Built With Hermes·Open model agentsFrom an Open-Model Prototype to a Production Agent
Hermes gives you control that closed models do not: your own weights, your own behaviour, no vendor lock-in. That control comes with responsibility. Serving the model, securing its tools, evaluating its output and owning it in production is the work that turns a prototype into a system.
- Stays up under real demand
- Its answers get checked, not blindly trusted
- It's yours to run and improve
Hermes. Hermes is an open model family teams build agents and assistants on when they want control over weights and behaviour.
Vibe Coding Gets You 80%. The Last 20% Is the Product
A Hermes agent that answers well in a notebook is the exciting 80%. The 20% is everything production demands: reliable serving, secured tool access, evaluation you can trust, and a clear owner, because an open model gives you the keys and also hands you the maintenance.
The Four Gaps Between Built and Finished
These are the same four places every open model agents build stalls, described the way Hermes actually breaks.
Security
An agent built on an open model still holds credentials and often calls real tools. We secure how it is served, scope what it can access, protect its keys, and guard against prompt injection, so running your own model does not mean running your own liability.
Publishing & Updates
Self-serving a model means you own uptime, scaling and cost. We set up reliable inference, staged releases for prompt and model changes, and a way to roll back, so an update improves the agent instead of silently changing how it answers customers.
Team & Access
Prototypes live in one notebook only their author can run. We move the agent into a real deployment with proper access, so your team can improve prompts, tools and behaviour together without redoing the setup each time.
Evaluation & Ownership
Open models give you control, which is only useful if you can measure behaviour. We build evaluation and monitoring so you know when a change makes the agent better or worse, and we assign ownership so it stays reliable in production.
Where Hermes Builds Stall
Every one of these works in the demo. Each becomes a real problem once real users, real data and a real team depend on the build.
Serving Is On You
With an open model you own inference, scaling and cost. A prototype on a spare GPU is not the same as a service that stays up under real load.
Unsecured Tool Access
Agents that call tools hold credentials and can act. Without scoping and guards, that access is a security exposure, not just a feature.
No Evaluation
Changing a prompt or model with no eval is flying blind. You cannot tell whether the agent got better or quietly worse for your users.
Prompt Injection Risk
An agent reading untrusted input can be steered into misusing its tools. Owning the model does not remove that risk, it moves it to you.
Trapped In A Notebook
Impressive demos often live in one script only their author can run. There is no deployment, no access model and no path to production.
No Owner In Production
Once live, the agent needs someone watching cost, uptime and behaviour. Without an owner, it drifts and degrades unnoticed.
What Actually Changes
Every one of these works in the demo. Each becomes a real problem the moment real people and real money depend on it.
How We Take Your Hermes Build to 100%
We work with your Hermes model and serving stack, the tools and data the agent uses, secrets management, and evaluation tooling. Nothing gets rebuilt for the sake of it, and a human stays in control of anything that touches security, money or access.
Audit the Build
We read what Hermes actually shipped and rank every issue by risk and effort, so you see exactly where the build is exposed before we touch anything.
Harden and Restructure
We close the security gaps, add the missing error handling and access controls, and clean the structure into something a person can safely maintain.
Ship and Hand Over
We set up real deployment, documentation and ownership, then hand you a build your team can run and extend, with us on hand if you want us.

We Finish What Vibe Coding Starts
Whatever you built it in, the last mile is the same: secure it, ship it, and make it something your team can own. Want your team building it right from the start?
Rather Talk It Through First
Tell us what you built with Hermes and where it is stuck. We will show you where the build is solid, where it is exposed, and what it takes to finish it.
