How Gemini 1.5 Pro and Grok 3 differ
What the numbers mean in practice when choosing between Gemini 1.5 Pro and Grok 3.
-
Grok 3 is 14% cheaper on input tokens ($3 vs $3.5 per million), which adds up quickly in document-heavy workloads.
-
Gemini 1.5 Pro is 53% cheaper on output tokens ($7 vs $15 per million) - the bigger factor for tools that generate long documents.
-
Gemini 1.5 Pro's 1M tokens context window is roughly 7.6x larger than Grok 3's 131.1K tokens, so it can work across bigger codebases, contracts, or archives in one pass.

- Enables faster training, lower latency, and more efficient serving.
- Dramatically improves scalability and inference speed.
6. Exceptional in-context learning capabilities
- Learns new tasks directly from long prompts without fine-tuning.
- Demonstrated by learning to translate a low-resource language (Kalamang) from a grammar manual.
7. High-fidelity multimodal understanding
- Reads, analyzes, and reasons about long PDFs, code repositories, images, and videos together.
- Enables new classes of applications: legal analysis, scientific review, codebase audits, long-form content generation, etc.
8. Safety and reliability first
- Undergoes extensive ethics, safety testing, and red-teaming.
- Improved representational safety and reduced hallucinations compared to previous generations.
9. Available for developers and enterprises
- Accessible via AI Studio and Vertex AI.
- Supports future pricing tiers for expanded context windows.
- Designed for real enterprise-scale workloads.
10. Widely capable mid-size model
- Positioned between Gemini Pro and Gemini Ultra generations.

FAQs
Gemini 1.5 Pro is generally cheaper: $3.5 input / $7 output per million tokens, versus $3 / $15 for Grok 3. Actual cost depends on how many tokens your workload reads and writes.
Gemini 1.5 Pro has the larger context window at 1M tokens, compared to 131.1K tokens for Grok 3. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
