omh-model-finetuning

omh-model-finetuning is a skill for Claude Code, Codex from rlaope/oh-my-hermes. It costs 118 tokens per session (1,970 once invoked), scanned A, original, MIT.

A workflow for fine-tuning an existing machine-learning model with example data. Fine-tuning changes a model using demonstrations, preference pairs, or answers that a program can check.

In plain words
What is it for?
Use it to assess and plan supervised fine-tuning or preference training, compare results with a baseline, and decide whether training is warranted.
Why use it?
It starts by comparing the untuned model and its best prompt on held-out examples, so training is not assumed to be necessary. It also distinguishes different data shapes before choosing a method.

About the project

oh-my-hermes is an operating layer for Hermes Agent that organizes requests into workflows for planning, research, creation, coding handoffs, operations, and project memory. Hermes users run these workflows through the desktop app, CLI, or messenger app, while the catalogue add-ons extend its native capabilities.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

omh-model-finetuning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Model Finetuning

This is an OMH model-finetuning workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).

Why This Exists

model-finetuning exists because producing a model had no owner: inference-serving serves one that exists and llm-app-dev builds on top of one, while an SFT or DPO question had no baseline comparison and no way to answer that training is not needed.

First Steps

  • Ask what the untuned model and the best prompt score on the held-out examples before discussing any method.
  • Ask what shape the data has -- demonstrations, preference pairs, or answers a program can check.

Do Not Use When

  • The ask is onboarding a new model generation into OMH's routing, calibration, or pricing.
  • The ask is serving an existing model behind an endpoint or benchmarking that endpoint; use omh-inference-serving.
  • The ask is building an application on top of a hosted model -- RAG, structured output, prompt versions; use omh-llm-app-dev.
  • The ask is learning from an OMH run, a missed route, or a skill improvement candidate.

Examples

Good example:

  • Prompt: should we fine-tune a model for our support replies or is a better prompt enough
  • Expected behavior: Ask for the held-out examples and the current prompt's score, try few-shot and retrieval against them, and return do_not_finetune if one closes the gap; otherwise pick SFT from the reply demonstrations and gate promotion on beating the untuned baseline.
  • Why: Most prompt-shaped gaps close without training, and training first hides that the cheaper fix was enough.

Bad example:

  • Prompt: the fine-tuned checkpoint got 0.82 on our eval, ship it
  • Expected behavior: Refuse to promote on a standalone score: run the same held-out eval on the untuned baseline and compare before promotion.
  • Why: A score with no baseline cannot show the training helped at all.

Completion Checklist

  • The fine-tune decision is stated, and do_not_finetune was considered first.
  • The method is chosen from the data's shape and its failure mode is named.
  • The held-out split was drawn before training and checked for overlap.
  • Promotion cites the same eval observed on the untuned baseline and the candidate.
  • OMH ran nothing, and every score cites observed output or is marked unverified.
