Either way, you pay for the model calls. A median coding-agent day on our gateway is 95 requests and 8.6 million tokens. The table prices every step at one model’s rate.
Both run on Standard Compute, where each step goes to the cheapest model that can do it: routine steps go to efficient open models, hard ones to frontier models such as Claude Fable 5.1 or GPT-6 Astra.
| Model | Typical day | Busy day |
|---|---|---|
| Claude Opus 5.5 | $7.34 | $59.10 |
| Claude Sonnet 5.5 | $3.67 | $29.55 |
| GPT-6 Luna | $0.23 | $2.43 |

Aider is an open-source (Apache 2.0) AI pair programming tool that works in your terminal. It can edit multiple files, understand your git history, create commits, and works with virtually any LLM via API. It earned its reputation with a practical approach to real-world coding tasks and strong benchmark scores, but development has gone quiet: the last release was 0.86.2 in February 2026 and the last commit came in May 2026.
OpenCode is an open-source (MIT) AI coding agent best known for its terminal TUI, now also shipping a desktop app and IDE extensions with OpenCode 2. It connects to 75+ LLM providers through models.dev, has LSP integration for real code understanding, and runs several sessions in parallel. The tool is free; for models you bring your own key, use OpenCode's free Zen models, pay as you go on Zen, or subscribe to its Go plan ($10/month, Go Plus $40).
