Anthropic's latest SDK hints at new `claude-opus-4-8` and `claude-haiku-4-5` model IDs, beta features for rate limits and user profiles, and new organizational endpoints.
READY TO POST:
anthropic just updated their python sdk, and it looks like there are mentions of new model ids: `claude-opus-4-8` and `claude-haiku-4-5`. could these be coming soon?
diving into the new anthropic sdk (1.16.0) and spotting some interesting beta features around rate limits, user profiles, and new org-level endpoints. sounds like more control is coming!
