Message with Claude 3.5 Sonnet, Llama 3.3, Gemini, and other LLMs through Discord.
vnc-lm is a Discord bot for messaging with language models. Configure model parameters, branch conversations, and edit prompts to improve responses. It is integrated with ollama and LiteLLM.
Supported Providers
Load models using the /model command. Configure model behavior by adjusting the system_prompt (base instructions), temperature (response randomness), and num_ctx (context length) parameters.
# model loading / configuration example
/model model:command-r-plus-08-2024 system_prompt: You are a helpful assistant. temperature: 0.4The bot creates a new thread upon successful model loading and sends a confirmation notification. To switch models within a thread, use + followed by any distinctive part of the model name.
# model switching examples
# switch to claude-sonnet-3.5
+ claude, + sonnet, + 3.5
# switch to gemini-2.0-flash-exp
+ gemini, + flash, + exp
# switch to gpt-4o
+ gpt, + 4oWhen you switch models within a thread, your conversation history and settings (system_prompt and temperature) stay unchanged.
Reply branch to any message in a thread to create a new branch of the conversation. The new branch will include a link to the original thread and a conversation summary up to the point where it branched. Hop between branches while keeping separate conversation histories, letting you explore different paths with any model.
Long messages are automatically split into pages. The context window supports text files, links, and images. Images can be handled either with multi-modal models or with OCR depending on how the .env is configured. The bot can be configured to require mention or to respond without a direct mention.
Edit any prompt to refine a model's response. The bot will generate a new response using your edited prompt, replacing the previous one. Edits and deletions in Discord sync immediately with the conversation cache and update the model's context for future responses. Conversations are stored in bot_cache.json and persist across Docker container restarts with a bash script.
Download ollama models by sending a model tag link in a channel.

https://huggingface.co/bartowski/Llama-3.2-1B-Instruct-GGUF/blob/main/Llama-3.2-1B-Instruct-Q8_0.ggufLocal models can be removed with the remove parameter of /model.
# ollama model removal example
/model model:granite3-dense:8b-instruct-q8_0 remove:TrueNote
Enable model downloading and removal by adding your Discord user ID to the .env.
The num_ctx parameter for /model can only be used with ollama models.
With LiteLLM integration, a wide range of language model APIs can be accessed through a single proxy interface. Any model provider available through LiteLLM is supported.
LiteLLM includes support for OpenAI-compatible APIs. This opens up support for many popular open source local LLM services.
Add models by filling out litellm_config.yaml file in the vnc-lm/ directory. The configuration supports all providers and parameters available through LiteLLM's proxy.
LiteLLM is packaged with the bot and starts automatically when the Docker container is built. While LiteLLM integration is available, the bot can function solely with ollama.
Docker: Docker is a platform designed to help developers build, share, and run container applications. We handle the tedious setup, so you can focus on the code.

}When sending text files to a local model, be sure to set a proportional num_ctx value with /model.
Occasionally the Discord API will throw up errors in the console.
# discord api error examples
DiscordAPIError[10062]: Unknown interaction
DiscordAPIError[40060]: Interaction has already been acknowledgedThe errors usually seem to be related to clicking through pages of an embedded response. The errors are not critical and should not cause the bot to crash.
When adding a model to the litellm_config.yaml from a service that uses a local API (text-generation-webui for example), use this example:
# add openai/ prefix to route as OpenAI provider
# add api base, use host.docker.interal:{port}/v1
# api key to send your model. use a placeholder when the service doesn't use api keys
model_list:
- model_name: my-model
litellm_params:
model: openai/<your-model-name>
api_base: <model-api-base>
api_key: api-key If LiteLLM is exiting in the console log when doing docker compose up --build --no-color. Open the docker-compose.yaml and revise the following line and run docker compose up --build --no-color again to see more descriptive logs.
# original
command: -c "exec litellm --config /app/config.yaml >/dev/null 2>&1"
# revised
command: -c "exec litellm --config /app/config.yaml"Most issues will be related to the litellm_config.yaml file. Double check your model_list vs the examples shown in the LiteLLM docs. Some providers require additional litellm_params.
Cache issues are rare and difficult to reproduce but if one does occur, deleting bot_cache.json and re-building the bot should correct it.
