Models

Klisk is compatible with multiple language model providers thanks to the LiteLLM integration.

Default model

The recommended default model is gpt-5.2 from OpenAI.

agent = define_agent(
    name="MyAgent",
    model="gpt-5.2",
    # ...
)

Supported providers

Provider	Model format	Example
OpenAI	gpt-*	gpt-5.2, gpt-4.1
Anthropic	anthropic/model	anthropic/claude-sonnet-4-20250514
Google Gemini	gemini/model	gemini/gemini-2.5-pro
Mistral	mistral/model	mistral/mistral-large-latest

To use non-OpenAI providers, install the package with LiteLLM support:

pip install 'klisk[litellm]'

And set the corresponding API key in your .env:

ANTHROPIC_API_KEY=sk-ant-...
GEMINI_API_KEY=...
MISTRAL_API_KEY=...

Temperature and reasoning effort

These parameters are passed directly to define_agent():

agent = define_agent(
    name="MyAgent",
    model="gpt-5.2",
    temperature=0.7,           # Creativity (0-1)
    reasoning_effort="medium", # Only for o-series and gpt-5+
)

WARNING

reasoning_effort is only supported by o-series models (o1, o3, o4-mini) and gpt-5+. Do not use it with gpt-4.1 or gpt-4o.

Check the other models guide for detailed configuration.
