On-prem and open-weight models in regulated, high-security enterprises
Adoption of on-premises and open-weight AI models in financial services, defence and healthcare, September 2023–September 2026: the split between hosted API, private cloud and on-prem deployment, routing and gateway tooling (OpenRouter, LiteLLM, vLLM, NVIDIA NIM), sovereign model providers (Mistral, Cohere, Aleph Alpha) and their government agreements including Cohere and Mistral with the UK Government, and how regulated firms actually use models in high-security environments
Synthesised 2026-09-26
Overview
Nobody has measured the number this report is supposed to lead with. Across six research lanes and roughly 150 sources, no regulator, analyst house or academic team has published a three-way split of enterprise model usage between hosted API, private cloud and on-prem for financial services, defence or healthcare. What exists instead is a set of proxies that point in different directions: Menlo Ventures' enterprise survey shows open-weight share of LLM spend falling from 19% in 2024 to about 11% in 2025, while OpenRouter's platform data shows open-weight and Chinese models taking most routed tokens by early 2026. A CTO who reads either figure as "the on-prem share" is making a category error, because open-weight is a licensing property and on-prem is a location, and a bank can run Llama in a single-tenant Azure region or run Fable through a zero-retention contract.

The defining shift of the past eighteen months is not architectural but political. Between June 2025 and June 2026, sovereignty moved from a marketing frame to a demonstrated procurement risk. The US Commerce Department's June 2026 order forcing Anthropic to disable its Fable 5 and Mythos 5 models for non-US users, and the Pentagon's earlier supply-chain-risk designation of the same company, gave European buyers a concrete precedent for a hosted frontier model being switched off by a foreign government. Fortune reported that event as the strongest single catalyst for European sovereign-AI interest, stronger than any of the memoranda and framework agreements that preceded it.

The supply side responded by consolidating rather than fragmenting. Cohere's acquisition of Aleph Alpha, announced in April 2026 and signed as a definitive agreement in September at a reported valuation near $20bn, folded Germany's national champion into a Toronto-Berlin group. Microsoft's multibillion-dollar July 2026 agreement with Mistral expanded French GPU capacity but left Mistral's inference substantially on Azure. The result is a market where "sovereign" providers depend on North American capital and hyperscaler infrastructure, and where the genuine on-prem option remains open-weight models on the buyer's own hardware.

For UK and EU financial institutions specifically, the most reliable baseline remains the Bank of England and FCA's third joint survey from November 2024, which found 75% of 118 firms using AI, foundation models at 17% of use cases, and fully autonomous decision-making at 2%. No fourth wave had published by September 2026. Everything more recent about banking is vendor survey, trade press or single-firm case study.

Key Findings
The deployment split is unmeasured, and the proxies disagree by design. Menlo's survey of nearly 500 US enterprise decision-makers is the only large-N figure on open versus closed share, and it counts spend, not tokens, which structurally favours expensive proprietary models. OpenRouter's 100-trillion-token study counts tokens on a price-sensitive developer platform where coding grew from 11% to over half of traffic during 2025. Interconnects frames the divergence correctly: open models run roughly six times cheaper per call at near-parity capability, so token share and revenue share must diverge. Neither dataset isolates finance, defence or healthcare.

Open-weight adoption is bifurcating, not declining uniformly. A16z's 2025 CIO survey found Llama and Mistral adoption concentrating at the largest enterprises, driven by data-security and fine-tuning requirements rather than cost. That is consistent with the aggregate Menlo decline: mid-market firms defaulted to hosted APIs as residency guarantees arrived, while the largest regulated firms kept building. JPMorgan's LLM Suite, built in-house partly for data-control reasons and at roughly 200,000 users within eight months, is the archetype. NVIDIA's 2026 financial-services survey claims the sector is "doubling down" on open source, but it is a vendor survey with an obvious commercial interest and should be weighted accordingly.

Regulators frame the question as concentration risk, not model choice. The Bank of England's April 2025 Financial Stability in Focus note treats dependence on a handful of model and cloud providers as a systemic exposure supervisors now track. The 2024 survey found firms citing data protection and outsourcing rules, not model licensing, as the binding regulatory constraint. DORA's third-party ICT regime is the mechanism that turns this into architecture: the DACH multi-agent paper on arXiv documents tiered designs where sensitive tiers run locally precisely to keep critical functions off a single foreign provider.

Sovereignty has a measurable procurement outcome in exactly one place: France. The Ministry of the Armed Forces framework agreement with Mistral, notified in December 2025 and reported as awarded in January 2026, specifies French-controlled infrastructure and fine-tuning on defence data, steered by the AMIAD agency. The UK's Cohere arrangement is a non-binding memorandum with no disclosed value, signed with a department that no longer exists. The UK's £500m Sovereign AI Fund made its first disbursements to domestic startups, not to either sovereign-model provider, while the Commons Science, Innovation and Technology Committee warned the government lacks a coherent strategy.

Ownership sovereignty and infrastructure sovereignty have come apart. Mistral runs substantially on Azure, and the July 2026 Microsoft deal deepens that dependence even as it adds disconnected deployment options. Cohere operates no data centres. Aleph Alpha abandoned frontier-model development in 2024 and now sits inside a Canadian company, with Schwarz Group's €11bn Berlin data-centre commitment providing the German hardware. Independent writers read this as European sovereign positioning outrunning its financing; Cuddington's comparison of the UK fund against France's €109bn puts the gap at roughly a hundredfold.

The gateway layer has become the governance layer. ThoughtWorks' Technology Radar tracks LiteLLM's evolution from a multi-provider wrapper into a gateway handling retries, budgets and edge guardrails, with vLLM as the standard self-hosted inference worker. CNCF's 2025 survey puts 82% of container users running production AI on Kubernetes, with a Gateway API Inference Extension routing by model name and endpoint health. RouterArena and LLMRouterBench are the first independent benchmarks of routers, finding embedding-dependent routers such as RouteLLM carry materially higher latency than rule-based alternatives, a figure vendor documentation for OpenRouter, LiteLLM and NIM does not publish.

Classified deployment is real but runs on frontier proprietary models, not open weights. Los Alamos moved the Venado GH200 system onto a classified network in 2025 to run OpenAI's o1 and o3 against ITAR-restricted data, confirmed by NNSA and corroborated by The Register. The Pentagon's May 2026 classified-network agreements covered eight companies. DeepSeek was banned from Pentagon networks within days of release. The lesson for defence buyers is that open-weight licensing does not clear the provenance bar; a contractual relationship with a trusted vendor does, until it is withdrawn.

Healthcare on-prem deployments size models to hardware, not leaderboards. The radiology isolation-first architecture paper, the zero-egress psychiatric on-device study and the NHS-LLM build on 13B Llama weights all converge on modest parameter counts that fit a hospital's existing GPU estate. MedGemma's model card offers 4B and 27B variants for the same reason. These are among the few empirical tests of on-prem architecture in production rather than descriptions of intended design.

Evidence & Data
The regulator-measured baseline for UK finance: 75% of firms using AI in 2024, up from 58% in 2022; foundation models at 17% of use cases; 55% of use cases involving some autonomous decision-making, 2% fully autonomous; four of the top five perceived risks data-related.
Sources: Bank of England and FCA (2024) (↗); Financial Conduct Authority (2025) (↗)
Enterprise open-weight share: Menlo reports a fall from 19% to roughly 11–13% of LLM workloads between 2024 and 2025, against total enterprise generative AI spend tripling to $37bn. The July 2025 mid-year update showed the same direction.
Sources: Menlo Ventures (2025) (↗); Menlo Ventures (2025) (↗); luizneto.ai (2026) (↗)
OpenRouter platform data: open-weight models at roughly 30% of tokens through 2025 but about 4% of model-layer revenue; Chinese open-weight weekly share rising from 1.2% in late 2024 to peaks variously reported at 30%, 46% (April 2026) and 61% (February 2026) depending on outlet and window. The spread across reports of the same dataset is itself a reason to discount any single figure.

Signals & Tensions
Hosted residency guarantees are eroding the on-prem case faster than sovereignty rhetoric is rebuilding it. OpenAI's October 2025 UK data residency and Google's Sovereign Cloud tiers for Gemma 4 address the FCA's stated data-protection concern directly. The counter-signal is the June 2026 export order, which showed residency does not protect against the provider's home government. Which of these weighs more will decide the split.

Frontier-lab regulated-sector products are procurement marketing until corroborated. Claude for Financial Services, the Salesforce partnership and Meta's ANZ Bank Llama case study are vendor-reported. Mistral inside HSBC's private cloud comes from trade press, not HSBC. The one recurring independent check, METR's pre-deployment evaluations, measures capability and safety rather than deployment architecture, and cannot confirm anyone's on-prem share.

Open-weight versus open-source is being conflated where it matters most. RedMonk and Nuance Matters both flag that Llama and Mistral licences carry usage and scale restrictions that procurement lawyers must read, while press coverage treats the terms as synonyms. The auditability argument regulators care about depends on the distinction.
Sources: tecosystems (RedMonk) (2026) (↗); Substack (Nuance Matters) (2025) (↗)
Compute, not weights, may be the binding constraint on sovereignty. Hamish Low argues supply chains and GPU access decide independence regardless of model provenance. The Microsoft-Mistral and Schwarz-Berlin deals suggest European governments have quietly accepted this and are buying capacity rather than models.
Sources: Substack (Hamish Low, Cambrian Research) (2025) (↗); Linux Foundation (2025) (↗)
EU AI Act enforcement is arriving as a new variable. CNBC reported in August 2026 that Anthropic and OpenAI face scrutiny under new enforcement powers. Compliance benchmarks such as COMPL-AI and AIReg-Bench could let procurement teams test vendor claims, but no evidence yet shows a regulated buyer using them.

Open Questions
Whether the Bank of England and FCA will publish a fourth survey with a deployment-locus question. Without it, UK banking has no regulator-measured data after 2024, and the sector-specific split remains inferred.
Sources: Bank of England and FCA (2024) (↗); HM Treasury (GOV.UK) (2025) (↗)
Whether any European bank or insurer has invoked DORA's third-party provisions to move a workload off a hosted frontier API, and whether the ECB or EBA will publish the finding. The architecture papers describe designs; no supervisory action is documented.
Sources: arXiv (2026) (↗); Bank of England (2025) (↗)
What the Cohere-UK memorandum has produced beyond a headcount commitment, and whether the new cabinet AI minister will convert it into a scoped contract comparable to France's Mistral framework.
Sources: Cohere (2025) (↗); Bloomberg (2026) (↗)
What a regulated on-prem deployment actually costs to run at scale. The arXiv break-even models are parametric; no named institution has published utilisation, GPU count and total cost together.
Sources: arXiv (2025) (↗)
Whether Microsoft's disconnected Azure Local deployments of Mistral count as sovereign infrastructure under French or EU procurement rules, given the hyperscaler dependency they embed.
Sources: SiliconANGLE (2026) (↗); BankInfoSecurity (ISMG) (2025) (↗)
Whether the June 2026 export order produces measurable European migration away from US hosted APIs, or whether it fades once access is restored. Fortune documents the calls for sovereignty; no source yet documents a completed switch.
Sources: Fortune (2026) (↗)
Which open-weight families and sizes actually dominate regulated on-prem estates. Healthcare papers cluster at 4B to 27B; nothing comparable exists for banking or defence, and Red Hat's 2025 review of open models describes the supply side, not the installed base.
Sources: Red Hat Developer (2026) (↗); Google Developers (2025) (↗)
The decision a UK or EU institution faces is therefore not a choice between three measured markets but a bet on which unmeasured risk matures first: the residency and retention guarantees that hosted providers are adding, or the political access risk that one government demonstrated in June 2026 it is willing to exercise.

| v5 | Open source technology in the age of AI | McKinsey | 2025-04 | Finds organisations that see AI as a competitive advantage are over 40% more likely to use open-source models and tools than others, a McKinsey-estimated correlation (not causal) figure frequently cited to justify open-weight investment theses. |
| v6 | Sovereign AI: Building a secure AI ecosystem | McKinsey | 2025 | McKinsey's framing of sovereign AI as a procurement and infrastructure agenda rather than a marketing term, useful for distinguishing genuine sovereignty criteria from vendor positioning. |
| v7 | State of AI 2025 Report | CB Insights | 2025 | Analyst-estimated funding data showing OpenAI, Anthropic and xAI raised a combined 86.3 billion dollars in 2025 (38% of total AI funding), context for how concentrated hosted-frontier-model capital is relative to sovereign and open-weight challengers. |
| v8 | State of AI Q3'25 Report | CB Insights | 2025-10 | Records Mistral AI's 1.5 billion dollar Series C among the largest Q3 2025 model-layer deals, evidence that sovereign-positioned European labs are attracting frontier-scale capital alongside US incumbents, not merely government goodwill. |
| v9 | Executive Survey: AI Moves from Pilots to Production | Bain & Company | 2025 | Bain's executive survey finding rising data-security and privacy concerns specifically among companies that have moved gen AI from pilot to production, a leading indicator for why regulated firms slow down at the scaling stage rather than the pilot stage. |
