Described as a cheaper version of Opus 5.5 but still really incredible; compared favorably to ChatGPT which he had previously switched to
"Absolutely zero surprise — I continue to like Sonnet 5 for an OpenClaw agent chitchat experience. This always wins. I know Sonnet 5. For very pithy AI back-and-forth OpenClaw model, I just have not found anything better."
Compared against Grok 4.6 and ChatGPT 5.6 Sol in the Claire Weighted Index benchmark; ranked best for this specific use case
