3. Extended Context Window

With a 400,000-token context window, GPT 5.2 can process hundreds of pages, extensive codebases, or multiple documents simultaneously while maintaining coherent understanding throughout the conversation.

4. Enhanced Vision and Multimodal Capabilities

ChatGPT-5.2 demonstrates far better understanding of charts, diagrams, and software, and can make out details in fuzzy or complex images better too.

GPT 5.2 Benchmarks: Performance That Speaks for Itself

Professional Knowledge Work (GDPval)

OpenAI’s GDPval benchmark evaluates performance across 44 occupations spanning finance, law, consulting, and more. GPT‑5.2 Thinking beats or ties top industry professionals on 70.9% of comparisons according to expert human judges.

Software Engineering Excellence

On SWE-Bench Pro—testing realistic software engineering tasks—GPT 5.2 substantially outperforms competitors while producing outputs for GDPval tasks at over 11 times the speed and less than 1% the cost of expert professionals.

Real-World Enterprise Testing

Box CEO Aaron Levie reported that GPT-5.2 performs 7 points better than GPT-5.1 on expanded reasoning tests approximating real-world knowledge work in financial services and life sciences. Complex extraction tasks dropped from 46 seconds to just 12 seconds.

How to Use GPT 5.2: Access and Availability

ChatGPT Integration

GPT 5.2 ChatGPT access is available across all subscription tiers:

• Free users: Limited GPT 5.2 access with transition to GPT 5.2 mini after limits
• Plus ($20/month): Full Thinking variant with higher quotas
• Pro ($200/month): Unlimited access to all variants including Pro mode
• Business/Enterprise: Custom deployments with admin controls

API Access for Developers

The GPT 5.2 API launched simultaneously with ChatGPT availability, offering developers immediate access through model identifiers: gpt-5.2, gpt-5.2-chat-latest (Instant), and gpt-5.2-pro.

GPT 5.2 Pricing: Value for Advanced Capabilities

GPT 5.2 API pricing reflects its enhanced capabilities:

• GPT 5.2 Thinking: 40% price increase over GPT 5.1 ($1.25/$10 per million tokens)
• GPT 5.2 Pro: $15 input/$120 output per million tokens
• ChatGPT subscription pricing remains unchanged

Despite higher per-token costs, OpenAI argues that the model’s greater token efficiency and ability to solve tasks in fewer turns make it economically viable for high-value enterprise workflows.
