About this model

GPT-5.2 is a frontier-grade model in OpenAI's GPT-5 series, released in December 2025 and described by OpenAI as its most advanced model for everyday professional work, spanning reasoning, long-context understanding, coding, and vision. It uses adaptive reasoning to allocate computation dynamically, answering simple queries quickly while spending more depth on complex tasks, and supports a 256K-token context window alongside function-calling and web-search.

Compared with its predecessor GPT-5.1, OpenAI reports stronger multi-step reasoning, greater quantitative accuracy, and more reliable problem solving on complex technical tasks. A key theme is token efficiency: OpenAI states that despite a higher per-token price, the cost of reaching a given quality level can end up lower because GPT-5.2 uses fewer tokens, and the company highlights improved tool calling and lower latency in agentic workflows. In the API, reasoning effort is configurable from none through extra-high.

Within the GPT-5 family, GPT-5.2 has a coding-specialized counterpart in [[sibling:openai-gpt-52-codex|GPT-5.2 Codex]], which OpenAI tuned for long-horizon agentic coding, context compaction, large refactors, and Windows environments. It was later succeeded by [[sibling:openai-gpt-54|GPT-5.4]] and [[sibling:openai-gpt-55|GPT-5.5]], with OpenAI's documentation now recommending the newer GPT-5.5 for the most complex professional work and listing GPT-5.2 as a previous frontier model.

For teams, GPT-5.2 targets long-running agents, grounded assistants, and tool-heavy production workflows, building on the GPT-5 lineage with an emphasis on reliability and efficient reasoning rather than raw scale.
