Robots Run Half-Marathon

ALSO : Google’s AI comeback

Hi Synapticians!

Hope you all enjoyed a wonderful Easter weekend! Whether you hunted for eggs or just enjoyed the long break, we're back with more AI excitement this week … 😁 

What do robot runners and tiny computer brains have in common? They both made a splash in AI this week! In Beijing, a bunch of humanoid robots actually joined human runners in a half-marathon. Pretty wild, right? They weren't trying to break speed records - they were testing if they could keep their balance, go the distance, and not run out of battery while dealing with real-world chaos. Some robots ran on their own, while others needed humans giving them directions from afar, but either way - we're getting closer to robots not just walking among us, but jogging alongside us!

For now, there's one arena where humans still clearly outshine their mechanical counterparts: sports. Physical competition has always been uniquely human territory, but how long will that last? Imagine a future Olympic Games with robot divisions, or mixed human-robot relay teams. Would it be thrilling to race against a humanoid that never gets tired? Or would it take the human spirit out of competition? As robots continue to develop better mobility, balance, and endurance, we might need to rethink what athletic competition means. Lots to consider as the line between human and machine achievements gets blurrier by the day!

Top AI news

1. Humanoid robots complete first-ever half-marathon in Beijing
In a world-first event, dozens of humanoid robots participated in a 21-kilometer half-marathon in Beijing alongside human runners. The race tested the robots’ endurance, balance, and battery life under real-world conditions. Some ran autonomously, others were remotely guided. The goal was not speed, but completion—pushing the boundaries of robotics integration into society. Engineers see this as a major step toward industrializing humanoid robots and preparing them for real-life applications.

2. How Google quietly took the lead in enterprise AI
Once seen as falling behind, Google has now taken the lead in enterprise AI. With its Gemini 2.5 model, custom TPUs, and a fully integrated stack, Google offers unmatched performance and efficiency. The company’s focus on infrastructure, agent ecosystems, and real-world business use cases has attracted over 500 enterprise clients. This article explains how Google’s quiet execution and end-to-end control have positioned it ahead of OpenAI and Microsoft in the AI race.

3. Microsoft’s BitNet: AI on a diet
Microsoft’s BitNet b1.58 2B4T is a new language model designed for extreme efficiency. Using only 1.58 bits per weight, it drastically reduces memory and energy consumption while maintaining performance comparable to much larger models. It introduces BitLinear layers and 8-bit activations, and was trained on 4 trillion words. With a memory footprint of just 0.4 GB, BitNet is ideal for local deployment. Microsoft also provides lightweight inference tools and plans to expand the model’s capabilities to support longer texts, more languages, and multimodal inputs.

Bonus. AI Struggles With Color
Researchers from the University of Maryland introduced COLORBENCH, a benchmark to test how well vision-language models understand color. The results show that even large models like GPT-4o struggle with basic color tasks, often performing better in grayscale. The study highlights structural limitations in current VLMs, especially in underpowered vision encoders. Chain-of-thought reasoning improves robustness, but more investment in visual components is needed. COLORBENCH is open source and aims to guide future improvements in multimodal AI.
