Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.
It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
Grok 4.7 places @SpaceXAI as third, after Anthropic & OpenAI, for agentic coding.
When factoring in that Grok is significantly faster & lower cost, it’s a great choice for your everyday workhorse.
