For developers

  • Claude Code v2.1.212: try the change on one real task before switching defaults.

  • OpenAI Codex CLI rust-v0.145.0: try the change on one real task before switching defaults.
  • Zed AI v1.13.1: try the change on one real task before switching defaults.
  • Goose v1.44.0: try the change on one real task before switching defaults.
  • Keep a second assistant ready so vendor downtime is not career downtime.

For teams

  • Claude Code: review security/pricing/breaking notes before org-wide enablement.
  • OpenAI Codex CLI: review security/pricing/breaking notes before org-wide enablement.
  • OpenAI Codex CLI: review security/pricing/breaking notes before org-wide enablement.
  • Zed AI: review security/pricing/breaking notes before org-wide enablement.
  • Goose: review security/pricing/breaking notes before org-wide enablement.
  • Treat assistants as a portfolio; standardize only after a pilot.

What to ignore

  • Nav/marketing page scrapes without versions
  • Duplicate changelog + release entries for the same version
  • “Stale” assistants until source health recovers (see Compare)
