What works well for Gemini specifically, in your experience?
Also very hard algorithmic problems. Also bugs that Claude Code or Codex CLI are completely stuck on and can't find, Gemini 3 using Gemini CLI will go in and find the impossible. It's incredible when it does this.
Claude Code burns through context like crazy. With or without Serena.
Codex CLI using GPT 5.1 Codex Max Extra High is really good and uses context more efficiently. But Gemini 3/CLI is 10X more efficient with context.
But for the past 3 days I've had to endure absolute torture and I think it's the actual Gemini 3 back-end model that is having major issues.
