The team behind Qwen has launched their chatbot.

In addition to open-source models from all the Qwen model families, they also offer proprietary MoE (Mixture of Experts) models. Their flagship general-purpose model is Qwen2.5-Plus, while Qwen2.5-Turbo is their long-context model, capable of handling up to 1 million tokens of context. There's also Qwen2-VL-Max, which seems to be just Qwen2-VL 72B—though that's not confirmed.

Feature-wise, it's quite solid for an early release. It includes artifacts, document uploads, and image input capabilities. A standout feature, which I haven’t seen outside of Chatbot Arena, is the ability to send the same prompt to multiple models (up to three) simultaneously. However, this feature is still rough around the edges—you can't seamlessly continue the conversation with just one of the models afterward, which their interface doesn’t currently support.

Coming soon, the chatbot is expected to integrate search and image generation capabilities. It will be interesting to see whether they’ll use FLUX again or develop their own solutions. We'll have to wait and see.

The service is entirely free, similar to Mistral and DeepSeek. Their goal isn’t to profit from subscriptions but to promote their API and gather additional fine-tuning data. For those concerned about privacy, Anthropic’s Claude remains the only option where chat data isn’t used for training.

Choosing the best AI platform can feel overwhelming, but this chart makes it easier to see where each option stands in terms of speed, responsiveness, and cost.

In the green-shaded "most attractive quadrant," you can find platforms that offer a strong balance of fast response times and high output speed. Cerebras stands out as one of the fastest options here — it’s designed for quick AI responses, which makes it ideal for things like real-time chatbots or interactive applications. However, it comes at a higher cost, as shown by its larger size on the chart.

For a more budget-friendly approach, Google Vertex and Perplexity seem like good middle-ground options. They offer decent speed and responsiveness without the steep cost, so they’re better suited for projects where a balance of performance and cost matters.

Overall, this chart shows the trade-offs between AI speed, latency, and price, helping anyone get a sense of what might work best for their needs, from high-speed applications to cost-effective solutions.

The article emphasizes the need to make teaching a more attractive profession to address the global shortage of teachers. It suggests that pay, working conditions, and the value placed on teachers by society play a crucial role in recruitment and retention. Quick fixes like bursaries and performance bonuses are ineffective. Instead, the focus should shift to raising the status of teaching, increasing resources, and improving student behavior to attract more graduates to the field. Countries like Finland and Singapore, where teachers are more respected, face fewer shortages.

At first glance, this diagram looks like a roadmap to the entire universe of numbers, a beautifully layered structure that reveals how different number sets relate to one another. It’s like peeling back the layers of mathematics, starting from the most basic building blocks and working your way up to the more complex, abstract concepts that shape higher-level math.

At the base of this number hierarchy, we see natural numbers (N) — the counting numbers that we first encounter in childhood, like 1, 2, and 3. As you move outward, you see the familiar integers (Z), which expand the natural numbers by including negatives, like -1, -2, -3. Then come the rational numbers (Q), which fill in the gaps with fractions, such as ½ and -2/3.

But mathematics doesn't stop at the rationals. There are irrational numbers, like √2, that can’t be expressed as simple fractions but still fall within the realm of real numbers (R) — numbers we can locate on the number line. The transcendental numbers, like π and e, push things even further, representing numbers that transcend algebraic equations.

Then we get into more intriguing territory: imaginary numbers, which involve i, the square root of -1. Suddenly, we’re in the world of complex numbers (C), where numbers combine both real and imaginary components, like 1 + i or πi. This is where algebra, geometry, and complex analysis come together.

This diagram isn't just a classification system—it's a snapshot of mathematical elegance. Each category builds on the previous one, showing how mathematics flows from the simplest natural numbers all the way to the intricate, mind-bending realm of complex numbers. It's a reminder that math is both deeply structured and infinitely expansive, a system with layers to uncover and explore.

Nearly 15 years ago, a small JetBrains engineering team took on an ambitious challenge: creating a new programming language to stand alongside industry giants. At the time, Java dominated the tech landscape, powering millions of projects but showing signs of stagnation, with few significant updates and a lack of modern features. Engineers everywhere were eager for fresh solutions.

Various developers tried to reshape the JVM ecosystem with new languages, sensing a fleeting opportunity to build something transformative. Kotlin was born out of this drive for change. But what factors fueled Kotlin’s rise, and what challenges did its creators face to secure its place in the tech world? This documentary tells the story straight from the innovators themselves.

I also want to share a visualization of the planned catch of the booster by Mechazilla (yes, that's what the tower is called).

As you watch the video, keep in mind that the silver stainless steel tank stands at 71 meters tall (equivalent to a 24-story building) and weighs around 200 tons without fuel. The booster needs to gently and precisely fly into the arms of Mechazilla, after descending from a height of over 100 KM.
