Pros & Cons

CodeT5

  • Fully open-source under the permissive Apache 2.0 license
  • Historically outperformed OpenAI’s code-cushman-001 on HumanEval despite being open-source
  • Community forks keep the project alive despite Salesforce archiving the official repository
  • Salesforce archived the official GitHub repository in May 2025 — no longer under active first-party development
  • Smaller and less capable than current frontier commercial coding models
  • Requires more technical setup than a ready-to-use commercial coding assistant

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
