Providers

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

You can find our model recommendations on the Evals page.

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

gptme "hello" -m openai/gpt-5
gptme "hello" -m anthropic  # will use provider default
gptme "hello" -m openrouter/x-ai/grok-4
gptme "hello" -m deepseek/deepseek-reasoner
gptme "hello" -m gemini/gemini-2.5-flash
gptme "hello" -m groq/llama-3.3-70b-versatile
gptme "hello" -m xai/grok-beta
gptme "hello" -m local/llama3.2:1b

You can list the models known to gptme using gptme '/models' - '/exit'

On first startup API key will be prompted for if no model and no API keys are set in the config/environment. The key will be saved in the configuration file, the provider will be inferred, and its default model used.

Use the [env] section in the Global config file to store API keys using the same format as the environment variables:

• OPENAI_API_KEY="your-api-key"

• ANTHROPIC_API_KEY="your-api-key"

• OPENROUTER_API_KEY="your-api-key"

• GEMINI_API_KEY="your-api-key"

• XAI_API_KEY="your-api-key"

• GROQ_API_KEY="your-api-key"

• DEEPSEEK_API_KEY="your-api-key"

Local

You can use local LLM models using any OpenAI API-compatible server.

To achieve that with ollama, install it then run:

ollama pull llama3.2:1b
ollama serve
OPENAI_BASE_URL="http://127.0.0.1:11434/v1" gptme 'hello' -m local/llama3.2:1b

Note

Small models won’t work well with tools, severely limiting the usefulness of gptme. You can find an overview of how different models perform on the Evals page.
