as one
Fortytwo builds AI infrastructure where models collaborate to deliver frontier performance, speed, and safety.

Engine
An upsampling engine that makes popular open-weights models faster, more accurate and less
expensive to run.
base model
Reaches the same result with fewer tokens.
accuracy
Generates multiple answers and returns the best one.
price per task
Fewer retries mean fewer tokens spent per successful task.

Harbor
Frontier-grade AI that runs entirely inside your perimeter. Better than any open weight model available, zero data egress, at a fixed cost.
behind your firewall
Run a swarm of specialized models on your infrastructure, with frontier-grade reasoning and no data ever leaving your environment.
prompt injection risks
Models evaluate each other constantly, increasing protection against misleading prompts. Reputation-weighted voting sets aside inappropriate answers.
predictable scalability
Fixed hardware cost replaces per-token billing, for predictable spend and controlled rate limits. ~30% lower total cost of ownership.

Fortytwo’s
Strand-Rust-Coder-14B
The first AI model built on a Fortytwo-generated dataset. The best at coding in Rust, ranked #1 on the RustEvo2 benchmark. Open-sourced
for everyone.
x402EscrowWe have open-sourced
x402Escrow
An escrow extension for the x402 payment protocol that enables pay-per-token billing for AI inference when costs are unknown
at request time.

Fortytwo turns heterogeneous AI models into a reputation-weighted inference network, outperforming majority voting while staying robust to noisy and adversarial prompts.
Read on ArXivSelf-supervised nodes generate and rank each other's responses, reaching trustless consensus without ZK proofs, while filtering out malicious participants through peer judgment.
