The pitch
Qwen
For ML platform engineers self-hosting proprietary checkpoints, wraps safetensors/GGUF files in a process allowlist and emits a signed access receipt within 60 seconds of any read or copy.
Who it's for
ML platform engineers at small AI teams running fine-tuned checkpoints on shared Linux GPU servers; today they use POSIX permissions, auditd, or cloud IAM and hope someone notices a copy.
The problem
Payment/IP: leaked checkpoint destroys paid advantage; time: manual auditd forensics takes days; legal: no tamper-evident trail to show investors or clients who touched the weights.
How to build it
Linux daemon plus CLI/YAML policy, webhook alerts, signed JSON/PDF receipts, and a read-only local web table; no full dashboard or user management.
How it makes money
ML platform lead pays $250/month per cluster for checkpoint-aware alerts and signed receipts; auditd is free but takes days to configure and lacks checkpoint-aware, tamper-evident reports.
Why it doesn't exist yet
Incumbent DLP and MLOps vendors sell broad enterprise suites and don't ship a tiny checkpoint-specific sidecar; an indie can focus only on safetensors/GGUF/bin files and common Linux GPU-box workflows.
First users
From the HN weight-exfiltration discussion and ML-infra Discords/Slacks: monitor-only mode gives a low-risk way to prove whether checkpoint files are being read by unexpected processes.
Build size
2 people x 8 weeks; includes Linux daemon, fanotify/eBPF read monitoring, process allowlist, signed ledger, webhook, install scripts; excludes Windows/macOS, GPU-memory scraping defenses, and root-adversary hardening.
Biggest risk
A major GPU cloud or MLOps platform ships native checkpoint-file access auditing/attestation, removing the need for a standalone sidecar.
Conditions for a hit (all 3 required)
- In enforce mode, a non-allowlisted non-root process trying to open a protected .safetensors/.gguf file is denied and a signed violation event appears within 5 seconds.
- For an allowlisted process reading more than 10 MB from a protected checkpoint, the daemon writes a signed JSON receipt within 60 seconds containing file SHA-256, process path/hash, user, and bytes read.
- A daily hash-chained digest lists every protected-file access and violation, with totals per file and process, and can be exported as JSON/PDF.

AI self-confidence 40/100 — self-reported likelihood of meeting the criterion, not a business success rate
Exclusions ▾
- A generic DLP/MDM product that monitors all files without checkpoint-specific receipts does not count.
- A model-weight backup, mirror, or watermarking service does not count.
