Frequently Asked Questions
Caveman vs Cognition AI: which should you choose?
If you manage a large enterprise codebase and need an autonomous agent that handles the entire SDLC with guaranteed ROI, Devin (Cognition AI) is your pick. If you're a solo dev or small team using AI coding tools and want to slash API costs while keeping output concise, Caveman is a free, lightweight no-brainer. They complement rather than compete directly.
Can Caveman work without Claude?
Yes, it supports Codex, Gemini, Cursor, Windsurf, Cline, Copilot, and 30+ other agents — any assistant that accepts system prompts.
Does Devin require an existing CI/CD pipeline?
No, Devin can autonomously plan, code, test, and create PRs. It integrates with GitHub and Slack but doesn't rely on your existing pipeline.
Is Caveman's token reduction consistent across all models?
Typically 65-75%, but varies by grunt level (lite, full, ultra, wenyan) and the model's adherence to terse instructions.
What is FrontierCode?
Announced June 8, FrontierCode is a new eval by Cognition that measures whether code is merge-worthy (not just syntactically correct), raising the bar for autonomous agent quality.
Does Caveman affect code correctness?
No — it only compresses conversational fluff. Technical code, commands, and error messages remain intact; tests pass as before.
How does Devin's productivity guarantee work?
Cognition offers up to $10M back if Devin doesn't deliver measurable productivity gains, based on their human-equivalent hour measurement system.
Can I use Caveman with Devin?
Caveman is a plugin for third-party assistants; Devin is a standalone agent. They are not directly integrated, but you could use Caveman on top of Devin's output if you pipe through another assistant.
What is Devin Desktop?
Launched June 2, it's a next-gen IDE (Windsurf) combined with Devin Cloud and Agent Command Center, giving enterprise teams a unified interface for autonomous coding.
