Add GPT Image 2 model support for image generation#302
Merged
Conversation
Adds GPT_IMAGE_2 ("openai/gpt-image-2") to the TEE_LLM enum so the SDK
can route to OpenAI's image-generation model already supported by the
tee-gateway. Billed at a flat per-image rate; images returned as data:
URIs on the response. Updates the image-generation example and README
model list.

Summary
Add support for OpenAI's GPT Image 2 model via the TEE endpoint for native image generation capabilities.
Changes
src/opengradient/types.py: AddedGPT_IMAGE_2 = "openai/gpt-image-2"enum value toTEE_LLMwith documentation noting:/images/generationsendpointTextGenerationOutput.imagesandStreamChunk.imagesexamples/llm_image_generation.py: Updated example documentation to list GPT Image 2 as an available image generation model with pricing ($0.05/image)README.md: Added "GPT Image 2 (native image generation)" to the OpenAI models list in the supported models sectionImplementation Details
The model follows the existing TEE LLM pattern and integrates with the image generation infrastructure already in place. Images are handled separately from the signed output, consistent with other image generation models like Gemini variants.
