Anthropic Releases Claude Opus 5 as Its New Default for Max
Anthropic introduced Claude Opus 5, describing stronger coding and knowledge-work performance at the same price as its predecessor.
Anthropic introduced Claude Opus 5, saying it approached the frontier intelligence of Fable 5 at half the price and improved coding and knowledge-work performance. The company made it the new default model for Claude Max and its strongest option for Claude Pro.
The release kept pressure on a familiar frontier-model trade-off: capability, cost and reliability must improve together if agents are to move from occasional use into everyday professional work. Lower cost at comparable performance is often what unlocks a wider deployment rather than a headline benchmark alone.
