xAI 为 Grok 推出代号 Aurora 的自回归图像生成模型
Grok Image Generation Release We are updating Grok's capabilities with a new autoregressive image generation model, code-named Aurora, available on the 𝕏 platform. Dec 9, 2024
xAI 为 Grok 上线新图像生成模型，代号 Aurora，已在 𝕏 平台部分国家可用，一周内推向全部用户。Aurora 是自回归 MoE 网络，基于交错文本和图像数据预测下一个 token，训练数据来自互联网数十亿样本，擅长照片级渲染和精确遵循文本指令，并原生支持多模态输入，可用用户图片作灵感或直接编辑，图像编辑功能即将开放。
xAI 官方说明了 Aurora 的架构与训练方式，并附与 Imagen 3、Flux.1 Pro 等模型的同题对比图，可据此了解其图像生成定位。
A newer model is available
Grok Imagine API is here
Our most powerful generative model yet — state-of-the-art video generation, video editing, and image creation, all in one API.
We've enhanced Grok's image generation abilities with a new model, code-named Aurora. Aurora is an autoregressive mixture-of-experts network trained to predict the next token from interleaved text and image data. We trained the model on billions of examples from the internet, giving it a deep understanding of the world. As a result, it excels at photorealistic rendering and precisely following text instructions. Beyond text, the model also has native support for multimodal input, allowing it to take inspiration from or directly edit user-provided images.
Grok's new capabilities are now available on the 𝕏 platform in select countries and will roll out to all users within a week.
Image Generation
Grok can now generate high-quality images across several domains where other image generation models often struggle. It can render precise visual details of real-world entities, text, logos, and can create realistic portraits of humans.
