Gemini Ultra is out, to mixed reviews

**Google** released **Gemini Ultra** as a paid tier for "Gemini Advanced with Ultra 1.0" following the discontinuation of Bard. Reviews noted it is "slightly faster/better than ChatGPT" but with reasoning gaps. The **Steam Deck** was highlighted as a surprising AI workstation capable of running models like Solar 10.7B. Discussions in AI communities covered topics such as multi-GPU support for OSS Unsloth, training data contamination from OpenAI outputs, ethical concerns over model merging, and new alignment techniques like Listwise Preference Optimization (LiPO). The **Mojo** programming language was praised for high-performance computing. In research, the **Subformer** model uses sandwich-style parameter sharing and SAFE for efficiency, and **BiLLM** introduced 1-bit post-training quantization to reduce resource use. The **OpenHermes** dataset viewer tool was launched, and GPU scheduling with Slurm was discussed. Fine-tuning challenges for models like **OpenHermes-2.5-Mistral-7B** and VRAM requirements were also topics of interest.
