Claude Sonnet 5.5 landed on 28 September as the second Claude 5.5 model. Same token prices as Sonnet 5, but Anthropic says it needs far fewer tokens and costs up to 30% less per task while generating outputs over 30% faster. The page calls out polished documents, slides and spreadsheets, plus image understanding strong enough that it is the first Sonnet to beat Pokémon Red from screenshots alone.
What changed for makers is where you put everyday craft. Early testers described it as better to collaborate with than Sonnet 5. Anthropic's own demos show single-file HTML motion pieces (murmurations, sand dunes, clock-of-clocks) completing faster and cleaner. Unity and Epic quotes stress runtime-checked creative and gameplay work, not chat fluency.
