The honest brief

Prime Intellect

Pairs a multi-cloud GPU spot marketplace with an open RL training stack — peers typically offer the compute or the training tooling, rarely both.

  • Multi-cloud GPU marketplace
  • Open-source RL stack (prime-rl)
  • 2,500+ RL environments hub
  • Open INTELLECT model recipes
  • Younger than major GPU clouds
  • RL stack targets advanced users
  • Spot capacity varies by provider

Together AI

One stop for the open-model stack: hundreds of open-weights models served plus both LoRA and full fine-tuning.

  • LoRA and full fine-tuning
  • Competitive inference-at-scale pricing
  • OpenAI-compatible API
  • Dedicated endpoints + GPU clusters
  • Open models only, no frontier closed models
  • Less specialized than single-model hosts
  • Throughput varies by model demand
