Pros
  • Zero-ops GPU access
  • Python-native
  • Auto-scaling
  • Honest pay-per-second pricing
  • Drop-in OpenAI-compatible proxy makes data capture trivial
  • Meaningful cost/latency wins vs. frontier models on narrow tasks
  • Now backed by CoreWeave GPU capacity post-acquisition
  • Handles the full pipeline from logs to hosted fine-tuned inference
  • RL-for-agents product targets multi-step tool-using workflows
Cons
  • Cold start latency on big models
  • Bills can surprise at scale
  • Not open source; you depend on their managed platform
  • Only worth it once you have real production LLM spend to distill
  • Post-acquisition roadmap tilts toward enterprise infra customers
