📄 Description

Currently we assume that images take 768 tokens of context size for the purposes of clipping old messages that exceed the context window. However, our mllama implementation stores the full image embedding in a single token. As a result, there is significant waste of context space.

Ideally, we would handle this more generically and have the implementation report the number of tokens. However, at the moment this would just result in a similar set of 'if' conditions in the runner plus APIs to report it back. So for now, we just keep this simple.

🔄 This issue represents a GitHub Pull Request. It cannot be merged through Gitea due to API limitations.
