Ollama

The ollama provider connects to a local Ollama instance. Ollama exposes an OpenAI-compatible API, so requests are forwarded as-is.

Configuration

[providers.ollama]
kind = "ollama"
models = ["llama3.2", "mistral"]

The default base URL is http://localhost:11434/v1. Override it if Ollama runs on a different host:

[providers.ollama]
kind = "ollama"
base_url = "http://192.168.1.100:11434/v1"
models = ["llama3.2"]

No API key is needed for local Ollama.

Usage

Start Ollama, pull a model, then send requests through crabllm:

ollama pull llama3.2
crabllm --config crabllm.toml

curl http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "llama3.2",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Supported Endpoints

• Chat completions (streaming and non-streaming)
• Embeddings (if supported by the Ollama model)
