About GPT 5.2 Chat
GPT 5.2 Chat was released on December 11, 2025 on AI Gateway as the conversational variant of the GPT-5.2 model family. It brings GPT-5.2 generational improvements to dialogue-optimized inference, producing more natural, coherent, and contextually aware conversations than previous chat-focused models.
The model excels at maintaining context across extended conversations, adapting tone and detail level to the conversation flow, and handling complex multi-turn interactions where previous statements inform later responses. It supports the context window of 128K tokens, function calling, and multimodal input, providing the full feature set needed for sophisticated chat applications.
If you're building premium conversational products, GPT 5.2 Chat combines the GPT-5.2 generation's broad improvements with specific optimization for chat workloads.
What To Consider When Choosing a Provider
- Configuration: GPT 5.2 Chat combines GPT-5.2 generation improvements with optimization for multi-turn dialogue.
- Configuration: While base GPT-5.2 is general-purpose, this variant specifically optimizes for conversational coherence, natural turn-taking, and tone adaptation.
- Zero Data Retention: AI Gateway supports Zero Data Retention for this model via direct gateway requests (BYOK is not included). To configure this, check the documentation.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
