ClaudeAI Assistants & SearchClaude is an AI assistant launched by Anthropic that can assist with writing, reading materials, analyzing data, and programming through conversation, and can organize some tasks into editable documents, spreadsheets, or presentation files. It’s ideal for individuals and teams who want to connect their ideas, materials, and drafts.
GGeminiAI Assistants & SearchGemini is Google’s AI assistant, which can assist with writing, planning, organizing information, and analyzing uploaded files through conversation. It can also use Deep Research to retrieve information on a topic and generate research reports.
MMidjourneyImage Generation & EditingMidjourney is an AI-powered creative tool that generates visual artworks from text and reference images. On the web-based Create page, you can enter prompts, compare generated versions, and then continue creating using features such as variations, editing, upscaling, or converting images to video.
KKreaImage Generation & EditingKrea is an AI visual creation workspace that can generate images from text or reference images, compare different models and variants, and then perform editing, detail enhancement, and upscaling. It also provides access to video and other creative tools.
RRunwayVideo & AnimationRunway is an AI platform that integrates video generation, visual editing, and creative workflows. Starting from text, images, or existing clips, users can generate or modify shots, then extend, upscale, and export them—serving concept shorts, advertisements, and other visual productions.
SSunoMusic & AudioSuno is an AI music platform that creates songs from text descriptions, lyrics, and reference materials. Users can generate vocal tracks or instrumental music, then use features like editing, remixing, and audio track separation to further produce and share their creations.
EElevenLabsSpeech & TranscriptionElevenLabs is a platform that offers AI-powered voice generation, audio creation, and voice-enabled agents. Creators can produce voiceovers, audiobooks, podcasts, and localized content, while developers can leverage its APIs to integrate speech synthesis, transcription, and conversational capabilities.
NNotion AIOffice & ProductivityNotion AI is an AI assistant integrated into Notion workspaces, designed to search team knowledge, generate and edit pages, manage databases, and organize meeting notes. By leveraging the context of your workspace and connected apps, it helps you complete information retrieval, content organization, and follow-up tasks all within the same working environment.
GGammaOffice & ProductivityGamma is an AI-powered tool for creating presentations, documents, web pages, and visual content. It can generate content starting from a goal, an outline, or existing materials, and then refine the final output through conversational prompts, layout adjustments, and free-form editing.
CCursorCoding & DevelopmentCursor is an AI programming product designed to support software development tasks, assisting with code planning, modification, testing, and review within the code context, and offering usage options such as desktop, command-line, and cloud-based agents.

RL without TD learning
In this post, I’ll introduce a reinforcement learning (RL) algorithm based on an “alternative” paradigm: divide and conquer. Unlike traditional methods, this algorithm is not based on temporal difference (TD) learning (which has scalability challenges), and scales well to long-horizon tasks. We can do Reinforcement Learning (RL) based on divide and conquer, instead of temporal difference (TD) learning. Problem setting: off-policy RL Our problem setting is off-policy RL. Let’s briefly review what this means. There are two classes of algorithms in RL: on-policy RL and off-policy RL. On-policy RL means we can only use fresh data collected by the current policy. In other words, we have to throw away old data each time we update the policy. Algorithms like PPO and GRPO (and policy gradient meth

What exactly does word2vec learn?
What exactly does word2vec learn, and how? Answering this question amounts to understanding representation learning in a minimal yet interesting language modeling task. Despite the fact that word2vec is a well-known precursor to modern language models, for many years, researchers lacked a quantitative and predictive theory describing its learning process. In our new paper, we finally provide such a theory. We prove that there are realistic, practical regimes in which the learning problem reduces to unweighted least-squares matrix factorization. We solve the gradient flow dynamics in closed form; the final learned representations are simply given by PCA. Learning dynamics of word2vec. When trained from small initialization, word2vec learns in discrete, sequential steps. Left: rank-increment
