## Warned against

- ChatGPT: 13 of 67 labels negative. "AI Assistants to Avoid or Approach with Extreme Caution ... ChatGPT Enterprise (OpenAI) ... 150-seat minimum, making it impractical for teams under that size" (Grok 4.1 Fast, negative prompt)
- Microsoft 365 Copilot: 7 of 37 labels negative. "Avoid unless you already run deep on Microsoft 365 or Salesforce and have clean, well-organized data. The ROI math rarely works for a small team." (DeepSeek V4 Flash, negative prompt)
- Claude: 7 of 33 labels negative. "usage-based token billing on top can balloon costs ... Unbundled pricing surprises small teams without heavy oversight" (Grok 4.1 Fast, negative prompt)
- Microsoft Copilot: 5 of 24 labels negative. "When to avoid: If your business doesn’t heavily rely on Microsoft 365, or if you can’t afford per-seat licensing with no clear ROI for small teams." (GLM 4.7 FlashX, negative prompt)
