Changelog

Cypris changelog

Every tracked product and technology change at Cypris, dated and sourced. Each entry names the change, its impact and the live source it was graded from.

Product and technology changes only. Funding rounds, valuations, partnerships and awards are excluded, and an acquisition appears only where there is direct product impact. Every entry cites a live retrieved source. Changes to the index's own records are not changelog material; a corrected record carries its own dates.

Model / architecture

Google's Gemini 4 Argon is now in the model picker in Cypris Q, Cypris's agentic research layer. Cypris says its internal testing found Argon beat Gemini 3.1 Pro on every question it tried and matched Claude Opus 5.5 at slightly lower cost, with answers about three times longer. It recommends Argon for white space analysis, competitive intelligence and technical landscape research.

Buyer relevance. IP teams running landscape work can pick a slower, deeper model and know which provider it comes from. The comparison is Cypris's own testing with no published method, so accuracy inside Cypris is still unproven.

The AI Legal Index is an editorial reference. It is not a regulatory body, not a law firm, and nothing published here is legal advice or a recommendation to retain or avoid a vendor. Records are verified against published sources, bar guidance and public court records. Where a record reads not addressed, the material was not located in public sources on the date shown.
