- https://simonwillison.net/2026/Apr/27/now-deceased-agi-claus... pulled apart the absurd deal between OpenAI and Microsoft where OpenAI could declare "AGI" and Microsoft would lose their rights to that IP
- https://simonwillison.net/2026/Apr/23/gpt-5-5/ pointed out that, while OpenAI had said that GPT-5.5 was not yet available via their API for safety reasons, they also recently blessed accessing their unofficial Codex-only API as part of their attempt to tempt OpenClaw customers away from Anthropic... which meant they DID offer and approve of an API for GPT-5.5 after all
- https://simonwillison.net/2026/Apr/22/claude-code-confusion/ was highly critical of Anthropic's decision to A/B test the pricing of Claude Code, not to mention the messy way they had done that.
- https://simonwillison.net/2026/Apr/21/gpt-image-2/ pointed out how much worse the previously celebrated Nano Banana is as at image generation compared to ChatGPT Images 2.0, while also showing ChatGPT Images 2.0 will cheat and add a raccoon if you ask it to solve its own puzzle.
- https://simonwillison.net/2026/Apr/18/opus-system-prompt/ was the first coverage I saw anywhere of the new eating disorder section of the Claude system prompt. I also repeated my criticism there of Anthropic's decision not to publish their tool descriptions even when they claim to have an openly documented system prompt.

- https://simonwillison.net/2026/Apr/27/now-deceased-agi-claus... pulled apart the absurd deal between OpenAI and Microsoft where OpenAI could declare "AGI" and Microsoft would lose their rights to that IP
- https://simonwillison.net/2026/Apr/23/gpt-5-5/ pointed out that, while OpenAI had said that GPT-5.5 was not yet available via their API for safety reasons, they also recently blessed accessing their unofficial Codex-only API as part of their attempt to tempt OpenClaw customers away from Anthropic... which meant they DID offer and approve of an API for GPT-5.5 after all
- https://simonwillison.net/2026/Apr/22/claude-code-confusion/ was highly critical of Anthropic's decision to A/B test the pricing of Claude Code, not to mention the messy way they had done that.
- https://simonwillison.net/2026/Apr/21/gpt-image-2/ pointed out how much worse the previously celebrated Nano Banana is as at image generation compared to ChatGPT Images 2.0, while also showing ChatGPT Images 2.0 will cheat and add a raccoon if you ask it to solve its own puzzle.
- https://simonwillison.net/2026/Apr/18/opus-system-prompt/ was the first coverage I saw anywhere of the new eating disorder section of the Claude system prompt. I also repeated my criticism there of Anthropic's decision not to publish their tool descriptions even when they claim to have an openly documented system prompt.
- https://simonwillison.net/2026/Apr/16/qwen-beats-opus/ demonstrated the new Opus 4.7 drawing a worse pelican than an open weights model I can run on my laptop. (Though to be fair I manly concluded this as evidence that my own "benchmark" is of very limited value.)

My hunch is we'll need abstraction layers for quite a while longer, because the shape of these APIs is still too frothy to support a standard that everyone can get behind without restricting their options for future products too much.","created_at":"2026-04-21T17:41:10Z","created_at_i":1776793270,"objectID":"47851955","parent_id":47851488,"story_id":47849097,"story_title":"Show HN: GoModel \u2013 an open-source AI gateway in Go","story_url":"https://github.com/ENTERPILOT/GOModel/","updated_at":"2026-04-22T03:34:20Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"Looks more similar to routines for me (just launched the other day): https://code.claude.com/docs/en/routines"},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Show HN: Daemons \u2013 we pivoted from building agents to cleaning up after them"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://charlielabs.ai/"}},"_tags":["comment","author_simonw","story_47850907"],"author":"simonw","children":[47851950],"comment_text":"Looks more similar to routines for me (just launched the other day): https://code.claude.com/docs/en/routines","created_at":"2026-04-21T17:26:54Z","created_at_i":1776792414,"objectID":"47851805","parent_id":47851704,"story_id":47850907,"story_title":"Show HN: Daemons \u2013 we pivoted from building agents to cleaning up after them","story_url":"https://charlielabs.ai/","updated_at":"2026-04-21T21:03:20Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"I appreciated John Gruber's piece on this: https://daringfireball.net/2026/04/another_day_has_come"},"story_title":{"matchLevel":"none","matchedWords":[],"value":"John Ternus to become Apple CEO"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://www.apple.com/newsroom/2026/04/tim-cook-to-become-apple-executive-chairman-john-ternus-to-become-apple-ceo/"}},"_tags":["comment","author_simonw","story_47840219"],"author":"simonw","comment_text":"I appreciated John Gruber's piece on this: https://daringfireball.net/2026/04/another_day_has_come","created_at":"2026-04-21T04:24:04Z","created_at_i":1776745444,"objectID":"47844498","parent_id":47840219,"story_id":47840219,"story_title":"John Ternus to become Apple CEO","story_url":"https://www.apple.com/newsroom/2026/04/tim-cook-to-become-apple-executive-chairman-john-ternus-to-become-apple-ceo/","updated_at":"2026-04-21T12:17:33Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"Accessed via OpenRouter, this one decided to wrap the SVG pelican in HTML with controls for the animation speed: https://gisthost.github.io/?ecaad98efe0f747e27bc0e0ebc669e94...

From https://kamal-deploy.org/docs/upgrading/proxy-changes/ it looks like Kamal 2's new proxy doesn't have this yet, they list "Pausing requests" as "coming soon".","created_at":"2026-04-07T15:27:04Z","created_at_i":1775575624,"objectID":"47676854","parent_id":47676525,"story_id":47637353,"story_title":"SQLite in Production: Lessons from Running a Store on a Single File","story_url":"https://ultrathink.art/blog/sqlite-in-production-lessons","updated_at":"2026-04-10T18:56:37Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"https://theshamblog.com/an-ai-agent-wrote-a-hit-piece-on-me-... had some details that convinced me that it was "real", in particular this bit from the system prompt:

I certainly wouldn't call Claude Code "trivial" - it's by far the most sophisticated TUI app I've ever interacted with. I can drag images onto it, it runs multiple sub-agents all updating their status rows at the same time, and even before the source code leaked I knew there was a ton of sophistication in terms of prompting under the hood because I'd intercepted the network traffic to see what it was doing.

> Surely you can do better than an LLM when you write code yourself?
It takes me a solid day to write 100 lines of well designed, well tested code - and I'm pretty fast. Working with an LLM (and telling it what I want it to do) I can get that exact same level of quality in more like 30 minutes.
And because it's so much faster, the code I produce is better - because if I spot a small but tedious improvement I apply that improvement. Normally I would weigh that up against my other priorities and often choose not to do it.
So no, I can't do better that an LLM when I'm writing code by hand.
That said: I expect there are all sorts of crufty corners of Claude Code given the rate at which they've been shipping features and the intense competition in their space. I expect they've optimized for speed-of-shipping over quality-of-code, especially given their confidence that they can pay down technical debt fast in the future.

In case you're open to learning, here's why I think this is useful.
The big lesson we've learned from Claude Code, Codex CLI et al over the past twelve months is that the most useful tool you can provide to an LLM is Bash.
Last year there was enormous buzz around MCP - Model Context Protocol. The idea was to provide a standard for wiring tools into LLMs, then thousands of such tools could bloom.
Claude Code demonstrated that a single tool - Bash - is actually much more interesting than dozens of specialized tools.
Want to edit files without rewriting the whole thing every time? Tell the agent to use sed or perl -e or python -c.
Look at the whole Skills idea. The way Skills work is you tell the LLM "if you need to create an Excel spreadsheet, go read this markdown file first and it will tell you how to run some extra scripts for Excel generation in the same folder". Example here: https://github.com/anthropics/skills/tree/main/skills/xlsx
That only works if you have a filesystem and Bash style tools for navigating it and reading and executing the files.
This is why I want Linux in WebAssembly. I'd like to be able to build LLM systems that can edit files, execute skills and generally do useful things without needing an entire locked down VM in cloud hosting somewhere just to run that application.
Here's an alternative swipe at this problem: Vercel have been reimplementing Bash and dozens of other common Unix tools in TypeScript purely to have an environment agents know how to use: https://github.com/vercel-labs/just-bash
I'd rather run a 10MB WASM bundle with a full existing Linux build in then reimplement it all in TypeScript, personally."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"JSLinux Now Supports x86_64"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://bellard.org/jslinux/"}},"_tags":["comment","author_simonw","story_47311484"],"author":"simonw","children":[47329651,47323803],"comment_text":"> Well, there it is, the dumbest thing I'll read on the internet all week.

It still needs the full amount of memory though as the 3B active it uses are likely different on every iteration.","created_at":"2026-03-04T17:00:18Z","created_at_i":1772643618,"objectID":"47250423","parent_id":47250369,"story_id":47249343,"story_title":"Something is afoot in the land of Qwen","story_url":"https://simonwillison.net/2026/Mar/4/qwen/","updated_at":"2026-03-11T17:25:48Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"I've not really settled on one yet.

If you accelerate the pace of code creation it inevitably creates bottlenecks elsewhere. Code review is by far the biggest of those right now.
There may be an argument for leaning less on code review. When code is expensive to produce and is likely to stay in production for many years it's obviously important to review it very carefully. If code is cheap and can be inexpensively replaced maybe we can lower our review standards?
But I don't want to lower my standards! I want the code I'm producing with coding agents to be better than the code I would produce without them.
There are some aspects of code review that you cannot skimp on. Things like coding standards may not matter as much, but security review will never be optional.

We really aren't. I consistently argue for LLMs as tools that augment and amplify human expertise, not as tools that replace it.
I never repeat the "country of PhDs" stuff because I think it's over-hyped nonsense.

Something I've learned from this is that semantic diffusion is real, and the definition of a new term isn't what that term was intended to mean - it's generally the first guess people have when they hear it.
"Prompt injection" was meant to mean "SQL injection for prompts" - the defining characteristic was that it was caused by concatenating trusted and untrusted text together.
But people unfamiliar with SQL injection hear "prompt injection" and assume that it means "injecting bad prompts into a model" - something I'd classify as jailbreaking.
When I coined the term "lethal trifecta" I deliberately played into this effect. The great thing about that term is that you can't guess what it means! It's clearly\nthree bad things, but you're gonna have to go look it up to find out what those bad things are.

- Running Pydantic\u2019s Monty Rust sandboxed Python subset in WebAssembly https://simonwillison.net/2026/Feb/6/pydantic-monty/ - demonstrating how easy and useful it is to be able to turn Rust code into WASM that can run independently or be used inside a Python wheel for Pyodide in order to provide interactive browser demos of Rust libraries.
- Distributing Go binaries like sqlite-scanner through PyPI using go-to-wheel https://simonwillison.net/2026/Feb/4/distributing-go-binarie... - I think my go-to-wheel utility is really cool, and distributing Go CLIs through PyPI is a neat trick.
- ChatGPT Containers can now run bash, pip/npm install packages, and download files https://simonwillison.net/2026/Jan/26/chatgpt-containers/ - in which I reverse engineered and documented a massive new feature of ChatGPT that OpenAI hadn't announced or documented anywhere
