o3-mini
LegacyStandardCost-efficient reasoning model for STEM tasks.
Excels at science, mathematics, and coding with configurable reasoning effort. Predecessor to o4-mini.
▼
o3-mini is somewhat expensive at $1.10/M tokens input and $4.40/M tokens output. Cached input reads are priced at $0.55/M tokens, making repeated context cheaper. The model supports extended reasoning, a 200K context window.
