Question 1

Can I connect a Hermes agent to BenchGen?

Accepted Answer

Yes. Hermes agents can be connected to BenchGen and registered on the platform, which was added in release 0.7.0. Once registered, a Hermes agent can be selected and evaluated alongside other models. See the release notes in the docs for details.

Question 2

What does BenchGen score?

Accepted Answer

Every run is scored on five quality dimensions: tool-call accuracy (target 85% or higher), skill coverage (80% or higher), goal completion (78% or higher), memory utilisation (75% or higher) and regression stability (within 5 points between runs). Each claim carries its verification method: programmatic, LLM judge or unverified.

Question 3

How is this different from reading logs?

Accepted Answer

Logs tell you what happened. BenchGen records the full State, Action, Tool Response, Outcome and Reward trajectory of a run, aggregates it across many runs and groups failures into recurring patterns, so you can see which fix to try first.

Question 4

What is the difference between a harness fix and a fine-tune?

Accepted Answer

A harness fix changes the skills, memory, routing or guardrails around the model. It is instant, needs no GPU and works with any model. A fine-tune changes the model weights. BenchGen suggests starting with harness fixes and moving to a fine-tune when the same failure keeps recurring across diverse tasks.

Question 5

Which models can be fine-tuned?

Accepted Answer

Fine-tuning applies to open-weight models, for example Llama 4, Qwen 3 and Gemma 4, because LoRA training needs access to the weights. For closed models such as GPT or Claude, scoring and evaluation work the same way, and the recommendation is a harness fix.

Question 6

Do I need a GPU?

Accepted Answer

No. Benchmarking and scoring run on the BenchGen platform, in the cloud or on your own Kubernetes cluster with Helm. GPU capacity is only used when you run a fine-tune.
