# Modeless

> Modeless picks the model for your coding agent. Auto routes each session to the model it needs; Fusion combines several models into one answer. Model cost + 5%.

Modeless is a model gateway for coding agents. It exposes two models, `auto` and `fusion`, over three APIs (OpenAI Chat Completions, Anthropic Messages, OpenAI Responses) at https://api.modeless.ai. Pricing is the underlying model cost plus 5%. Every page below is also available as Markdown; the full site in one file is at https://modeless-web.vercel.app/llms-full.txt.

## Product

- [Auto: one model string for long coding-agent sessions](https://modeless-web.vercel.app/auto.md): Auto starts each coding-agent session on a fast, inexpensive model and moves to a stronger one when the work calls for it. At most one switch per session, so the prompt cache stays warm.
- [Fusion: several models, one answer](https://modeless-web.vercel.app/fusion.md): Fusion sends your request to a panel of inexpensive models in parallel and an aggregator combines their answers. Frontier-level answers at a lower price.
- [Pricing: model cost + 5%](https://modeless-web.vercel.app/pricing.md): Pay as you go, no seats or subscription. Each request on your bill shows the model behind it, its tokens and its unit price.
