What Is Le Chaton Fat? The Fake Mistral AI Model Explained

Le Chaton Fat is a fake AI model, and that is the whole point. For about a week in June 2026, AI Twitter and Reddit were flooded with launch graphics, leaked benchmarks, and breathless threads about a new Mistral frontier model called Le Chaton Fat. The name mashes French and English together for “the fat kitten.” It had 30 trillion parameters, scored higher than every rival on charts that looked just real enough, and ran at a claimed 1,000 meows per second. None of it exists. There are no weights, no API, and no product page. This article explains what Le Chaton Fat actually is, where the joke came from, […]

GLM 5.2: Zhipu’s 1M-Context Open-Source Model Explained

GLM 5.2 arrived on June 13, 2026, and it lands with three headline numbers: a 744-billion-parameter Mixture-of-Experts design, a 1-million-token context window, and an MIT license that makes the weights free for anyone to download and run. Chinese AI lab Zhipu AI (operating as Z.ai) shipped it as a coding-first frontier model, and the timing was not subtle. It went public just two days after the US ordered Anthropic to cut foreign access to its Fable 5 and Mythos 5 models. This article breaks down what GLM 5.2 actually is, how it differs from the GLM 5.1 release in April, what the 1M-token context means in practice, and where it […]

Kimi K2.7 Code Review: Moonshot AI’s 1T Open-Weight Coding Model

Moonshot AI released Kimi K2.7 Code on June 12, 2026, and it is one of the largest open-weight coding models you can download right now. It packs 1 trillion total parameters, activates 32 billion of them per token, runs a 256K-token context window, and ships with open weights on Hugging Face under a Modified MIT license. The headline pitch is efficiency, with Moonshot claiming the model uses about 30% fewer reasoning tokens than the previous K2.6 while scoring higher on its coding tests. This is a coding-first, agentic model, built to plan, edit files, run tools, and debug across many steps rather than to chat. That focus matters, because the […]

Rio 3.5 Open 397B: A City Government Just Shipped a Frontier AI Model

The city government of Rio de Janeiro just released a frontier-class open AI model. It is built to go head to head with the best open systems on the planet. Rio 3.5 Open 397B comes from IplanRIO, the municipal IT company that runs Rio de Janeiro’s digital services. On its own benchmarks it edges out Alibaba’s Qwen 3.7 Plus on several tests. That is not a typo. A city hall shipped a 397-billion-parameter model under a fully open license. Here is the honest version of the story. Rio 3.5 Open 397B is not built from scratch. It is fine-tuned from Qwen 3.5-397B-A17B, Alibaba’s open base model, with a new reasoning […]

Greenest AI Ranked 2026 thumbnail featuring bold yellow and white headline text beside glowing icons for ChatGPT, Google Gemini, Claude, and an eco-friendly AI leaf on a dark blue, purple, and green neon background.

Most Eco-Friendly AI in 2026: Which AI Is Actually Green?

A single text prompt to Google Gemini uses about 0.24 watt-hours of electricity and roughly 0.26 millilitres of water, around five drops. A comparable ChatGPT query sits near 0.34 watt-hours, meaning Gemini uses roughly 29% less energy per prompt. Those numbers sound tiny, but multiply them by billions of prompts a day and the footprint of everyday AI use becomes very real. So which AI is the most eco-friendly, and is switching to a dedicated “green” AI tool actually worth it? This guide ranks the mainstream models by energy and water use, breaks down the dedicated eco-friendly AI tools worth knowing, and shows you the single most effective thing you […]

Amazon Rufus is now Alexa for Shopping thumbnail featuring bold yellow and white headline text beside a glowing smartphone with Amazon’s shopping interface, an Alexa-powered search bar, and shopping products on a dark blue and purple background.

Amazon Rufus Is Now Alexa for Shopping: What Changed and How to Use It

On May 13, 2026, Amazon retired the standalone Rufus chatbot and replaced it with Alexa for Shopping, a new agentic AI assistant built straight into the main Amazon search bar. Rufus had helped over 300 million customers in 2025 research and compare products, so this is not a quiet tweak. The separate Rufus chat window is gone, and its recommendations and product expertise now live inside a single, more capable assistant. If you opened the Amazon app recently and noticed Rufus missing, you did not lose anything. This guide explains exactly what happened to Rufus, what Alexa for Shopping can do, how to access it for free, and whether the […]

Nex-N2-Pro: The Free Open-Source Model That Goes Toe-to-Toe With GPT-5.5

A Chinese AI lab just released a free model that scores 80.8 on SWE-Bench Verified and 75.3 on Terminal-Bench 2.1, putting it in the same league as GPT-5.5 and Claude Opus 4.7 on real coding work. It is called Nex-N2-Pro, it dropped on June 2, 2026, and it costs nothing to download. The model comes from Nex AGI, ships under a permissive Apache 2.0 license, and is built specifically for agentic tasks like writing code, calling tools, and running long, multi-step workflows on its own. This is one of the clearest signs yet that open-source AI has caught up with the frontier on the tasks developers actually care about. In […]

WWDC 2026 Recap: Siri AI, the Google Gemini Deal, and Your New Default-AI Choice

Apple just reset its entire AI strategy at WWDC 2026. In a keynote on June 8, the company rebranded Siri as Siri AI, built it on a new generation of Apple Foundation Models developed with Google Gemini, shipped iOS 27 and macOS 27 “Golden Gate,” and, in the move that matters most for you, opened a new Extensions framework that lets you set Claude, ChatGPT, Gemini, or Grok as the default AI across the system. It was also Tim Cook’s final keynote as CEO before John Ternus takes over on September 1, capping it as the biggest AI shift in Apple’s history. The headlines have focused on Siri and the […]

Thumbnail for “Is AI Bad for the Environment?” showing a glowing digital Earth with circuit-board patterns and an AI chip embedded into the planet. Large yellow and white text asks “Is AI Bad for the Environment?” against a dark blue and purple tech background.

Is AI Bad for the Environment? The Real 2026 Answer

Yes, AI is bad for the environment, and the numbers are no longer up for debate. Global data-center electricity use is set to jump from 415 TWh in 2024 to roughly 945 TWh by 2030 per the International Energy Agency, mostly because of AI. Cornell researchers project AI servers alone will emit 24 to 44 million metric tons of CO₂ and consume 731 to 1,125 million cubic meters of water per year by 2030. That is equivalent to adding 5 to 10 million cars to U.S. roads and matching the household water use of 6 to 10 million Americans. That is the bad news, and it is real. The longer […]

Futuristic tech cover for MiniMax M3 showing a glowing AI chip, yellow “MINIMAX M3” headline, and the subtitle “China’s new frontier model” on a dark neon background with red graphic accents.

MiniMax M3 Is Here With Frontier Coding, 1M Context, and Native Multimodality

On June 1, 2026, MiniMax officially released M3, the Shanghai lab’s next flagship language model, and it shipped exactly as promised. The model that spent weeks as an architecture teaser is now live, and the pitch turned out to be real: frontier-level coding, a 1-million-token context window, and native multimodality, all in one open-weight model. MiniMax calls it the first and only open-weight model to bring all three together. The architecture story we covered before launch held up. M3 is built on the new MiniMax Sparse Attention (MSA) design, the same sparse attention the company had killed in its M2 generation and brought back for M3. You can use it […]
