GPT-5.2 API: a well-tested previous-generation flagship
GPT-5.2 is OpenAI's previous-generation flagship model, delivering strong all-around performance with a 400K-token context window and up to 128K output tokens. At $2.45 per 1M input tokens and $19.60 per 1M output tokens, it is a versatile, dependable choice for general-purpose workloads.
Through YepAPI you call GPT-5.2 with a single OpenAI-compatible API key. The same key also reaches other models and YepAPI's SEO, SERP, and web-scraping endpoints, so you can build broad applications without managing multiple providers.
What is GPT-5.2?
GPT-5.2 is OpenAI's previous-generation flagship model, a general-purpose system that performs well across reasoning, writing, analysis, and code. Unlike a specialist, it is a balanced all-rounder, which makes it a safe default for mixed workloads. It carries a large 400,000-token context window and can produce up to 128,000 output tokens, so it handles long documents, extended conversations, and substantial code in a single request. As a mature, well-tested release it offers predictable behavior at $2.45 per 1M input and $19.60 per 1M output tokens — flagship-class capability below the newest generation's pricing.
Build with GPT-5.2 via YepAPI
Send requests to the OpenAI-compatible /v1/ai/chat endpoint using your YepAPI key. The standard Chat Completions schema means existing OpenAI SDKs work after changing only the base URL and model name. Use it as a general workhorse for assistants, content tools, analysis, and light coding. Because one key also unlocks other models plus SEO, SERP, and scraping APIs, you can power a whole product — from chat to data gathering — through a single integration.
GPT-5.2 API pricing — $2.45 / $19.60 per 1M tokens
GPT-5.2 costs $2.45 per 1M input tokens and $19.60 per 1M output tokens. As a previous-generation flagship, it gives broad, high-quality capability at a price below the current line, which suits varied production workloads. With a 400K context you can feed large inputs affordably, and per-token billing means you pay only for what each request actually uses.
GPT-5.2 for general-purpose applications
The model fits products that need one capable model across many tasks: a single backend handling chat, summarization, drafting, analysis, and occasional code. Its 400K context and 128K output cover both long-input and long-output needs, while its tested reliability keeps behavior stable as you scale. When you want a balanced, proven flagship rather than a narrow specialist, GPT-5.2 is a strong default.
