Questions people ask
Is gpt-5 better than gpt-5.2?
gpt-5.2 outperforms gpt-5 on 9 of 9 shared benchmarks. See the benchmark comparison above for specifics — gpt-5 and gpt-5.2 have different strengths across reasoning, coding, math and multimodal tasks.
Which is cheaper — gpt-5 or gpt-5.2?
gpt-5 is cheaper. gpt-5 costs $1.25/$10.00 per 1M input/output tokens, while gpt-5.2 costs $1.75/$14.00.
Can I use gpt-5 and gpt-5.2 through the same API?
Yes. Requesty provides a single OpenAI-compatible API that routes to both. Change just the "model" parameter to switch — "openai/gpt-5" or "openai/gpt-5.2" — no other code changes needed.
What are the context windows?
gpt-5 supports up to 400K tokens of context. gpt-5.2 supports up to 400K tokens. Longer context means you can feed larger documents or codebases in a single prompt, though quality often degrades past 128K for most models.
