How To Optimize Your Usage: The Best AI Models to Use, version 3.0

• GPT-5.2 XHigh: main developer
• GPT-5.1 Codex Max XHigh: for fast and simple tasks
• GPT-5.2 Codex: test writer
• Gemini 3 Pro/Flash: for discussions and chatter in Ai Studio without project context

I tried Cursor’s GPT-5.2 XHigh and GPT-5.1 Codex Max XHigh for writing tests – and I got the feeling I’d spend more money on tests than on the code itself.

My current list:
(GPT-5.2 XHigh (~= 5.2 Codex XHigh?) ~=$$ Claude Opus 4.5 Thinking) $> Gemini 3 Flash $> GPT-5 Mini > Grok Code Fast

(Continuously Updated) My Real-Time Review of Cursor Subagents

Testing subagents from the Cursor Nightly build. I tried building a search agent based on Grok Code Fast. The primary agent was GPT-5.2 XHigh. Conclusion: GPT-5.2 XHigh fills context more efficiently when performing the search itself than when reading context based on instructions from others. However, it can be suggested to use a search agent based on GCF, Gemini 3 Flash, or Claude Haiku for the second search pass. I’ll let you know if I have any further details on this subagent.
