Gemini vs Grok (2026): $19.99 AI Pro vs $30 SuperGrok, Grok 4.7 vs Gemini 3.1 Pro

The Short Answer

Gemini 3.1 Pro is the better default for most people: it is cheaper at the consumer tier ($19.99/mo vs $30/mo), built multimodal, and embedded across Gmail, Docs, Drive, and Search. Grok is the better pick if you need live information off X, want fewer content guardrails, or run output-heavy API workloads where Grok 4.7's $6 per million output tokens beats Gemini 3.1 Pro's $12.

On raw capability they are close. Gemini 3.1 Pro scores 77.1% on ARC-AGI-2, more than double Gemini 3 Pro on that benchmark. Grok 4.1 Thinking held the #1 overall spot on LMArena Text Arena at 1483 Elo. What separates the two is design intent, not a points gap.

Consumer Pricing and Tiers

Gemini is cheaper across the board at the consumer tier. AI Pro is $19.99/mo against SuperGrok at $30/mo, and Gemini adds a $4.99/mo AI Plus tier that Grok has no answer to. Google reduced the top AI Ultra price from $250 to $200/mo while keeping the same capabilities, including 20x higher usage limits versus Pro.

AI Pro bundles Deep Research, Veo 3.1 video generation, a 1M-token context window, and 1,000 Google Flow credits. AI Ultra adds Deep Think, Gemini Spark (US and English only), and 10,000 to 25,000 Flow credits. On the Grok side, SuperGrok Heavy adds Grok 4 Heavy, the highest usage limits, and 16x AI agents on Expert mode.

Rate Limits

Both run compute-based, not fixed-message, limits. Gemini app usage factors in prompt complexity, features used, and chat length, and refreshes every 5 hours until you hit the weekly cap. Reaching the cap on the biggest models shifts you to smaller models until reset. AI Plus gives 2x the Free usage, AI Pro 4x, and AI Ultra up to 20x the Pro limit.

Grok's tiers scale the same way: SuperGrok unlocks higher rate limits and frontier model access, and SuperGrok Heavy gives the highest usage limits plus 16x agents on Expert mode. If you routinely hit caps, the higher tier on either side is the lever, not switching providers.

API Pricing

Input prices match at $2.00 per million under 200K tokens, and Grok 4.7 costs half as much on output ($6.00 versus $12.00). Gemini wins on cached input ($0.20 versus $0.50 per million) and offers a 50% Batch API discount that grok-4.7 does not support. Both providers raise per-token rates once a prompt crosses 200K input tokens. For output-heavy generation, Grok wins on cost. For long-context or cache-heavy pipelines, Gemini 3.1 Pro's 1M window and cheaper cache reads close the gap. If cost matters more than peak quality, Gemini 3.8 Flash lists at $0.75 input and $3.75 output per million through December 31, 2026, rising to $1.50 and $7.50 from January 1, 2027.

Benchmarks

Gemini 3.1 Pro's 77.1% on ARC-AGI-2 (verified) more than doubles Gemini 3 Pro's result on the same benchmark. Grok 4 Heavy was the first model to reach 50.7% on the text-only subset of Humanity's Last Exam and leads USAMO 2025 at 61.9%. Grok 4.1 Thinking held #1 overall on LMArena Text Arena at 1483 Elo, 31 points above the top non-xAI model. Both labs publish on different benchmark mixes, so treat cross-model rows as directional rather than head-to-head.

Image and Video Generation

For a consumer who wants video in the chat app, Gemini is the cheaper route: Google AI Pro at $19.99/mo includes Veo 3.1 and 1,000 Google Flow credits. For developers, xAI's Imagine API is priced per second of output, and since July 31, 2026 Grok Imagine Video 1.5 accepts text, image, and reference inputs with native 1080p for text-to-video and image-to-video. Grok Imagine Image 2.0 editing takes up to five source images per request.

Where Gemini Wins

Where Grok Wins

Data and Privacy

Gemini Apps training is on by default through the Keep Activity setting; turning Keep Activity off stops future chats from being used to improve Google AI. Audio, Gemini Live video, and screenshares are not used to improve services by default. Gemini activity older than 18 months is auto-deleted by default, and you can change that window to 3 or 36 months or turn it off. Human-reviewed chats are disconnected from your account and kept for 3 years.

xAI publishes its training-data handling separately; if you care about defaults, check the current X / xAI data settings before relying on either provider for sensitive content. On Gemini, the practical step is Settings, then turn off Keep Activity.

Pick by Task

Frequently Asked Questions

Is Gemini or Grok better in 2026?

Neither is broadly ahead. Gemini 3.1 Pro leads multimodal, long-context work with its 1M window, Google integration, and scores 77.1% on ARC-AGI-2. Grok leads live X data, and Grok 4.7 is cheaper on output-heavy API workloads. Pick by task.

Which is cheaper, Gemini or Grok?

Consumer: Gemini, with Google AI Pro at $19.99/mo versus SuperGrok at $30/mo (and a $4.99/mo AI Plus tier Grok has no answer to). API output: Grok 4.7, at $6.00 per million versus Gemini 3.1 Pro's $12.00.

Do they have the same context window?

No. Gemini 3.1 Pro has a 1M token window and Grok 4.7 has 500K. Both APIs bill prompts over 200K input tokens at a higher rate.

Which is better for real-time info?

Grok, via live access to X. Gemini integrates Google Search, but Grok's direct feed access is its real-time edge. On the xAI API, live data needs the Web Search or X Search tool turned on.

Which is better for multimodal?

Gemini, built multimodal with reliable long-context retrieval across audio, video, and image in one prompt.

Is Grok or Gemini better for video generation?

In the app, Gemini: Veo 3.1 comes with Google AI Pro at $19.99/mo. On the API, xAI prices Grok Imagine Video 1.5 from $0.05 per second, with native 1080p and reference-to-video.

Is SuperGrok worth it over Google AI Pro?

Only if live X data is central to your work. SuperGrok is $30/mo against $19.99/mo for Google AI Pro, and AI Pro also includes 5 TB of storage, Veo 3.1, Deep Research, and Gemini inside Gmail and Docs.

What is the most expensive plan for each?

Grok's SuperGrok Heavy is $300/mo (adds Grok 4 Heavy and 16x agents on Expert mode). Gemini's AI Ultra starts at $99.99/mo with a $199.99/mo option (adds Deep Think, Gemini Spark, and up to 20x Pro usage).
