# German lab Empero AI announces Manta, claiming a model that reads 100 million tokens in one prompt (unverified, waitlist only)

Empero AI, a small independent lab in Germany, announced Manta on Nov 6, 2026 on X (~460k views), saying it 'reads a hundred million tokens in one prompt'; its site says it can hold 'essentially an infinite context'. No architecture, benchmarks or pricing were published and access is a waitlist research preview, so the claim is unverified.

## Key facts
- Claim on X: 'Manta reads a hundred million tokens in one prompt'; website: 'essentially an infinite context'
- No paper, benchmark, architecture or independent test at announcement
- Access: research preview for a small group via waitlist; no public release date

## What happened

Vendor announcement only. Re-check if benchmarks (e.g. long-context retrieval tests) or independent access appear.
