AMD has announced details of its upcoming Instinct MI355X AI accelerator, which is expected to be released in the second half of 2025. The chip is based on the new CDNA4 architecture and will be manufactured by TSMC using the 3-nanometer process. With up to 288GB of HBM3E memory and a performance of 2.3 petaflops at FP16 and 4.6 petaflops at FP8, it will be significantly more powerful than its predecessor, the MI300X. AMD is also introducing new data formats such as FP4 and FP6, which are expected to deliver up to 9.2 petaflops. AMD is aiming for similar performance to Nvidia's upcoming Blackwell B200. At the same time, AMD announced the official start of production of the MI325X, albeit with a reduced memory of 256 GB instead of the originally announced 288 GB.

Google is rolling out its latest image generation AI, Imagen 3, to all Gemini users worldwide, including free accounts. The company claims that Imagen 3 is its most powerful image model yet, outperforming competitors such as DALL-E 3, Midjourney v6, and Stable Diffusion 3 in internal testing. Imagen 3 is said to excel at following detailed text prompts and producing highly photorealistic images. Google says the model produces fewer distracting artifacts than previous versions, but still struggles with tasks that require numerical or spatial reasoning, as well as complex language prompts. To combat potential misuse, Google has implemented safety filters and digital watermarking. Google took down an earlier version because people were using it to generate Black people in Nazi uniforms.
