Short on time? Here's the quick answer

We've tested both tools. Here's who should pick what:

Google Vertex AI

Unified AI platform for ML development

Best for you if:

  • • Google Vertex AI is a unified ML platform for building, deploying, and managing AI models
  • • It provides AutoML, custom training, model registry, and deployment to endpoints

Soup CLI

Fine-tune any LLM on a 4GB GPU with layer streaming

Best for you if:

  • • You need something completely free
  • • Fine-tune 8B models on a 4GB GPU using layer streaming instead of loading the entire frozen base into VRAM.
  • • Automatically writes training configs, validates data, and gates saves with a SHIP/DON'T-SHIP verdict.

Value 85/100. Google Vertex AI's pricing is generally fair, offering a generous free tier with $300 credits for 90 days, which is excellent for initial exploration.

Watch out: Data storage costs not included

Soup CLISoup CLI

Fine-tune any LLM on a 4GB GPU with layer streaming

Strengths

  • +Enables fine-tuning of large models on low-cost consumer GPUs that would otherwise be impossible
  • +Fully open source and free with no paid tier or vendor lock-in
  • +Comprehensive automation: from data validation to config writing to model evaluation

Weaknesses

  • -Layer streaming is still in BETA with known edge cases and limitations (text-only, plain LoRA, specific architectures)
  • -Requires Python 3.10 to 3.12 and is primarily designed for CUDA-based GPUs

Key features

Layer streaming: fine-tune models up to 8B on a 4GB GPU by streaming decoder layers from CPU/NVMe23 training methods: SFT, DPO, ORPO, SimPO, KTO, and moreAutomatic config generation: writes task, quantization, LR, and epochs based on rules, not searchPre-flight data validation: refuses runs that won't fit on hardwareSelf-correcting: catches reward hacking mid-run rather than just haltingMigration command: converts configs from LLaMA-Factory, Axolotl, and Unsloth
