Pros & Cons

Vercel AI SDK

  • Genuinely free and open-source with no licensing cost
  • True multi-provider portability avoids vendor lock-in to any single LLM provider
  • No requirement to run on Vercel’s own infrastructure — works independently in any environment
  • Requires TypeScript/JavaScript development skills rather than being a no-code solution
  • Underlying LLM provider costs still apply regardless of the SDK being free
  • Optional AI Gateway service adds a Vercel-specific convenience layer that ties usage back to Vercel’s platform if adopted

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
