API pricing

InputWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it.
$0.25
Cached inputA reduced rate for text you send over and over. If every request starts with the same instructions or the same document, the provider keeps a copy ready and charges less to read it again.
$0.025
OutputWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one.
$2.00

Benchmarks

ProgramBenchProgram reconstruction — The AI receives a working program and its documentation, then builds a replacement from scratch without the original source code, internet access or decompilation. The score is the percentage of 200 programs that pass every behavioral test. We record each model's best published mini-SWE-agent result, including higher reasoning efforts where available. Partial test-pass rates and almost-solved programs do not count toward this score. Equal scores share a rank here; the official board also uses partial progress to break ties. Higher is better.via ProgramBench
