Google is building a chip with Gemini baked into the silicon

TNW 2 months ago 14 ● 19 sources

Google is reportedly developing a chip called Frozen v2 that would have Gemini's neural-network architecture physically etched into the silicon rather than stored in memory, potentially achieving 6 to 10 times greater efficiency than current custom AI chips and targeting deployment as early as 2028. The project reflects Google's effort to reduce reliance on Nvidia and address internal capacity constraints, trading flexibility for speed and power efficiency. If successful, this approach could force competitors to develop similar custom silicon solutions optimized for specific models rather than general-purpose hardware.

Accelerating Text-to-Video Generation with Calibrated Sparse Attention

Apple 2 months ago 50

Researchers introduced CalibAtt, a training-free method that speeds up text-to-video generation by identifying and skipping unnecessary attention computations in transformer models. The technique achieves up to 1.58× end-to-end speedup on models like Wan 2.1 14B and Mochi 1 by using offline calibration to detect sparse attention patterns that remain stable across different inputs. This acceleration allows video diffusion models to generate content faster without degrading quality or text-video alignment.
