Having Claude ask Codex for a second opinion when it gets stuck is mindblowing. I watch along as they have a little a conversation and the bug is fixed. I am firmly relegated to third place.

I created an open router MCP, which has modes like challenge, expand , reframe , so Claude can then ask various models for second opinions. I called it free thinker. By having Claude challenged it always comes back with new insight. Plus you can use Gemini 3 flash to generate images for use in Claude processes 😜
