New dashboard: alt text for all my images. I got curious today about how I'd been using alt text for images on my blog, and realized that since I have Django SQL Dashboard running on this site and PostgreSQL is capable of parsing HTML with regular expressions I could probably find out using a SQL query.

I pasted my PostgreSQL schema into Claude and gave it a pretty long prompt:

Give this PostgreSQL schema I want a query that returns all of my images and their alt text. Images are sometimes stored as HTML image tags and other times stored in markdown.

blog_quotation.quotation, blog_note.body both contain markdown. blog_blogmark.commentary has markdown if use_markdown is true or HTML otherwise. blog_entry.body is always HTML

Write me a SQL query to extract all of my images and their alt tags using regular expressions. In HTML documents it should look for either <img .* src="..." .* alt="..." or <img alt="..." .* src="..." (images may be self-closing XHTML style in some places). In Markdown they will always be ![alt text](url)

I want the resulting table to have three columns: URL, alt_text, src - the URL column needs to be constructed as e.g. /2025/Feb/2/slug for a record where created is on 2nd feb 2025 and the slug column contains slug

Use CTEs and unions where appropriate

It almost got it right on the first go, and with a couple of follow-up prompts I had the query I wanted. I also added the option to search my alt text / image URLs, which has already helped me hunt down and fix a few old images on expired domain names. Here's a copy of the finished 100 line SQL query.

llm-fragment-symbex. I released a new LLM fragment loader plugin that builds on top of my Symbex project.

Symbex is a CLI tool I wrote that can run against a folder full of Python code and output functions, classes, methods or just their docstrings and signatures, using the Python AST module to parse the code.

llm-fragments-symbex brings that ability directly to LLM. It lets you do things like this:

llm install llm-fragments-symbex
llm -f symbex:path/to/project -s 'Describe this codebase'

I just ran that against my LLM project itself like this:

cd llm
llm -f symbex:. -s 'guess what this code does'

Here's the full output, which starts like this:

This code listing appears to be an index or dump of Python functions, classes, and methods primarily belonging to a codebase related to large language models (LLMs). It covers a broad functionality set related to managing LLMs, embeddings, templates, plugins, logging, and command-line interface (CLI) utilities for interaction with language models. [...]

That page also shows the input generated by the fragment - here's a representative extract:

# from llm.cli import resolve_attachment
def resolve_attachment(value):
    """Resolve an attachment from a string value which could be:
    - "-" for stdin
    - A URL
    - A file path

    Returns an Attachment object.
    Raises AttachmentError if the attachment cannot be resolved."""

# from llm.cli import AttachmentType
class AttachmentType:

    def convert(self, value, param, ctx):

# from llm.cli import resolve_attachment_with_type
def resolve_attachment_with_type(value: str, mimetype: str) -> Attachment:

If your Python code has good docstrings and type annotations, this should hopefully be a shortcut for providing full API documentation to a model without needing to dump in the entire codebase.

The above example used 13,471 input tokens and 781 output tokens, using openai/gpt-4.1-mini. That model is extremely cheap, so the total cost was 0.6638 cents - less than a cent.

The plugin itself was mostly written by o4-mini using the llm-fragments-github plugin to load the simonw/symbex and simonw/llm-hacker-news repositories as example code:

llm \
  -f github:simonw/symbex \
  -f github:simonw/llm-hacker-news \
  -s "Write a new plugin as a single llm_fragments_symbex.py file which
   provides a custom loader which can be used like this:
   llm -f symbex:path/to/folder - it then loads in all of the python
   function signatures with their docstrings from that folder using
   the same trick that symbex uses, effectively the same as running
   symbex . '*' '*.*' --docs --imports -n" \
   -m openai/o4-mini -o reasoning_effort high

Here's the response. 27,819 input, 2,918 output = 4.344 cents.

In working on this project I identified and fixed a minor cosmetic defect in Symbex itself. Technically this is a breaking change (it changes the output) so I shipped that as Symbex 2.0.

llm-fragments-github 0.2. I upgraded my llm-fragments-github plugin to add a new fragment type called issue. It lets you pull the entire content of a GitHub issue thread into your prompt as a concatenated Markdown file.

(If you haven't seen fragments before I introduced them in Long context support in LLM 0.24 using fragments and template plugins.)

I used it just now to have Gemini 2.5 Pro provide feedback and attempt an implementation of a complex issue against my LLM project:

llm install llm-fragments-github
llm -f github:simonw/llm \
  -f issue:simonw/llm/938 \
  -m gemini-2.5-pro-exp-03-25 \
  --system 'muse on this issue, then propose a whole bunch of code to help implement it'

Here I'm loading the FULL content of the simonw/llm repo using that -f github:simonw/llm fragment (documented here), then loading all of the comments from issue 938 where I discuss quite a complex potential refactoring. I ask Gemini 2.5 Pro to "muse on this issue" and come up with some code.

This worked shockingly well. Here's the full response, which highlighted a few things I hadn't considered yet (such as the need to migrate old database records to the new tree hierarchy) and then spat out a whole bunch of code which looks like a solid start to the actual implementation work I need to do.

I ran this against Google's free Gemini 2.5 Preview, but if I'd used the paid model it would have cost me 202,680 input tokens and 10,460 output tokens for a total of 66.36 cents.

As a fun extra, the new issue: feature itself was written almost entirely by OpenAI o3, again using fragments. I ran this:

llm -m openai/o3 \
  -f https://raw.githubusercontent.com/simonw/llm-hacker-news/refs/heads/main/llm_hacker_news.py \
  -f https://raw.githubusercontent.com/simonw/tools/refs/heads/main/github-issue-to-markdown.html \
  -s 'Write a new fragments plugin in Python that registers issue:org/repo/123 which fetches that issue
      number from the specified github repo and uses the same markdown logic as the HTML page to turn that into a fragment'

Here I'm using the ability to pass a URL to -f and giving it the full source of my llm_hacker_news.py plugin (which shows how a fragment can load data from an API) plus the HTML source of my github-issue-to-markdown tool (which I wrote a few months ago with Claude). I effectively asked o3 to take that HTML/JavaScript tool and port it to Python to work with my fragments plugin mechanism.

o3 provided almost the exact implementation I needed, and even included support for a GITHUB_TOKEN environment variable without me thinking to ask for it. Total cost: 19.928 cents.

On a final note of curiosity I tried running this prompt against Gemma 3 27B QAT running on my Mac via MLX and llm-mlx:

llm install llm-mlx
llm mlx download-model mlx-community/gemma-3-27b-it-qat-4bit

llm -m mlx-community/gemma-3-27b-it-qat-4bit \
  -f https://raw.githubusercontent.com/simonw/llm-hacker-news/refs/heads/main/llm_hacker_news.py \
  -f https://raw.githubusercontent.com/simonw/tools/refs/heads/main/github-issue-to-markdown.html \
  -s 'Write a new fragments plugin in Python that registers issue:org/repo/123 which fetches that issue
      number from the specified github repo and uses the same markdown logic as the HTML page to turn that into a fragment'

That worked pretty well too. It turns out a 16GB local model file is powerful enough to write me an LLM plugin now!

Claude Code: Best practices for agentic coding (via) Extensive new documentation from Anthropic on how to get the best results out of their Claude Code CLI coding agent tool, which includes this fascinating tip:

We recommend using the word "think" to trigger extended thinking mode, which gives Claude additional computation time to evaluate alternatives more thoroughly. These specific phrases are mapped directly to increasing levels of thinking budget in the system: "think" < "think hard" < "think harder" < "ultrathink." Each level allocates progressively more thinking budget for Claude to use.

Apparently ultrathink is a magic word!

I was curious if this was a feature of the Claude model itself or Claude Code in particular. Claude Code isn't open source but you can view the obfuscated JavaScript for it, and make it a tiny bit less obfuscated by running it through Prettier. With Claude's help I used this recipe:

mkdir -p /tmp/claude-code-examine
cd /tmp/claude-code-examine
npm init -y
npm install @anthropic-ai/claude-code
cd node_modules/@anthropic-ai/claude-code
npx prettier --write cli.js

Then used ripgrep to search for "ultrathink":

rg ultrathink -C 30

And found this chunk of code:

let B = W.message.content.toLowerCase();
if (
  B.includes("think harder") ||
  B.includes("think intensely") ||
  B.includes("think longer") ||
  B.includes("think really hard") ||
  B.includes("think super hard") ||
  B.includes("think very hard") ||
  B.includes("ultrathink")
)
  return (
    l1("tengu_thinking", { tokenCount: 31999, messageId: Z, provider: G }),
    31999
  );
if (
  B.includes("think about it") ||
  B.includes("think a lot") ||
  B.includes("think deeply") ||
  B.includes("think hard") ||
  B.includes("think more") ||
  B.includes("megathink")
)
  return (
    l1("tengu_thinking", { tokenCount: 1e4, messageId: Z, provider: G }), 1e4
  );
if (B.includes("think"))
  return (
    l1("tengu_thinking", { tokenCount: 4000, messageId: Z, provider: G }),
    4000
  );

So yeah, it looks like "ultrathink" is a Claude Code feature - presumably that 31999 is a number that affects the token thinking budget, especially since "megathink" maps to 1e4 tokens (10,000) and just plain "think" maps to 4,000.

openai/codex. Just released by OpenAI, a "lightweight coding agent that runs in your terminal". Looks like their version of Claude Code, though unlike Claude Code Codex is released under an open source (Apache 2) license.

Here's the main prompt that runs in a loop, which starts like this:

You are operating as and within the Codex CLI, a terminal-based agentic coding assistant built by OpenAI. It wraps OpenAI models to enable natural language interaction with a local codebase. You are expected to be precise, safe, and helpful.

You can:
- Receive user prompts, project context, and files.
- Stream responses and emit function calls (e.g., shell commands, code edits).
- Apply patches, run commands, and manage user approvals based on policy.
- Work inside a sandboxed, git-backed workspace with rollback support.
- Log telemetry so sessions can be replayed or inspected later.
- More details on your functionality are available at codex --help

The Codex CLI is open-sourced. Don't confuse yourself with the old Codex language model built by OpenAI many moons ago (this is understandably top of mind for you!). Within this context, Codex refers to the open-source agentic coding interface. [...]

I like that the prompt describes OpenAI's previous Codex language model as being from "many moons ago". Prompt engineering is so weird.

Since the prompt says that it works "inside a sandboxed, git-backed workspace" I went looking for the sandbox. On macOS it uses the little-known sandbox-exec process, part of the OS but grossly under-documented. The best information I've found about it is this article from 2020, which notes that man sandbox-exec lists it as deprecated. I didn't spot evidence in the Codex code of sandboxes for other platforms.

llm-fragments-rust (via) Inspired by Filippo Valsorda's llm-fragments-go, Francois Garillot created llm-fragments-rust, an LLM fragments plugin that lets you pull documentation for any Rust crate directly into a prompt to LLM.

I really like this example, which uses two fragments to load documentation for two crates at once:

llm -f rust:rand@0.8.5 -f rust:tokio "How do I generate random numbers asynchronously?"

The code uses some neat tricks: it creates a new Rust project in a temporary directory (similar to how llm-fragments-go works), adds the crates and uses cargo doc --no-deps --document-private-items to generate documentation. Then it runs cargo tree --edges features to add dependency information, and cargo metadata --format-version=1 to include additional metadata about the crate.

LLM pricing calculator (updated). I updated my LLM pricing calculator this morning (Claude transcript) to show the prices of various hosted models in a sorted table, defaulting to lowest price first.

Amazon Nova and Google Gemini continue to dominate the lower end of the table. The most expensive models currently are still OpenAI's o1-Pro ($150/$600 and GPT-4.5 ($75/$150).

llm-hacker-news. I built this new plugin to exercise the new register_fragment_loaders() plugin hook I added to LLM 0.24. It's the plugin equivalent of the Bash script I've been using to summarize Hacker News conversations for the past 18 months.

You can use it like this:

llm install llm-hacker-news
llm -f hn:43615912 'summary with illustrative direct quotes'

You can see the output in this issue.

The plugin registers a hn: prefix - combine that with the ID of a Hacker News conversation to pull that conversation into the context.

It uses the Algolia Hacker News API which returns JSON like this. Rather than feed the JSON directly to the LLM it instead converts it to a hopefully more LLM-friendly format that looks like this example from the plugin's test:

[1] BeakMaster: Fish Spotting Techniques

[1.1] CoastalFlyer: The dive technique works best when hunting in shallow waters.

[1.1.1] PouchBill: Agreed. Have you tried the hover method near the pier?

[1.1.2] WingSpan22: My bill gets too wet with that approach.

[1.1.2.1] CoastalFlyer: Try tilting at a 40° angle like our Australian cousins.

[1.2] BrownFeathers: Anyone spotted those "silver fish" near the rocks?

[1.2.1] GulfGlider: Yes! They're best caught at dawn.
Just remember: swoop > grab > lift

That format was suggested by Claude, which then wrote most of the plugin implementation for me. Here's that Claude transcript.

deepseek-ai/DeepSeek-V3-0324. Chinese AI lab DeepSeek just released the latest version of their enormous DeepSeek v3 model, baking the release date into the name DeepSeek-V3-0324.

The license is MIT (that's new - previous DeepSeek v3 had a custom license), the README is empty and the release adds up a to a total of 641 GB of files, mostly of the form model-00035-of-000163.safetensors.

The model only came out a few hours ago and MLX developer Awni Hannun already has it running at >20 tokens/second on a 512GB M3 Ultra Mac Studio ($9,499 of ostensibly consumer-grade hardware) via mlx-lm and this mlx-community/DeepSeek-V3-0324-4bit 4bit quantization, which reduces the on-disk size to 352 GB.

I think that means if you have that machine you can run it with my llm-mlx plugin like this, but I've not tried myself!

llm mlx download-model mlx-community/DeepSeek-V3-0324-4bit
llm chat -m mlx-community/DeepSeek-V3-0324-4bit

The new model is also listed on OpenRouter. You can try a chat at openrouter.ai/chat?models=deepseek/deepseek-chat-v3-0324:free.

Here's what the chat interface gave me for "Generate an SVG of a pelican riding a bicycle":

I have two API keys with OpenRouter - one of them worked with the model, the other gave me a No endpoints found matching your data policy error - I think because I had a setting on that key disallowing models from training on my activity. The key that worked was a free key with no attached billing credentials.

For my working API key the llm-openrouter plugin let me run a prompt like this:

llm install llm-openrouter
llm keys set openrouter
# Paste key here
llm -m openrouter/deepseek/deepseek-chat-v3-0324:free "best fact about a pelican"

Here's that "best fact" - the terminal output included Markdown and an emoji combo, here that's rendered.

One of the most fascinating facts about pelicans is their unique throat pouch, called a gular sac, which can hold up to 3 gallons (11 liters) of water—three times more than their stomach!

Here’s why it’s amazing:
- Fishing Tool: They use it like a net to scoop up fish, then drain the water before swallowing.
- Cooling Mechanism: On hot days, pelicans flutter the pouch to stay cool by evaporating water.
- Built-in "Shopping Cart": Some species even use it to carry food back to their chicks.

Bonus fact: Pelicans often fish cooperatively, herding fish into shallow water for an easy catch.

Would you like more cool pelican facts? 🐦🌊

In putting this post together I got Claude to build me this new tool for finding the total on-disk size of a Hugging Face repository, which is available in their API but not currently displayed on their website.

Update: Here's a notable independent benchmark from Paul Gauthier:

DeepSeek's new V3 scored 55% on aider's polyglot benchmark, significantly improving over the prior version. It's the #2 non-thinking/reasoning model, behind only Sonnet 3.7. V3 is competitive with thinking models like R1 & o3-mini.

simonw/ollama-models-atom-feed. I setup a GitHub Actions + GitHub Pages Atom feed of scraped recent models data from the Ollama latest models page - Ollama remains one of the easiest ways to run models on a laptop so a new model release from them is worth hearing about.

I built the scraper by pasting example HTML into Claude and asking for a Python script to convert it to Atom - here's the script we wrote together.

Update 25th March 2025: The first version of this included all 160+ models in a single feed. I've upgraded the script to output two feeds - the original atom.xml one and a new atom-recent-20.xml feed containing just the most recent 20 items.

I modified the script using Google's new Gemini 2.5 Pro model, like this:

cat to_atom.py | llm -m gemini-2.5-pro-exp-03-25 \
  -s 'rewrite this script so that instead of outputting Atom to stdout it saves two files, one called atom.xml with everything and another called atom-recent-20.xml with just the most recent 20 items - remove the output option entirely'

Here's the full transcript.

Building and deploying a custom site using GitHub Actions and GitHub Pages. I figured out a minimal example of how to use GitHub Actions to run custom scripts to build a website and then publish that static site to GitHub Pages. I turned the example into a template repository, which should make getting started for a new project extremely quick.

I've needed this for various projects over the years, but today I finally put these notes together while setting up a system for scraping the iNaturalist API for recent sightings of the California Brown Pelican and converting those into an Atom feed that I can subscribe to in NetNewsWire:

I got Claude to write me the script that converts the scraped JSON to atom.

Update: I just found out iNaturalist have their own atom feeds! Here's their own feed of recent Pelican observations.

Mistral Small 3.1. Mistral Small 3 came out in January and was a notable, genuinely excellent local model that used an Apache 2.0 license.

Mistral Small 3.1 offers a significant improvement: it's multi-modal (images) and has an increased 128,000 token context length, while still "fitting within a single RTX 4090 or a 32GB RAM MacBook once quantized" (according to their model card). Mistral's own benchmarks show it outperforming Gemma 3 and GPT-4o Mini, but I haven't seen confirmation from external benchmarks.

Despite their mention of a 32GB MacBook I haven't actually seen any quantized GGUF or MLX releases yet, which is a little surprising since they partnered with Ollama on launch day for their previous Mistral Small 3. I expect we'll see various quantized models released by the community shortly.

Update 20th March 2025: I've now run the text version on my laptop using mlx-community/Mistral-Small-3.1-Text-24B-Instruct-2503-8bit and llm-mlx:

llm mlx download-model mlx-community/Mistral-Small-3.1-Text-24B-Instruct-2503-8bit -a mistral-small-3.1
llm chat -m mistral-small-3.1

The model can be accessed via Mistral's La Plateforme API, which means you can use it via my llm-mistral plugin.

Here's the model describing my photo of two pelicans in flight:

llm install llm-mistral
# Run this if you have previously installed the plugin:
llm mistral refresh
llm -m mistral/mistral-small-2503 'describe' \
  -a https://static.simonwillison.net/static/2025/two-pelicans.jpg

The image depicts two brown pelicans in flight against a clear blue sky. Pelicans are large water birds known for their long bills and large throat pouches, which they use for catching fish. The birds in the image have long, pointed wings and are soaring gracefully. Their bodies are streamlined, and their heads and necks are elongated. The pelicans appear to be in mid-flight, possibly gliding or searching for food. The clear blue sky in the background provides a stark contrast, highlighting the birds' silhouettes and making them stand out prominently.

I added Mistral's API prices to my tools.simonwillison.net/llm-prices pricing calculator by pasting screenshots of Mistral's pricing tables into Claude.

Now you don’t even need code to be a programmer. But you do still need expertise. My recent piece on how I use LLMs to help me write code got a positive mention in John Naughton's column about vibe-coding in the Guardian this weekend.

Anthropic API: Text editor tool (via) Anthropic released a new "tool" today for text editing. It looks similar to the tool they offered as part of their computer use beta API, and the trick they've been using for a while in both Claude Artifacts and the new Claude Code to more efficiently edit files there.

The new tool requires you to implement several commands:

• view - to view a specified file - either the whole thing or a specified range
• str_replace - execute an exact string match replacement on a file
• create - create a new file with the specified contents
• insert - insert new text after a specified line number
• undo_edit - undo the last edit made to a specific file

Providing implementations of these commands is left as an exercise for the developer.

Once implemented, you can have conversations with Claude where it knows that it can request the content of existing files, make modifications to them and create new ones.

There's quite a lot of assembly required to start using this. I tried vibe coding an implementation by dumping a copy of the documentation into Claude itself but I didn't get as far as a working program - it looks like I'd need to spend a bunch more time on that to get something to work, so my effort is currently abandoned.

This was introduced as in a post on Token-saving updates on the Anthropic API, which also included a simplification of their token caching API and a new Token-efficient tool use (beta) where sending a token-efficient-tools-2025-02-19 beta header to Claude 3.7 Sonnet can save 14-70% of the tokens needed to define tools and schemas.

Cutting-edge web scraping techniques at NICAR. Here's the handout for a workshop I presented this morning at NICAR 2025 on web scraping, focusing on lesser know tips and tricks that became possible only with recent developments in LLMs.

For workshops like this I like to work off an extremely detailed handout, so that people can move at their own pace or catch up later if they didn't get everything done.

The workshop consisted of four parts:

1. Building a Git scraper - an automated scraper in GitHub Actions that records changes to a resource over time
2. Using in-browser JavaScript and then shot-scraper to extract useful information
3. Using LLM with both OpenAI and Google Gemini to extract structured data from unstructured websites
4. Video scraping using Google AI Studio

I released several new tools in preparation for this workshop (I call this "NICAR Driven Development"):

• git-scraper-template template repository for quickly setting up new Git scrapers, which I wrote about here
• LLM schemas, finally adding structured schema support to my LLM tool
• shot-scraper har for archiving pages as HTML Archive files - though I cut this from the workshop for time

I also came up with a fun way to distribute API keys for workshop participants: I had Claude build me a web page where I can create an encrypted message with a passphrase, then share a URL to that page with users and give them the passphrase to unlock the encrypted message. You can try that at tools.simonwillison.net/encrypt - or use this link and enter the passphrase "demo":

monolith (via) Neat CLI tool built in Rust that can create a single packaged HTML file of a web page plus all of its dependencies.

cargo install monolith # or brew install
monolith https://simonwillison.net/ > simonwillison.html

That command produced this 1.5MB single file result. All of the linked images, CSS and JavaScript assets have had their contents inlined into base64 URIs in their src= and href= attributes.

I was intrigued as to how it works, so I dumped the whole repository into Gemini 2.0 Pro and asked for an architectural summary:

cd /tmp
git clone https://github.com/Y2Z/monolith
cd monolith
files-to-prompt . -c | llm -m gemini-2.0-pro-exp-02-05 \
  -s 'architectural overview as markdown'

Here's what I got. Short version: it uses the reqwest, html5ever, markup5ever_rcdom and cssparser crates to fetch and parse HTML and CSS and extract, combine and rewrite the assets. It doesn't currently attempt to run any JavaScript.
