What changed for this shortlist

Impact score: 95

Estimated monthly cost: $100

ChatGPT

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.
