OpenAI released GPT 5.2 on December 11, 2025 and they position it as their most capable model series yet for professional knowledge work and long running agents. OpenAI If you build AI agents, automations, dashboards, or internal tools, here is why GPT 5.2 is worth paying attention to • Built to unlock more economic value, OpenAI says GPT 5.2 is better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long contexts, using tools, and handling complex multi step projects OpenAI • OpenAI reports the average ChatGPT Enterprise user already saves 40 to 60 minutes a day, and heavy users save more than 10 hours a week, with GPT 5.2 designed to push that further OpenAI • New benchmark lead on GDPval, a knowledge work evaluation across 44 occupations • GPT 5.2 Thinking beats or ties industry professionals on 70.9 percent of comparisons • It is also described as their first model that performs at or above a human expert level on this eval OpenAI • Stronger coding performance for real world engineering • 55.6 percent on SWE Bench Pro • 80.0 percent on SWE bench Verified OpenAI • More dependable factuality • OpenAI says response level errors were 30 percent relatively less common versus GPT 5.1 Thinking on a set of de identified ChatGPT queries, with a reminder to still double check anything critical OpenAI • Available as three options in ChatGPT • Instant for fast everyday work • Thinking for deeper professional tasks • Pro for the hardest questions where quality is worth the wait OpenAI • For builders using the API • Model names include gpt 5.2, gpt 5.2 chat latest, and gpt 5.2 pro • Pricing listed as 1.75 per 1M input tokens and 14 per 1M output tokens for gpt 5.2, with a 90 percent discount on cached inputs OpenAI If you are running long workflows where the agent must plan, call tools, and stay consistent across many steps, GPT 5.2 is clearly aimed at that exact production use case.
