  • Near-free API pricing
  • DeepSeek-V3 / R1 are serious models
  • 500+ tokens/sec on Llama/Mixtral — feels instant
  • Custom LPU hardware
  • Great free tier
  • General-purpose agent — research, book, build, analyze
  • Parallel task execution

  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
  • Still hit-or-miss on complex multi-hour tasks
  • Can burn credits fast
  • Can feel overwhelming for non-coders
  • Expensive at scale
Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for speed. When latency is the product, start here.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
