects but are increasingly losing that characteristic, likely due to standardization, interoperability i

Mitchell's post here reminded me of a similar conversation I had recently about how cheap it can be to port native mobile apps to React Native using coding agents... and then port them back again late

Simon Willison shares a technique for using Large Language Models directly from the command line using a shebang (#!) syntax, allowing scripts to be executed with LLM processing without explicit comma

My Mac had less available memory than I expected, turned out the 'claude' Claude Code processes on this machine (running in various terminal windows) were consuming ~30GB on their own! The largest one

Simon Willison discovered how to use an LLM command-line interface tool in Unix shebang lines, enabling the creation of executable scripts written in English or natural language. This technique allows
