Positioning

"Denpex is the reliability control plane for AI training infrastructure."

Not

  • Not "a Python script that diagnoses GPUs".
  • Not "an LLM that hallucinates a root cause."
  • Not "a metrics vendor that lists counters without context."

Yes

Denpex is the seven-layer stack that:

  1. Wraps training (denpex_lite) — stdlib Python, 397 signatures.
  2. Hosts telemetry — agent + GPU + fabric + storage collectors.
  3. Instruments frameworks — per-layer hooks + SDC canary.
  4. Correlates & diagnoses — deterministic rules + RAG.
  5. Predicts — Welford / Weibull / peer-relative drift.
  6. Auto-remediates — K8s + SLURM state machine, policy tiers.
  7. Runs in your tenant — multi-tenant, air-gapped, FIPS, SOC2.

What We Don't Claim

Per docs/capability-matrix.md#what-is-never-claimed-any-tier:

  • "Detection latency under 1 ms" without published measurement.
  • "Zero overhead" — measured overhead is bounded at < 1.5 % per docs/agent-overhead-benchmarks.md.
  • "100 % SDC detection" — limits are documented in docs/silent-corruption-detection-limits.md.
  • "Compatible with anything not on the matrix" — see each supported-*-matrix.md.

Pricing Tiers

See docs/pricing-architecture.md.

  • Free (0–8 GPUs, 7 d retention): Denpex Lite only.
  • Team ($415/mo, 8–64 GPUs, 30 d retention): + premium signatures.
  • Scale ($2,495/mo, 256–1,024 GPUs, 90 d, multi-cluster): + Host Agent + RBAC.
  • Growth ($4,580/mo, 4,096+ GPUs, 1 y, multi-cluster): + RAG + K8s/SLURM remediation + FedRAMP.
  • Air-gap appliance (16k+ GPUs, customer VPC): custom contract.

Where Denpex Ships

  • SaaS control plane — single-region primary (WNAM) with globally-replicated reads. Multi-region active-active data residency is available only in the self-hosted control plane and air-gapped appliance, not the SaaS tier (see docs/operations/SLA.md).
  • Self-hosted control plane — Helm + bare-metal/RHEL/Ubuntu.
  • Air-gapped appliance — single signed tarball, HSM-rooted KMS.
