Use other models (LiteLLM)

Klisk supports any language model provider thanks to LiteLLM.

Installation

pip install 'klisk[litellm]'

Configuration

Anthropic (Claude)

# .env
ANTHROPIC_API_KEY=sk-ant-...

agent = define_agent(
    name="MyAgent",
    instructions="...",
    model="anthropic/claude-sonnet-4-20250514",
    tools=get_tools("my_tool"),
)

Google Gemini

# .env
GEMINI_API_KEY=...

agent = define_agent(
    name="MyAgent",
    instructions="...",
    model="gemini/gemini-2.5-pro",
    tools=get_tools("my_tool"),
)

Mistral

# .env
MISTRAL_API_KEY=...

agent = define_agent(
    name="MyAgent",
    instructions="...",
    model="mistral/mistral-large-latest",
    tools=get_tools("my_tool"),
)

Model format

The format is always provider/model-name:

Provider	Prefix	Example
OpenAI	(no prefix)	gpt-5.2
Anthropic	anthropic/	anthropic/claude-sonnet-4-20250514
Google	gemini/	gemini/gemini-2.5-pro
Mistral	mistral/	mistral/mistral-large-latest

TIP

For OpenAI models you don't need a prefix or LiteLLM. Only install klisk[litellm] if you're going to use other providers.
