What is SSE streaming in AI APIs?

SSE (Server-Sent Events) streaming lets AI APIs send tokens progressively. Each chunk is a data: line containing JSON with a delta or content field.

Which streaming formats are supported?

OpenAI (choices[0].delta.content), Anthropic Claude (delta.text / content_block_delta), and Google Gemini (candidates[0].content.parts[0].text) are all parsed.

Is my stream data sent anywhere?

No. All parsing happens locally in your browser.
