Questions
GPT-5 Mini vs GPT-5.2 Pro FAQs
Is GPT-5 Mini or GPT-5.2 Pro better for coding?+
This comparison does not currently contain a protocol-matched coding benchmark for both GPT-5 Mini and GPT-5.2 Pro, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.
Which is cheaper, GPT-5 Mini or GPT-5.2 Pro?+
GPT-5 Mini is $0.125 and GPT-5.2 Pro is $21.00 per million tokens, so GPT-5 Mini is cheaper on this metric. GPT-5 Mini is $1.00 and GPT-5.2 Pro is $168.00 per million tokens, so GPT-5 Mini is cheaper on this metric.
Which has a larger context window, GPT-5 Mini or GPT-5.2 Pro?+
Neither model has a larger sourced context window in this comparison. GPT-5 Mini is 400,000 and GPT-5.2 Pro is 400,000.
Which performs better in benchmarks, GPT-5 Mini or GPT-5.2 Pro?+
There is no overall benchmark winner: An overall winner requires at least two decisive benchmarks from at least two original publishers.
Can GPT-5 Mini or GPT-5.2 Pro be self-hosted?+
Both models have the same recorded self-hosting status: unsupported. GPT-5 Mini is not marked open weight; GPT-5.2 Pro is not marked open weight.
Can GPT-5 Mini and GPT-5.2 Pro understand images?+
GPT-5 Mini is documented with image input; GPT-5.2 Pro is documented with image input. This reflects supported input modalities, not vision quality.
Which can generate longer answers, GPT-5 Mini or GPT-5.2 Pro?+
Neither has a larger sourced maximum output. GPT-5 Mini is 128,000 and GPT-5.2 Pro is 128,000.
Do GPT-5 Mini and GPT-5.2 Pro support reasoning and tool use?+
GPT-5 Mini: reasoning, tool calling, and image input. GPT-5.2 Pro: reasoning, tool calling, and image input. Feature support does not establish relative quality.
Which is available from more inference providers, GPT-5 Mini or GPT-5.2 Pro?+
GPT-5 Mini has 2 sourced provider routes; GPT-5.2 Pro has 2, a tie.
Which offers better value, GPT-5 Mini or GPT-5.2 Pro?+
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.
