PagedAttention vs. RadixAttention: Optimizing LLM KV Cache Management

Janvi Kumari — Fri, 21 Aug 2026 10:42:03 +0000

Modern LLMs rely on quantization, pruning, distillation, and faster attention kernels, but production performance often depends most on KV cache management. As context windows grow, the cache consumes significant GPU memory, limiting concurrency, throughput, and latency. Two breakthroughs transformed this challenge: PagedAttention improves memory allocation, while RadixAttention enables efficient prefix reuse. Together, these techniques make […]

How to Remove Claude Watermarks from Text, Code, and Files

Vasu Deo Sankrityayan — Wed, 19 Aug 2026 05:52:55 +0000

Claude now marks AI-generated content. But it does not mark everything the same way. Anthropic currently uses embedded watermarks for text and signed C2PA provenance metadata for supported files. Code sits somewhere in between: it is still text, but its structure gives the watermark fewer places to work. I went into detail about Claude’s watermarks […]

How to Add Skills in Agents using LangChain

Mounish V — Tue, 18 Aug 2026 09:17:35 +0000

Ever wondered how ChatGPT, Gemini, and other chat interfaces generate PDFs, PowerPoints, and more when all they have under the hood is an LLM? The trick isn’t a smarter model. It’s something simpler: skills which are instructions an agent loads only when needed. Next, let’s explore how skills work using LangChain and how they can make […]

7 Kimi K3 Features That Make Every Other Model Feel Outdated

Riya Bansal — Mon, 17 Aug 2026 17:17:11 +0000

Developers launch new models every week, but most barely change how you work. Kimi K3 is different—not because of benchmark charts, but because of a few small API changes that fundamentally affect how you use it. The first is reasoning_effort, which defaults to maximum, alongside 131,072 max_completion_tokens. Ask K3 to rename a variable, and it […]

How to Install Codex CLI: A Step-by-Step Guide

Vasu Deo Sankrityayan — Sat, 15 Aug 2026 10:30:00 +0000

If you have already used Codex in ChatGPT, the Codex CLI will feel familiar. It brings the same AI assistance directly into your local development environment, where it can work with your repository, shell, tests, and other tools. Installation takes only one command, but the setup choices that follow are worth reviewing carefully. In this article, you’ll […]

NVIDIA Nemotron 3.5 Lightning: The AI Agent Workhorse

Harsh Mishra — Fri, 14 Aug 2026 11:08:54 +0000

Long-running AI agents often spend most of their time on routine execution rather than difficult reasoning. After making a plan, they may perform hundreds of tool calls, file reads, validations, commands, and formatting steps, so using a frontier reasoning model for every action can become unnecessarily slow and expensive. NVIDIA’s Nemotron 3.5 Lightning takes a […]

How Baidu Unlimited-OCR Works: Solving Long-Document Transcription

Shaik Hamzah — Thu, 13 Aug 2026 12:10:18 +0000

About a month ago, Baidu (often called the “Google of China”) introduced Unlimited-OCR, an advancement over DeepSeek OCR. The model was designed to transcribe long, multi-page documents with high accuracy while delivering fast and stable inference. Unlike conventional vision-language OCR systems, Unlimited-OCR addresses a major bottleneck in long-document transcription: the rapidly growing Key-Value (KV) cache, […]

Why You Shouldn’t Always Trust LLMs as Judges: Understanding Bias in Automated Evaluation

Soumil Jain — Wed, 12 Aug 2026 10:31:00 +0000

In the rush to automate evaluation, from grading student code to ranking research papers, we have embraced Large Language Models as judges. They are fast. These units are cheap. They scale. However, at a workshop at DHS 2026, Bhaskarjit Sarmah made a point that stuck with me: “you can’t trust LLM as a judge. I […]

Claude Now Watermarks Everything It Makes

Vasu Deo Sankrityayan — Tue, 11 Aug 2026 12:36:46 +0000

First, pick the line that applies to you. Since August 2nd, 2026, Claude marks all content during generation. For instance, text receives a hidden watermark, while files receive a signature. Anthropic committed to the EU AI Act’s Code of Practice on Transparency of AI-Generated Content. Consequently, all content generated by Claude models will carry a […]

How to Install Claude Code: A Step-by-Step Guide

Vasu Deo Sankrityayan — Mon, 10 Aug 2026 18:20:22 +0000

You have probably heard by now. Claude Code burns through usage limits! But most of us live in the web app… distant from the terminal app, around which the buzz is about. Maybe that was enough to make you curious. Maybe you already knew exactly what it was and just want it running on your […]
