How does Grok 4's performance compare to other models available on Perplexity?

Perplexity offers access to several advanced AI models, including Grok 4, GPT-4.1, Claude 4.0 Sonnet/Opus, and Gemini 2.5 Pro. Their performance varies based on task type, reasoning, coding, and other specialized capabilities.

• Grok 4 excels at complex reasoning and planning, beating out Gemini 2.5 Pro and often surpassing Claude 4 Opus in benchmarks such as GPQA Diamond, where Grok 4 achieved a record 88% versus Gemini’s 84%12.

• In general intelligence indices and challenging benchmarks, some independent analyses named Grok 4 “the leading AI model” as of July 2025, especially in reasoning-heavy tasks23.

• For tasks requiring up-to-date insights from X (Twitter) or web data, Grok 4 stands out due to its deep integration with live X data, offering advantages in real-time trend analysis and market research—tasks where no other model can currently match its “X-factor”3.

• Claude 4 Sonnet/Opus consistently outperforms Grok 4 in coding challenges, producing cleaner, more complete code with fewer errors and superior debugging capabilities14.

• Grok 4 outperforms Gemini 2.5 Pro in coding, but lags behind Claude 4 Sonnet/Opus, whose methodical approach and clear explanations make it the preferred choice for complex coding, debugging, and content generation154.

• GPT-4.1 offers rapid responses with good accuracy, excelling in simpler, quick problem-solving scenarios. Claude 4 Sonnet’s deeper explanations are especially helpful for those learning new coding concepts5.

• Grok 4 is often slower compared to other models when handling complex queries, with some users reporting gradual sentence rendering and latency on Perplexity6.

• Gemini 2.5 Pro is recognized for its value and balanced speed, especially for price-to-performance. Its multimodal support offers unique advantages on tasks involving images or system diagrams15.

• Grok 4 uniquely dominates tasks involving real-time social insights and rapid analysis of live conversations, particularly when asked to perform tasks like “search X for trends.” This is an exclusive feature not matched by GPT-4.1, Claude, or Gemini3.

• For market research and customer feedback analysis using real-time data, Grok 4 consistently achieves top marks3.

• Grok 4 tends to be less expensive than Claude 4 Opus at large context windows, but Gemini 2.5 Pro takes the lead for best price-to-performance ratio overall1.

• Grok 4 is best for complex reasoning and market analysis leveraging X data.

• Claude 4 Sonnet/Opus remains the top performer for coding and technical development.

• Gemini 2.5 Pro offers the best balance of multimodal capabilities and value.

• Speed may be a drawback for Grok 4 on Perplexity, and Claude 4 Sonnet's depth in explanations and debugging outshines its peers for developers.

The best choice depends on your primary use case: for reasoning and real-time web/X research, Grok 4 is the top pick; for coding, Claude 4 Sonnet/Opus is preferred; for value and multimodal tasks, Gemini 2.5 Pro leads the pack153.
