Chat Completion

Given a list of messages comprising a conversation, return a response. Optionally include an initial `role: system` message to influence the way the LLM answers. If `use_context` is set to `true`, the model will use context coming from the ingested documents to create the response. The documents being used can be filtered using the `context_filter` and passing the document IDs to be used. Ingested documents IDs can be found using `/ingest/list` endpoint. If you want all ingested documents to be used, remove `context_filter` altogether. When using `'include_sources': true`, the API will return the source Chunks used to create the response, which come from the context provided. When using `'stream': true`, the API will return data chunks following [OpenAI's streaming model](https://platform.openai.com/docs/api-reference/chat/streaming): ``` {"id":"12345","object":"completion.chunk","created":1694268190, "model":"private-gpt","choices":[{"index":0,"delta":{"content":"Hello"}, "finish_reason":null}]} ```
