kani-multimodal-core 0.0.1.dev0

Core shared libraries for multimodal Kani extensions.

kani-multimodal-core

This package contains core extensions for using Kani with multimodal language models.

Installation

kani-multimodal-core should be installed alongside the core kani install using an extra:

$ pip install "kani[multimodal]"

However, you can also explicitly specify a version and install the core package itself:

$ pip install kani-multimodal-core

Features

This package provides the core multimodal extensions that engine implementations can use -- it does not provide any engine implementations on its own.

The package adds support for:

• Images (kani.ext.multimodal_core.ImagePart)
• Audio (kani.ext.multimodal_core.AudioPart)
• Video (WIP)

When installed, these core kani engines will automatically use the multimodal parts:

• OpenAIEngine
• AnthropicEngine

Additionally, the core kani chat_in_terminal method will support attaching multimodal data from a local drive or from the internet using @/path/to/media or @https://example.com/media.

Message Parts

The main feature you need to be familiar with is the MessagePart, the core way of sending messages to the engine. To do this, when you call the kani round methods (i.e. Kani.chat_round or Kani.full_round or their str variants), pass a list of multimodal parts rather than a string:

from kani import Kani
from kani.engines.openai import OpenAIEngine
from kani.ext.multimodal_core import ImagePart

engine = OpenAIEngine(model="gpt-4.1-nano")
ai = Kani(engine)

# notice how the arg is a list of parts rather than a single str!
msg = await ai.chat_round_str([
    "Please describe this image:",
    ImagePart.from_file("path/to/image.png")
])
print(msg)

See the docs (TODO) for more information about the provided message parts.

Terminal Utility

When installed, kani-multimodal-core augments the chat_in_terminal utility provided by kani.

This utility allows you to provide multimodal media on your disk or on the internet inline by prepending it with an @ symbol:

>>> from kani import chat_in_terminal
>>> chat_in_terminal(ai)
USER: Please describe this image: @path/to/image.png and also this one: @https://example.com/image.png
