# Mithril — `com-kotobalabs`

**Empower those who protect. / 守る人に、力を。**

Open-weight models of [**Mithril**](https://mithril.fund) — specialized LLM inference for verified white-hat researchers.

Mithril (formerly *Kotoba Cloud*) is operated by **Kotoba Labs Inc.** The handle `com-kotobalabs` is unchanged, so existing model IDs keep working.

このページは [**Mithril**](https://mithril.fund)（旧 Kotoba Cloud）のオープンウェイトモデルを公開する organization です。運営は **Kotoba Labs Inc.** です。

## 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**.

## Mithril research platform

[mithril.fund](https://mithril.fund) is where these weights are put to work. Identity-verified researchers walk a fixed workflow — **INVESTIGATE → VALIDATE → REMEDIATE** — from reviewing authorized code to a responsible-disclosure fix.

- **Access:** Passkey + post-quantum (ML-DSA-65) auth, Stripe Identity eKYC, AML/CTF screening, per-engagement scope confirmation.
- **Free research allowance:** 1,000 requests/day, up to 32,768 output tokens per request. Beyond it: plans from $20/mo or prepaid AI credits from $10.
- **Supply chain:** signed releases (Ed25519 + ML-DSA-65), distributed over content-addressed IPFS/CID.

## 📚 Open data — [knowledge.mithril.fund](https://knowledge.mithril.fund)

A free public catalog of security datasets, served from the edge. **No account, no key.** Every file is CORS-open and supports HTTP Range, so duckdb and pandas read it directly.

- **NVD CVE 2.0** full history (1999–today) as yearly Parquet, with CVSS 4.0/3.1/3.0/2.0, CWE and CPE counts — daily.
- **CISA KEV** and **FIRST EPSS** exploit-probability scores — daily.
- **MITRE CWE** (weekly) and **MITRE ATT&CK Enterprise** STIX bundle (weekly).
- Row counts, byte sizes and sha256 are published in [index.json](https://knowledge.mithril.fund/index.json) and per-dataset `manifest.json`.

```sql
SELECT id, cvss31_sev
FROM read_parquet(
  'https://knowledge.mithril.fund/nvd/parquet/nvd_cve_*.parquet')
WHERE cvss31_score >= 9.0;
```

## 🗂️ Graph & Ontology database — [graph.mithril.fund](https://graph.mithril.fund)

The Knowledge Graph & Ontology database of Mithril (formerly the Kotobase graph plane). Tenant-isolated graphs of datoms over immutable IPLD snapshots; content identity is a CID.

- **Query languages:** Datalog (Datomic-shaped EDN), Cypher, SPARQL, Gremlin bytecode, and bounded read-only SQL.
- **Ontology:** every entity is tagged with an ontology type; the workbench inspects observed attributes and types.
- **For agents:** an MCP server at `graph.mithril.fund/mcp`, and an HTTP API at `api.mithril.fund/v1/database`. Writes need an explicit Biscuit capability, not just a session cookie.
- **Start free**, no credit card: create a workspace and open a database right away.

---

## 🧪 App Studio — [app.mithril.fund](https://app.mithril.fund)

Build and deploy bounded ontology applications: author a typed Mithril Form, then run one finite agent loop — OWL inference → SPARQL selection → SHACL validation → compile → conformance test → content-addressed deploy.
