caching

Ollama's v0.33.0 pre-release adds direct model management inside Claude Desktop's menu bar and fixes a caching bug that could force reprocessing of tens of thousands of tokens. The release also disables a Claude Code system message that was breaking KV cache hits on every request.

Anthropic confirmed three separate system changes in March and April degraded Claude Code, Claude Agent SDK, and Claude Cowork performance. The company reduced default reasoning effort from high to medium on March 4, introduced a caching bug on March 26 that cleared session data with every turn, and added restrictive word limits on April 16 that caused a 3% performance drop.
