AI inference, ten ways.
Each one shipped.

We don't ship anything that hasn't passed the same eval suite as the hosted baseline.

01 /

AI Infrastructure Migration

From OpenAI, Anthropic, Together, Replicate, Bedrock, or Vertex onto your own GPUs in your VPC. We design the cutover plan, run shadow traffic, validate eval parity, and stage the rollout behind feature flags so customers never notice.

Duration
6-14 weeks
Typical outcome
median ~60% inference cost saved
02 /

Inference Optimization

Speculative decoding, paged attention, INT8/FP8 quantization, kernel fusion. We profile your actual production traffic, then commit to a target, p95 latency, tokens/sec, $/1M, and ship until we hit it.

Duration
4-8 weeks
Typical outcome

Custom CUDA / Triton kernels

When the off-the-shelf doesn't fit. Fused ops for unusual attention variants, sparse MoE routing, novel KV cache layouts, custom samplers. Profiler-led, math-first.

Duration
3-10 weeks
Typical outcome
1.4-6× kernel-level speedup, typical

GPU Hardware advisory

What to buy, when to rent, when to colo. We've sized clusters from a single workstation to multi-thousand-GPU H200 fleets. Vendor-agnostic, we have no resale agreements.

Duration

Inference Scaling & Autoscaling

Multi-region deployment, request routing, cold-start mitigation, traffic shaping. Built on what you already run, k8s, Nomad, bare metal, not a proprietary platform.

Duration
4-6 weeks
Typical outcome

RAG Performance Tuning

End-to-end retrieval pipelines that don't blow your latency budget. Embedding model choice, vector store sizing, hybrid retrieval, reranker placement, batching across stages.

Duration

Model Distillation & Quantization

Take a 70B teacher down to a 7B student that holds eval parity within tolerance. INT4/INT8/FP8, GPTQ, AWQ, LLM-QAT, whatever the hardware likes best.

Duration

On-prem / VPC Deployment

Air-gapped, ITAR, HIPAA, EU data residency, whatever your compliance regime requires. We deploy and document everything; your team operates it.

6-10 weeks

SRE & On-call (limited)

Three-month bridge contracts only. We share on-call rotation while your team learns the system. Then we leave, on schedule.

Duration
up to 12 weeks
Typical outcome

Cost audit

Written diagnostic. We inspect your stack, model your spend, and tell you in writing how much you'd save self-hosting. Refundable against the engagement that follows.

methodology

How we measure.

Real workloads, real traffic

Numbers from actual production rollouts, sampled across the day. Not synthetic stress tests.

Eval parity before perf

We don't quote a speedup unless the model passes the same eval suite as before, within the agreed tolerance.

Hardware disclosed

Every benchmark says exactly which SKU, how many, what interconnect, and what the host OS was running.

Failures included

We publish the cases where it didn't work, too. The interesting margin is in what doesn't optimize.

Not sure which one you need?

The cost audit usually answers it, refundable against whatever comes next.
