Questions
How much money can I save?
Our benchmarks show up to 50% cost savings. Your exact savings are measured on your own data during onboarding.
Does it work with any coding agent?
Yes. Fidius decides which model handles each session, so it works with Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI and any other agent your team uses, without changing how anyone works.
Is this an AI gateway or context shrinking tool?
No. A gateway forwards requests to the models you choose. Context tools shrink what you send. Fidius makes the decision itself: which model should handle each session. It runs on top of your existing gateway or Bedrock account.
How does the routing work?
We train the routing layer on your specific coding tasks. No data leaves your environment, and we do not retain any of it.
How do you know a cheaper model is accurate enough for my task?
During onboarding we define test criteria with you, and they are checked continuously on your tasks. We take task accuracy seriously: the router sends work to a cheaper model only when it is certain accuracy is maintained.
About
Agents now write much of the code. Fidius is an applied AI lab for the agentic era of software.
