Model and vendor registry
Where the intelligence comes from, and what happens when it goes away
12 models from 7 suppliers, each with its provenance, its data boundary, the towers that call it and the agents that depend on it. more
Health
Concentration, currency, substitutability, exposure
Each reading names the weakest record underneath it rather than averaging it away.
How it runs
Suppliers, then models
A supplier row is a commercial exposure. more
Suppliers
7 suppliers · concentration is share of estate inference calls, not share of spend
Contract Enterprise agreement, committed annual volume · term ends Mar 31, 2027
Reprice notice 90 days · exit notice 90 days either side
Unit price is fixed for the committed volume band until the term ends. Anything above the band is billed at list, and list has moved twice in the last eighteen months. There is no protection at all on a successor model: when a model is retired, the replacement is priced fresh.
Six of every ten inference dollars go to one supplier. more
Models: Abraxas Reason 4 · Abraxas Reason 3 · Abraxas Swift 2 · Abraxas Embed 3 · Abraxas Vision 2 · Abraxas Reason 2
Contract Enterprise agreement, pay as you go above a small floor · term ends Dec 31, 2026
Reprice notice 30 days · exit notice 30 days either side
Thirty days of notice on any list change and no committed band. Cheap to leave, cheap to be repriced against.
Held deliberately as the second source. more
Models: Corvid Counsel 2 · Corvid Embed 1 · Corvid Counsel 1
Contract Permissive licence, no vendor contract
Reprice notice Not applicable · exit notice None
There is no price to protect. The cost is the compute we rent to serve the weights, which is a Nimbus line item, not a Helix one.
The weights are held on our own storage. more
Models: Helix 70B Instruct · Helix 8B Instruct · Helix Guard 3
Contract Committed spend agreement with reserved capacity · term ends Jun 30, 2027
Reprice notice 60 days on uncommitted capacity · exit notice 120 days
Reserved capacity is fixed for the term. Burst capacity is at spot and has ranged 1.4x to 3.1x reserved in the last six months.
The serving stack is containerised and has been rebuilt from scratch on a second provider in a lab, but never under load and never with production data.
No model in the registry maps to this supplier.
Contract Annual subscription by index size · term ends Jan 31, 2027
Reprice notice 60 days · exit notice 60 days
Fixed for the term at the contracted index size. Growth past the size band reprices the whole subscription, not the increment.
Index contents are exportable as JSONL with vectors intact. more
No model in the registry maps to this supplier.
Contract Annual subscription by ingested event volume · term ends Nov 30, 2026
Reprice notice 30 days · exit notice 30 days
None beyond the current term. Event volume has grown 3.2x since the contract was signed and the renewal will be quoted against the new volume.
Traces are the evidence trail behind every automated decision. more
No model in the registry maps to this supplier.
Contract Enterprise agreement bundled with the wider IT estate · term ends Mar 31, 2028
Reprice notice 90 days · exit notice 180 days
Per-identity price fixed to the end of the term.
Standard OIDC. Group and entitlement mappings are held in our own configuration, not in the provider, so a change of provider is a project rather than a rebuild.
No model in the registry maps to this supplier.

Substitution path
Abraxas Reason 4 — tested

Deliberate second source. Thirty days of reprice notice is short, but the workload is portable inside that window.

EVS-ADVERSARIAL
Substitution path
No substitute identified
No substitute configured. Every agent in the estate calls it and there is no second implementation of the guard path, so a failure here fails the whole estate closed rather than open.

What to pick up
What is unsafe right now
Every row here is a dependency the estate cannot currently move off inside the notice period on the contract above it.

Against the written intent
Does the multi-supplier position hold in the traffic
The stated position is that no single supplier should be able to stop the estate. more
Position
No single supplier carries more than half of estate inference calls.
Not holding — Abraxas Foundry carries 61%.
Position
Every model in live use has a substitute that has been run at least once.
Not holding — 8 of the 10 models in live use have a substitution that has actually been run. 1,803 agents sit behind one that is untested or absent.
Position
Enterprise content is never used to train a supplier model.
Holding on every contract in the registry.
What this page is, and what it is not
A security certification and a penetration test are organizational attestations. more
The same applies to a model card. The provenance, the data boundary and the training terms below each model are transcribed from a supplier contract; nothing here re-derives them, and no independent party has verified that a supplier honors them. Call volumes and weekly cost are computed from the modeled estate rather than metered from a billing feed. Read this registry as the inventory of what the estate depends on, not as assurance that those dependencies behave as written.
Actions
What is waiting on a person
Model supply is a dependency like any other. more
live models have no named substitute
A substitute is a second model the same work has been run against. more
model has a retirement date announced
The vendor has published an end of life. 168 agent bindings sit on those models. more
substitute is named but never run
A substitute that has not been evaluated is an intention, not a fallback. more
vendors are not assessed
No completed assessment on file. The platform still calls them.
Operations
What this desk is allowed to start
A surface that only reports is not operable. more
Trigger and bound
12 models from 7 vendors, 9 generally available and 2 already retired. 3 run in our own tenancy. more

Is policy and strategy coming to fruition
Whether the written intent is holding here
Not holding. The register is honest about what we run and silent about what we would run instead.
Not holding on the record
The written intent is that no single vendor can hold the estate hostage. more
