An unverified rumor claims Claude Opus 5.5 may launch this week.
The poster also argues Anthropic still lacks an answer to the competing "5.6 Luna," which is already capable enough for basic agentic coding tasks, and hopes for a very cheap, very fast Haiku-class model to power coding subagents — reflecting real demand for low-cost models in high-call-volume agent workflows.
