Questions
GPT-4o vs GPT-5.2 FAQs
Is GPT-4o or GPT-5.2 better for coding?+
This comparison does not currently contain a protocol-matched coding benchmark for both GPT-4o and GPT-5.2, so Model Markets cannot name a coding leader from pricing, context size, or capability labels alone.
Which is cheaper, GPT-4o or GPT-5.2?+
GPT-4o is $1.25 and GPT-5.2 is $1.75 per million tokens, so GPT-4o is cheaper on this metric. GPT-4o is $5.00 and GPT-5.2 is $14.00 per million tokens, so GPT-4o is cheaper on this metric.
Which has a larger context window, GPT-4o or GPT-5.2?+
GPT-5.2 has the larger sourced context window. GPT-4o supports 128,000 tokens and GPT-5.2 supports 400,000 tokens.
Which performs better in benchmarks, GPT-4o or GPT-5.2?+
There is no overall benchmark winner: An overall winner requires at least two decisive benchmarks from at least two original publishers.
Can GPT-4o or GPT-5.2 be self-hosted?+
Both models have the same sourced self-hosting status: unsupported. GPT-4o is not marked open weight; GPT-5.2 is not marked open weight.
Can GPT-4o and GPT-5.2 understand images?+
GPT-4o is documented with image input; GPT-5.2 is documented with image input. This reflects supported input modalities, not vision quality.
Which can generate longer answers, GPT-4o or GPT-5.2?+
GPT-5.2 has the larger sourced maximum output. GPT-4o supports 16,384 tokens and GPT-5.2 supports 128,000 tokens.
Do GPT-4o and GPT-5.2 support reasoning and tool use?+
GPT-4o: tool calling and image input. GPT-5.2: reasoning, tool calling, and image input. Feature support does not establish relative quality.
Which is available from more inference providers, GPT-4o or GPT-5.2?+
GPT-4o has 2 sourced provider routes; GPT-5.2 has 2, a tie.
Which offers better value, GPT-4o or GPT-5.2?+
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.
