Why these criteria?

The three weights that move the ranking most for lawyers.

Reasoning (×1.5)

Legal analysis hinges on multi-step argumentation, statutory interpretation and edge-case spotting — raw reasoning quality matters more than anything else.

Long context (×1.4)

Contracts, case files and discovery sets routinely run hundreds of pages; models with large context windows avoid lossy summarisation.

Document analysis (×1.4)

Clause extraction, redlining and citation lookup require precise structured reading — not creative generation.

Lawyers FAQ

Is ChatGPT GDPR-safe for law firms?+

ChatGPT Team and Enterprise tiers offer data-processing addenda and EU data residency, and OpenAI does not train on Team/Enterprise data by default. The free and Plus tiers are not appropriate for client-confidential matter without further safeguards. Always check your jurisdiction's bar guidance.

Can I use AI for client-confidential work?+

Yes, with the right tier and configuration. Stick to enterprise/team plans with no-training defaults, signed DPAs, and SSO. For privileged matter, consider deployments running in your own VPC (Azure OpenAI, AWS Bedrock, Vertex AI) or specialised legal tools like Harvey.

Which model is best for contract review?+

Models with strong reasoning and 200k+ token context windows tend to win. Today the top of this ranking reflects exactly that — see the #1 spot for the current pick.

Are these rankings independent?+

Yes. The score is fully algorithmic and re-weighted for legal use cases. Some outbound links are affiliate, marked rel="sponsored". No vendor pays for placement.
