AI-powered video generation is improving at a breathtaking pace. In a short time, we’ve gone from blurry, incoherent clips to generated videos with stunning realism. Yet, for all this progress, a critical capability has been missing: control and Edits While generating a beautiful video is one thing, the ability to professionally and realistically edit it—to change the lighting from day to night, swap an object’s material from wood to metal, or seamlessly insert a new element into the scene—has remained a formidable, largely unsolved problem. This gap has been the key barrier preventing AI from becoming a truly foundational tool for filmmakers, designers, and creators. Until the introduction of DiffusionRenderer !! In a groundbreaking new paper, researchers at NVIDIA, University of Toronto, Vector Institute and the University of Illinois Urbana-Champaign have unveiled a framework that directly tackles this challenge . DiffusionRenderer represents a revolutionary leap forward, mov...

In this tutorial, we delve into Modin , a powerful drop-in replacement for Pandas that leverages parallel computing to speed up data workflows significantly. By importing modin.pandas as pd, we transform our pandas code into a distributed computation powerhouse. Our goal here is to understand how Modin performs across real-world data operations, such as groupby, joins, cleaning, and time series analysis, all while running on Google Colab. We benchmark each task against the standard Pandas library to see how much faster and more memory-efficient Modin can be. Copy Code Copied Use a different Browser !pip install "modin[ray]" -q import warnings warnings.filterwarnings('ignore') import numpy as np import pandas as pd import time import os from typing import Dict, Any import modin.pandas as mpd import ray ray.init(ignore_reinit_error=True, num_cpus=2) print(f"Ray initialized with {ray.cluster_resources()}") We begin by installing Modin with ...

In a strategic move to advance open-source development in medical AI, Google DeepMind and Google Research have introduced two new models under the MedGemma umbrella: MedGemma 27B Multimodal , a large-scale vision-language foundation model, and MedSigLIP , a lightweight medical image-text encoder. These additions represent the most capable open-weight models released to date within the Health AI Developer Foundations (HAI-DEF) framework. The MedGemma Architecture MedGemma builds upon the Gemma 3 transformer backbone, extending its capability to the healthcare domain by integrating multimodal processing and domain-specific tuning. The MedGemma family is designed to address core challenges in clinical AI—namely data heterogeneity, limited task-specific supervision, and the need for efficient deployment in real-world settings. The models process both medical images and clinical text, making them particularly useful for tasks such as diagnosis, report generation, retrieval, and agentic re...

Salesforce AI Research has introduced GTA1 , a new graphical user interface (GUI) agent that redefines the state-of-the-art in agentic human-computer interaction. Designed to autonomously operate in real operating system environments such as Linux, GTA1 addresses two critical bottlenecks in GUI agent development: ambiguous task planning and inaccurate grounding of actions . With a 45.2% task success rate on the OSWorld benchmark, GTA1 surpasses OpenAI’s CUA (Computer-Using Agent), establishing a new record among open-source models. Core Challenges in GUI Agents GUI agents typically translate high-level user instructions into action sequences—clicks, keystrokes, or UI interactions—while observing UI updates after each action to plan subsequent steps. However, two issues persist: Planning Ambiguity : Multiple valid action sequences can fulfill a task, leading to execution paths with varying efficiency and reliability. Grounding Precision : Translating abstract action proposals ...

In today’s AI-driven world, prompt engineering isn’t just a buzzword—it’s an essential skill. This blend of art and science goes beyond simple queries, enabling you to transform vague ideas into precise, actionable AI outputs. Whether you’re using ChatGPT 4o, Google Gemini 2.5 flash, or Claude Sonnet 4, four foundational principles unlock the full potential of these powerful models. Master them, and turn every interaction into a gateway to exceptional results. Here are the essential pillars of effective prompt engineering: 1. Master Clear and Specific Instructions The foundation of high-quality AI-generated content, including code, relies on unambiguous directives. Tell the AI precisely what you want it to do and how you want it presented. For ChatGPT & Google Gemini: Use strong action verbs: Begin your prompts with direct commands such as “Write,” “Generate,” “Create,” “Convert,” or “Extract.” Specify output format: Explicitly state the desired structure (e.g., “Provid...

Microsoft has officially open-sourced the GitHub Copilot Chat extension for Visual Studio Code (VS Code), placing a previously premium AI-powered coding assistant into the hands of developers—free of charge. Released under the permissive MIT license, the entire feature set that once required a subscription is now accessible to everyone. This shift represents a major milestone in making AI-enhanced developer tools widely available and paves the way for increased customization, transparency, and innovation in coding environments. Hosted on GitHub at microsoft/vscode-copilot-chat , the extension includes four core components: Agent Mode, Edit Mode, Code Suggestions, and Chat Integration. These components work together to create a highly interactive, context-aware coding assistant that goes beyond simple code completion. 1. Agent Mode: Automating Complex Coding Tasks The Agent Mode is designed to handle multi-step coding workflows autonomously. It goes far beyond autocompletion or stati...

Hugging Face just released SmolLM3 , the latest version of its “Smol” language models, designed to deliver strong multilingual reasoning over long contexts using a compact 3B-parameter architecture. While most high-context capable models typically push beyond 7B parameters, SmolLM3 manages to offer state-of-the-art (SoTA) performance with significantly fewer parameters—making it more cost-efficient and deployable on constrained hardware, without compromising on capabilities like tool usage, multi-step reasoning, and language diversity. Overview of SmolLM3 SmolLM3 stands out as a compact, multilingual, and dual-mode long-context language model capable of handling sequences up to 128k tokens . It was trained on 11 trillion tokens , positioning it competitively against models like Mistral, LLaMA 2, and Falcon. Despite its size, SmolLM3 achieves surprisingly strong tool usage performance and few-shot reasoning ability—traits more commonly associated with models double or triple its size...
