ChatGPT

Impact score: 95

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.

ChatGPT

Impact score: 95

ChatGPT becomes easier to defend as the broad default when a team wants one OpenAI ladder spanning chat, coding, and API-adjacent work instead of a narrower assistant seat.

ChatGPT

Impact score: 80

Teams should no longer read Codex only as a developer coding add-on. For mixed-role teams, ChatGPT Business and Enterprise now have a stronger case as a workflow standardization layer for analysts, marketers, operators, product teams, and engineering-adjacent work. Pure IDE-native coding buyers should still compare Cursor, GitHub Copilot, and Claude Code separately.

ChatGPT

Impact score: 80

ChatGPT
