Organization-wide. UK justice department. One-year update of its AI Action Plan, September 24, 2026.
GOV.UK (Ministry of Justice), published Sep 24, 2026Read the report (opens GOV.UK (Ministry of Justice) in a new tab)
Observation
The UK Ministry of Justice runs targeted rollouts of ChatGPT Enterprise and Copilot side by side.
Takeaway
A department on Microsoft 365 can still roll out ChatGPT Enterprise beside Copilot, so plan the data rules for both before either rollout widens.
What happened
The Ministry of Justice's one-year update on its AI Action Plan, published September 24, 2026, describes targeted, ongoing rollouts of both ChatGPT Enterprise and Copilot for Microsoft 365 to staff. It gives no licence counts or measured results.
“…targeted, ongoing rollouts of Copilot for Microsoft 365 and ChatGPT Enterprise…”

Observation
Brex buys a few seats of ChatGPT, Claude and Gemini and lets each employee pick one.
Takeaway
Buy a few seats of each and let use decide; Brex keeps employees free to switch.
What happened
Brex chose not to standardize on one assistant and runs several beside each other: it procures a small number of seats of several and lets employees request a ChatGPT, Claude or Gemini licence through ConductorOne in Slack. Reggio describes this on Latent Space as keeping the company able to switch while the products keep changing.
“What we do instead of like trying to pick a single solution is we will procure like a small number of seats, like multiple solutions, and then we’ll give employees the ability to pick whatever one they want to use.”

Rippling's product chief uses ChatGPT beside Gemini to phrase ideas, never to originate them.
Takeaway
Hand ChatGPT a finished argument to sharpen; MacInnis keeps the thinking himself.
What happened
MacInnis writes the idea himself and uses ChatGPT and Gemini to find crisper ways to say it. He finds both good at refining the wording and not useful for coming up with the ideas.
“I do turn to AI, ChatGPT and Gemini, where I take a really, let's say, angular view of some topic and I give ... really, I write the essay for the AI and I'm like, "Look, this is the crisp idea I want to communicate. Help me come up with pithy ways to articulate these things."…”

Takeaway
Expect heavy users to split work across assistants by task, and budget a second seat for them.
What happened
Wilkinson reports that his basic stack is Claude, ChatGPT and Gemini: Claude for writing, which he rates best, Gemini for very large inputs, and ChatGPT for everything else. He describes his own use, with no company-wide purchase.
“Other tools, I mean otherwise, it's the basic stack of Claude and ChatGPT and Gemini. And Gemini I use mostly for things that are really large.”

Takeaway
Memory keeps people in ChatGPT; test new workflows in both before you build on one.
What happened
Shipper reports that o3 in ChatGPT is the first thing he opens and that memory is what still sets it apart from Claude. Every uses ChatGPT and Claude as general-purpose tools to try a workflow before building a product around it.
“I do love Claude. I would say I'm generally... My first thing that I open is o3. I'm a ChatGPT boy.”

Observation
A product manager uses projects in both ChatGPT and Claude after ChatGPT's memory mixed his contexts, and prepared for a role Meta approached him about in a Claude project.
Takeaway
Keep separate work in separate projects, and check whether memory crosses them before relying on it.
What happened
Arnovitz uses both ChatGPT Projects and Claude Projects as folders of chats with their own instructions and knowledge. He reports that ChatGPT's memory mixed unrelated parts of his life, such as running and product reviews, and that projects keep each context apart. When Meta approached him about a role, he opened a project in Claude and built a coach from frameworks he collected.
“And what happened was the memory feature was mixing stuff up.”

Its own announcement, published Mar 21, 2025Read the report (opens the announcement in a new tab)
Observation
In Pennsylvania, a year-long pilot across state agencies came before any wider purchase.
Takeaway
Run a bounded pilot that collects participant feedback, and plan training time and human review before buying for a whole workforce.
What happened
Pennsylvania gave 175 employees across 14 agencies ChatGPT Enterprise for a year. Participants reported saving an average of 95 minutes a day on writing, research, summarization, and IT support. More than 85% reported a positive experience, although 48% had never used ChatGPT before. The state concluded that the tool needs employees' expertise and judgment, and stressed human oversight.
“The findings revealed that employees had a highly positive experience, reporting an average time savings of 95 minutes per day while using ChatGPT for writing, research, summarization, and IT support…”

Ethan Mollick gave ChatGPT Work and Claude Cowork the same seminar task, and ChatGPT sent an email he had not reviewed.
Takeaway
Decide what each agent may send or change on its own before a trial, and test both on the same task with the same settings.
What happened
Mollick asked both agents to connect to his Gmail, prepare an MBA seminar with slides and answer outstanding messages. Both built teaching material. Claude drafted a reply; ChatGPT sent one to his colleagues, because he had earlier let ChatGPT send email on his behalf and told Claude to ask first.
“To use the computers provided by the AI companies, the mode you want is called ChatGPT Work in ChatGPT, and Cowork in Claude (the naming will not get less confusing, I am sorry to say).”

Observation
At California State University, governance came first and communication proved the hardest part of a 22-campus rollout.
Takeaway
Settle governance before choosing the tool, and budget for continuous communication. Verification stays part of the work.
What happened
After a systemwide committee recommended one enterprise AI tool, CSU rolled out ChatGPT Edu in March 2025. By fall 2025, it had provisioned about 225,000 accounts across all 22 campuses. More than 4,000 people completed system-level training. A survey drew 94,060 responses from students, faculty, and staff. Of faculty respondents, 97% said AI output must be verified. Kennedy says communication across campuses was the hardest part.
“Roughly 225,000 accounts have been created in the CSU ChatGPT Edu instance.”

At BBVA, a year of ChatGPT Enterprise with training and a shared GPT library led the bank to more than triple its licenses.
Takeaway
Pair licenses with training and a shared library of assistants, and measure daily use before buying more seats.
What happened
BBVA issued 3,300 ChatGPT Enterprise licenses in May 2024. It trained employees on data security and confidentiality. A practice community and an internal library of about 1,000 GPTs supported use across the group. A year later, BBVA expanded to 11,000 licenses. It reports that 83% of licensed users use ChatGPT at least once a day. Employees who automate tasks report saving 2.8 hours a week.
“According to data from the bank’s Global AI Adoption department, employees using ChatGPT to automate tasks report saving an average of 2.8 hours per week…”

LinkedIn builds internal knowledge agents on ChatGPT Enterprise and Copilot, and credits its own customization for the gains.
Takeaway
Budget for the internal customization work; LinkedIn says that, more than the seat, drove its gains.
What happened
Cohen reports that LinkedIn's knowledge-corpus agents run on everything from Copilot Enterprise to ChatGPT Enterprise, and that LinkedIn's own customization and orchestration produced the biggest gains. LinkedIn is owned by Microsoft, OpenAI's largest investor.
“And I would say for a lot of those kind of knowledge corpus agents, we're using everything from Copilot Enterprise to ChatGPT Enterprise. By far though, the most important part was basically our own customization of it. That's been where we saw the biggest gains.”
