Top Pros
  • V4 Flash at $0.14 / 1M input is roughly 35x cheaper than the closed flagships
  • MIT-licensed open weights allow self-hosting with no commercial restrictions
  • 1M-token context at open-weight pricing
  • Inline citations on every answer, which general assistants still do inconsistently
  • Model choice across OpenAI, Anthropic and Google on one subscription
  • Best-in-class for search-grounded research tasks
Main Cons
  • No vision input on the V4 line
  • China-based hosting raises data-residency questions for regulated buyers
  • Thinner enterprise support and SLA story than US vendors
  • You are paying a margin on top of the underlying model providers
  • Weaker than the native assistants at long-form generation and coding
  • Model routing is opaque — you don't always know what answered
