Providers#

We support several LLM providers, including OpenAI, Anthropic, Azure, and any OpenAI-compatible server (e.g. ollama, llama-cpp-python).

To select a provider and model, run gptme with the --model flag set to <provider>/<model>, for example:

gptme --model openai/gpt-4o "hello"
gptme --model anthropic "hello"  # if model part unspecified, will fall back to the provider default
gptme --model openrouter/meta-llama/llama-3.1-70b-instruct "hello"
gptme --model local/ollama "hello"

On first startup, if --model is not set, and no API keys are set in the config or environment it will be prompted for. It will then auto-detect the provider, and save the key in the configuration file.

OpenAI#

To use OpenAI, set your API key:

export OPENAI_API_KEY="your-api-key"

Anthropic#

To use Anthropic, set your API key:

export ANTHROPIC_API_KEY="your-api-key"

OpenRouter#

To use OpenRouter, set your API key:

export OPENROUTER_API_KEY="your-api-key"

Local#

There are several ways to run local LLM models in a way that exposes a OpenAI API-compatible server, here we will cover:

ollama + litellm#

Here’s how to use ollama, with the litellm proxy to provide the API-compatible server.

You first need to install ollama and litellm.

ollama pull mistral
ollama serve
litellm --model ollama/mistral
export OPENAI_API_BASE="http://localhost:8000"
