Key figure: The global average cost of a data breach was $4.44 million in 2025 (IBM, Cost of a Data Breach Report 2025).
This cybersecurity news report card grades 7 major AI vendors A–F on disclosure labeling, data use, and compliance posture in 2026. See who earns trust and who fails it.
Each vendor gets A–F grades across disclosure labeling, training-data practices, and compliance transparency, based on public terms and documented 2026 behavior. The methodology is published on the page, so you can check the grading yourself — no black boxes.
A–F grades for 7 major AI vendors on AI disclosure labeling, data-use transparency, and terms fairness. Every grade carries a receipt — a linked public source. Where the record is silent, we say so.

Since Sept 2025, consumer chats (Free/Pro/Max) are retained up to 5 years for training unless users opt out — a sharp shift from the prior 30-day deletion standard. Crypto Briefing
The Aug 2025 consumer-terms update required an explicit data-sharing choice with a September 28, 2025 deadline — but the "Help improve Claude" toggle was on by default. OpenTools AI
Meta's April 2024 policy introduced "Made with AI" labels on detected AI content; renamed to "AI info" in July 2024 after photographers objected to mislabeled real photos. Progressive Robot
Stanford FMTI (May 2024): Meta scored 60/100 — the highest of the majors at the time; the 2025 index measured a drop to 31. FMTI 2025, arXiv
Meta's own Oversight Board found AI labeling inconsistent and detection unreliable (June 2025), calling for human review of flagged content. Progressive Robot
California's SB 942 requires large AI systems to ship watermarking and detection tools for AI-generated content; OpenAI also launched "textGrain" watermarking for ChatGPT text output. Goodwin

OpenAI skipped a system card for GPT-4.1, saying it wasn't a frontier model — transparency documentation now arrives selectively. AI Magazine
xAI launched Grok 4 without publishing system cards — the industry-standard transparency reports — drawing public criticism from OpenAI and Anthropic researchers. Technology Magazine
Grok's data privacy is governed by the broader X platform terms rather than standalone Grok policies, with no transparent usage reporting. DataStudios
INSUFFICIENT DATA — no reliable public record found evaluating xAI's standalone consumer terms, so no grade is assigned. DataStudios
No public disclosure/labeling framework found in the public record; regulators found its data disclosures "totally insufficient." The Hacker News, Jan 2025
Italy's data regulator (Garante) blocked DeepSeek on Jan 30, 2025 after its answers on personal-data collection, sources, purposes, and China storage were deemed "totally insufficient." The Hacker News, Jan 2025
The Garante found no EU representative designation as required by Article 27 GDPR, alongside a non-compliant privacy policy. Diritti Comparati
No. These are editorial grades from Ingenious AI — not official ratings and not a certification. Every grade is anchored to a linked public source, and where the public record is silent the card says INSUFFICIENT DATA rather than guessing.
Disclosure labeling: does the vendor mark AI-generated content so people can identify it. Data-use transparency: is it public how user data is collected and used for training. Terms fairness: are the vendor's policies clear, proportionate, and honestly enforced.
It means no reliable public source was found to evaluate that criterion for that vendor. We would rather mark the gap openly than assign a grade on assumptions.
No vendor yet publishes complete training-data documentation, universal AI-content labeling, and fully fair terms at the same time. Independent research agrees: Stanford's transparency research found no developer near adequate transparency, with the top score at 54 out of 100.
The Transparent AI Index is a broader 12-vendor transparency matrix. This report card narrows the field to 7 major vendors, issues A–F letter grades per criterion, and attaches a verifiable source receipt to every single grade.
