While OpenAI’s GPT-4 remains slightly stronger in some NLP tasks, Tülu 3 45B is closing the gap rapidly—all while remaining fully open-source.

Safety & Ethical Considerations

One of the biggest criticisms of open-source AI is the lack of safety controls. However, AI2 has taken this concern seriously. They have implemented:

  • Advanced content filtering to block harmful responses.
  • Strict preference tuning to ensure ethical AI behavior.
  • A multi-stage training process to eliminate biases and misinformation.

Their internal tests show that Tülu 3 45B outperforms DeepSeek V3, Llama 3.1, and Nous Hermes 3 in rejecting harmful prompts, making it one of the safest open-source models available.

What’s Next? The Future of Open-Source AI

Google Creates a Digital Fruit Fly That Thinks, Moves, and Sees Like the Real Thing In a stunning leap forward for both artificial intelligence and biology, Google has developed a fully digital fruit fly—a virtual insect that lives inside a computer and behaves just like its real-world counterpart. This digital creation walks, flies, sees, and responds to its environment with lifelike precision. The journey began with a meticulous reconstruction of a fruit fly’s body using Mojo, a powerful physics simulator. The result was a highly detailed 3D model that could mimic the fly's physical movements. But a body alone doesn’t make a fly—it needed a brain. To create one, Google's team collected massive volumes of video footage of real fruit flies in motion. They used this data to train a specialized AI model that learned to replicate the complex behaviors of a fly—walking across surfaces, making sudden mid-air turns, and adjusting flight speed with astonishing realism. Once this AI br...

What Are We Really Feeding Our Minds? A Wake-Up Call for Indian Youth In the age of social media, trends rule our screens and, slowly, our minds. Scroll through any platform and you’ll see what truly captures the attention of the Indian youth: food reels, cinema gossip, sports banter, and, not to forget, the ever-growing obsession with glamour and sex appeal. Let’s face a hard truth: If a celebrity removes her chappal at the airport, it grabs millions of views in minutes. But a high-quality video explaining a powerful scientific concept or a motivational lecture from a renowned educator? Struggles to get even a few hundred likes. Why does this matter? Because what we consume shapes who we become. And while there’s nothing wrong with enjoying entertainment, food, or sports — it becomes dangerous when that’s all we focus on. Constant consumption of surface-level content trains our minds to seek instant gratification, leaving little room for deep thinking, curiosity, or personal growth...

REAL GOD of GODs

In 2016, Amazon proudly unveiled its “Just Walk Out” technology, marketed as a groundbreaking artificial intelligence (AI) system that could detect and charge customers for items they picked up without human intervention. The reality, however, was far less high-tech than advertised. Behind the scenes, over a thousand overseas workers—primarily based in India—were manually monitoring and supporting the system. This revelation exposed a broader truth: the remarkable rise of AI is built not just on algorithms and computing power, but on the backs of an invisible human workforce. The Human Side of AI Contrary to popular belief, the engines that power virtual assistants, recommendation systems, and machine translation are not entirely autonomous. They require extensive human input to function effectively. This input often comes from data workers responsible for labeling images, transcribing audio, and categorizing content. While Silicon Valley giants present AI as a product of sophisticat...
