Gemini Enterprise Agent Platform pricing in 2026: the July-September billing dates that raise your bill

Summary. Between July 1 and September 1, 2026, four agent-infrastructure services on Google Cloud's Gemini Enterprise Agent Platform stop being free and start metering. Skills Registry billing begins July 1, 2026; Agent Gateway (Agent-to-Anywhere) becomes effective July 13; Semantic Governance Policies start August 1; and both Memory Bank and Sessions begin September 1. Each meters on Agent Compute at $0.085 per vCPU-hour, with storage at $0.30 per GiB-month. On top of that sit model tokens (Gemini 3.1 Pro at $2/$12 per million input/output tokens) and seat editions from $21 to $60 per user per month. If you piloted agents while these components were free, your production bill in the second half of 2026 will not match your pilot. This breakdown maps every line item, with the dates, so platform and FinOps teams can budget before the invoices change.

Google Cloud CEO Thomas Kurian describes the product as "the new front door for AI in the workplace." The pricing behind that front door has three separate layers that teams routinely confuse: a per-seat subscription, per-million-token model charges, and per-hour agent-infrastructure metering. Getting the layers wrong is how a pilot that cost a few hundred dollars becomes a five-figure monthly production line item. This is the Gemini Enterprise Agent Platform launch priced out in full.

The three layers you actually pay for

Gemini Enterprise (capital E, the standalone platform formerly called Agentspace) launched in October 2025 and is a Google Cloud product, not a Google Workspace add-on. That distinction matters because the two are billed separately and buyers frequently merge them in a budget line.

The Agent Platform bills across three independent layers:

• Seat subscriptions, charged per user per month, for access to the platform, enterprise search, and the no-code agent builder.
• Model tokens, charged per million input and output tokens, for every call an agent makes to a Gemini model.
• Agent infrastructure, charged per vCPU-hour and per GiB-month, for the memory, sessions, skills, and gateway services that keep an agent running between prompts.

A seat fee does not cover token or infrastructure consumption. Compute stacks on top of the subscription, and for a busy agent the consumption layer usually dwarfs the seat fee. That is the single most common budgeting error we see when teams move an agent from pilot to production.

The 2026 billing calendar: what starts metering, and when

The change that reshapes second-half budgets is not a rate rise. It is that several services which ran free during preview begin billing on fixed 2026 dates. Google's own Agent Platform pricing page lists each one.

Component	What it meters	Rate	Billing starts
Skill Registry	Storage plus read/write operations	$0.30/GiB-month storage; $0.085/vCPU-h per 1M writes	July 1, 2026
Non-global endpoints	Regional model serving premium	About 10% over global token rates	July 1, 2026
Agent Gateway (Agent-to-Anywhere)	Agent Compute for API and authorization calls	$0.085/vCPU-h, roughly 15,000 calls	July 13, 2026
Semantic Governance Policies	Policy evaluation on agent actions	Agent Compute (vCPU-hours)	August 1, 2026
Memory Bank	Memory storage and operations	$0.30/GiB-month; $0.085/vCPU-h per 1M writes	September 1, 2026
Sessions	Conversation history and state	$0.30/GiB-month; $0.085/vCPU-h per 1M writes	September 1, 2026

Read operations are cheaper than writes: one Agent Compute vCPU-hour ($0.085) covers about 3 million read API requests, while the same $0.085 covers 1 million write operations. A free usage tier applies per month, per account, for each resource, so small agents may still land near zero. Production agents that hold long conversations, write memory frequently, or call many external tools will not.

Model token rates on the platform

Every agent turn spends model tokens. The platform prices each Gemini family separately, and the gap between tiers is wide enough that model choice, not agent design, often decides the bill. These are the published per-million-token rates as of July 2026.

Model	Input ($/1M)	Output ($/1M)	Cached input ($/1M)
Gemini 3.1 Pro	$2.00	$12.00	$0.20
Gemini 3.5 Flash	$1.50	$9.00	$0.15
Gemini 3 Flash	$0.50	$3.00	$0.05
Gemini 3.1 Flash-Lite	$0.125	$0.75	N/A
Gemini Deep Research Agent	$2.00	$12.00	$0.20
Gemini Omni Flash	$1.50	$9.00	N/A

Output tokens cost six to eight times more than input across the Pro and Flash tiers, so a chatty agent that returns long responses is expensive in a way that a retrieval agent returning short answers is not. Cached input is an order of magnitude cheaper than fresh input, which rewards agents that reuse a stable system prompt and context. Two more rules affect the total: if a single request's input context runs longer than 200,000 tokens, all tokens in that request are charged at long-context rates, and a tuned model endpoint costs 1.5 times the base model. For a deeper tier-by-tier view, see our budget LLM tier cost comparison and the note on Gemini 3.6 Flash token efficiency.

Image generation is priced on the same page. Nano Banana Pro (Gemini 3 Pro Image) charges $1 per million input tokens, $6 per million text output tokens, and $60 per million image output tokens, where a 1K or 2K image costs about $0.134 and a 4K image about $0.24. Nano Banana 2 (Gemini 3.1 Flash Image) is cheaper at $0.25 input, $1.50 output, and $30 per million image output tokens.

Grounding and tool calls: the charges agents trigger silently

An agent that searches the web or queries your data spends money outside the token meter. Grounding with Google Search and Web Grounding for Enterprise include 5,000 queries per month at no charge, aggregated across all Gemini 3 models, then bill $14 per 1,000 search queries. That billing started January 5, 2026. One user request can fan out into several search queries, and you are charged for each query performed, not per user request. Grounding with Google Maps follows the same structure. Grounding with your own data is separate at $2.50 per 1,000 prompts.

These tool charges are easy to miss because they do not appear in a token estimate. An agent that grounds every answer against Google Search can quietly pass the 5,000 free queries in a day at moderate traffic, after which each additional thousand queries adds $14. FinOps teams that model only tokens under-forecast the bill. The same discipline that governs agentic FinOps on Azure applies here: meter the tool calls, not just the model.

Seat editions: the subscription layer

The subscription layer has four editions. Google positions them by capability and support rather than by raw usage, and independent pricing trackers report the list rates below. Annual commitment is roughly 17% cheaper than the flexible monthly option, and volume discounts of 10% to 20% are reported above 500 seats.

Edition	Annual ($/user/mo)	Flex ($/user/mo)	Notes
Business	$21	$21	Entry tier for smaller teams
Standard	$30	$35	Higher quotas and controls
Plus	$50	$60	Advanced governance and support
Frontline	Custom	Custom	150-seat minimum, deskless workers

As reported by pricing trackers Coworker AI and GoSearch, the actual cost an organisation pays is rarely the list price, because compute consumption stacks on top and the commit-versus-flex choice swings the per-seat figure by about 17% to 20%. Treat the seat fee as the floor, not the estimate.

A worked budget: pilot versus production

Consider a 25-seat customer-service agent on the Standard edition. The seat layer is fixed: 25 users at $30 annual is $750 per month. If the pilot ran before July 2026, that was close to the whole bill, because Skills Registry, Sessions, and Memory Bank were free.

From September 2026, the same agent in production pays for the infrastructure it uses. Sessions stores every conversation and bills storage at $0.30 per GiB-month plus write operations at $0.085 per million. Memory Bank adds the same structure for retained user memory. If the agent grounds answers against Google Search and clears the 5,000 free queries, it adds $14 per additional thousand. Model tokens depend on the tier: on Gemini 3 Flash at $0.50/$3, a light agent stays inexpensive; on Gemini 3.1 Pro at $2/$12, the same traffic costs four to eight times more per turn. The seat fee did not move. Everything metered on top of it did. That gap between a pre-July pilot and a post-September production run is the number to put in front of finance now.

India-specific considerations

Indian teams face one extra line. From July 1, 2026, non-global endpoint pricing takes effect for the generally available Gemini 3 and later families, and before that date global pricing applied to non-global endpoints. Regional endpoints such as Mumbai (asia-south1) carry roughly a 10% premium over the global rate, so Gemini 3.1 Pro input moves from $0.125 to about $0.1375 per relevant unit on a non-global endpoint.

For regulated entities, that premium is often not optional. The Digital Personal Data Protection Act 2023 (DPDP) and sector rules push banks, insurers, and healthcare providers toward keeping personal data in-country, which means routing agents through regional endpoints and paying the non-global rate. Budget the premium into any India deployment that cannot use a global endpoint, and price agent memory and session storage in the same region. Teams that model everything at the global rate and in USD will under-forecast both the endpoint premium and the rupee cost of a falling exchange rate.

How to keep the agent bill down

The pricing structure rewards a handful of engineering choices, and each one maps to a number on Google's own rate card. None of these is a trick. They are the levers a platform team controls once the July-to-September dates make every service a line item.

Match the model tier to the task. A support agent that classifies and retrieves does not need Gemini 3.1 Pro at $2/$12 per million tokens when Gemini 3 Flash at $0.50/$3 answers the same query. That is a four-to-eight-times swing on every turn, and it is the largest single lever most teams have. Reserve the Pro tier for reasoning that measurably fails on Flash.

Cache the stable context. Cached input on Gemini 3.1 Pro is $0.20 per million against $2.00 for fresh input, roughly a tenth of the cost. An agent that resends the same system prompt and tool definitions on every turn should be caching them. Keep each request under 200,000 tokens, because crossing that line charges every token in the request at long-context rates.

Gate grounding. The first 5,000 Google Search queries each month are free, then every additional thousand costs $14, and one user request can trigger several queries. Decide which agent turns are allowed to ground against the web and which answer from your own data at $2.50 per 1,000 prompts. An always-ground design is the fastest way to blow past the free tier.

Prune sessions and memory. From September 1, 2026, Sessions and Memory Bank both bill storage at $0.30 per GiB-month plus write operations at $0.085 per million. Reads are about three times cheaper than writes per vCPU-hour, so a read-heavy retrieval pattern with a retention limit on stored conversations costs less than one that writes memory on every exchange and keeps it forever. Set a time-to-live on session data and archive what you do not query.

Watch the endpoint and the tuning. Use a global endpoint wherever data-residency rules allow, because non-global endpoints add about 10% from July 1, 2026. Avoid a tuned model endpoint unless a base model genuinely cannot do the job, since a tuned endpoint costs 1.5 times the base rate.

How this compares to the wider market

The billing dates are part of a market-wide shift from free agent tooling to metered agent tooling. OpenAI began charging for agent usage in mid-2026, and other agent platforms increasingly meter runtime, memory, and tools as separate line items rather than bundling them into one fee, a pattern we cover in Bedrock AgentCore production scaling. Google's move to bill Skills Registry, Agent Gateway, Memory Bank, and Sessions puts the Gemini Enterprise Agent Platform on the same footing: the model is one cost among several, and the infrastructure that keeps an agent stateful and connected is now its own invoice.

FAQ

What is the Gemini Enterprise Agent Platform?

It is Google Cloud's platform to build, scale, govern, and optimise AI agents, launched as Gemini Enterprise in October 2025 and formerly called Agentspace. It is a standalone Google Cloud product, not a Workspace add-on, and it bills across three layers: per-seat subscriptions, per-million-token model charges, and per-hour agent infrastructure.

Which Gemini Enterprise charges start between July and September 2026?

Skills Registry billing begins July 1, 2026, and non-global endpoint pricing takes effect the same day. Agent Gateway becomes effective July 13. Semantic Governance Policies start August 1. Memory Bank and Sessions both begin billing September 1, 2026. Each meters on Agent Compute at $0.085 per vCPU-hour.

How much do Gemini models cost on the platform?

As of July 2026, Gemini 3.1 Pro costs $2 per million input tokens and $12 per million output tokens, with cached input at $0.20. Gemini 3.5 Flash is $1.50 and $9, Gemini 3 Flash is $0.50 and $3, and Gemini 3.1 Flash-Lite is $0.125 and $0.75.

What is Agent Compute and how is it priced?

Agent Compute is the per-hour meter for agent infrastructure, priced at $0.085 per vCPU-hour, with Agent Memory at $0.009 per GiB-hour. One vCPU-hour covers about 3 million read operations or 1 million write operations, and storage for memory, sessions, and skills is $0.30 per GiB-month. A monthly free tier applies per account.

How much do grounding and search queries cost?

Grounding with Google Search and Web Grounding for Enterprise include 5,000 queries per month free, aggregated across Gemini 3 models, then bill $14 per 1,000 search queries, with billing started January 5, 2026. One user request can trigger several queries. Grounding with your own data is separate at $2.50 per 1,000 prompts.

What do the Gemini Enterprise seat editions cost?

Independent trackers report list prices of $21 per user per month for Business, $30 annual or $35 flex for Standard, and $50 annual or $60 flex for Plus, with Frontline priced custom at a 150-seat minimum. Annual commitment is about 17% cheaper than flex, and compute consumption is billed on top of every seat.

Why is my India deployment more expensive?

From July 1, 2026, non-global endpoints carry roughly a 10% premium over global model rates. Regulated Indian entities under the DPDP Act 2023 often must keep personal data in-country, routing agents through regional endpoints such as Mumbai and paying that premium. Storage and session data held in-region are billed at the same regional rates.
