o3 vs o3-pro

This comparison does not currently contain a protocol-matched coding benchmark for both o3 and o3-pro, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.

o3 is $1.00 and o3-pro is $20.00 per million tokens, so o3 is cheaper on this metric. o3 is $4.00 and o3-pro is $80.00 per million tokens, so o3 is cheaper on this metric.

Neither model has a larger sourced context window in this comparison. o3 is 200,000 and o3-pro is 200,000.

There is no overall benchmark winner: At least two independently verified, protocol-matched benchmarks are required for an overall winner.

Both models have the same recorded self-hosting status: unsupported. o3 is not marked open weight; o3-pro is not marked open weight.

o3 is documented with image input; o3-pro is documented with image input. This reflects supported input modalities, not vision quality.

Neither has a larger sourced maximum output. o3 is 100,000 and o3-pro is 100,000.

o3: reasoning, tool calling, and image input. o3-pro: reasoning, tool calling, and image input. Feature support does not establish relative quality.

o3 has 2 sourced provider routes; o3-pro has 2, a tie.

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
