Providers¶

antcrew-engine supports every major LLM provider through a single string prefix.

Supported prefixes¶

Prefix	Provider	Example model
`openai:`	OpenAI	`openai:gpt-4o`
`anthropic:`	Anthropic	`anthropic:claude-sonnet-5`
`groq:`	Groq	`groq:llama-3.3-70b-versatile`
`gemini:`	Google Gemini	`gemini:gemini-2.0-flash`
`moonshot:`	Moonshot AI	`moonshot:moonshot-v1-8k`
`simulated:`	Built-in mock	`simulated:echo`

Switching providers¶

# GPT-4o
agent = Agent(model="openai:gpt-4o")

# Claude — same code, different model string
agent = Agent(model="anthropic:claude-sonnet-5")

# Free local mock for tests
agent = Agent(model="simulated:echo")

BYOK via the Proxy¶

When using antcrew-proxy, your keys are stored in the platform and injected at request time. Your application code never handles credentials directly:

agent = Agent(
    model="openai:gpt-4o",
    base_url="https://proxy.antcrew.org",  # proxy handles the key
)
