FAQs for openai gpt 5.2 pro
How does openai gpt 5.2 pro differ from GPT-4o?
openai gpt 5.2 pro is a reasoning-heavy model that utilizes systematic internal verification. While GPT-4o is optimized for speed and low-latency chat, the openai gpt 5.2 pro version focuses on complex logic, achieving 40% fewer hallucinations and a 256k context window for multi-step planning and deep technical analysis.
What is the context window for gpt 5.2 pro?
The openai gpt 5.2 pro model supports a 256,000-token context window. This allows the model to process thousands of pages of documentation, full codebases, or long video transcripts in a single prompt without losing instruction adherence, which remains above 95% even as the window fills.
Does openai gpt 5.2 pro support video input?
Yes, openai gpt 5.2 pro features native video understanding. It processes video temporally at 1080p, identifying motion-based cues and dependencies in clips up to 5 minutes long. This makes openai gpt 5.2 pro superior to models that rely on simple frame-sampling for visual tasks.
What is the pricing for openai gpt 5.2 pro?
Input tokens for openai gpt 5.2 pro cost $5.00 per 1M, while output tokens are $15.00 per 1M. GPTProto also supports cached inputs at a 50% discount ($2.50 per 1M), making repetitive context tasks much more affordable when using openai gpt 5.2 pro for agentic loops.
Is openai gpt 5.2 pro better at coding?
With a 52.4% score on SWE-bench Verified, openai gpt 5.2 pro is a premier choice for autonomous software engineering. It handles graduate-level calculus and linear algebra with high precision, making openai gpt 5.2 pro a significant upgrade for technical R&D.
How do I migrate to openai gpt 5.2 pro?
The openai gpt 5.2 pro API is 100% backward compatible with existing OpenAI SDKs. Simply update your model string to 'gpt 5.2 pro 2025.12.11' in your completion calls. You can also adjust the new 'reasoning_effort' parameter to low, medium, or high.
