SynthID Detector: Identify content made with Google's AI tools

Google AI BlogMay 20, 2025

Summary

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.

stable-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.

Are 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.
