The frontier AI that never leaves the building
Opus-class output, behind your firewall, at fixed cost.
Harbor delivers frontier-grade reasoning inside your perimeter, ensuring that client records, contracts, IP, and transaction data never cross into a counterparty's environment.
Enterprise AI forces a choice between capability and control.
Capable, but your data leaves the building.
Client records, contracts, IP, transaction data — everything has to cross into a counterparty's environment to use the best models.
Inside the perimeter, but not smart enough.
Self-hosted models keep data safe, but the quality gap with frontier APIs is wide enough to break business-critical use cases.
A complete frontier-grade stack, deployed inside your perimeter.
Fortytwo Harbor combines specialized models and on-premise compute into one inference system — a drop-in replacement for cloud AI endpoints. Its core architecture replaces single-model output with multi-model consensus.
- STEP 1
Generate
Specialized models each draft a candidate answer in parallel.
- STEP 2
Peer-rank
Models score each other's responses for quality and accuracy.
- STEP 3
Reputation-weighted vote
Strongest answers aggregate into one consensus output.
Frontier output, without the trade-offs.
Opus-class intelligence
Frontier-grade reasoning from a swarm of generalist and specialist models, without leaving your perimeter.
Resilience to prompt injection
A prompt that fools one model is rejected by its peers in the swarm.
Lower hallucination risk
Reputation-weighted voting suppresses confident-but-wrong answers. Outputs reflect what the strongest models agree on.
30% lower TCO
Fixed hardware cost replaces per-token billing. Predictable spend, controlled rate limits, no surprises.
Two ways to run a pilot.
Software license + hardware bundle.
A drop-in replacement for cloud AI endpoints — same interface, zero egress. We deliver and stand up the full stack inside your environment.
Software-only deployment on your hardware.
Same evaluation deliverables, faster setup. Run Harbor on the compute you already operate.

Frequently asked questions.
- What models run in the swarm?
- A mix of open-weight generalist and specialist models, tuned to your domain. We lock the exact configuration with you during the pilot. It's designed to outperform frontier APIs on your workload.
- What hardware does Harbor need?
- Harbor runs on standard on-prem GPU servers. We size the exact footprint with you in the pilot, or ship it pre-configured in the turnkey track.
- How does Harbor stay ahead of frontier models?
- We tune the swarm to your domain and keep refining it throughout the engagement. Harbor is designed to stay ahead of frontier APIs on your workload, not just at launch.
- Does it work with our existing stack?
- Yes. Harbor is a drop-in replacement for cloud AI endpoints. Point your apps to a new base URL to keep the same interface, with no code changes required.
