Glean vs Gemini Enterprise: cost per seat, the published quota each license actually buys, and the number each vendor leaves off its own pricing page.

The seat rate is the wrong number to compare, and here is the arithmetic that shows it

Almost every comparison of these two products lines up a seat price against a seat price and stops. That cannot work here, because only one of the two vendors publishes a seat price, and because the quota attached to each seat is designed on a completely different principle. The useful comparison is how many queries a seat entitles you to before anything else starts billing, and both vendors do publish enough to work that out.

Take Gemini Enterprise Standard. Google publishes 160 assistant queries per license per day. Over a seven day week that is 1,120 queries of entitlement per seat, and critically it covers every kind of query: a one line lookup and a long reasoning request both take one off the same counter. Now take Glean Enterprise Flex. Fast Mode queries are unlimited, so simple lookups never touch a meter at all, and reasoning-mode queries on standard models are included up to 100 per user per week before FlexCredits begin to draw.

The full edition ladder, the seat caps and the trial terms sit on our Gemini Enterprise pricing page, and we work through whether moving up a tier actually pays in Gemini Enterprise Plus license cost.

Those two numbers, 1,120 and 100, look like a rout until you notice they are measuring different things. Google's 1,120 has to absorb all of your organization's lookups, and in a real deployment lookups are the overwhelming majority of traffic. Glean's 100 only has to absorb the reasoning requests, because the lookups are free. So the honest rule is this: if your people mostly search, Glean's unlimited Fast Mode means the meter is very hard to hit and Google's 160 a day is the constraint you will actually run into. If your people mostly reason, Google gives roughly eleven times more headroom per seat before anything meters, and Glean starts drawing credits at query 101. Neither is cheaper in general. Which is cheaper depends on a ratio inside your own company that neither vendor asks you about.

What the pooling rule does to a plan built per head

The second thing that breaks a naive comparison is that Gemini Enterprise quota is not personal. Google states that feature quotas are pooled across users on the same edition within a project and location, and then gives the example that makes the risk concrete: with ten Standard licenses, "one power user can use 500 queries, leaving 1,100 queries for the remaining users", and "individual usage isn't capped at the per-user limit" unless an administrator configures one.

For most buyers that is fine and even generous, because average usage is lumpy and pooling smooths it. The failure mode is specific: a small number of heavy users, an agent left on a schedule, or a pilot team that gets enthusiastic can consume a shared day before the rest of the company logs in. The mitigation is also specific, which is to configure per-user caps rather than assume them, and that is an administrative task somebody has to own.

Storage pools on a different axis again, and this one is easy to misread in the other direction. Google states storage and data indexing is pooled across all users in a project and location regardless of edition, and gives the worked example: 100 Standard licenses at 30 GiB plus 50 Plus licenses at 75 GiB produces one combined pool of 6,750 GiB shared by everybody. The query pools for those same two groups do not combine. So in a mixed-edition tenant you get one shared disk and two separate meters, which is not what anyone would guess from the pricing card.

What you can and cannot learn about Glean before a sales call

Glean's pricing page is a demo request, and we want to be fair about that rather than score a point off it: plenty of serious enterprise software is sold this way and it does not mean the product is overpriced. It does mean you cannot budget for Glean from public information, and you should plan your evaluation timeline accordingly.

What you can learn without a call is more than most buyers realise, because Glean's documentation is genuinely detailed. It publishes two current pricing models and refers to a third. Glean Core Suite is seat-based, with a long list of what is included in the seat fee and what instead draws on "Model Hub Usage", billed at the model provider's API rates from a published table. Glean Enterprise Flex is the newer one, a per-user license plus a pooled allowance of FlexCredits, with the entitlements we set out above. And the FlexCredits dashboard documentation mentions a "legacy Glean Enterprise plan" whose usage dashboard has been withdrawn. Three pricing regimes exist concurrently, so the first question on a Glean call is which one you are being quoted.

The detail worth taking into that call is the list of what consumes FlexCredits from the very first use: premium-model queries, Code Writer, slide generation, Deep Research, meeting notes, and every agent run, including agent runs triggered from an ordinary assistant question. There is also a rule that a thinking query consuming more than 30 FlexCredits is counted as multiple queries, and a note that follow-up questions count as separate queries. Ask for the FlexCredit rate and the included pool size in writing, because those two numbers are the entire bill and neither appears anywhere public. We keep what is publicly knowable about the vendor on our Glean pricing page.

Where neither of these is the right purchase

We sell a flat-rate AI agent, so treat this section as interested but check it anyway. Glean and Gemini Enterprise are both platforms for a company that already has a lot of internal content and a team who will connect it, tune it and build agents on it. They answer questions about your documents extremely well. They do not, on their own, call your prospects back, keep your CRM honest, chase an unsigned document or produce the same report every Monday without someone having built and maintained that workflow first.

That is a real distinction and it cuts both ways. If your problem is that nobody can find anything across six systems, buy one of these two and do not let us talk you out of it. Gemini Enterprise Business at $21 a seat with a 30 day self-serve trial is the cheapest honest way to find out whether that class of product helps you at all, and you can run that test this week without a sales call. If your problem is that a list of recurring jobs does not get done because the person who would do them is busy, a search platform will not fix it no matter which of the two you pick, and a flat $149 a month agent that owns the jobs is a different purchase entirely.
