Recommendations on AI Workflow

I heard that "Gemini-CLI" and GPT Codex are useful for working with larger projects in the terminal. Now there is also Gemini Conductor. I think ClaudeAI has a similar tool, but it uses not their latest AI Opus 4.5 for the cheap 20 $ subscription. I am subscribed only to Gemini and OpenAI (20$ each), and intend to test them soon. I think the Zed editor has also AI integration.
