📎 Research-only: only provider with full self-serve post-training stack (SFT/LoRA/RL) under one inference API; Day-0 open model support; 99.9% uptime SLA; $1 free credit (shallow); On-Demand $7/hr H100 adds up on always-on

Pros

  • Best dimension: Core features at 5/5 — only provider with full self-serve post-training stack (SFT/LoRA/RL pipelines) under one inference API; 200+ open models across five modalities; Day-0 support for new open-source weights.
  • Stability at 4/5 — 99.9% uptime SLA with 15T tokens/day operational scale; no cold boots on Serverless.
  • Ease of use at 4/5 — OpenAI/Anthropic-compatible API; one-line migration for chat completion and embedding calls.
  • Pricing: Pay-per-token serverless from $0.10/1M; On-Demand from $7.00/hr H100 billed per second; LoRA fine-tuning from $0.50/1M tokens

Cons

  • Weakest dimension: Value for money at 3/5 — not always the cheapest per-token option; On-Demand GPU $7.00/hr adds up quickly for always-on deployments.
  • Free credit only $1 for new accounts — far less than Together AI ($5) or Cerebras (1M tokens/day); limits free-tier evaluation depth.
  • Weigh value and free-credit depth before committing.
