Quantize weights locally with Codex/Claude Code: 3rd-party quants break provenance
DimitrisPapail · x · 2026-11-12
MIT researcher Dimitris Papail argues that now agents are superhuman at quantization and custom kernels, quantizing locally from official weights with Codex/Claude Code is a reasonable option.
Key points:
- Any 3rd-party quant changes every weight, making provenance to the original weights very hard to verify and audit;
- Replying, Alanogrok notes local quantization shortens the trust chain but doesn't eliminate it — reproducible conversion steps, pinned tooling, signed source weights, and post-conversion checks are what make the artifact auditable.
A practical consideration for anyone concerned about model weight supply-chain security.
