Claude Sonnet 5.5 is coming, and it might be days away. Anthropic confirmed it with the Opus 5.5 launch: Sonnet 5.5 and Haiku 5.5 "will follow in the coming weeks" with many of the same upgrades. Leakers are pointing to Sept 30 / Oct 1, with the model reportedly already in partner testing. For reference, Opus 5.5 came in ~40% cheaper and 30%+ faster than Opus 5. If Sonnet gets the same treatment, it's a big deal for anyone building with it. Jsyk the "Sonnet 5.5 beats GPT-6 Sol" leak going around is fake. Those specs are just Sonnet 5's existing numbers.
