Teams comparing ChatGPT against Claude, Gemini, or specialist coding tools should treat GPT-5.5 as the current capability baseline. ChatGPT Business is more compelling for mixed-role teams because GPT-5.5 Pro access, Codex, connectors, and governance can sit in one workspace seat, while API-heavy buyers must model the higher GPT-5.5 token price separately from subscription seats.

Copilot is harder to dismiss as a cheap baseline-only choice now. For GitHub-heavy teams, the platform keeps its governance advantage while gaining a more credible extensibility story.
