AI Act Model Cards
Transparency documentation for every AI model served through Nextbit's API, published in accordance with the EU AI Act.
Introduction
Regulation (EU) 2024/1689 (the "AI Act") requires providers of general-purpose AI models to publish certain information about each model's identification, architecture, license, training data, and systemic risk profile, under Article 53(1)(c) and Article 53(1)(d).
Nextbit256 S.L. serves the models listed below via its inference API but did not develop or train any of them. Each model card below is a summary of the publicly available documentation published by the original model developer, together with Nextbit's own license verification and systemic risk assessment. Where information has not been published by the developer, the card says so explicitly rather than estimating or omitting it.
Model cards are transcribed faithfully from their source documentation and are not marketing material.
