ai gpt 5.2 pro Frequently Asked Questions
Learn how to deploy the ai gpt 5.2 pro for agentic workflows and explore technical specs like reasoning effort and native video processing.
How do I migrate to the ai gpt 5.2 pro model?
Migration is straightforward as the ai gpt 5.2 pro remains backward compatible with existing OpenAI SDKs. Simply update your model string to gpt-5.2-pro-2025-12-11 in your configuration. Our platform handles the underlying routing and provides unified credits across tiers. If you are coming from gpt-4o, you will notice immediate improvements in instruction following and context retention up to the full 256k limit without changing code.
What is the pricing for ai gpt 5.2 pro tokens?
The ai gpt 5.2 pro is priced at $5.00 per 1 million input tokens and $15.00 per 1 million output tokens. To help manage costs for large ai projects, we offer a 50% discount on cached inputs, reducing the rate to $2.50 per 1M tokens. For non-urgent ai tasks, our Batch API provides an additional 50% discount for a 24-hour turnaround, making this pro model accessible for high-volume data synthesis and large-scale ai analysis.
Can this ai gpt 5.2 pro handle native video files?
Yes, the ai gpt 5.2 pro features native video understanding. It processes video files temporally rather than using frame-sampling, allowing the ai to see motion and changes over time. It supports 1080p clips up to 5 minutes in length. This makes it an ideal ai solution for tasks like analyzing security footage, performing automated video QA, or generating descriptive metadata for multimodal ai databases at scale.
What is the reasoning effort parameter in gpt 5.2?
The reasoning_effort parameter is a new setting for the ai gpt 5.2 pro that allows you to control the depth of the ai model's internal verification process. By selecting 'low', 'medium', or 'high', you determine how much computational effort the ai spends on 'Chain of Thought' steps. We recommend setting this to 'high' for complex coding and mathematical deduction to maximize the logical accuracy of the ai gpt 5.2 pro.
Is my data used to train the ai gpt 5.2 pro?
No. At GPTProto.com, privacy is a core pillar of our ai service. Any data sent to the ai gpt 5.2 pro via our API is never used to train the underlying models. We provide enterprise-grade security for all ai requests, ensuring that your proprietary code and sensitive documents remain confidential. This makes the ai gpt 5.2 pro safe for use in regulated industries like finance, healthcare, and corporate law.
How does gpt 5.2 pro score on SWE-bench?
The ai gpt 5.2 pro scores 52.4% on SWE-bench Verified. This is a significant milestone for ai, indicating the pro model can autonomously resolve over half of real-world GitHub issues. This capability allows the ai to act as a senior-level dev agent, diagnosing bugs and drafting PRs. Combined with its 256k context, the ai gpt 5.2 pro is the most capable ai for software engineering currently available on our platform.
