This week in tech, AI research assistants are flexing their muscles, and the latest benchmarks show that OpenAI's newest Deep Research agent is both impressive and flawed. Will AI truly replace human researchers anytime soon? We dive into the data to find out.
OpenAI’s Deep Research Agent: Smarter but still missing common sense
The rise of AI-powered research—how it compares to human experts
Cost vs. Performance: Is premium AI research worth the price?
Let’s get into the details!
AI Research Assistants Are Becoming More Capable

OpenAI's Deep Research agent, powered by GPT-3.5-turbo, is showing impressive gains in specialized research tasks. It now achieves a 72-73% accuracy rate in benchmark tests, a massive leap from GPT-4’s 15% performance just nine months ago. However, it still falls short of human experts, who maintain a 92% accuracy rate.
✅ Key Data Points:
Guia Assistant Benchmark: 89% accuracy on basic research tasks, but only 67% on complex regulatory analysis.
Code Competitions: AI ranks in the 90th percentile, while humans dominate the 99th percentile.
Newsletter Analysis: OpenAI’s agent successfully identified high-impact articles at 100% accuracy, outperforming competitors.
📌 Meta Trend: AI’s rapid progression in research automation is part of a broader trend in knowledge work automation.

AI research tools are powerful but costly. OpenAI’s Deep Research Pro costs $200/month for 100 queries, significantly more than competitors like DeepSeek R1 (free) and Google’s Gemini Advanced ($20/month).
✅ Key Data Points:
DeepSeek R1 struggles with reliability, achieving only 15% accuracy.
Gemini Advanced trails with a 29% accuracy rate, returning false negatives in 100% of newsletter queries.
OpenAI leads in accuracy, but at a steep price.
📌 Meta Trend: The AI arms race is driving up costs, making premium research tools less accessible to smaller businesses and independent researchers.
AI Struggles with Common Sense and Spatial Reasoning

While AI models excel in structured research tasks, they still struggle with real-world reasoning. OpenAI’s Deep Research agent failed 100% of novel physical simulation problems and had a 42% error rate in mechanical advantage calculations.
✅ Key Data Points:
AI correctly identified 18/20 drug interaction scenarios, showing promise in medical applications.
AI-generated GDPR-compliant legal documents for three EU jurisdictions.
0% success rate in spatial reasoning tests.
📌 Meta Trend: AI’s struggle with physical and common sense reasoning suggests long-term limitations in its ability to replace human intuition.
