Simon tests its local execution capabilities and tool-calling proficiency, signaling another practical step forward for open-source AI developer tooling.</p> <h2 id="posts">Posts<a class="anchor" href="#posts">#</a></h2> <p><strong><a href="https://simonwillison.net/2026/Jun/29/ornith/#atom-everything">Ornith-1.0: Self-Scaffolding LLMs for Agentic Coding</a></strong> Simon goes hands-on with Ornith-1.0, a new MIT-licensed model family from DeepReinforce built on top of Gemma 4 and Qwen 3.5. Testing the 35B MoE variant locally via LM Studio, he finds it highly proficient at executing agent harnesses and running tool calls against a Datasette checkout. He highlights that the underlying models use clean Apache 2.0 licenses, successfully avoiding the &ldquo;janky&rdquo; terms of use that affected earlier Gemma models.</p>
