What is model-trainer?

A guide to training and fine-tuning language models with TRL on Hugging Face Jobs, a hosted service for running machine-learning jobs. It covers supervised fine-tuning, preference-based methods, reward modeling, and GGUF conversion for local deployment.

Use it to train or adapt language models, apply preference or reward-based training, and convert models for local deployment.

It explains how to run different language-model training approaches in the hosted environment and prepare models for local use.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00128	$0.06865
Opus 5	$0.00064	$0.03432
Sonnet 5	$0.00026	$0.01373
Haiku 4.5	$0.00013	$0.00686

Measured 5d ago against content hash fb13b3a3e405, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

model-trainer 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 5d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (skills/model-trainer/scripts/convert_to_gguf.py, skills/model-trainer/scripts/dataset_inspector.py, skills/model-trainer/scripts/estimate_cost.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

16 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
