FLUX.2 is the text-to-image model family from Black Forest Labs. It spans the proprietary Pro and Flex variants plus the open 32-billion-parameter Dev model and the compact Klein series, unifying image generation and image editing in a single model.
Microsoft TRELLIS.2 is the strongest open image-to-3D model (4B parameters, MIT license). It generates high-resolution assets with native PBR materials in seconds and supports Gaussian Splatting; weights are freely available on Hugging Face.
Chatterbox is an open-source text-to-speech model from Resemble AI under the MIT license. In blind tests most listeners preferred it over ElevenLabs; it offers emotion control, voice cloning and low latency.

Hunyuan3D 2.0 is Tencents open generative 3D model (January 2025). In two stages it produces high-resolution, textured 3D assets from text or image and supports text-, image-, sketch- and portrait-to-3D. The weights are freely available on Hugging Face.
Kokoro is an open text-to-speech model (v1.0, January 2025) with just 82M parameters. It produces natural-sounding speech in 8 languages with 54 voices, runs on around 1 GB of VRAM and ships under the Apache-2.0 license.
Canary is NVIDIAs open ASR and speech-translation model family (CC-BY-4.0) that tops the Open ASR Leaderboard on English accuracy ahead of OpenAI Whisper and covers 25 European languages.
SauerkrautLM is a German-language LLM family from the German startup VAGOsolutions — fine-tunes based on Llama, Qwen, Mistral, and other open architectures.
