LLM models¶
hai supports models from OpenAI, Anthropic, DeepSeek, Google, xAI, and
Ollama.
Default model¶
The default model is the active model when a new instance of hai is launched.
Select a default model with:
/ai-default <model>
This writes to your hai.toml config which
can also be changed manually:
default_ai_model = "gpt-4.1"
If a default model isn't set, it's automatically chosen based on API key availability.
Switching models¶
Switching is as easy as:
/ai <model>
Models can even be switched mid-conversation as long as the target model supports all the capabilities (images, tools) utilized in the conversation.
