I’m using Hatz AI as a provider in OpenCode through the OpenAI-compatible Responses API at https://ai.hatz.ai/v1/openai , and while normal text requests work, screenshots and image attachments do not. I’m trying to use Hatz the same way other OpenAI-compatible providers support multimodal conversations in OpenCode, especially for workflows like UI debugging, design review, and bug reports with visual context. From the current docs, the OpenAI Responses route appears to only document input_text usage, and I could not find documented support for image inputs such as input_image, image URLs, or file attachment handling on /v1/openai/responses. At the same time, the Hatz-native chat/completions docs do mention vision-capable models and uploaded files via file_uuids, which makes it seem like image support may only exist on the native chat route and not the OpenAI-compatible route that OpenCode depends on. I’d love to see full screenshot/image support added to the OpenAI-compatible Responses API, including support for OpenAI-style multimodal payloads, clear documentation showing the expected request format, and guidance on which models support vision through this endpoint. This would make Hatz much more usable as a drop-in OpenAI-compatible provider for OpenCode and similar clients.
