Google is slow but has the well-rounded talent and resources to progress. Google Voice is superior to US competitors for both English and Chinese. Gemini is free and doesn't require phone number registration, a big deal.



A even bigger hack on 4090 rumored:

Yes this is what the Ada rtx Quadro was supposed to be. VRAM in clamshell arrangment. There is a 50 series model with 96 GB in testing. What they have done is they have removed the GPU from the board and reassembled it on another board with more capacity. Nvidia has a lot of market segmentation so these exotic products are possible if one knows how to achieve it.

Tsinghua and RealAI jointly released RealSafe R1, a hardened and optimized version of DeepSeek R1. They added "security awareness" to the model in "post-training" to protect against malicious prompts. This hardened version scores better than Claude 3.5 and GPT-4o in security tests.

2月23日,清华大学与瑞莱智慧联合团队推出大语言模型RealSafe-R1。该模型基于DeepSeek R1进行深度优化与后训练,在确保性能稳定的基础上,实现了安全性的显著提升,表现优于被认为安全性较好的闭源大模型Claude3.5、GPT-4o等,为开源大模型安全发展与风险治理提供了创新性解决方案。

连日来,国产开源大模型DeepSeek的优异表现令人惊艳,其在自然语言处理和多任务推理方面的能力展现了强大的技术实力,尤其是在复杂问题解决和创造性任务中表现出色。然而,DeepSeek R1和V3在面对越狱攻击等安全性挑战时仍存在一定的局限性。例如,模型可能会被恶意设计的输入误导,生成不符合预期或不安全的响应。这一安全短板并非DeepSeek所独有的难题,而是当前开源大模型的通病,其根本缺陷源于安全对齐机制的深度不足。

为此,清华瑞莱联合团队提出了基于模型自我提升的安全对齐方式,将安全对齐与内省推理相结合,使大语言模型能够通过具有安全意识的思维链分析来检查潜在风险,实现基础模型自身能力的自主进化,可以应用于多种开源、闭源模型。

基于该方法,团队对DeepSeek-R1系列模型进行后训练,正式推出RealSafe-R1系列大模型。实验数据表明,RealSafe-R1安全性显著提升,在多个基准测试中有效增强了对各种越狱攻击的抵抗力,并减轻了安全与性能之间“跷跷板”现象,表现优于被认为安全性较好的闭源大模型Claude3.5、GPT-4o等,不仅为DeepSeek生态添砖加瓦,也为大语言模型树立了新的安全标杆。

据悉,RealSafe-R1各尺寸模型及数据集,将于近期向全球开发者开源。“大模型的安全性瓶颈是本质的,只有通过持续投入和攻坚补齐短板弱项,人工智能产业才能真正实现高质量发展。”瑞莱智慧首席执行官田天表示,这一创新成果将为开源大模型的安全性加固提供有力支持,也为政务、金融、医疗等严肃场景的应用提供更为可靠的坚实基座。
