GPT-6 Luna is the fast, cost-efficient tier of the GPT-6 series on the Felo API, at $0.10 per million input tokens. Here is what that buys across classification, extraction, chat, and subagent workloads.

GPT-6 Sol sits between the Astra flagship and the Luna fast tier at $2 per million input tokens. Here is the arithmetic of the middle rung, and the routing pattern that gets flagship outcomes without flagship spend.

Claude Opus 5.5 is now on the Felo API with a 1M-token context window, cached input rates, and an Anthropic-compatible Messages endpoint. Here is what caching actually does to the cost of a long-running agent.

Grok 4.7 is live on the Felo API with a 450,000-token maximum output — three and a half times the frontier norm. Here is what that ceiling changes for coding agents, self-verifying loops, and whole-package migrations.

GPT-6 Sol is live in Felo Search: 1.05M context at $2/$10 per million tokens, the mid-tier built for the agent loops AI search depends on.
