DeepSeek vs ChatGPT, for this page, is a data question. The general quality comparison stays at DeepSeek vs ChatGPT: which is better and on the side-by-side page. Use those when you are comparing answers on public topics. Use this page when the prompt may contain customer, employee, source code, or unreleased business information.
Key takeaway: Keep company files out of any consumer chat until security has read the current terms for that plan. A ChatGPT Team or Enterprise conversation is about admin controls, and those prices are on OpenAI's page. A DeepSeek account is not a private vault just because the model is capable.
Research reviewed: October 30, 2026. This is desk research by the AI Savr editorial team. We did not run a private lab test, and we did not invent scores, traffic numbers, or hands-on results. Confirm live prices on the vendor page before you buy.
Which seat may see company data?
Neither seat may see company data by default. Security reads where the prompt is processed, whether it is used for training, and how long it is kept, on the exact plan you would buy. Public notes can go to a consumer chat if policy says so. Customer records, payroll, health files, and unreleased financials wait for a written yes. ChatGPT Team and Enterprise are the OpenAI plans to read for admin controls. Their prices are on OpenAI's pricing page. DeepSeek's current access terms are on DeepSeek's site.
| Data | Seat to discuss | Blocked until review |
|---|---|---|
| Public notes | ChatGPT or DeepSeek | Customer records |
| Files already in Microsoft 365 | Microsoft Copilot | A personal chat login |
| A long brief from approved notes | Claude | Unreleased financials |
| A company ChatGPT workspace | Team or Enterprise | A free personal account |
How to separate public drafting from company data
DeepSeek only after security reads the terms
DeepSeek is a model family people look at for capable answers at a lower cost. That interest does not decide where a company prompt may go. Read DeepSeek's current terms for the access you would use, including where processing happens and whether inputs train models.
Choose it when: security has finished that reading and the data in the prompt is allowed.
Leave it when: you are about to paste a customer file into a personal account to save money.
Price and access: Read DeepSeek's site for current access. This guide does not quote a price. Confirm before you buy.
A real use: Give DeepSeek a public product question and keep the sources you open. Leave the CRM export on the company drive until security names an allowed plan.
ChatGPT on a plan with an admin
ChatGPT is the seat to discuss when the company wants a known vendor, an admin, and a plan page it can file. Plus and Pro are individual plans. Team and Enterprise are the plans to read when several people and a data review are involved. The individual checkpoints do not answer the company-data question.
Choose it when: you need admin controls and OpenAI's business terms match the review.
Leave it when: staff are using personal free accounts for customer text.
Price and access: Public checkpoints in late October 2026: Go about $8, Plus $20, and Pro from about $100. Team and Enterprise prices must be read on OpenAI's pricing page. Confirm before you buy.
A real use: Ask for a rewrite of an approved public FAQ. Store the customer spreadsheet outside the chat until the Team or Enterprise terms are accepted in writing.
Claude under the same review
Claude belongs in the same security queue as any other external model. It is useful for long edits of notes that are already cleared. A $20 Pro seat is an individual plan, and it is not an automatic company data agreement.
Choose it when: the notes are cleared and the remaining work is a long brief.
Leave it when: you have not read Anthropic's terms for the plan you would buy.
Price and access: Claude Pro is $20 monthly. Company terms and any team plan must be read on Anthropic's pricing page. Confirm before you buy.
A real use: Paste a cleared outline and ask for a memo that adds no new facts. If the outline is still confidential, wait for the written approval.
Microsoft Copilot when the file is already in the tenant
Microsoft Copilot is the option to review when the file already lives in Microsoft 365 and the company would rather keep the prompt in that tenant. It is not a reason to paste the same file into DeepSeek or a personal ChatGPT account. Business pricing still has to be read on Microsoft's site.
Choose it when: the data is already in a Microsoft tenant and IT can name the license.
Leave it when: the company does not use Microsoft 365.
Price and access: Microsoft 365 Premium, which replaced Copilot Pro for individuals, was about $19.99 in late October 2026 trackers. Business Copilot pricing must be confirmed on Microsoft's site. Confirm before you buy.
A real use: Run the question inside the tenant on a file security has classed as allowed. Do not export that file to a personal chatbot to compare answers.
A data check before any paste
Classify the text before you pick a model. The model choice is the second step.
- Label the text. Public, internal, customer, employee, or unreleased. If you cannot label it, do not paste it.
- Read the plan, not the homepage slogan. Find training use, retention, and region for the exact plan on the vendor page.
- Block personal accounts for company files. A free login someone opened at home is not the company workspace.
- Use cleared notes for drafts. DeepSeek, ChatGPT, or Claude may shape text security has already allowed.
- Write the exception list. Name who may approve a new data type. Confirm before you buy any new seat.
Limits this comparison does not settle
This page does not certify either vendor, and it does not claim that one of them trains on your prompts. Those facts live in the current terms. Open weights, a low price, or a familiar brand do not replace that reading. The quality comparison on the older AI Savr article is a separate decision, and it still does not authorize a paste.
What security and the team lead should publish
Publish a one-page rule: public drafting may use the approved chat, and customer or employee data may not, until a named plan is accepted. Point people who want a quality bake-off to the existing DeepSeek comparison. Point people who hold Microsoft files to the tenant assistant. Review the rule when a vendor changes its terms.
Questions worth asking before you buy
Ask where prompts are processed, whether they train models by default, how long they are kept, whether an admin can delete a user, and which agreement covers the plan on the invoice. If the vendor cannot answer for the plan you will buy, do not put company data there.
For companies that need more than a subscription
Companies that outgrow these seats, because company data has to be queried inside an internal system under an approval rule, can talk to AI Savr about a custom agent at the contact form. This guide does not quote a services price.
If an off-the-shelf tool cannot meet your data, approval, or security rules, talk to AI Savr about a custom AI agent. Use the directory to compare live tools first, and vendors can submit a product.
Frequently asked questions
Can staff paste customer data into DeepSeek?
Only after security reads the current terms and writes an approval for that data type. A personal account is not that approval.
Does ChatGPT Team automatically make every paste safe?
Team is the plan to read for admin controls. Safety still depends on the terms you accept and on the data rule you publish. The price is on OpenAI's page.
Where is the general DeepSeek versus ChatGPT comparison?
The older AI Savr article and the side-by-side comparison cover the general choice. This page is about company data.
Are individual Plus or Pro seats enough for company files?
Plus was about $20 and Pro from about $100 in late October 2026 checkpoints. Those are individual plans. Company files need the admin plan security accepts. Confirm before you buy.
What about files that already sit in Microsoft 365?
Review Microsoft Copilot inside the tenant. Business pricing must be confirmed on Microsoft's site.
Does a lower price change the data rule?
The data rule stays the same. A cheaper chat still needs a written answer on training, retention, and location.
