## Overview

GPT-5.2 Instant is OpenAI's fast, high-throughput model in the GPT Instant line, released on December 11, 2025 as part of the GPT-5.2 family alongside GPT-5.2 Thinking and GPT-5.2 Pro. It is the default low-latency model behind "GPT-5.2 Instant" mode in ChatGPT and is exposed in the API as gpt-5.2-chat-latest. Unlike the Thinking and Pro variants, Instant answers without extended reasoning, trading deliberation for speed on everyday tasks.

OpenAI positions GPT-5.2 Instant as the workhorse for info-seeking questions, how-tos and walkthroughs, technical writing, and translation. It accepts text and image input and returns text, with a 128,000-token context window and up to 16,384 output tokens. Its knowledge cutoff is August 31, 2025, shared across the GPT-5.2 family.

Compared with GPT-5.1 Instant, the 5.2 generation reduced hallucinations and improved general intelligence and instruction-following. Note that the published GPT-5.2 reasoning benchmarks (such as GPQA Diamond, ARC-AGI-2, SWE-bench Verified, and GDPval) are reported for the Thinking and Pro variants rather than Instant, so they are not attributed to this model here. OpenAI has since marked gpt-5.2-chat-latest as deprecated and recommends GPT-5.5 for new API work.

## Pricing

- Input: $1.75 / 1M tokens per 1M tokens
- Cached input: $0.175 / 1M tokens per 1M tokens
- Output: $14.00 / 1M tokens per 1M tokens

Cached input is discounted 90%. Pricing matches the GPT-5.2 family; gpt-5.2-chat-latest is now deprecated, with GPT-5.5 recommended for new work.
