01 / model evidence
Exact checkpoint profiles
0 measured-supported profiles. A named model appears as supported only after the exact checkpoint, runtime, deployment and limits have a reproducible benchmark record.
Current boundary
Kimi K3 is shown only as a calculated capacity candidate. The rack exists for facility-scale throughput and concurrency, neither of which has been measured here; weight fit alone does not justify this platform.
- Repository state
- Repository state retrieved 2026-07-28; pin an immutable commit before deployment
- Licence
- Licence must be rechecked and recorded before deployment
- Weights
- Official repository MXFP4 checkpoint; MXFP4 weights and MXFP8 activations
- Dated artifact total
- 1,560,936,091,448 bytes across 96 safetensors files
- Documented model context
- Up to 1,048,576 tokens in the model specification
- Runtime
- No versioned runtime, container, driver or CUDA profile validated
- Candidate deployment
- 72 GPUs; tensor and pipeline parallelism not yet fixed
- Tested limits
- Context, input, output, batch and concurrency are all unmeasured
GB300 NVL72's documented 20TB aggregate GPU memory is a capacity candidate for this checkpoint. Its commercial purpose is rack-scale throughput and concurrency, neither of which is measured here; checkpoint fit alone does not justify the platform.

- Pricing is quote-only.
- 20TB is aggregate rack accelerator memory and not a generic one-process promise.
- Aggregate GPU memory is not one universal memory pool.
- No model, speed, context, concurrency or multi-GPU efficiency promise exists without a controlled fit profile.
- Rack, electrical work, UPS, cooling, cabling, colocation and on-site installation require a separate scope.
Do not buy this route when
- Kimi K3 weight fit alone is the requirement; HGX B300 is the more proportionate capacity candidate.
- The buyer lacks the liquid cooling, power, data-centre and authorised support infrastructure.
- A referral/channel project and hosted capacity do not pass commercial comparison.
Inspect the evidence behind Frontier Rack 20TB.
The system view shows the selected hardware reference where available. Technical diagrams explain memory, data boundaries, queues, power and handover. The final bill of materials and workload test confirm the ordered system.
Software and security
The usable product is more than the chassis.
The final stack stays deliberately small. Versions, licences, access and recurring ownership are recorded so the customer is not left with an opaque collection of containers.
Software baseline
- Ubuntu LTS on a recorded operating-system version
- NVIDIA driver, CUDA components and container support validated for the ordered hardware
- Docker Engine and NVIDIA Container Toolkit
- One primary model server selected from Ollama, vLLM, SGLang, TensorRT-LLM or llama.cpp for the accepted workload
- Open WebUI or another reviewed browser interface
- Named authentication, TLS and reverse-proxy approach
- GPU, node and service monitoring with an agreed log-retention period
- Pinned versions, a software bill of materials and a model source and licence record
Security ownership
- GPU RIGS baseline
- Initial operating-system state, named administrator handover, host firewall baseline, agreed access route, secrets transfer and documented update state.
- Customer or contracted operator
- User lifecycle, network and VPN policy, backups, monitoring review, patch approval, incident response, data governance and lawful use.
- Shared before acceptance
- Model and software licence checks, retention and logging choices, recovery test, acceptance criteria and a named owner for every recurring task.
Local infrastructure can reduce disclosure to external AI APIs. It does not automatically make the service secure, accurate, confidential or UK GDPR compliant.
Testing and acceptance
The evidence pack is part of the machine.
Performance is confirmed against the accepted workload, exact build and disclosed test conditions. No throughput, latency or quality figure is claimed before that test.
- 01
Record the final bill of materials, serial numbers and firmware versions.
- 02
Run at least 24 hours of GPU, CPU, memory and storage stress testing.
- 03
Capture temperature, fan, error, health and wall-power evidence under the agreed load.
- 04
Test cold boot, restart and the available remote-management route.
- 05
Check drive health, network throughput and the container and GPU runtime.
- 06
Run model and workload smoke tests against the written acceptance set.
- 07
Record any measured speed only with the model, quantisation, context, concurrency and runtime disclosed.
- 08
Test an agreed fault or recovery route and provide the resulting handover record.
What is not claimed today
No fixed users, tokens per second, latency, model size, accuracy, availability, savings or marketplace contribution is stated without the missing configuration and test conditions.
See how systems are testedCommercial reality
Tax and spare capacity are supporting questions.
Neither belongs in a guaranteed saving or payback claim. The purchase must stand on the accepted workload, control case and operating plan.
Finance, VAT and capital allowances
- The displayed figure is for a complete GPU RIGS private AI deployment, not unconfigured hardware. The final written quotation confirms the exact specification, delivery, warranty and accepted workload scope.
- Prices exclude VAT. VAT recovery depends on the buyer, its taxable activities and the normal evidence rules.
- Qualifying equipment may be plant and machinery for capital-allowance purposes. The buyer's accountant decides eligibility and timing.
- A third-party lease or hire-purchase route may be explored after partner validation and credit approval. GPU RIGS is not presented as a lender.
- There is no generic capital-gains advantage and no automatic research and development relief because the equipment supports AI.
Optional idle capacity
- Marketplace mode is off by default and is excluded from the purchase case.
- A separate environment, no customer data mounts, network controls and a local kill switch would be required.
- The customer, insurer, supplier warranty and marketplace terms must permit the intended use.
- Vast.ai, Render, Golem and direct batch work do not guarantee acceptance, demand, rate or income.
- Any dated estimate must identify its source date; a pilot must report achieved utilisation, fees, electricity, cooling, faults and operator time.
Limits and alternatives
A good specification leaves room for “no”.
The fit check can recommend a smaller system, hosted service, hybrid route, custom build or no purchase. That is preferable to making this package carry a workload it has not proved.

Consider this routeQuestions answered
Frontier Rack 20TB questions that affect the order
The written quotation and acceptance plan confirm any price, specification, warranty or workload assumption discussed below.
Does Frontier Rack 20TB provide 20736GB as one memory pool?
Only a single-GPU system provides its stated GPU memory on one card. Multi-GPU totals are aggregate physical capacity; usable sharding depends on the exact model, runtime and topology.
Which models are supported?
Only models with a reproducible fit profile are listed as supported. Capacity candidates are labelled separately; a memory calculation alone is not a support claim.
Is the displayed price final?
No. An indicative price is a transparent planning value based on dated inputs. Quote-only platforms and the final order require a current supplier quote, accepted bill of materials and delivery scope.
Can spare capacity earn income?
It may be evaluated as an optional isolated secondary use. Marketplace acceptance, utilisation, rates, fees, energy and income can change and are never guaranteed or included in the purchase case.
Prepare the next decision
Specify the work before the parts.
Record the workload, data boundary, users, site and acceptance test. No confidential documents or credentials are needed for the first brief.
Package figures exclude VAT and cover the stated GPU RIGS deployment scope. Every final order requires a written quotation confirming the specification, availability, delivery, warranty and workload acceptance plan.
