Alibaba has released a new visual reasoning model, QvQ-72B-Preview, in December 2024, which integrates vision with text prompts to enhance visual reasoning capabilities.
The model is available for testing on Hugging Face Spaces and can be run locally using Prince Canuma’s mlx-vlm package, showcasing its open-source nature and accessibility.
Simon Willison's blog highlights the model's potential for creative applications, despite mixed results, and emphasizes its entertaining approach to problem-solving.
QvQ, Qwen's new visual reasoning model, requires 38GB of disk space and excels in providing detailed image descriptions but struggles with complex visual reasoning tasks.
The model's handling of sensitive topics, such as Tiananmen Square, is affected by censorship, raising concerns among users about its open-source status and censorship mechanisms.
Users have observed that QvQ has a verbose and casual style, and while it can manage some tasks like math equations, it often fails with more complex challenges.
The investigation of EgyptAir Flight 804's crash reveals discrepancies between the French BEA (Bureau of Enquiry and Analysis for Civil Aviation Safety) and the Egyptian EAAID (Egyptian Aircraft Accident Investigation Directorate) reports.
Key issues discussed include cockpit smoking regulations, the use of pure oxygen in aviation, and the difficulty of unbiased investigations in authoritarian regimes.
The debate centers on the Egyptian authorities' focus on a bomb theory, despite contrary evidence, highlighting the impact of political influence on safety culture and accident investigations.
A new lightweight, privacy-focused web browser is being developed, which uniquely operates without JavaScript, using updated scripts to enhance websites instead.- The browser employs a whitelist strategy to block resources from various domains, effectively avoiding trackers and enhancing user privacy.- The developer is running a fundraiser to support the advancement of this project, inviting contributions from interested parties.
FixBrowser is a lightweight, privacy-focused web browser that enhances privacy by blocking resources from different domains using a whitelist approach.
It is developed in FixScript, a secure and portable language, and does not support JavaScript, though there is potential for integrating other scripting engines.
The project is open-source and seeks funding for further development, aiming to support multiple platforms, including Linux and MacOS.
A graduate student with ADHD developed a website to assist with systematic literature reviews by finding similar papers based on meaning.- The site utilizes MixedBread's embedding model for vector representation, Milvus for storage and search, and Gradio for serving the application.- The vector database is updated weekly using Kaggle data, and search efficiency is enhanced by binarizing embeddings and employing Hamming distance.
A new website has been developed for semantically searching ArXiv papers using MixedBread's embedding model, Milvus for vector storage, and Gradio for the frontend.
The database is updated weekly from Kaggle, and Hamming distance is used for faster searches, with user feedback suggesting additional features and broader applications.
Discussions include potential uses of semantic search in marketing and e-commerce, as well as technical aspects like embedding models and reranking strategies.
Mark Rejhon, in collaboration with Timothy Lottes, has introduced a new open-source algorithm for simulating CRT (Cathode Ray Tube) displays, available on Shadertoy and GitHub.- This algorithm reduces motion blur on 240Hz+ displays and offers a softer flicker compared to BFI (Black Frame Insertion), and has been integrated into the Retroarch emulator.- The simulation is compatible with LCDs and OLEDs, providing real-time and slow-motion modes, and is particularly effective for reducing motion blur in legacy 60fps content.
The discussion centers on CRT (Cathode Ray Tube) simulation in GPU shaders, which some users find superior to black frame insertion for emulating old video game visuals.- Users report issues such as persistent banding, flickering, and color shifting, indicating challenges in achieving a convincing CRT effect on modern displays.- Achieving a realistic simulation may require high refresh rates, potentially up to 1000Hz, to reduce motion blur, though this can introduce flickering and artifacts.
