Durable execution of Pydantic AI agents on Postgres via Absurd.

Pydantic AI Absurd

Durable execution for Pydantic AI agents, on Postgres alone.

---

Agents run for a while - a model call, a tool call, another model call. When the worker dies in the middle of that, the run is usually lost: you restart from zero and pay for every token again.

Pydantic AI Absurd fixes that. Call agent.run() inside a durable task and every model and MCP call is checkpointed into Postgres. If the worker crashes, a new one resumes from the last completed step - no restart, no re-spent tokens. Same idea as Pydantic AI's Temporal integration, but with no Temporal, no Redis, no broker: just the Postgres you already have.

Installation

pip install pydantic-ai-absurd

Example

from absurd_sdk import AsyncAbsurd
from pydantic_ai import Agent
from pydantic_ai_absurd import AbsurdAgent

absurd = AsyncAbsurd("postgresql://localhost/absurd", queue_name="agents")
agent = AbsurdAgent(Agent("openai:gpt-5.2", name="analyst"), absurd)

@absurd.register_task(name="analyse")
async def analyse(params, ctx):
    result = await agent.run(params["prompt"])
    return {"output": result.output}

await absurd.spawn("analyse", {"prompt": "Analyse Q3 revenue"})
await absurd.work_batch(batch_size=1)

You author a task, call the agent inside it, and run it durably. That's the whole idea.
