Google Gemini 2.5 Deep Think: Next-Gen AI with Superior Reasoning & Multimodal Power

Google's recent unveiling of the Gemini 2.5 Deep Think model marks a significant advancement in artificial intelligence, particularly in complex reasoning tasks. This latest iteration not only surpasses its predecessors but also outperforms competitors like OpenAI's o3 and Grok 4 in various benchmarks.

Enhanced Reasoning Capabilities​

A standout feature of Gemini 2.5 is its "Deep Think" mode, which allows the model to evaluate multiple potential answers before delivering a response. This approach enhances accuracy and depth in problem-solving, setting a new standard in AI reasoning. Demis Hassabis, head of Google DeepMind, highlighted that Deep Think utilizes cutting-edge research in thinking and reasoning, including parallel techniques. (techcrunch.com)

Benchmark Performance​

Gemini 2.5 Pro demonstrates superior performance across a range of benchmarks:

• Humanity's Last Exam (no tools): Achieved a score of 18.8%, outperforming OpenAI's o3-mini at 14% and Claude 3.7 Sonnet at 8.9%. (datacamp.com)
• GPQA Diamond (single attempt): Scored 84.0%, leading over Grok 3 Beta at 80.2% and o3-mini at 79.7%. (datacamp.com)
• AIME 2025 (single attempt): Recorded 86.7%, slightly ahead of o3-mini's 86.5%. (datacamp.com)

These results underscore Gemini 2.5's prowess in reasoning, mathematics, and science tasks.

Advanced Coding Proficiency​

In coding tasks, Gemini 2.5 Pro exhibits notable improvements:

• LiveCodeBench v5 (single attempt): Achieved a score of 70.4%, closely trailing o3-mini at 74.1%. (datacamp.com)
• Aider Polyglot (whole file editing): Scored 74.0%, indicating strong performance in code editing across multiple languages. (datacamp.com)

These enhancements make Gemini 2.5 a valuable tool for developers seeking efficient and accurate code generation and editing capabilities.

Multimodal and Long-Context Processing​

Gemini 2.5 Pro's ability to handle diverse data types and extended contexts is noteworthy:

• MMMU (multimodal understanding; pass@1): Scored 81.7%, surpassing Grok 3 Beta at 76.0% and Claude 3.7 Sonnet at 75%. (datacamp.com)
• MRCR (long-context reading comprehension; 128K context): Achieved 91.5%, significantly outperforming o3-mini at 36.3% and GPT-4.5 at 48.8%. (datacamp.com)

These capabilities enable the model to process and understand complex, multimodal inputs over extended contexts effectively.

Accessibility and Cost Efficiency​

Initially available to Gemini Advanced subscribers at $20 per month, Google has now made Gemini 2.5 Pro accessible to all users for free. Advanced subscribers continue to enjoy benefits such as higher request limits and longer context windows. (tomsguide.com)
