Back to Articles Train AI models with Unsloth and Hugging Face Jobs for FREE Published February 20, 2026 Update on GitHub ben burtenshaw burtenshaw Follow Daniel (Unsloth) danielhanchen Follow unsloth Michael Han shimmyshimmer Follow unsloth Maxime Labonne mlabonne Follow LiquidAI Daniel van Strien davanstrien Follow shaun smith evalstate Follow This blog post covers how to use Unsloth and Hugging Face Jobs for fast LLM fine-tuning (specifically LiquidAI/LFM2.5-1.2B-Instruct ) through coding agents like Claude Code and Codex. Unsloth provides ~2x faster training and ~60% less VRAM usage compared to standard methods, so training small models can cost just a few dollars. Why a small model? Small language models like LFM2.5-1.2B-Instruct are ideal candidates for fine-tuning. They are cheap to train, fast to iterate on, and increasingly competitive with much larger models on focused tasks. LFM2.5-1.2B-Instruct runs under 1GB of memory and is optimized for on-device deployment, so what you fine-tune can be served on CPUs, phones, and laptops. You will need We are giving away free credits to fine-tune models on Hugging Face Jobs. Join the Unsloth Jobs Explorers organization to claim your free credits and one-month Pro subscription. A Hugging Face account (required for HF Jobs) Billing setup (for verification, you can monitor your usage and manage your billing in your billing page). A Hugging Face token with write permissions (optional) A coding agent (Open Code, Claude Code, or Codex) Run the Job If you want to train a model using HF Jobs and Unsloth, you can simply use the hf jobs CLI to submit a job. First, you need to install the hf CLI. You can do this by running the following command: # mac or linux curl -LsSf https://hf.co/cli/install.sh | bash Next you can run the following command to submit a job: hf jobs uv run https://huggingface.co/datasets/unsloth/jobs/resolve/main/sft-lfm2.5.py \ --flavor a10g-small \ --secrets HF_TOKEN \ --timeout 4h \ --dataset mlabonne/FineTome-100k \ --num-epochs 1 \ --eval-split 0.2 \ --output-repo your-username/lfm-finetuned Check out the training script and Hugging Face Jobs documentation for more details. Installing the Skill Hugging Face model training skill lowers barrier of entry to train a model by simply prompting. First, install the skill with your coding agent. Claude Code Claude Code discovers skills through its plugin system, so we need to install the Hugging Face skills first. To do so: Add the marketplace: /plugin marketplace add huggingface/skills Browse available skills in the Discover tab: /plugin Install the model trainer skill: /plugin install hugging-face-model-trainer@huggingface-skills For more details, see the documentation on using the hub with skills or the Claude Code Skills docs. Codex Codex discovers skills through AGENTS.md files and .agents/skills/ directories. Install individual skills with $skill-installer: $skill-installer install https://github.com/huggingface/skills/tree/main/skills/hugging-face-model-trainer For more details, see the Codex Skills docs and the AGENTS.md guide. Anything else A generic install method is simply to clone the skills repository and copy the skill to your agent's skills directory. git clone https://github.com/huggingface/skills.git mkdir -p ~/.agents/skills && cp -R skills/skills/hugging-face-model-trainer ~/.agents/skills/ Quick Start Once the skill is installed, ask your coding agent to train a model: Train LiquidAI/LFM2.5-1.2B-Instruct on mlabonne/FineTome-100k using Unsloth on HF Jobs The agent will generate a training script based on an example in the skill, submit the training to HF Jobs, and provide a monitoring link via Trackio. How It Works Training jobs run on Hugging Face Jobs, fully managed cloud GPUs. The agent: Generates a UV script with inline dependencies Submits it to HF Jobs via the hf CLI Reports the job ID and monitoring URL Pushes the trained model to your Hugging Face Hub repository Example Training Script The skill generates scripts like this based on the example in the skill. # /// script # dependencies = ["unsloth", "trl>=0.12.0", "datasets", "trackio"] # /// from unsloth import FastLanguageModel from trl import SFTTrainer, SFTConfig from datasets import load_dataset model, tokenizer = FastLanguageModel.from_pretrained( "LiquidAI/LFM2.5-1.2B-Instruct", load_in_4bit=True, max_seq_length=2048, ) model = FastLanguageModel.get_peft_model( model, r=16, lora_alpha=32, lora_dropout=0, target_modules=[ "q_proj", "k_proj", "v_proj", "out_proj", "in_proj", "w1", "w2", "w3", ], ) dataset = load_dataset("trl-lib/Capybara", split="train") trainer = SFTTrainer( model=model, tokenizer=tokenizer, train_dataset=dataset, args=SFTConfig( output_dir="./output", push_to_hub=True, hub_model_id="username/my-model", per_device_train_batch_size=4, gradient_accumulation_steps=4, num_train_epochs=1, learning_rate=2e-4, report_to="trackio", ), ) trainer.train() trainer.push_to_hub() Model Size Recommended GPU Approx Cost/hr <1B params t4-small ~$0.40 1-3B params t4-medium ~$0.60 3-7B params a10g-small ~$1.00 7-13B params a10g-large ~$3.00 For a full overview of Hugging Face Spaces pricing, check out the guide here. Tips for Working with Coding Agents Be specific about the model and dataset to use, and include Hub IDs (for example, Qwen/Qwen2.5-0.5B and trl-lib/Capybara). Agents will search for and validate those combinations. Mention Unsloth explicitly if you want it used. Otherwise, the agent will choose a framework based on the model and budget. Ask for cost estimates before launching large jobs. Request Trackio monitoring for real-time loss curves. Check job status by asking the agent to inspect logs after submission.
