Yes. GPT Terra Latest accepts tools and tool_choice for function calling. It also supports structured outputs via a JSON schema in response_format.
Yes. OpenAI caches prompts of 1024 tokens or more automatically, and GPT Terra Latest bills a cache write on each cached prompt whether or not the cached prefix is read again. To turn caching off for a request, set prompt_cache_options.mode to "explicit" at the request root and do not mark any content block with prompt_cache_breakpoint. Explicit mode disables OpenAI-managed breakpoints, so a request with none of your own has no cacheable prefix and is billed at the plain input rate. See the prompt caching guide.
GPT Terra Latest accepts files such as PDFs, images, and text as input and returns text.
GPT-6 Luna Pro, GPT-6 Luna, GPT-6 Sol Pro and 59 more are other text models from OpenAI.
