What is GPT-5.2 Chat?

GPT-5.2 Chat is OpenAI's previous-generation, chat-optimized model, tuned specifically for conversational tasks rather than long analytical work. It favors natural, well-paced dialogue and fast responses, which makes it a good fit for assistants and support bots. It carries a 128,000-token context window and up to 16,384 output tokens per response, enough to maintain long multi-turn threads alongside knowledge-base context. As a mature release it offers reliable, predictable behavior at $2.45 per 1M input and $19.60 per 1M output tokens, giving teams a steady conversational model below the newest tier.

Build with GPT-5.2 Chat via YepAPI

Call the OpenAI-compatible /v1/ai/chat endpoint with your YepAPI key. The standard Chat Completions schema lets you integrate it with existing SDKs by changing only the base URL and model name. Use it for customer-support chat, in-product assistants, and any feature where low latency and natural dialogue matter. One key also unlocks other models plus SEO, SERP, and scraping APIs, so a single integration can power conversation and live data retrieval together.

GPT-5.2 Chat API pricing — $2.45 / $19.60 per 1M tokens

GPT-5.2 Chat costs $2.45 per 1M input tokens and $19.60 per 1M output tokens. Built for dialogue, it typically produces shorter, focused replies, which keeps per-conversation costs modest. As a previous-generation model it delivers reliable chat quality below the current pricing tier, and per-token billing means you pay only for the conversation you generate.

GPT-5.2 Chat for customer-support chatbots

The model is well suited to support and assistant scenarios: answering customer questions, following tone and escalation rules, and holding context across a session. Its 128K window keeps long conversations and policy documents in view, and its low latency keeps interactions feeling responsive. When you need a tested, fast conversational model for production chat rather than heavy reasoning, GPT-5.2 Chat fits well.
