Features & Capabilities

What model families are supported?

123API supports mainstream text, image, video and audio model families exposed through one gateway.

Does 123API support OpenAI-compatible requests?

Yes. Chat completions and other common request styles are designed to work with OpenAI-style SDKs and payloads.

Does it support streaming?

Yes. Streaming behavior depends on the endpoint and model family you use, but chat-oriented interfaces support streaming-compatible workflows.

Are image and video APIs synchronous?

These workflows are typically asynchronous. You submit a task and then query task status to retrieve results.

Can I upload files first and reuse them later?

Yes. Use the upload endpoints where required by image and video workflows, then pass the returned URL into generation requests.

For the smoothest migration path, start with the general chat endpoint and then add image, video or audio workflows one by one.
