Based on our open-source agent-pod project. - ## Private and self-hosted models Open-weight models served with vLLM or llama.cpp on your own or in-country infrastructure, monitored, and with documented failure behaviour, for data that should stay under your control. - ## Reliability and security reviews We measure how your model or agent setup behaves when things go wrong: timeouts, lost nodes, recovery cost and gaps in isolation. You get measured findings, not a checklist. - ## Language models in your product Summaries, extraction, classification and assistants built on the major model APIs, added to the web and mobile apps you already run. - ## Proof-of-concept sprints A short experiment with success criteria agreed before we start, and a straight go or no-go at the end. A negative result is still a useful result. // Research ## We publish what we test. Our AI work is backed by open experiments with predictions written before measuring, and results reported even when they are negative. - [github.comagent-pod Runs Claude Code in a hardened rootless Podman container, with a script that verifies the isolation on your own machine and a published threat model.](https://github.com/thenaithan/agent-sandbox-podman) - [github.comDistributed inference recovery What a single node failure costs an in-flight request on exo, vLLM and llama.cpp, measured across 107 trials.](https://github.com/thenaithan/distributed-inference-recovery) - [github.comDistributed inference resilience A simulation of pipeline-parallel model serving under node churn, calibrated against the Petals paper.](https://github.com/thenaithan/distributed-inference-resilience) - [naithanweigh.comAnatomy of an asymmetric persistence mechanism An essay on why cleaning up a compromised system starts with its anchor, and what that means for AI models that could persist across many devices.](https://naithanweigh.com/writing/asymmetric-persistence/) > Persistence is an asymmetry problem: the defender has to find everything, while the attacker only has to leave one thing behind. *Naithan Weigh, Anatomy of an Asymmetric Persistence Mechanism* // Related work ## Related work [All work](https://www.webfluentia.com/portfolio) [AI · Holy Oracle

RizqX came to us with a web platform built in Plasmic that they wanted to keep. We integrated with it, took over their development and release pipeline, built their Flutter app for iOS and Android, and a year later moved them off Plasmic altogether.](https://www.webfluentia.com/portfolio/rizqx) // Questions ## Questions
Will our data be used to train someone else's model? We configure providers' business and zero-retention options where they exist. When data cannot leave your infrastructure at all, we host the model for you instead.
Where do we start? With a call about the problem you want AI to solve. If a proof of concept makes sense, we scope it in writing, including what success looks like, before any work begins.
Is it safe to let AI agents write our code? It can be, with isolation, review and limited access. That is exactly what our agent setups are built around: the agent never gets production credentials and every change is reviewed by a person.
