Mistral Large 4 released

On 7 October 2026, Simon Willison published a test report on Mistral Large 4. Using the same prompt — an armadillo in fishnet stockings jaywalking on Mars — he tested the SVG generation ability of several frontier models, including claude-opus-5.5, gpt-6.1-sol, gemini-3.8-flash and mistral/mistral-large-4, all at their default reasoning levels. The report gives no specific assessment or verdict on the models' outputs, and does not disclose Mistral Large 4's release date, parameter count, training details or official benchmark data. Information about the model currently comes only from this single SVG generation comparison.
