Pros & Cons
Vellum AI
- Genuine repositioning toward conversational agent building lowers the barrier for less LLMOps-experienced teams
- Free plan provides real hands-on testing with 50 monthly credits and a 20-document knowledge base
- Visual workflow editor still supports fine-grained control (LLM calls, code, conditionals, retrieval) for advanced users
- Pro tier at $89/seat/month can add up quickly for larger teams
- January 2026 repositioning toward conversational agent building may not suit teams wanting a purely code-first LLMOps tool
- Enterprise pricing requires custom sales engagement with no public figures
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
