Choosing an AI API for coding
There is no permanently best coding model; rankings shift with every release and public benchmarks rarely look like your codebase. This page shows the active models in our catalog and a way to test them on your own code.
Side-by-side pricing comparison
Active pay-as-you-go rates from our pricing catalog, sourced from each provider's official page. The catalog may lag new launches. Use the category filter to narrow the list.
Catalog rates are a single pricing snapshot, not a full tier schedule. This table does not select rates by prompt length; long prompts may cost more and change the ranking. Use the API cost calculator for supported Haiku 5.5 and xAI prompt tiers. Announced Google increases are not applied before their effective date.
Prices are per 1M tokens (standard pay-as-you-go). Always verify with your provider before budgeting.
Full comparison toolHow to evaluate a model for coding
Code is one of the few outputs you can check automatically. Use that.
- 01Cost per passing change
Give each model 20 small real tasks from your repo with tests. Count how many produce code that passes on the first or second try. Divide total spend by passes.
- 02Context is the hidden cost
Coding prompts carry files, diffs, and history. Measure your typical input size with the token estimator; input tokens usually dominate the bill, and cached-input pricing can matter a lot.
- 03Count review time
Note minutes spent fixing or reading each output. A model that is slightly pricier but needs less review is often cheaper per merged change.
- 04Check agent loop length
If you use an agent that calls tools repeatedly, one task can be many API calls. Log calls per task before projecting a monthly cost.
