New release of LLM adds support for reasoning traces, OpenAI Responses, server-side tools, and smarter logging

<p>I released <a href="https://llm.datasette.io/en/stable/changelog.html#v0-32">LLM 0.32</a> 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 features enabled by the OpenAI Responses API. I also released new versions of the <code>llm-anthropic</code>, <code>llm-gemini</code>, and <code>llm-openrouter</code> plugins, each with substantial updates of their own.</p> <h4 id="headline-features-for-llm-cli-users">Headline features for LLM CLI users</h4> <p>Running LLM against reasoning models now <strong>displays their reasoning traces</strong> to standard error, so you can see what they are "thinking" without that information being included in the standard output that you might pipe to another tool. Add <code>-R/--hide-reasoning</code> to turn this off.</p> <p><img alt="Running llm &quot;think about the best thing about pelicans&quot; in the macOS terminal window - grey text outputs saying Exploring pelican qualities, then after a paragraph of that a white paragraph of text comes out saying: The best thing about pelicans is their wonderfully oversized, practical design: that enormous bill and pouch look comical, but they make pelicans remarkably skilled fishers. Even better, many species cooperate—working together to herd fish before scooping them up. They’re a great mix of goofy, graceful, and surprisingly clever." src="https://static.simonwillison.net/static/2026/best-pelicans.gif" /></p> <p>LLM includes support out-of-the-box for the <strong>GPT-5.6 model family</strong>, and the new default model used with <code>llm "prompt"</code> is now the inexpensive but capable <strong>GPT-5.6 Luna</strong>.</p> <p>LLM calls can now use <strong>server-side tools</strong> from various providers.
