Mini Case Story: Legal Copilot Evaluation

A law firm tested all three models.

  • GPT-5 excelled at deep reasoning.
  • Claude 3.7 minimized compliance risk.
  • Llama 3.2 enabled in-house hosting.

The Debate: Closed vs Open Models

  • Closed: Better performance but costly + opaque.
  • Open: Flexible, transparent, affordable.
  • Prediction: Hybrid stacks dominate enterprise AI in 2025.

Action Plan

  1. Benchmark models on your domain tasks.
  2. Balance performance vs cost vs compliance.
  3. Consider hybrid OSS + closed deployments.
