GPT‑6 Astra Law, explained.
GPT‑6 Astra Law is designed for eligible law firms piloting source-linked legal research, document analysis and drafting with firm instructions and approved tools. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.

Run anonymised UK matters against the firm's authoritative research baseline. Score jurisdiction fit, primary-authority recall, proposition accuracy, currency and negative treatment, unsupported claims, reviewer minutes, permissions and complete cost per accepted output.
No launch-day score.
HubAI will publish a score only after the same representative tasks have been run against current alternatives. Vendor benchmarks are not treated as an editorial rating.
Cost reality
The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.
Budget for the result, not the plan badge.

What to check before adoption.
Do not place confidential, personal or rights-restricted material into GPT‑6 Astra Law until your organisation has reviewed its current terms, retention settings and account controls. AI output can be plausible and still wrong; regulated, financial, legal and employment decisions require qualified human review.
