Show HN: Kybernis – Prevent AI agents from executing the same action twice

Hacker News - Thu, 03/05/2026 - 3:43pm

AI agents increasingly execute real system actions: issuing refunds, modifying databases, deploying infrastructure, calling external APIs.

Because agents retry steps, re-plan tasks, and run asynchronously, the same action can sometimes execute more than once.

In production systems this can cause duplicate payouts, repeated mutations, or inconsistent state.

Kybernis is a reliability layer that sits at the execution boundary of agent systems.

When an agent calls a tool:

1. execution intent is captured 2. the action is recorded in an execution ledger 3. idempotency guarantees are attached 4. the mutation commits exactly once

Retries become safe.

Kybernis is framework-neutral and works with agent frameworks like LangGraph, AutoGen, CrewAI, or custom systems.

I built this after repeatedly seeing reliability failures when AI agents interacted with production APIs.

Would love feedback from anyone building agent systems.

Show HN: LLM Price to Performance Tool

Hacker News - Thu, 03/05/2026 - 1:45pm

tldr: We launched https://vantage.sh/models - a price to performance comparison tool for LLMs. If you're familiar with ec2instances.info....this is basically the LLM version of that.

- - - -

I'm Co-Founder and CEO of Vantage posting on behalf of our team that shipped this. Vantage is a cloud cost management platform. We also maintain https://ec2instances.info/ after buying the site a few years back. We've been hearing rumblings from the community looking for something similar for LLMs...so we built it.

The site is free and open-source and provides a centralized view of LLM model specifications, pricing, benchmarks, and hosting information. We're shipping early and looking for feedback. Give it a peek and let us know what you think.
