Includes new features enabled by LLM 0.32:
New models: claude-fable-5, claude-sonnet-5, and claude-opus-5. #75, #76
Added server-side tools for WebSearch, WebFetch, CodeExecution, and AnthropicMCP, available through LLM's -T interface o...
Back in 2022 I tweeted screenshots of a game concept generated by GPT-3 and some concept "art" created using DALL-E. Today, on the fourth anniversary of that tweet, I decided to see if Claude Fable 5 (running in Claude Code for web) could build the entire game from the conte...
I released LLM 0.32 this morning, the most significant new version of LLM since the initial launch of the project. The new version includes support for visible reasoning traces, server-side provider tools, redesigned content-addressable SQLite logs, new models, and new featu...
After shipping condense-json 1.0 I started integrating it into LLM, and found there were some desirable new features already:
Replacements object can now include values other than strings. These will be identified and used as structural replacements by condense_json() and uncondense_json(). #8
Objects can be used as the basis for merge operations. condense_json() will identify if there are objects that are a close match and will store instructions for keys to update or delete. uncondense_json() can then apply these merges.

PipeNetwork/minimax-h3-mlx
MiniMax released MiniMax-H3 two days ago - they describe it as a "a general-purpose, omni-modal generative system", which in practice means it accepts text, images, audio and video and can use them to generate up to 15 second video clips with audio...

Gas Town was intended to be reusable, but I only ever wound up using it to build itself. Gas Town fell apart at the seams with Opus 4.7. Up through 4.6 it was working brilliantly. With 4.7 we saw the introduction of the "just two more things" tic, which prevented Opus from ever converging on being ready to do real work—it always wanted to fiddle with Gas Town itself. The Opus tic never went away, so Gas Town effectively burned down. It had other problems, too, but 4.7 was the final straw.

Niklas Gruhn coins an excellent new term - meat proxy - for people who blindly copy and paste the output of AI systems to their peers.
By all means, prompt AI. But don't just relay the output. Read it, understand it, validate it, and then write a response in your own words (a decent certificate that you've done the prior steps). Making that effort is value you can add.
My comment on Devtools must be open source (exe.dev) — Hacker News.
One of the arguments for open source software for end-users has always been the freedom to examine and modify how that software works.
The reality for most people - even expert programmers - has been that th...
Set up a nightly cron job that executes the prompt: fetch upstream changes to the <software> and rebase all local changes on top of upstream. Check that the software works as intended and replace the current version.
Release: condense-json 1.0
I'm trying to get braver at releasing 1.0 versions. This little library is a year and a half old now - I've applied some sensible and non-disruptive fixes and shipped the big 1.0 for it.
Here's an example of what it can do, lifted from the ...
Open letters about AI development
I wrote this summary of the past few weeks of open letters as a section of my sponsors-only newsletter but I've decided to share it here as well.
Open Weights and American AI Leadership was shepherded by Microsoft, dated July 24th, and signe...
at openai, many people hook their chatgpt up to slack.
people really don't like when a coworker's chatgpt contacts them asking for help with a task, even when they'd be perfectly happy doing that same work if asked by that coworker.
reinforces how much people care about human relationships and helping each other, and want AI to give time back — or enhance time together — rather than become a layer separating people.
Changes that improve Datasette Apps when created and edited using Datasette Agent:
New app_debug() tool allowing agent to open an app (invisibly) and test it using JavaScript. #33
New app_list() tool for listing apps the user has permission to edit, so the agent can edit them. #36
The app_debug() tool is pretty neat: it works by displaying the app in a opacity: 0 iframe with pointer-events: none (so it can't be seen or interacted with) and then executing agent-provided JavaScript inside that sandboxed iframe. This means the agent can smoke test that the app is working and even do things like measure the dimensions of different elements.
Ten advances in mathematics and theoretical computer science
A few days ago it was Anthropic discovering cryptographic weaknesses with Claude using Mythos Preview, spending $100,000 on tokens and with prompts that included "again we are not looking for low hanging fruit, we ...
I wanted to create a new Slack emoji, and their tool recommends a square that's 128x128 and has a transparent background... so I had Fable build me this simple image editor against those requirements.
New await context.browser_task() mechanism allowing agent tools to run code directly in the user's browser. #33
This is an exciting new capability: it makes it easy for Datasette Agent plugins to provide tools that execute custom JavaScript in the user's browser.
deepseek-ai/DeepSeek-V4-Flash-0731
The latest release in DeepSeek's V4 family, "with substantially enhanced agentic capabilities". It's 304 billion parameters - 167GB on Hugging Face - but it appears to punch well above its weight.

Tuesday was Stateless MCP day - the rollout of MCP 2.0, or the 2026-07-28 Model Context Protocol specification to use the more formal but less memorable name. This is the most significant change to the MCP spec since it first launched, and has also served to reignite my pers...

Advancing the price-performance frontier with GPT‑5.6
Huge price drop from OpenAI today: GPT-5.6 Terra got a 20% reduction, and GPT-5.6 Luna got a massive 80% drop.

Investigating three real-world incidents in our cybersecurity evaluations
It happened again! This is turning into something of a pattern.
