Research Papers
View allAre We Ready for RL in Text-to-3D Generation? A Progressive Investigation
This paper is a systematic exploration of reinforcement learning for text-to-3D generation, dissecting reward design, RL algorithms, data scaling, and hierarchical optimization. The authors introduce a new benchmark (MME-3DR), propose Hi-GRPO for global-to-local 3D refinement, and build AR3D-R1—the first RL-tuned text-to-3D model that improves both global shape quality and fine-grained texture alignment.
OPV: Outcome-based Process Verifier for Efficient Long Chain-of-Thought Verification
OPV (Outcome-based Process Verifier) is a verifier model that inspects the rationale steps of long chains-of-thought via summarized outcomes, combining the strengths of outcome-based and process-based verification. Trained with an active learning loop, rejection fine-tuning, and RLVR, OPV reaches strong F1 on OPV-Bench and outperforms much larger models like Qwen3-Max-Preview at detecting reasoning errors.
Long-horizon Reasoning Agent for Olympiad-Level Mathematical Problem Solving
This work presents a long-horizon reasoning agent for Olympiad-level math that uses an Outcome-based Process Verifier (OPV) to supervise and clean up very long chains-of-thought. By summarizing and checking reasoning segments rather than only final answers, and training OPV via iterative active learning and RLVR, the system achieves new SOTA on a held-out benchmark while reducing annotation cost.
T-pro 2.0: An Efficient Russian Hybrid-Reasoning Model and Playground
T-pro 2.0 is an open-weight Russian large language model focused on hybrid reasoning: it can answer directly or emit explicit reasoning traces, and it’s optimized for low-latency inference via speculative decoding. Alongside the model, the authors release a Russian instruction corpus, a math benchmark, and an EAGLE-based inference stack, making it a practical foundation for Russian-language reasoning applications.
DeepSeek-V4.1-Flash: Pushing the Limits of KV Cache Compression
DeepSeek-V4.1-Flash is a 552B-parameter MoE model tuned for million-token contexts with extremely compressed KV caches. It slashes memory and bandwidth while staying strong on text and image-heavy agent workloads.
AREX: Towards a Recursively Self-Improving Agent for Deep Research
AREX is a research agent that repeatedly checks its own partial answers, then uses those checks to drive new searches and reasoning steps. It trains specialized models and reward signals so the agent can handle very long tasks and beat similar sized systems on deep research benchmarks.
Trending Repositories
View allstable-diffusion-webui
stable-diffusion-webui by AUTOMATIC1111 is the de facto standard local web interface for Stable Diffusion, providing a massive feature set—txt2img, img2img, inpainting/outpainting, upscaling, LoRA/embeddings support, training utilities, and a huge extension ecosystem—on top of consumer GPUs. If you’re doing any kind of image generation or fine-tuning with Stable Diffusion in a local or lab environment, this is usually the first tool people reach for and the one most community workflows target.

opendatalab/MinerU
Pipeline that converts messy PDFs and Office docs into clean markdown or JSON tuned for LLM and agent workflows. It's quickly becoming a standard pre-processing tool. Plug it in if you're serious about document-heavy RAG. ([github.com](https://github.com/trending?since=daily))
ggml-org/llama.cpp
llama.cpp keeps pushing local LLM performance on CPUs and small GPUs. It’s still the reference for running big models on modest hardware. If you care about running the AI cheaply or on-device, you should track every major change here.
obra/superpowers
Superpowers is a skills library and workflow for coding agents like Claude Code and OpenCode. It bakes in design, planning, testing, and review loops so agents behave like disciplined junior engineers.
alibaba/open-code-review
CLI tool that runs a disciplined AI code review pipeline on your diffs. It combines hard-coded checks with an LLM agent to give precise, line-level feedback.
huggingface/transformers
Transformers is the go to Python library for running and customizing modern language, vision, and audio models. It wraps dozens of model families with a common API and production ready utilities. If you prototype or ship LLMs, this is still the main entry point.

View allSynthID Detector: Identify content made with Google's AI tools
Google announces SynthID Detector, a web portal that lets you upload images, audio, video, or text generated with Google AI tools and automatically checks for imperceptible SynthID watermarks, highlighting which parts of the content are likely watermarked. For developers and media teams, it’s a turnkey authenticity check for content produced with models like Gemini, Imagen, Lyria, and Veo, designed to plug into editorial and trust-&-safety workflows.

A model guide for the GPT‑6 family
OpenAI lays out concrete playbooks for picking GPT 6 variants, controlling effort, and keeping costs in check. If you build on GPT 6, this is basically the operator’s manual you should copy into your internal runbooks.
