Frequently asked questions
How does GPT-5.2-Codex perform overall in AI benchmarks?
GPT-5.2-Codex ranks #92 out of 230 models on the public BenchAlign leaderboard, with a score of 57.98/100. Its evidence status is Supported, and this profile shows 3 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is GPT-5.2-Codex good for coding and programming?
GPT-5.2-Codex ranks #48 out of 148 eligible models for coding and programming, with a public category score of 56.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Is GPT-5.2-Codex good for agentic tool use and computer tasks?
GPT-5.2-Codex ranks #52 out of 143 eligible models for agentic tool use and computer tasks, with a public category score of 53.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.
Does GPT-5.2-Codex have full benchmark coverage on BenchLM?
No. GPT-5.2-Codex currently has 15 source-displayable rows across 416 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of GPT-5.2-Codex?
GPT-5.2-Codex has a reported context window of 400K in the exact-model catalog record. The value stays visible, but the profile marks its source link as unavailable instead of presenting it as directly documented. Maximum output length remains separate because providers often publish a different limit.
