    This is the page for the &quot;max&quot; reasoning setting. The page for xhigh is <a href="https:&#x2F;&#x2F;artificialanalysis.ai&#x2F;models&#x2F;claude-opus-5-5-xhigh" rel="nofollow">https:&#x2F;&#x2F;artificialanalysis.ai&#x2F;models&#x2F;claude-opus-5-5-xhigh and the page for medium (the default setting) is <a href="https:&#x2F;&#x2F;artificialanalysis.ai&#x2F;models&#x2F;claude-opus-5-5-medium" rel="nofollow">https:&#x2F;&#x2F;artificialanalysis.ai&#x2F;models&#x2F;claude-opus-5-5-medium

    I&#x27;ve failed twice to get &quot;Generate an SVG of a pelican riding a bicycle&quot; to work with max, because in both cases it ran out of the 128,000 token budget while it was still reasoning about the problem.

    I&#x27;m suspicious that &quot;max&quot; may be virtually useless if it&#x27;s that easy to have it overthink to the point that it doesn&#x27;t get to a response.

    Transcript for one attempt here - expand the &quot;Reasoning trace&quot; bit to see it: <a href="https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=https%3A%2F%2Fgist.github.com%2Fsimonw%2F61fd7c3683fffce9a3ab7c43d1180024#reasoning-3" rel="nofollow">https:&#x2F;&#x2F;tools.simonwillison.net&#x2F;markdown-svg-renderer?url=ht...

      I&#x27;ve asked Opus 5 Max for what I thought were easy tasks at work to be completed. It always fails after reaching a tool limit.

      I asked Opus 5 High for the same task and requested it to minimize tool usage. It produced an answer in a few minutes that I was deploying to my target platform about 30 minutes later.
