Gemini vs Grok (2026): $19.99 AI Pro vs $30 SuperGrok, Both 1M Context

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 4.3 is the better pick if you need live information off X, want fewer content guardrails, or run output-heavy API workloads where its $2.50 per million output tokens beats Gemini'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

On the API Grok 4.3 is materially cheaper, especially on output: $2.50 per million versus Gemini's $12.00 under 200K tokens. Both providers double their per-token rate once a prompt crosses 200K input tokens, and both offer roughly 90% cached-input discounts and 50% batch discounts. For high-volume, output-heavy generation, Grok wins on cost. For mixed-media or document pipelines, Gemini's capabilities can justify the premium.

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.

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?

Both ship 1M context and sit near the top of LMArena. Gemini 3.1 Pro leads multimodal, long-context retrieval, Google integration, and scores 77.1% on ARC-AGI-2. Grok 4.3 leads live X data, has an on-device code-running computer plus Skills, and 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, at $2.50 per million versus Gemini's $12.00.

Do they have the same context window?

Yes. Both Gemini 3.1 Pro and Grok 4.3 ship a 1M token window. 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 and December 2025 cutoff are its real-time edge.

Which is better for multimodal?

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

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).
