The Pelican comparison grid for Astra is pretty interesting

תקציר מקורי באנגלית<p>I got access to GPT-6 Astra this afternoon, so naturally I used it to generate <a href="https://simonwillison.net/tags/pelican-riding-a-bicycle/">SVGs of pelicans riding bicycles</a> - at low, medium, high, xhigh and max reasoning levels (Astra doesn't support reasoning=none). Then I rendered those pelicans in <a href="https://static.simonwillison.net/static/2026/gpt-6-and-5.6-pelicans.html">a comparison grid</a> with GPT-5.6 Sol, Terra, and Luna, and beyond being fun the result was surprisingly useful.</p> <p><img src="https://static.simonwillison.net/static/2026/gpt-6-and-5-6-pelicans-html.webp" alt="Comparison grid showing gpt-6-astra, gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna at 6 different reasoning levels with pelicans and token counts and prices for each one." style="max-width: 10
