Ollama backend

[krzysztofjeziorny]

In the last Wagtail webinar @tomdyson mentioned that this project can use Ollama with the Llava model as a backend. Is it already possible or meant for a future release? I've been looking at the docs, but didn't find any examples.

Thanks for this interesting project!

I may try to answer myself - Ollama integration comes with llm and llm-ollama, as described under Using other models. I experienced errors, but that's for a start only :)

My test setup comes as follows:

WAGTAIL_AI = {
    "BACKENDS": {
        "default": {
            "CLASS": "wagtail_ai.ai.llm.LLMBackend",
            "CONFIG": {
                "MODEL_ID": "llama3:latest",
            },
        },
        "llava": {
            "CLASS": "wagtail_ai.ai.llm.LLMBackend",
            "CONFIG": {
                "MODEL_ID": "llava-llama3:latest",
                "TOKEN_LIMIT": 300,
            },
        },
    },
    "IMAGE_DESCRIPTION_BACKEND": "llava",
}
WAGTAILIMAGES_IMAGE_FORM_BASE = "wagtail_ai.forms.DescribeImageForm"

The image description couldn't be generated (NotImplementedError: This backend does not support image description).

The text editor gave away a longer error:

"The editor just crashed. Content has been reset to the last saved version."

At the moment the image description functionality is

This feature is experimental and is currently only supported when using OpenAI as a provider

as per the release notes https://github.com/wagtail/wagtail-ai/releases/tag/v2.1.0

Can you check if the rich text editor integration works without IMAGE_DESCRIPTION_BACKEND and WAGTAILIMAGES_IMAGE_FORM_BASE ?

[krzysztofjeziorny]

Setting just the default backend (with llama3:latest) works! Kind of: the completion prompt works, the correction one creates… also completion.

It seems the prompt takes the content of the whole text block as the input, not just the marked part, eg. a paragraph?

Crucial is to set the "TOKEN_LIMIT", otherwise the editor crashes.
