What the bank is actually buying
The feature list points at the model; the value capture does not. ChatGPT for Financial Services reads figures, tables and notes across documents and periods and outputs into admin-published Excel, Word and PowerPoint templates in the firm's house style, with figure-level citations. That template library and style guide is the switching cost. Every hour a bank spends configuring output format is lock-in that has nothing to do with any benchmark score, and access is sales-gated to eligible institutions only — which buys OpenAI average contract value and compliance control at the cost of velocity. Mid-market finance teams, the buy side and corporate development are structurally unserved by that choice for the next 12 to 24 months.
The same pattern one layer down
Per TLDR Data, OpenAI's Data agent connects to approved company data and business definitions, respects existing permissions, integrates with major data and business-intelligence platforms, and can recommend or carry out approved follow-up actions. Turing Post adds the detail that decides where value sits: the agent only functions using the organization's own definitions of metrics and business terms. The interface commoditizes; the semantic layer — who owns the canonical definition of revenue, churn or exposure — becomes a chokepoint asset and an acquisition target.
Three reports converge on the harness itself being platform territory. OpenAI shipped a managed Agents API in public beta that hosts the harness and runs agents in its own sandboxes, customer infrastructure, or third-party providers. Salesforce named the category outright, launching an Enterprise AI Harness with an AI Control Plane positioned as model-agnostic. Boomi shipped the same capability set as routine release notes, with native tracking of Claude managed agents' tools, models and token consumption — and disclosed its own window: Orchestrate is generally available in the US only, and Knowledge Hub is early access.
| Layer | Who holds it now | Durability |
|---|
| Distribution surface | Microsoft in Office, OpenAI in ChatGPT Work | High — owns the file and the default |
| Frontier model access | Three vendors, one dropdown | Eroding — interchangeability now demonstrated |
| Licensed data feeds | Daloopa, PitchBook, LSEG, Crunchbase | Low — direct user relationship severed |
| Firm-specific configuration | OpenAI, in the finance vertical | High and compounding |
| Orchestration and verification | Effectively nobody | Unproven, demand validated |
The layer with validated demand and no supply
The reference implementation for governed multi-model work is a community plugin. Astrable splits planner, builder and verifier across vendors — Astra scopes, Fable 5.1 builds via Claude Code, Astra verifies — and emits an explicit verification receipt, because a tool result proves that a tool ran, not that the work is correct. It requires Node 24 and two paid subscriptions. That is the exact failure mode that stops a bank letting an agent touch a valuation model, and the buyer is a model-risk-governance function with a budget line rather than discretionary spend.
TLDR IT names the adjacent hole: with agent gateways at enterprise scale the hard problem is authorization rather than integration, the primitives have converged on identity, per-tool scopes, consent and audit logs, and the incumbent claiming that layer is doing so through commentary rather than a referenceable product.
In vertical AI, the durable asset is the customer's own artifacts — templates, style guides, metric definitions — not the model that reads them.
