Last updated on July 10, 2025
Grok 4 is xAI’s most advanced large language model, representing a step change from Grok 3. With a 130K+ context window, built-in coding support, and multimodal capabilities, Grok 4 is designed for users who demand both reasoning and performance.
If you’re wondering what Grok 4 offers, how it differs from previous versions, and how you can start leveraging its features—this post covers everything you need to know.
Grok 4 is the flagship model by xAI, announced on July 10, 2025. It introduces:
Partial API access is already available, and the developer community is actively exploring Grok 4’s new endpoints.
Here are the key features confirmed or strongly anticipated:
| Feature | Grok 4 |
|---|---|
| Reasoning Approach | Axiom-based, first-principles logic |
| Context Window | 130,000 tokens |
| Modalities | Text (currently available), Vision & Image Generation (coming soon) |
| Coding Support | Grok 4 Code with Cursor IDE integration and built-in file editor |
| Image Generation | Built In(planned) |
| Access | Partial API currently available |
| Open Source | Lighter community variants planned for late 2025 |
| Scalability | GPU-backed infrastructure (Colossus supercomputer) |
| API Feature | Grok 4 API |
|---|---|
| API Endpoint | api.x.ai (us-east-1) |
| Model Name | grok-4-0709 |
| Aliases | grok-4, grok-4-latest |
| Context Window | Up to 256,000 tokens (standard pricing up to 128K) |
| Pricing – Input | $3.00 per 1M tokens |
| Pricing – Cached Input | $0.75 per 1M tokens |
| Pricing – Output | $15.00 per 1M tokens |
| Rate Limits | 60 requests/minute, 16,000 tokens/minute |
| Function Calling | Supported |
| Structured Outputs | Supported (JSON and organized formats) |
| Availability | Partial API, public access coming soon |
Using cached tokens can lower your costs significantly.
Grok 4 itself will remain proprietary, accessible via xAI’s API and integrated platforms only. However, xAI can release smaller, open-source variants later in 2025, facilitating broader research and development:
| Feature | Grok 3 | Grok 4 |
|---|---|---|
| Reasoning Approach | Enhanced logical reasoning | Significantly enhanced logical reasoning |
| Multimodality | Text only | Text, vision & image-generation |
| Coding Assistance | Basic suggestions | Advanced IDE integration and live file editing |
| Context Length | 32K tokens | 130K tokens |
| Accuracy & Bias Reduction | Moderate accuracy, higher hallucination rate | Significantly enhanced accuracy, reduced hallucination rate |
| Performance | Moderate speed | High-throughput via GPU clusters |
Grok 4 is a major step forward in AI technology, offering improved logical reasoning, multimodal outputs, and advanced coding tools in one unified model. It provides clear benefits for diverse tasks, from creative projects to technical work.
Keep an eye on xAI’s updates to fully benefit from Grok 4 and discover how this advanced AI model can improve your workflow.
Boost your productivity with smarter reasoning, easy-to-use coding tools, and reliable performance.
