Stream-R1: Reliability-Perplexity Aware Reward Distillation for Streaming Video Generation
114 upvotes · Bin Wu et al. · Paper
A novel approach to improve distillation-based acceleration in streaming video generation by addressing two key problems: not all training examples are equally reliable, and not all pixels contribute equally to quality improvements. Stream-R1 uses a reward-guided mechanism to prioritize reliable training data and focus optimization on regions where refinement yields the largest gains. This addresses a fundamental limitation in current distribution matching distillation methods that treat all supervision signals equally, potentially unlocking better quality in practical streaming video applications.
Stream-T1: Test-Time Scaling for Streaming Video Generation
96 upvotes · Yijing Tu et al. · Paper
Introduces test-time scaling specifically tailored for streaming video generation, leveraging its chunk-level synthesis to make candidate exploration computationally feasible. The framework includes three key components: noise propagation that uses high-quality previous chunks to guide current generation, reward-based pruning that balances spatial and temporal quality, and memory management for KV-cache optimization. This represents a shift from expensive training-time scaling to more practical inference-time improvements, addressing the computational bottlenecks that have limited test-time scaling adoption in video generation.
RLDX-1 Technical Report
94 upvotes · Dongyoung Kim et al. · Paper
A general-purpose robotic policy for dexterous manipulation that significantly outperforms recent frontier VLAs like π_{0.5} and GR00T N1.6, achieving 86.8% success rates on ALLEX humanoid tasks versus ~40% for competitors. RLDX-1 addresses key limitations in current Vision-Language-Action models by integrating motion awareness, memory-aware decision making, and physical sensing through its Multi-Stream Action Transformer architecture. The performance gap suggests current VLAs may be hitting fundamental architectural limitations for complex manipulation tasks.
🛠 Tools
Hmbown/DeepSeek-TUI — Terminal coding agent for DeepSeek V4
5,799/day · Repo
A Rust-based terminal interface that brings DeepSeek V4's reasoning capabilities directly to your command line with streaming reasoning blocks and workspace editing with approval gates. The tool includes an auto mode that dynamically chooses both model and thinking level per turn, making it practical for real coding workflows. With 20,493 stars and multiple installation methods (npm, cargo, homebrew, docker), it represents the growing trend of bringing powerful language models into developer toolchains with proper safety controls.
addyosmani/agent-skills — Production-grade engineering skills for AI coding agents
3,062/day · Repo
A systematic approach to encoding senior engineering workflows into reusable skills that AI agents can follow consistently across development phases. The framework provides 7 slash commands mapping to the development lifecycle (/spec, /plan, /build, /test, /review, /code-simplify, /ship) with automatic skill activation based on context. With 33,578 stars, this addresses a critical gap in AI coding tools: moving beyond code generation to implementing the quality gates and best practices that experienced developers use.

llm-gemini 0.31
May 7th · Post · tags: llm-release, gemini, llm, google, generative-ai, ai, llms
Google's Gemini 3.1 Flash-Lite has graduated from preview to general availability without apparent changes since the March preview. Simon notes this as a straightforward release update for his LLM plugin ecosystem. The lack of fanfare suggests Google is treating this as a routine productization step rather than a major capability update.
Behind the Scenes Hardening Firefox with Claude Mythos Preview
May 7th · Post · tags: firefox, mozilla, security, ai, generative-ai, llms, anthropic, claude, ai-security-research
Mozilla used Claude Mythos preview access to dramatically scale their security bug discovery, jumping from 20-30 monthly fixes to 423 in April alone. The key insight is that AI-generated security reports have evolved from "unwanted slop" to genuinely valuable findings through better models and improved techniques for steering and filtering. Mozilla found bugs dating back 15-20 years, though many attempts were blocked by existing defense-in-depth measures, validating their security architecture.
