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

Aider

  • Every AI-made change is a real, revertible git commit
  • Works across multiple files in a codebase, not just single-file edits
  • Open-source and not locked to a single AI model provider
  • Requires comfort with the command line rather than a graphical IDE experience
  • No built-in chat sidebar or visual diff review the way some IDE-integrated tools offer
  • Users need to bring their own API key for the underlying AI model
