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

pip install soup-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.

Quick Start

1. Install

# From PyPI (recommended):
pip install soup-cli

# Or from GitHub (latest dev):
pip install git+https://github.com/MakazhanAlpamys/Soup.git

2. Create config

# Interactive wizard
soup init

# Or use a template
soup init --template chat       # conversational fine-tune
soup init --template code       # code generation
soup init --template medical    # domain expert
soup init --template reasoning  # GRPO reasoning training
soup init --template vision     # vision/multimodal fine-tune
soup init --template kto        # KTO unpaired preference alignment
soup init --template orpo       # ORPO (no reference model needed)
soup init --template simpo      # SimPO length-normalized preference
soup init --template ipo        # IPO regularized preference
soup init --template rlhf       # full RLHF pipeline (SFT→RM→PPO)
soup init --template pretrain   # continued pre-training on raw text
soup init --template moe        # MoE fine-tuning (ScatterMoE LoRA)
soup init --template longcontext # 128k+ context fine-tuning
soup init --template embedding  # sentence embedding fine-tuning
soup init --template audio      # audio/speech model fine-tuning

3. Train

soup train --config soup.yaml

That's it. Soup handles LoRA setup, quantization, batch size, monitoring, and checkpoints.

4. Test your model

soup chat --model ./output

5. Push to HuggingFace

soup push --model ./output --repo your-username/my-model

6. Merge & Export

# Merge LoRA adapter with base model
soup merge --adapter ./output

# Export to GGUF for Ollama / llama.cpp
soup export --model ./output --format gguf --quant q4_k_m

# Export to ONNX (pip install 'soup-cli[onnx]')
soup export --model ./output --format onnx

# Export to TensorRT-LLM (pip install 'soup-cli[tensorrt]')
soup export --model ./output --format tensorrt

Config Example

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

Unsloth Backend (2-5x Faster Training)

Use the Unsloth backend for significantly faster training and up to 80% less VRAM:

# Install unsloth support
pip install 'soup-cli[fast]'

Then add one line to your config:

base: meta-llama/Llama-3.1-8B-Instruct
task: sft
backend: unsloth  # 2-5x faster, -80% VRAM

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

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

Works with all training tasks: SFT, DPO, GRPO, PPO, KTO, ORPO, SimPO, IPO, and Pretrain. If unsloth is installed but not enabled, Soup will suggest it automatically.

Tip: Soup auto-detects unsloth. When installed, you'll see a hint during soup train if you haven't enabled it yet.

Continued Pre-training

Continue training a model on raw text for domain adaptation:

base: meta-llama/Llama-3.1-8B
task: pretrain

data:
  train: ./data/corpus.jsonl   # {"text": "..."} or plain .txt files
  format: plaintext
  max_length: 4096

training:
  epochs: 1
  lr: 1e-5
  quantization: 4bit

soup init --template pretrain
soup train

MoE Model Support

Fine-tune Mixture of Experts models (Mixtral, Qwen3-30B-A3B, DeepSeek V3) with ScatterMoE LoRA — applies LoRA to both attention layers and expert FFN layers:

base: Qwen/Qwen3-30B-A3B
task: sft

training:
  moe_lora: true              # target expert + attention layers
  moe_aux_loss_coeff: 0.01    # router load-balancing loss
  quantization: 4bit

Soup auto-detects MoE architectures. Works with all training tasks.

soup init --template moe
soup train

Vision / Multimodal Fine-tuning

Fine-tune vision-language models (LLaMA-3.2-Vision, Qwen2-VL, Pixtral) on image+text data:

# Install vision support
pip install 'soup-cli[vision]'

# Create a vision config
soup init --template vision

# Train
soup train --config soup.yaml

base: meta-llama/Llama-3.2-11B-Vision-Instruct
task: sft
modality: vision

data:
  train: ./data/vision_train.jsonl
  format: llava
  image_dir: ./data/images
  val_split: 0.1

training:
  epochs: 3
  lr: 1e-5
  quantization: 4bit
  lora:
    r: 64
    alpha: 16

Supported vision data formats:

LLaVA:

{"image": "photo.jpg", "conversations": [{"from": "human", "value": "<image>\nDescribe this image."}, {"from": "gpt", "value": "A cat on a mat."}]}

ShareGPT4V:

{"image": "chart.png", "conversations": [{"from": "human", "value": "<image>\nWhat does this show?"}, {"from": "gpt", "value": "Quarterly revenue."}]}

soup data inspect automatically shows image statistics (count, formats, missing files) for vision datasets.

Audio / Speech Fine-tuning

Fine-tune audio-language models (Qwen2-Audio, Whisper) on audio+text data:

# Install audio support
pip install 'soup-cli[audio]'

# Create an audio config
soup init --template audio

# Train
soup train --config soup.yaml

base: Qwen/Qwen2-Audio-7B-Instruct
task: sft
modality: audio

data:
  train: ./data/audio_train.jsonl
  format: audio
  audio_dir: ./data/audio
  val_split: 0.1

training:
  epochs: 3
  lr: 1e-5
  quantization: 4bit
  lora:
    r: 64
    alpha: 16

Audio data format:

{"audio": "recording.wav", "messages": [{"role": "user", "content": "Transcribe this audio."}, {"role": "assistant", "content": "Hello world."}]}

Quantization-Aware Training (QAT)

Train with simulated quantization for significantly better post-quantization quality compared to standard QLoRA:

# Install QAT support
pip install 'soup-cli[qat]'

base: meta-llama/Llama-3.1-8B-Instruct
task: sft

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

training:
  epochs: 3
  lr: 2e-5
  quantization: 4bit
  quantization_aware: true  # Enable QAT
  lora:
    r: 64
    alpha: 16

output: ./output

When to use QAT vs post-training quantization:

• QAT (quantization_aware: true): Better quality when you plan to deploy with aggressive quantization (int8/int4). ~5-10% slower training, but the model learns to compensate for quantization noise.
• Post-training quantization (default): Faster training, good enough for most use cases. Quantize after training with soup export --quant q4_k_m.

QAT works with all training tasks (SFT, DPO, GRPO, PPO, KTO, ORPO, SimPO, IPO, Pretrain) and vision modality. Not compatible with the unsloth backend. After QAT training, export to GGUF normally with soup export.

DPO Training

Train with preference data using Direct Preference Optimization:

base: meta-llama/Llama-3.1-8B-Instruct
task: dpo

data:
  train: ./data/preferences.jsonl
  format: dpo

training:
  epochs: 3
  dpo_beta: 0.1
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

GRPO Training (Reasoning)

Train reasoning models with Group Relative Policy Optimization (DeepSeek-R1 style):

base: meta-llama/Llama-3.1-8B-Instruct
task: grpo

data:
  train: ./data/reasoning_train.jsonl
  format: sharegpt
  max_length: 4096

training:
  epochs: 3
  lr: 1e-5
  grpo_beta: 0.1
  num_generations: 4
  reward_fn: accuracy   # or 'format', or path to custom .py
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

# Create a reasoning config
soup init --template reasoning

# Train
soup train --config soup.yaml

Built-in reward functions:

• accuracy — checks if the final answer matches expected (supports #### and \boxed{} formats)
• format — checks for structured <think>...</think> reasoning blocks

Custom reward functions — point to a Python file:

# my_reward.py
def reward_fn(completions, **kwargs):
    """Score each completion. Return list of floats."""
    return [1.0 if "correct" in c[-1]["content"] else 0.0 for c in completions]

training:
  reward_fn: ./my_reward.py

PPO / Full RLHF Pipeline

Train models with the full RLHF pipeline: SFT warmup → Reward Model → PPO alignment.

# Create an RLHF config
soup init --template rlhf

Step 1: SFT warmup — fine-tune a base model on your data:

base: meta-llama/Llama-3.1-8B-Instruct
task: sft
data:
  train: ./data/train.jsonl
  format: alpaca
output: ./output_sft

Step 2: Train reward model — learn preferences from human feedback:

base: meta-llama/Llama-3.1-8B-Instruct
task: reward_model
data:
  train: ./data/preferences.jsonl
  format: dpo
output: ./output_rm

Step 3: PPO alignment — optimize the policy using the reward model:

base: meta-llama/Llama-3.1-8B-Instruct
task: ppo
data:
  train: ./data/prompts.jsonl
  format: chatml
training:
  reward_model: ./output_rm
  ppo_epochs: 4
  ppo_clip_ratio: 0.2
  ppo_kl_penalty: 0.05
  lora:
    r: 64
    alpha: 16
  quantization: 4bit
output: ./output_ppo

PPO supports two reward sources:

• Reward model (reward_model): pre-trained reward model (from step 2)
• Reward function (reward_fn): callable function (same as GRPO — accuracy, format, or custom .py)

KTO Training (Unpaired Preferences)

Train with unpaired preference data — no need for chosen+rejected pairs:

base: meta-llama/Llama-3.1-8B-Instruct
task: kto

data:
  train: ./data/kto_train.jsonl
  format: kto

training:
  epochs: 3
  kto_beta: 0.1
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

KTO data format:

{"prompt": "What is 2+2?", "completion": "4", "label": true}
{"prompt": "What is 2+2?", "completion": "Fish", "label": false}

ORPO Training (No Reference Model)

ORPO combines SFT and alignment in one step — no reference model needed:

base: meta-llama/Llama-3.1-8B-Instruct
task: orpo

data:
  train: ./data/preferences.jsonl
  format: dpo

training:
  epochs: 3
  orpo_beta: 0.1
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

SimPO Training (Simple Preference)

SimPO uses length-normalized log probabilities as implicit rewards — reference-free:

base: meta-llama/Llama-3.1-8B-Instruct
task: simpo

data:
  train: ./data/preferences.jsonl
  format: dpo

training:
  epochs: 3
  simpo_gamma: 0.5
  cpo_alpha: 1.0
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

IPO Training (Regularized Preference)

IPO is a theoretically grounded DPO variant with stronger regularization:

base: meta-llama/Llama-3.1-8B-Instruct
task: ipo

data:
  train: ./data/preferences.jsonl
  format: dpo

training:
  epochs: 3
  ipo_tau: 0.1
  lora:
    r: 64
    alpha: 16
  quantization: 4bit

DoRA (Weight-Decomposed LoRA)

Enable DoRA for improved LoRA quality with magnitude decomposition:

training:
  lora:
    r: 64
    alpha: 16
    use_dora: true  # Enable DoRA

Works with all training tasks and backends.

LoRA+ (Differentiated Learning Rates)

Use different learning rates for LoRA A and B matrices:

training:
  lr: 2e-5
  loraplus_lr_ratio: 16.0  # lr_B = lr × 16
  lora:
    r: 64
    alpha: 16

GaLore (Memory-Efficient Full-Parameter Training)

Train without LoRA using gradient low-rank projection — saves optimizer memory:

base: meta-llama/Llama-3.1-8B-Instruct
task: sft

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

training:
  epochs: 3
  lr: 2e-5
  quantization: none      # Required: GaLore is incompatible with quantization
  use_galore: true
  galore_rank: 128
  galore_update_proj_gap: 200
  galore_scale: 0.25

Note: GaLore requires quantization: none and backend: transformers (not unsloth).

Chat with your model

# Chat with a LoRA adapter (auto-detects base model)
soup chat --model ./output

# Specify base model explicitly
soup chat --model ./output --base meta-llama/Llama-3.1-8B-Instruct

# Adjust generation
soup chat --model ./output --temperature 0.3 --max-tokens 256

Push to HuggingFace

# Upload model to HF Hub
soup push --model ./output --repo your-username/my-model

# Make it private
soup push --model ./output --repo your-username/my-model --private

Merge LoRA Adapter

Merge a LoRA adapter with its base model into a standalone model:

# Auto-detect base model from adapter_config.json
soup merge --adapter ./output --output ./merged

# Specify base model and dtype
soup merge --adapter ./output --base meta-llama/Llama-3.1-8B --dtype bfloat16

Export to GGUF

Export models to GGUF format for use with Ollama and llama.cpp:

# Export LoRA adapter (auto-merges with base, then converts)
soup export --model ./output --format gguf --quant q4_k_m

# Export with different quantizations
soup export --model ./output --format gguf --quant q8_0
soup export --model ./output --format gguf --quant f16

# Export a full (already merged) model
soup export --model ./merged --format gguf

# Specify llama.cpp path manually
soup export --model ./output --format gguf --llama-cpp /path/to/llama.cpp

Supported quantizations: q4_0, q4_k_m, q5_k_m, q8_0, f16, f32

ONNX Export

Export models to ONNX format for use with ONNX Runtime:

pip install 'soup-cli[onnx]'
soup export --model ./output --format onnx
soup export --model ./output --format onnx --output ./model_onnx

TensorRT-LLM Export

Export models to TensorRT-LLM format for high-throughput GPU inference:

pip install 'soup-cli[tensorrt]'
soup export --model ./output --format tensorrt
soup export --model ./output --format tensorrt --output ./model_trt

After export, use with Ollama manually or auto-deploy:

# Manual (3-step)
echo 'FROM ./my-model.q4_k_m.gguf' > Modelfile
ollama create my-model -f Modelfile
ollama run my-model

# Auto-deploy (1-step)
soup export --model ./output --format gguf --deploy ollama --deploy-name my-model

Deploy to Ollama

Deploy a GGUF model directly to your local Ollama instance:

# Deploy a GGUF model
soup deploy ollama --model ./output/model.q4_k_m.gguf --name soup-my-model

# Deploy with system prompt and parameters
soup deploy ollama --model ./model.gguf --name soup-chat \
  --system "You are a helpful assistant." \
  --template chatml \
  --parameter temperature=0.7 \
  --parameter top_p=0.9

# Export + deploy in one command
soup export --model ./output --format gguf --deploy ollama

# List Soup-deployed models
soup deploy ollama --list

# Remove a model
soup deploy ollama --remove soup-my-model

Auto-detected chat templates: chatml, llama, mistral, vicuna, zephyr (or auto to infer from soup.yaml).

Resume Training

Resume a training run from a checkpoint:

# Auto-detect latest checkpoint in output directory
soup train --config soup.yaml --resume auto

# Resume from a specific checkpoint
soup train --config soup.yaml --resume ./output/checkpoint-500

Batch Inference

Run a model on a list of prompts and save results:

# JSONL input (each line: {"prompt": "..."})
soup infer --model ./output --input prompts.jsonl --output results.jsonl

# Plain text input (one prompt per line)
soup infer --model ./output --input prompts.txt --output results.jsonl

# Custom generation settings
soup infer --model ./output --input prompts.jsonl --output results.jsonl \
  --max-tokens 512 --temperature 0.3

Output is JSONL with prompt, response, and tokens_generated fields. Shows a progress bar and throughput summary.

TensorBoard Integration

Log training metrics to TensorBoard for local visualization:

# Enable TensorBoard logging (requires: pip install tensorboard)
soup train --config soup.yaml --tensorboard

# View logs
tensorboard --logdir ./output/runs/

Note: --tensorboard and --wandb cannot be used together. Pick one.

Weights & Biases Integration

Send training metrics to W&B for cloud-based experiment tracking:

# Enable W&B logging (requires: pip install wandb)
soup train --config soup.yaml --wandb

Make sure WANDB_API_KEY is set or run wandb login first.

Inference Server

Start a local OpenAI-compatible inference server:

# Install server dependencies
pip install 'soup-cli[serve]'

# Start server
soup serve --model ./output --port 8000

# With custom settings
soup serve --model ./output --port 8080 --host 127.0.0.1 --max-tokens 1024

Endpoints:

• POST /v1/chat/completions — chat completions (streaming supported)
• GET /v1/models — list available models
• GET /health — health check

Compatible with OpenAI SDK:

from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="unused")
response = client.chat.completions.create(
    model="output",
    messages=[{"role": "user", "content": "Hello!"}],
)

vLLM Backend (2-4x Faster Inference)

Use vLLM for significantly better throughput in production:

# Install vLLM support
pip install 'soup-cli[serve-fast]'

# Start with vLLM backend
soup serve --model ./output --backend vllm

# Multi-GPU with tensor parallelism
soup serve --model ./output --backend vllm --tensor-parallel 2

# Control GPU memory usage
soup serve --model ./output --backend vllm --gpu-memory 0.8

Tip: Soup auto-detects vLLM. When installed, you'll see a hint during soup serve if you haven't enabled it yet.

SGLang Backend (v0.17.0+)

Use SGLang as an alternative high-throughput backend:

# Install SGLang support
pip install 'soup-cli[sglang]'

# Start with SGLang backend
soup serve --model ./output --backend sglang

# Multi-GPU with tensor parallelism
soup serve --model ./output --backend sglang --tensor-parallel 2

Speculative Decoding (v0.16.0+)

Use a smaller draft model to speed up generation (2-3x faster):

# Transformers backend — uses HF assisted generation
soup serve --model ./output --speculative-decoding small-draft-model --spec-tokens 5

# vLLM backend — uses vLLM native speculative decoding
soup serve --model ./output --backend vllm --speculative-decoding small-draft-model

Note (v0.10.10+): max_tokens is capped at 16,384 per request. Error details are never exposed in HTTP responses.

Synthetic Data Generation

Generate training data using LLMs:

# Generate using OpenAI API
soup data generate --prompt "Create math word problems" --count 100 --format alpaca

# Use a different model
soup data generate --prompt "Medical Q&A pairs" --model gpt-4o --count 500

# Deduplicate against existing data
soup data generate --prompt "..." --count 200 --dedup-with existing.jsonl

# Use seed examples to guide style
soup data generate --prompt "..." --seed examples.jsonl --count 100

# Use a local OpenAI-compatible server (soup serve, Ollama, etc.)
soup data generate --prompt "..." --provider server --api-base http://localhost:11434/v1

Hyperparameter Sweep

Search for the best hyperparameters:

# Grid search over learning rate and LoRA rank
soup sweep --config soup.yaml --param lr=1e-5,2e-5,5e-5 --param lora_r=8,16,32

# Random search with max runs
soup sweep --config soup.yaml --param lr=1e-5,2e-5,5e-5 --strategy random --max-runs 5

# Preview without running
soup sweep --config soup.yaml --param lr=1e-5,2e-5 --param epochs=2,3 --dry-run

# Early stopping: skip remaining runs if loss exceeds 1.5x best
soup sweep --config soup.yaml --param lr=1e-5,2e-5,5e-5 --early-stop 1.5

Model Comparison

Compare outputs of two models side-by-side:

# Compare with inline prompts
soup diff --model-a ./model_v1 --model-b ./model_v2 --prompt "Explain gravity"

# Compare with a prompts file
soup diff --model-a ./base --model-b ./finetuned --prompts test_prompts.jsonl

# Save results
soup diff --model-a ./a --model-b ./b --prompts prompts.txt --output results.jsonl

Multi-GPU / DeepSpeed / FSDP

Train on multiple GPUs with DeepSpeed or PyTorch FSDP2:

# DeepSpeed ZeRO Stage 2 (recommended for most cases)
soup train --config soup.yaml --deepspeed zero2

# DeepSpeed ZeRO Stage 3 (for very large models)
soup train --config soup.yaml --deepspeed zero3

# DeepSpeed ZeRO Stage 2 with CPU offload (memory-constrained)
soup train --config soup.yaml --deepspeed zero2_offload

# FSDP2 Full Shard (native PyTorch, like ZeRO-3)
soup train --config soup.yaml --fsdp full_shard

# FSDP2 Shard Grad Op (like ZeRO-2)
soup train --config soup.yaml --fsdp shard_grad

# FSDP2 Full Shard with CPU offload
soup train --config soup.yaml --fsdp full_offload

Performance + Long-Context

Optimize training throughput and extend context windows:

# soup.yaml — performance options
training:
  use_liger: true            # Liger Kernel fused ops (20-60% memory savings)
  use_flash_attn: true       # FlashAttention v2/v3 auto-detection
  gradient_checkpointing: true  # Required for long sequences

  # Long-context (128k+ tokens)
  rope_scaling_type: dynamic  # RoPE scaling: linear, dynamic, yarn, longrope
  # use_ring_attention: true  # Sequence parallelism across GPUs

data:
  max_length: 131072          # Up to 1M tokens supported

Install optional performance packages:

pip install 'soup-cli[liger]'     # Liger Kernel fused operations
pip install flash-attn --no-build-isolation  # FlashAttention
pip install 'soup-cli[ring-attn]' # Ring FlashAttention (sequence parallelism)

Quickstart Demo

Run a complete demo in one command — creates sample data, config, and trains a tiny model:

# Full demo (creates data + config + trains TinyLlama)
soup quickstart

# Just create files without training
soup quickstart --dry-run

# Skip confirmation
soup quickstart --yes

Health Check

Check your environment for compatibility issues:

soup doctor

Shows: Python version, GPU availability, all dependency versions, and fix suggestions.

Version Info

# Basic version
soup version

# Full system info (useful for bug reports)
soup version --full
# -> soup v0.17.3 | Python 3.11.5 | CUDA 12.1 | extras: serve, data

Web UI

Launch a local web interface to manage experiments, start training, explore data, and chat with models — all from your browser.

pip install 'soup-cli[ui]'
soup ui
# -> opens http://127.0.0.1:7860 in your browser
# -> prints auth token to console

Pages:

• Dashboard — view all experiment runs, loss charts, system info
• New Training — create configs from templates, validate, and start training
• Data Explorer — browse and inspect datasets (JSONL, JSON, CSV, Parquet)
• Model Chat — chat with a running soup serve inference server

Security (v0.10.10+): The Web UI generates a random auth token at startup (printed to console). All mutating endpoints (start/stop training, delete runs, inspect data, validate config) require Authorization: Bearer <token> header. CORS is restricted to the served origin. Data inspection is sandboxed to the working directory.

# Custom port, don't auto-open browser
soup ui --port 8080 --no-browser

Error Handling

Soup shows friendly error messages by default (2-3 lines with a fix suggestion). For full tracebacks:

# Global flag goes BEFORE the command
soup --verbose train --config soup.yaml

# Works with any command
soup --verbose eval --model ./output --benchmarks mmlu

Note: --verbose is a global flag — it must go before the command name, not after.

Note: Soup auto-detects your GPU and estimates the optimal batch size. Use soup doctor to check your setup.

Requirements

• Python 3.9+
• GPU with CUDA (recommended) or Apple Silicon (MPS) or CPU (experimental)
• 8 GB+ VRAM for 7B models with QLoRA

CPU note: All training tasks (SFT, DPO, GRPO, PPO, KTO, ORPO, SimPO, IPO, Pretrain) work on CPU but will be very slow. Quantization (4bit/8bit) is auto-disabled on CPU. GRPO on CPU uses min_new_tokens=1 to prevent empty generation errors. A default chat template is set automatically if the tokenizer lacks one. PPO datasets are tokenized before training to ensure compatibility with trl's experimental API.

Troubleshooting

ImportError: DLL load failed while importing _C (Windows)

PyTorch's C extension fails to load. Common causes:

# Fix: reinstall PyTorch with the correct CUDA version
pip install torch --index-url https://download.pytorch.org/whl/cu121

# Or for CPU-only
pip install torch --index-url https://download.pytorch.org/whl/cpu

Multiple Python versions conflict

If pip show soup-cli shows a different version than soup version, you have multiple Python installations with separate packages.

# Check which Python is active
python --version
which python    # Linux/macOS
where python    # Windows

# Fix: use a virtual environment
python -m venv .venv
source .venv/bin/activate    # Linux/macOS
.venv\Scripts\activate       # Windows
pip install soup-cli

Quick environment check

soup doctor    # Shows GPU, dependencies, and version info

Development

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

# Lint
ruff check soup_cli/ tests/

# Run unit tests (fast, no GPU needed)
pytest tests/ -v

# Run smoke tests (downloads tiny model, runs real training)
pytest tests/ -m smoke -v
