Kotoba Labs — com-kotobalabs

A model lab for white-hat security.

🔗 kotoba.cloud

Kotoba Labs publishes open-weight language models tuned for authorized security research. Our models power Kotoba Cloud — “Empower those who protect” — and are part of the Kotoba ecosystem for safe, AI-generated software.

Purpose

— Defensive by intent. Models help auditors and white-hat researchers review code, validate vulnerabilities, and prepare fixes.

— Honest, reproducible builds. Every model documents what changed, the method, the base model, and the serving footprint.

— Hardware-real optimization. Weights are quantized to what the target GPU actually runs — e.g. NVFP4 for NVIDIA RTX PRO 6000.

Kotoba Cloud

Kotoba Cloud is where these weights are put to work: identity-verified researchers walk a fixed workflow — INVESTIGATE → VALIDATE → REMEDIATE — from inspecting in-scope code to a responsible-disclosure fix. “One person’s discovery becomes a community’s strength.”

— Passkey + post-quantum (ML-DSA-65) auth, Stripe Identity eKYC, AML/CTF screening, per-engagement scope approval.

— Free tier for verified researchers: 1,000 requests/day, up to 32,768 tokens.

— Signed releases (Ed25519 + ML-DSA-65), distributed over content-addressed IPFS/CID.
