OpenAI has officially launched GPT-5.2, and the preliminary results confirm it’s not just an iteration—it’s a massive leap forward. Backed by extensive new benchmarks and stunning demos, GPT-5.2 is setting new standards for thinking, coding, and real-world utility. This is a breakdown of the key areas where the model is dominating the competition.
State-of-the-Art Benchmarks and AGI Progress
GPT-5.2 didn’t just inch ahead; it claimed the top spot in almost every major intelligence benchmark, signaling a major advance towards AGI:
- Logic and Reasoning: The model achieved State-of-the-Art (SOTA) status on both Swebench Pro (coding) and GPQA Diamond (science reasoning) [01:05, 01:23].
- Perfect Math: GPT-5.2 aced (100%) the rigorous Amy 2025 math competition, surpassing its competitors [01:34].
- The AGI Leap: The most stunning result is on the ARC AGI 2 benchmark, which tests the model’s ability to learn and generalize. GPT-5.2’s score jumped from 17% (5.1) to 52.9% (5.2), placing it far ahead of other frontier models [01:52].
- Massive Efficiency Gains: The cost for running high-level models on complex tasks has seen a staggering 390x efficiency improvement over the last year, with a task that once cost $4,500 now costing just $11 [03:04].
Trustworthy for High-Stakes Economic Work
A primary focus for GPT-5.2 is its ability to handle “economically valuable tasks,” where accuracy is paramount. The model demonstrates significant improvements in data integrity and professional output:
- Financial Accuracy: In cap table management (a complex financial spreadsheet), GPT-5.1 was shown to incorrectly calculate liquidation preferences [06:14]. GPT-5.2, however, got it all right, providing a much more trustworthy foundation for high-stakes business calculations [06:57].
- Professional Output: It excels at generating professional documents, like a workforce planner or a project report, with superior formatting that is easily readable and organized, unlike the basic output from 5.1 [05:50, 07:22].
Incredible Coding and Tool-Use Capabilities
The model’s coding and multimodal skills are highly impressive, especially in complex, dynamic tasks:
- Dynamic UI Coding Demo: One of the most impressive feats is GPT-5.2’s ability to generate a single-page HTML app for an ocean wave simulation [07:52]. This realistic, animated wave display includes a functional user interface to change parameters like wind speed, wave height, and lighting, all from a single prompt [08:22].
- Visual Reasoning: Error rates in visual reasoning—like understanding charts, scientific figures, and software interfaces (GUIs)—have been cut roughly in half [09:57, 10:49].
- Complex Tool Calling: The model is dramatically better at managing long chains of tool calls (plugins), jumping from 47% to nearly 98.7% accuracy on a telecom customer support benchmark [11:36].
Availability and Price
GPT-5.2 is available immediately for paid users across its Instant, Thinking, and Pro versions [05:19]. However, this power comes at a cost; the pricing for the model is higher than GPT-5.1 (e.g., input tokens increased from $1.25 to $1.75 per million) [12:33]. Despite the increased cost, the significant jump in performance and reliability makes the investment worthwhile for professional use cases.
