Soup

Fine-tune and post-train LLMs in one command. No SSH, no config hell.

---

Soup turns the pain of LLM fine-tuning into a simple workflow. One config, one command, done.

pip install 'soup-cli[train]'   # add [train] to fine-tune; bare `soup-cli` is the light CLI
soup init --template chat
soup train

Why Soup?

Training LLMs is still painful. Even experienced teams spend 30-50% of their time fighting infrastructure instead of improving models. Soup fixes that.

• Zero SSH. Never SSH into a broken GPU box again.
• One config. A simple YAML file is all you need.
• Auto everything. Batch size, GPU detection, quantization — handled.
• Works locally. Train on your own GPU with QLoRA. No cloud required.

What's New

v0.71.31 — Judge-in-the-loop suite. Put an LLM judge in the loop across the whole workflow: train against a judge, mine winners from a base model, grow instruction diversity, and decide SHIP with a true pairwise judge win-rate.

• task='online_dpo'. Online DPO (wraps TRL OnlineDPOTrainer): the model generates two completions per prompt on-policy each step and a judge (a pairwise LLM judge over your local ollama / OpenAI-compatible endpoint) — or a reward_model — picks the winner. Set training.online_dpo_judge: "ollama://llama3.1" (or reward_model, exactly one).
• soup data best-of-n. Best-of-N rejection sampling: sample N completions from --base locally, a --judge scores each, and the winner becomes an SFT row (--emit-pairs also writes winner-vs-loser DPO pairs).
• soup data evolve. WizardLM Evol-Instruct (depth / breadth) over an ollama / vllm provider — completing the synthetic-data suite (Magpie / Forge / Persona / evolve).
• soup ship --task-mode pairwise (#284). A true swap-debiased judge win-rate as the ship leg-1 task-win, fused with the catastrophic-forgetting guard into one SHIP / DON'T-SHIP verdict.
• Proof-of-mechanism, honestly. Live-validated on SmolLM2-135M: online-DPO trains with a synthetic judge (rewards/* + objective/kl logged), best-of-N samples + picks, evolve loops. Not a production RLHF claim (scale help wanted: #286).

task: online_dpo
training:
  online_dpo_judge: "ollama://llama3.1"   # a pairwise judge (or set reward_model)
  online_dpo_loss_type: sigmoid           # sigmoid | ipo
  online_dpo_max_new_tokens: 64

Quick Start

1. Install

pip install soup-cli            # light: CLI + config + data tools (no PyTorch)
pip install 'soup-cli[train]'   # add the training stack (torch, transformers, peft, trl, …)
pip install git+https://github.com/MakazhanAlpamys/Soup.git   # latest dev

soup init, soup data …, and the other data/inspection commands work on the light install. Fine-tuning (soup train) needs the [train] extra.

2. Create a config

soup init                       # interactive wizard
soup init --template chat       # or start from a template

Templates: chat, code, tool-calling, medical, reasoning, vision, kto, orpo, simpo, ipo, bco, rlhf, pretrain, moe, longcontext, embedding, audio.

3. Train, test, ship

soup train --config soup.yaml                 # LoRA, quantization, batching — all handled
soup chat  --model ./output                    # talk to your model
soup push  --model ./output --repo you/my-model

soup merge  --adapter ./output                              # merge LoRA into the base
soup export --model ./output --format gguf --quant q4_k_m   # GGUF for Ollama / llama.cpp

More export targets (ONNX, TensorRT, AWQ, GPTQ, BitNet) and deployment options live in docs/serving-and-export.md.

Configuration

A complete soup.yaml:

base: meta-llama/Llama-3.1-8B-Instruct
task: sft
# backend: unsloth  # 2-5x faster, pip install 'soup-cli[fast]'

data:
  train: ./data/train.jsonl
  format: alpaca
  val_split: 0.1

training:
  epochs: 3
  lr: 2e-5
  batch_size: auto
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

output: ./output

config/schema.py is the single source of truth for every field. Advanced data, training, and PEFT options are documented under Documentation.

Supported Models

Soup works with any text-generation model on the HuggingFace Hub — if it loads with AutoModelForCausalLM, it works, zero config changes. Llama 3.x/4, Qwen 2.5/3, Gemma 3, Mistral, Mixtral, DeepSeek R1/V3, Phi-4, and 100+ others ship as ready-made recipes (soup recipes list).

VRAM	Max model (QLoRA 4-bit)	Example
8 GB	~7B	Llama-3.1-8B, Mistral-7B
16 GB	~14B	Phi-4-14B, Qwen2.5-14B
24 GB	~34B	CodeLlama-34B, Yi-1.5-34B
48 GB	~70B	Llama-3.3-70B
80 GB+	70B+ (full) or MoE	Mixtral-8x22B, DeepSeek-V3

Full model + vision tables and the optional-extras matrix are in docs/models.md.

Docker

Run Soup without installing CUDA or PyTorch locally (image published to GHCR on every release):

docker pull ghcr.io/makazhanalpamys/soup:latest
docker run --gpus all -v $(pwd):/workspace ghcr.io/makazhanalpamys/soup train --config soup.yaml
docker compose up   # or build locally

Requirements

• Python 3.10+
• GPU with CUDA (recommended), Apple Silicon (MPS), or CPU (experimental — very slow)
• 8 GB+ VRAM for 7B models with QLoRA

All training tasks run on CPU for testing (quantization auto-disabled). Optional extras (train, all, fast, vision, qat, serve, serve-fast, ui, eval, deepspeed, liger, mlx, onnx, tensorrt, …) are listed in docs/models.md.

Troubleshooting

soup doctor    # GPU, system resources, dependencies, and version in one place

• ImportError: DLL load failed while importing _C (Windows) — reinstall PyTorch for your CUDA version: pip install torch --index-url https://download.pytorch.org/whl/cu121.
• soup version ≠ pip show soup-cli — multiple Python installs; use a virtualenv.

Development

git clone https://github.com/MakazhanAlpamys/Soup.git
cd Soup
pip install -e ".[dev]"

ruff check src/soup_cli/ tests/    # lint
pytest tests/ -v                   # unit tests (fast, no GPU)
pytest tests/ -m smoke -v          # smoke tests (downloads a tiny model, trains)

pre-commit install                 # optional: ruff lint+format on commit
