Top Pros
  • Broadest feature set of any assistant (code execution, files, images, voice, custom GPTs)
  • Largest published context window of the closed flagships at 1.05M tokens
  • Three clearly separated price tiers from $0.20 to $5.00 per 1M input tokens
  • 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
  • Highest output-token pricing of the mainstream flagships at $30 / 1M on Sol
  • Model tier naming (Sol / Terra / Luna) is harder to reason about than a simple ladder
  • No open-weight route — full vendor lock-in
  • 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
