Cold-start

Stop paying the cold-start tax on every tenant.

isovert lets tenants safely share one warm model instead of loading per tenant. On a single node, across three transformer families, we measured 90×–1000× cold-start reduction. We're looking for one serving partner to prove it at fleet scale — and capture the saving first.

The cost we remove

The per-tenant load penalty, at scale

isovert changes the shape of the problem: a shared warm model, provable isolation between tenants, and the per-tenant load penalty largely gone.

Serving cost

Every tenant that needs its own model instance burns GPU-hours idling warm — or pays to reload on demand. The bill scales with tenants, not usage.

First-token latency

A cold tenant waits for a full model load before the first token. The usual fix — keeping everything warm — just moves the cost back onto the GPU bill.

The trade-off

Keep everything warm and it is expensive; accept cold-start and it is slow. Either way you are paying the per-tenant load penalty at scale.

What we measured — and what we didn't

90×–1000×, and the caveats that make it credible

One capture per model, on a single node. The spread is large and model-dependent — so here is the full range, each figure with its note, not a cherry-picked headline.

Model family
Cold-start
Qwen
~1000×
Largest observed reduction; heaviest per-tenant load penalty removed.
Gemma
~190×
Mid-range of the observed spread.
DeepSeek
~94×
Lower bound of the measured range.

Scope. Measured on a single hardware configuration, transformer-only — it does not port to state-space models. One capture per model; variance is large and model-dependent. Cross-hardware and fleet-scale are unproven — that is the design-partnership deliverable, not a claim.

The joint-validation offer

A bounded benchmark on your stack

  • A bounded, roughly two-week benchmark run on your serving stack.

  • You set the success bar and the kill criterion up front.

  • A fast, honest no if it does not port to your hardware — the caveats are the point.

  • If it holds, you capture the serving-cost saving before anyone else.

Why safe sharing, not just caching

The saving comes from provable isolation

Caching tricks can warm a model, but they can't let different tenants safely share one — shared model state leaks across tenants. The saving here comes from provable multi-tenant sharing, the isovert isolation core, which is what makes one warm model safe to share in the first place.

That means the cost win composes with a security property your regulated customers already want: per-tenant isolation you can prove, on commodity hardware, with no foreign hardware root of trust.
