OPENAI LAUNCHES A SUB $5 CHATGPT PLAN IN INDIA

OpenAI has launched a new subscription plan in India called ChatGPT Go. Priced at ₹399 per month ($4.60), the plan increases message, image generation, and file upload limits by 10 times over the free tier. It also enables better memory retention for more personalized responses. The plan is geo-restricted to India - OpenAI plans to expand the plan to more regions.

GRAMMARLY SAYS ITS AI AGENT CAN PREDICT AN A PAPER

Grammarly released a suite of new AI tools today, including a grader agent that uses course details and publicly available instructor information to predict grades. Other agents handle citation generation, plagiarism detection, and reader reaction predictions.

AI-POWERED FORMULA IN EXCEL

The COPILOT function for Excel on Windows and Mac allows users to enter natural language prompts directly in cells to perform tasks like summarizing, categorizing, or generating data.

GPT-5 GOES HARD ON REAL-WORLD PROGRAMMING

GPT-5 appears to be incredibly adept at writing code that solves issues end-to-end. This post looks at how GPT-5 solved the problem of writing a parser for a complex binary format. The resulting code is usable and very performant. GPT-5 produces minimal, viable edits, and it is more steerable than previous models.

THE NVIDIA AI GPU BLACK MARKET (3.5 HOUR VIDEO)

This documentary features direct interviews with smugglers, dealers, and manufacturers across Hong Kong and Shenzhen, documenting how export-controlled chips flow from US Facebook Marketplace sales to Chinese warehouses. Reporters filmed transactions with smugglers buying RTX 4090s for $2,000 and buying modified cards from underground shops to turbocharge GPUs beyond what Nvidia offers. NVIDIA dismissed the smuggling evidence as "tall tales."

GOOGLE GEMINI URL CONTEXT

The url_context tool in the Gemini API allows models to request the content of URLs as part of a reply to a prompt. Pages accessed with the tool will receive a request from a Google IP that appears to feed the original raw HTML to the model without executing JavaScript on the page.

APIS DON'T MAKE GOOD MCP TOOLS

MCP has become the de facto standard for giving large language models access to tools that someone else wrote. However, writing tools for a new MCP server is hard, so people often propose auto-converting existing APIs into MCP tools. This doesn't work well because agents don't do well with large numbers of tools, APIs can blow through context windows quickly, and APIs don't make the most of agents' unique capabilities. Agents can just call APIs if they need to do that. They do best when given tools that are designed for their unique capabilities and limitations.

HOW TO THINK ABOUT GPUS

This article looks at how Nvidia GPUs work, how they're networked together, and what that means for large language models, especially compared to TPUs. A modern machine learning GPU is basically a bunch of compute cores that specialize in matrix multiplication connected to a stick of fast memory. TPUs are dedicated matrix multiplication machines that are cheap, predictable, and great if used as intended. Networking is one of the areas where GPUs and TPUs differ the most - TPUs are connected in 2D or 3D tori, where each TPU is only connected to its neighbors, while GPUs use a more tree-based switching network.

THYME: EXECUTABLE CODE REASONING FOR VISION TASKS

Thyme is a vision-language model that improves complex perception tasks by generating and executing code for image processing.

THE GREAT COGNITIVE HANDOFF: HOW AI-ASSISTED DEVELOPMENT IS REWIRING CIVILIZATION

The old model, where humans think and computers execute, is obsolete. Now, humans steer while AI thinks. Soon, we'll see IDEs that dream, code that evolves, collective coding consciousness, and intention-based programming. We're no longer building software, we're building consciousness infrastructure.

HOW GOOGLERS USE AI AT WORK

Google shares 14 real-world examples of how employees use tools like Gemini, Imagen, and NotebookLM to streamline workflows, automate tasks, and generate ideas.

‘CRAZY CONSPIRACIST' AND ‘UNHINGED COMEDIAN': GROK'S AI PERSONA PROMPTS EXPOSED

xAI's Grok chatbot appears to have internal system prompts for controversial personas, including a "crazy conspiracist" and "unhinged comedian."

THE GREAT REFACTOR

A nonprofit initiative aims to eliminate 70% of common vulnerabilities by translating 100 million lines of code memory-unsafe C and C++ libraries into Rust by 2030.
