GPT-5.2 (OpenAI)

GPT-5.2 is OpenAI's December 2025 flagship release, positioned by the company as a step forward in agentic AI workflows where models plan, use tools, and carry out multi-step tasks on behalf of users. Reporting around launch framed it as OpenAI's latest move in the competitive agentic AI race, with OpenAI claiming the model hallucinates less and is more accurate than its predecessor. That emphasis on reliability and grounded reasoning is the central story of the release, signaling OpenAI's focus on practical, task-completing behavior rather than purely conversational polish.

The most concrete measure of GPT-5.2's capabilities comes from abstract-reasoning benchmarks, where it reportedly achieved roughly 53–54% on ARC-AGI-2, a substantial leap over earlier OpenAI models that scored near zero on the same test. That result positioned GPT-5.2 as a meaningful advance in tackling novel, pattern-based problems that resist memorization, a useful proxy for the kind of adaptive thinking agentic applications demand. In practice, GPT-5.2 fits workflows that benefit from deeper reasoning over long, multimodal inputs and structured tool use, while the broader competitive landscape continues to evolve quickly around it.
