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.
Cursor is a fork of VS Code redesigned from the ground up for AI-powered development. It features tab completions, natural language code editing, codebase-wide chat, and multi-file editing. Its deep editor integration makes it one of the most polished AI coding tools available.
