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.
A Safety Report on GPT-5.2, Gemini 3 Pro, Qwen3-VL, Doubao 1.8, Grok 4.1 Fast, Nano Banana Pro, and Seedream 4.5
This report compares seven frontier language and vision models across many safety tests, from basic benchmarks to adversarial red-teaming. It finds GPT-5.2 clearly safest overall while others trade off safety across languages, modalities, and threat models.
HuggingFace's Transformers: State-of-the-art Natural Language Processing
This 2019 paper launched the Transformers library, giving a clean API around many transformer models and pretrained checkpoints. It turned cutting-edge NLP into a reusable software layer that underpins most open-source LLM work today.

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. ([github.com](https://github.com/AUTOMATIC1111/stable-diffusion-webui?utm_source=openai))
huggingface/transformers
The standard library for state-of-the-art models in text, vision, audio, and combined formats. If you build with open models, you almost certainly depend on this already.
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.
anomalyco/opencode
OpenCode is an open-source coding agent that edits and writes code for you, wired into modern tooling. Use it as a local, hackable alternative to proprietary AI dev environments.
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.
