I have yet to be able to get a single request that isn't downgraded to Opus-4.8 fairly quickly -- my most recent request (in Claude Desktop instead of Claude Code, hoping for better results) was "Please read and analyze my recent sessions, and let's discuss any themes and patterns you notice in my usage" -- somehow this was a threat.

I've found Claude and GPT have converged again. The LLMs are bound to be commoditized, in 6 months, some open-source LLM will step in.
