About GPT-5.2 latest
GPT-5.2 is OpenAI's December 2025 frontier model built for professional and enterprise knowledge work, accessed here via the "gpt-5.2-chat-latest" dated checkpoint alias. Where its predecessor stumbled on complex multi-step tasks, GPT-5.2 doubled the GDPval knowledge work score — from 38.8% to 70.9% — and hit a 1.1% hallucination rate that makes it unusually dependable for high-stakes documents, client reports, and business decisions. Its 400,000-token context window means entire codebases or research libraries can be ingested in one session. Developers in particular value the deliberate reasoning in Thinking mode: thorough tool calls, strong context retention, and a SWE-Bench Pro score of 55.6% that reflects genuine software engineering ability, not just toy benchmarks. Be honest about the trade-offs though: reasoning mode carries a latency cost that can feel slow in interactive use, and early users who preferred the personality of GPT-4o found GPT-5.2's tone more sanitized. It earns its place for structured output, precision work, and agentic pipelines — less so for freeform creative conversation.
Best for
- Complex code review, refactoring, and agentic software engineering workflows
- Long-document analysis — contracts, research papers, or entire repositories up to 400k tokens
- Professional knowledge work: reports, presentations, business intelligence, and high-accuracy deliverables
- Graduate-level math and science problem-solving (100% on AIME 2025, 92%+ on GPQA Diamond)
- Multi-step agentic automation requiring reliable tool use and function calling

Frequently asked questions
What is gpt-5.2-chat-latest, and is it different from the base GPT-5.2 model?
It is a dated checkpoint alias pointing to the base GPT-5.2 model family released December 11, 2025. The underlying model is the same; the alias simply pins you to that specific release rather than a moving latest pointer.
How much does GPT-5.2 cost?
$1.75 per million input tokens and $14.00 per million output tokens. Cached input tokens get a 90% discount ($0.175/M), making repeated long-context work significantly cheaper. It runs roughly 40% more expensive per token than GPT-5.1, though fewer required steps per task can offset the premium.
What is the context window and max output?
GPT-5.2 accepts up to 400,000 input tokens and can produce up to 128,000 output tokens — enough to ingest large codebases or lengthy document sets in a single session.
Is the reasoning mode fast enough for interactive use?
The Thinking variant's time to first token can exceed two minutes due to internal reasoning computation. For interactive or latency-sensitive tasks, the Instant variant is the better choice. Azure deployments also add a further 4-5x latency penalty compared to OpenAI's direct API.
Who should pick GPT-5.2 over GPT-5.1?
GPT-5.2 is the stronger choice for complex coding, long-document analysis, scientific reasoning, and agentic pipelines where accuracy matters more than response speed or personality. Users who primarily want conversational depth or creative writing may not find the upgrade compelling, as some found its tone more corporate than its predecessor.
Does it support images and what else can it output?
GPT-5.2 accepts text and images as input and produces text output. It does not natively generate images or audio.
