Provider comparison

Together AI vs Vast.ai

Together AI

Together AI provides blazing-fast hosted inference for open-weight models including Llama 3.1 (8B through 405B), DeepSeek V3, Qwen 2.5, and Mistral - all at prices far below closed-model APIs. Its optimized serving infrastructure and free tier for experimentation make it the go-to platform for teams that prefer open models without self-hosting overhead.

Vast.ai

Vast.ai is a decentralized GPU marketplace where host operators list idle accelerators at market-driven prices - often the lowest spot rates anywhere. The trade-off is variable reliability, no compliance certs, and community-grade support; ideal for cost-sensitive experimentation, fine-tuning, and batch inference where occasional interruption is acceptable.
