Questions

GPT-4o Mini vs GPT-5.2 Pro FAQs

Is GPT-4o Mini or GPT-5.2 Pro better for coding?+

This comparison does not currently contain a protocol-matched coding benchmark for both GPT-4o 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-4o Mini or GPT-5.2 Pro?+

GPT-4o Mini is $0.075 and GPT-5.2 Pro is $21.00 per million tokens, so GPT-4o Mini is cheaper on this metric. GPT-4o Mini is $0.30 and GPT-5.2 Pro is $168.00 per million tokens, so GPT-4o Mini is cheaper on this metric.

Which has a larger context window, GPT-4o Mini or GPT-5.2 Pro?+

GPT-5.2 Pro has the larger sourced context window. GPT-4o Mini supports 128,000 and GPT-5.2 Pro supports 400,000.

Which performs better in benchmarks, GPT-4o Mini or GPT-5.2 Pro?+

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

Can GPT-4o Mini or GPT-5.2 Pro be self-hosted?+

Both models have the same recorded self-hosting status: unsupported. GPT-4o Mini is not marked open weight; GPT-5.2 Pro is not marked open weight.

Can GPT-4o Mini and GPT-5.2 Pro understand images?+

GPT-4o Mini is not documented with image input; GPT-5.2 Pro is not documented with image input. This reflects supported input modalities, not vision quality.

Which can generate longer answers, GPT-4o Mini or GPT-5.2 Pro?+

GPT-5.2 Pro has the larger sourced maximum output: GPT-4o Mini supports 16,384 and GPT-5.2 Pro supports 128,000 output tokens.

Do GPT-4o Mini and GPT-5.2 Pro support reasoning and tool use?+

GPT-4o Mini: tool calling. GPT-5.2 Pro: reasoning and tool calling. Feature support does not establish relative quality.

Which is available from more inference providers, GPT-4o Mini or GPT-5.2 Pro?+

GPT-4o Mini has 2 sourced provider routes; GPT-5.2 Pro has 2, a tie.

Which offers better value, GPT-4o 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.
