Microsoft Copilot vs DeepSeek: pricing and free tier side by side

Microsoft Copilot vs DeepSeek

Amo and Pimi: Which one to choose between these two

Amo

Pimi, look at this price gap — to use Copilot's advanced features you have to subscribe to Microsoft 365 Premium at US$19.99/month, while DeepSeek's web version is just plain free. That's way too big a gap, isn't it!

Pimi

Don't rush to call it excessive — the two do different things. What Copilot sells is deep Office integration; being able to summon it inside Word, Excel, and Outlook is the point, not pure chat.

Amo

Okay, okay, but that depends on whether you actually have that workflow. DeepSeek doesn't have this kind of office integration — it's pure chat + API. Without an Office workflow, US$19.99/month is meaningless to you.

Pimi

Let me add something you just left out: if you already have Microsoft 365 Personal (US$9.99/month) or Family (US$12.99/month), basic Copilot features are now built in — you don't need to pay an extra US$19.99.

Amo

Let's calculate it a different way then — if you hook DeepSeek up to your own system as an API, V4-Flash input is only US$0.0028 per million tokens (cache hit), which isn't even the same unit of comparison as Copilot's bundled subscription.

Pimi

Alright, let me spell out what you're actually buying on each side: Copilot Premium at US$19.99/month buys you 'Office integration + advanced agents,' while DeepSeek buys you 'cheap model compute' — one's an office tool, the other's a developer tool.

Amo

So let's wrap it up like this: if you just want to chat and ask free questions, DeepSeek's web version is enough; if your work is inseparable from Office and you want AI help writing reports and decks, Copilot's US$19.99/month integration value is where it pays off.

So the conclusion is

The web version of Microsoft Copilot offers basic text conversation for free, but advanced features such as Copilot Chat, Researcher/Analyst agents, and AI image generation in Office require a subscription to Microsoft 365 Premium at US$19.99/month (US$199.99/year, confirmed on microsoft.com/en-us/store/b/copilotpro official website). Additionally, M365 Personal (US$9.99/month) and Family (US$12.99/month) subscriptions now include basic Copilot functionality. DeepSeek's web chat is completely free (with peak traffic limits), but the true cost lies in its API: V4-Flash charges US$0.0028 per million tokens for input (cache hit) and US$0.28 for output (confirmed on api-docs.deepseek.com official website). The two services have different natures, with Copilot's value lying in its integration with the Office ecosystem and DeepSeek's value in its low-cost model computing power, making them non-direct substitutes.
