Making your firm AI-native with ChatGPT
The baseline to set before any agent: which plan clears a regulated bar, where the UK region stops, and what a product line that has changed shape four times in twelve months means for anything you build on it.
For a regulated firm, ChatGPT Enterprise rather than Business is the configuration that clears the bar, because Business has no SCIM, caps at 200 seats and is not named in OpenAI's residency list. The UK region on Enterprise covers storage only, with processing elsewhere. Programmatic work is better run on Microsoft Foundry in your own Azure tenant.
Report Overview
ChatGPT is the product your people already know, and at rollout that is worth more than most feature comparisons admit. This is what a regulated firm actually buys, where the UK region stops, and what to build on given a product line that has changed shape four times in twelve months.
Everything here was checked against OpenAI and Microsoft documentation between 1 and 3 September 2026.
Key facts
- $20
- Per seat per month for ChatGPT Business on an annual plan. It caps at 200 seats and has no SCIM, which is why a regulated firm usually needs Enterprise. List price as verified 1 to 3 September 2026.
- UK
- Region available on Enterprise, for storage only. Processing happens elsewhere, so the residency position is something you write down rather than assume. As verified 1 to 3 September 2026.
- 30 Nov 2026
- When Agent Builder and the Evals platform shut, which is why anything you build belongs on the Agents SDK, the Responses API and MCP.
- 30 days
- How long compliance logs are retained, so a regulated firm exports them to its own SIEM rather than relying on the platform to hold them.
Every price and regulatory date on this page is as verified between 1 and 3 September 2026.
01 · WHAT IT MEANS
What does AI-native mean on ChatGPT?
Four things true at once. Everyone has a governed assistant inside the tools they already use. The firm's procedures exist as something a new joiner runs on day one. Your systems of record are reachable through one connector you own. And the heaviest process runs itself, with a named person signing and an evidence trail a regulator can read.
02 · THE ANSWER
What does a regulated firm actually buy on ChatGPT?
Two purchases, and you probably need both. Business at $20 a seat fails a regulated bar: no SCIM, a 200-seat cap, and no place in OpenAI's data residency list. Enterprise is the control surface. Then a separate API organisation, although for a Microsoft-resident firm we run programmatic work on Foundry in your own Azure tenant instead. As verified between 1 and 3 September 2026.
03 · THE WORK
What does the work look like on ChatGPT?
Eleven worked examples on one complexity scale, built on Projects, Workspace Agents, Company Knowledge and ChatGPT Work. Tier 1 a champion does unaided. By Tier 3 the work belongs on the Agents SDK and the Responses API, hosted in your own Azure tenant, because those are the primitives that will still exist in five years.
04 · THE HONEST PART
Where is ChatGPT the wrong tool?
Record mode is macOS only, so in-person capture on a Windows firm goes to Teams instead. The synced connector excludes Purview-labelled files and does not index SharePoint pages. MCP developer mode is web only. And Agent Builder shuts on 30 November 2026, which is the reason to build only on the open primitives.

Frequently asked questions
Is ChatGPT Business enough for a regulated firm?
Usually not. Business has no SCIM, no synced groups and no directory provisioning, so joiners and leavers are a manual list somebody has to keep. It caps at 200 paid seats. Any member can invite another member while seats are available, and OpenAI states plainly that this cannot be restricted. It has no SharePoint synced connector, because the admin-managed sync behind Company Knowledge is Enterprise and Edu only. And it is not named in OpenAI's data residency list. Enterprise is the configuration that clears the bar. As verified between 1 and 3 September 2026.
Does ChatGPT store our data in the UK?
On Enterprise there is a UK region and it covers storage only. Processing happens elsewhere. That is a lawful position for a UK or Irish firm on the usual transfer route, recorded in a DPIA and a transfer risk assessment, but it is not the same as in-country processing and a board paper should not imply that it is. Business is not named in the residency list at all. Position as verified between 1 and 3 September 2026.
What happened to Agent Builder, and what should we build on instead?
Agent Builder and the Evals platform both launched in October 2025 and both shut on 30 November 2026. That is not a reason to avoid OpenAI. It is a reason to build only on the Agents SDK, the Responses API and MCP, which are open and portable, and to host in your own Azure tenant on Foundry Agent Service. A proposal that does not name those primitives is a 2025 proposal.
How does ChatGPT connect to our Microsoft 365 tenant?
Through the synced connector behind Company Knowledge on Enterprise and Edu. Two limits shape the design. The connector excludes files restricted by Purview sensitivity labels and does not index SharePoint site pages, and it caps files at 100 MB. Company Knowledge also has to be switched on per conversation. Write actions into Microsoft 365 are admin-gated and shallow. If the excluded content is the content that matters, Copilot's native Graph grounding will reach what ChatGPT cannot.
Where is ChatGPT the wrong tool?
Five cases. In-person meeting capture on a Windows firm, because Record mode is macOS only with a four-hour cap. A policy estate that is heavily labelled or lives on SharePoint pages, because the synced connector excludes both. Anything approved from a phone, because MCP developer mode is web only. A live event stream, because no seat product on any platform processes events at that latency. And anything that needs a visual builder to survive a five-year audit, given the 30 November 2026 shutdown.
Which model should our people be using?
In ChatGPT your staff see effort settings rather than model names, so the choice that matters commercially is the one your build makes per call. GPT-6 Astra is the depth model, at $10 per million input tokens and $50 per million output on the API, and it is off by default on Enterprise at launch. GPT-5.6 Terra remains the workhorse for judgement work at normal volume and Luna the high-volume, latency-sensitive tier. Astra is days old at the time of writing, so treat the published benchmarks as a reason to test rather than a reason to promise. Prices as verified between 1 and 3 September 2026.
Is the deck really free?
Yes. A name and a work email, and the 21 slides open in a new tab. No paywall and no obligatory follow-up. The 43-page ChatGPT playbook behind it is not a download. We bring it to the conversation if we have one.
