FAQ
What model ID should I send for openai/gpt-5.1?
Use openai/gpt-5.1 exactly as shown in the current TackleKey pricing catalog, then confirm it is still available before a larger run.
How is the openai/gpt-5.1 example cost calculated?
Each example multiplies the displayed public price per one million tokens by the sample input or output token count. It is an estimate, not a billing promise.
Is openai/gpt-5.1 the cheapest or best model?
This page does not make that claim. Compare live OpenAI and cross-provider prices, endpoint support, request success, and output quality for your workload.
