Custom model training supports both full fine-tuning and LoRA-based efficient tuning, producing models that understand your domain, terminology, and style. Pricing is straightforward per-token with no minimum commitments, and rates are competitive with major providers. The free tier provides limited credits for exploration.

The tool is best suited for developers building on open-source models with fine-tuning needs. Pricing starts at Pay-per-use · From $0.10/M tokens · Fine-tuning from $3/hr.
What is v0?
v0 by Vercel is an AI-powered UI generation tool that creates production-ready React components and full web pages from text descriptions or image references.
