OpenAI celebrates its 10 year anniversary with the launch of GPT-5.2, featuring significant across-the-board improvements including a rare 40% price increase. GPT-5.2 shows strong performance gains in scientific reasoning, knowledge work, and economic value tasks, achieving over 70.9% human expert parity on GDPval tasks and reaching 90.5% on ARC-AGI-1 with a large efficiency gain.

Despite some mixed results in coding benchmarks and vision capabilities, GPT-5.2 is well received as a major update with extended context and tiered reasoning controls. Pricing is set at $1.75/M input and $14/M output tokens with a 90% cache discount. The update is live in ChatGPT and API, marking a significant milestone for OpenAI's LLM development.
