PydanticAI - RedPill AI

PydanticAI exposes an OpenAI-compatible provider directly. Use OpenAIChatModel for RedPill’s Chat Completions endpoint.

Install

pip install pydantic-ai
export REDPILL_AI_API_KEY="YOUR_API_KEY"

Build an agent

import os

from pydantic_ai import Agent
from pydantic_ai.models.openai import OpenAIChatModel
from pydantic_ai.providers.openai import OpenAIProvider
from pydantic_ai.usage import UsageLimits


model = OpenAIChatModel(
    "z-ai/glm-5.2",
    provider=OpenAIProvider(
        base_url="https://api.redpill.ai/v1",
        api_key=os.environ["REDPILL_AI_API_KEY"],
    ),
)

agent = Agent(model, system_prompt="Be concise and state uncertainty.")


@agent.tool_plain
def deployment_status(service: str) -> str:
    """Return a sample deployment status."""
    return f"{service}: healthy"


result = agent.run_sync(
    "Check the gateway deployment status.",
    usage_limits=UsageLimits(request_limit=3, tool_calls_limit=1),
)
print(result.output)

Production checks

Keep explicit UsageLimits, add a network timeout, and validate tool arguments at the application boundary. For confidential-only calls, use https://tee.redpill.ai/v1 with an is_tee: true model.

Troubleshooting

Symptom	Check
Provider initialization fails	Use `OpenAIProvider` with the `/v1` base URL.
Tool calls exceed expectations	Lower `request_limit` and `tool_calls_limit`.
Model cannot call tools	Select a model that declares `tools` in the live catalog.
