When to pick which
o3 costs $2/$8 per million against o4-mini's $1.10/$4.40, roughly 1.8x more, with the same 200K context window. Both are deliberate reasoning models that spend thinking tokens before answering. o4-mini captures a surprising share of o3's performance on maths, science, and code, making it the default for cost-conscious reasoning workloads like tutoring apps or verification passes. Reserve o3 for the hardest problems where o4-mini's failure rate is measurably higher: competition-level maths, subtle concurrency bugs, or multi-constraint planning. Note that thinking tokens are billed as output, so real costs run above headline prices for both.
