Does RAG not work for the Anthropic provider?

[danielytics]

Hi,

I’m trying to implement a simple RAG setup with .context() and .dynamic_context(), using the example code here: https://book.rig.rs/playbook/rag.html#using-rag-with-agents

I use OpenAI for the embedding and the vector store.

When I use OpenAI for the agent, it works.

but when I use Anthropic for the agent, none of the documents get included. Static and dynamic, neither get included.

I also implemented my own vector store index to confirm that top_n does in fact get called and return data, but it just never gets included in the context when the request is made.

Is this expected or a known issue, or am I doing it wrong?

Ah. It seems the issue isn't actually the Antrhopic provider itself, but the model I was using: MiniMax's Anthropic-compatible endpoint doesn't appear to support documents in multi-part messages: https://platform.minimax.io/docs/api-reference/text-anthropic-api#supported-parameters

messages Partial support Supports text and tool calls, no image/document input

So this has nothing to do with Rig 😅

(In case anyone else is trying to get this to work, using the OpenAI chat completions API does work)
