Grok 4 vs Grok 3: What's the Difference
Compared with Grok 3, Grok 4 has made many improvements in its performance. It can process multimodal input, including text, images, and speech, with large-scale parallel computing. Grok 3 mainly tackles text-based input and generation. Dive into this comparison table to see how benchmark accuracy, reasoning, and architecture differ from each other.
Benchmark Scores & Testing:
Benchmarks serve as the most straightforward indicators of raw performance. The Grok 4 model, especially the Grok 4 Heavy version, outshines Grok 3 in academic, reasoning, and coding assessments. Here’s a detailed overview of benchmark scores for the two models:
- Grok 3: basic performance
- Grok 4: more capable in coding, science, and complex reasoning
Multimodal Capability
In multimodal capability, Grok 3 is similar to other AI models that mainly focus on text generation, and it is integrated with part of the data of the X platform. After the upgrade, what Grok 4 does is beyond just text generation. It adds native tools to use with plans for image input and voice interaction in the future.
- Grok 3: Basic integration with X data
- Grok 4: Native tool use, plugin integration, and real-time web access; expanding voice and vision features.
Context Window Expansion
Context window is also a key factor to measure the performance of Grok 4 and Grok 4, as it determines how much input the model can process at once. Grok 4 handles 256000 tokens, while Grok 3 is only able to process 128k tokens. Therefore, Grok 4 can deal with larger codebases.
- Grok 3: Up to 128k tokens (depending on version)
- Grok 4: Supports up to 256k tokens
Speed and Responsiveness
When you are texting an AI model, response time is also very important. Usually, the faster it is, the better the user experience will be. Grok 4 is designed to handle lightweight tasks, so it is much faster. However, Grok 4 requires heavier, more demanding capabilities, so it might take longer than Grok 3.
- Grok 3: faster due to light-weight task dealing
- Grok 4: slower due to accurate and layered processing.
Coding & Developer Assistance
Designed to be a serious coding assistant, Grok 4 works better for advanced tasks like logic-heavy code and debugging. As for Grok 3, it delivers relatively basic help with explanations and simple code snippets. In this aspect, Grok 4 is more developer-friendly, and Grok 3 is more beginner-friendly.
- Grok 3: relatively limited programming assistance.
- Grok 4: offer a dedicated code model, and Grok 4 heavy can process real-time code generation and testing.
Grok 4 vs Grok 3 in Pricing
In terms of price, Grok 3 is more cost-effective for its basic features, while Grok 4 comes at a higher price point due to its advanced capabilities and computational needs. Here, we compare the cost of the 2 models from base access, API costs, and premium features:
Grok 4 | Grok 3 | |
👉Base Access | X Premium+ ($16/month) | X Premium ($8/ 8/month) |
✴️API Costs | $0.15/1K tokens | $0.10/1K tokens |
🔐Premium Features | SuperGrok Heavy ($300/month) | Standard features |
Obviously, Grok 3 is suitable for small and medium businesses with a more affordable price, and Grok 4 can be used by large enterprises with high demands.
