This is really sucks, it’s a bad move for Anthropic, OpenAI is allowing using their models in third parties apps and the china models as well …
I don’t believe Anthropic will win this battle.
I just want to use the tools in a way and customized way that I want, Anthropic not allowing me to me to do that forced me to use the codex models, thanks for that I’m very happy with the results. I’m cheering for OpenAI
I’ve been using this model for a while, and it’s very fast. It spent some time thinking but does fewer calls. For example, yesterday I asked the agent to find the Gemini quota limit for their API, and it took 27 seconds and just 2 calls, Opus 4.6 took 33 seconds, but 5 calls with less thinking
It’s different than this one shared by the op, but Anthropic maybe updated the prompt
