Who Should Upgrade?

  • Enterprise Teams processing legal/technical documents (long context critical)
  • Developers building tools with direct API integrations
  • Cost-Tolerant Projects where native tool use saves engineering overhead

Avoid upgrading if you use GPT-4o for short-context tasks (e.g., customer support) where cost savings outweigh minor efficiency gains.
