Gemini CLI vs Claude Code vs Codex CLI: Terminal AI Agents Compared
We benchmarked all three terminal coding agents on a real Express.js refactor. Claude Code finished in 1h17m, Codex CLI in 1h41m, Gemini CLI in 2h04m—here's what the numbers miss.

At Particula Tech, we build AI systems that work in production. Custom models, intelligent automation, and systems that improve as they learn from your data.
