Concise monthly summary for 2025-10 focusing on key accomplishments in keras-team/keras-io. Highlights include implementing a fixed survey banner on the Keras landing page to collect user feedback, followed by removal of the banner and update of keras_hub dependency to declutter and stabilize the landing page. No major bugs fixed this month; however, UX polish and dependency hygiene delivered business value by improving user feedback capture and page stability. Key measurements are reflected in improved landing page usability and reduced maintenance overhead.

Delivered the vault_gemma_1b_en preset to the Gemma presets in keras-team/keras-hub, enabling recognition and use of this Gemma model variant within the Keras Hub framework. This improves model catalog completeness, discoverability, and onboarding for Gemma 1B EN deployments. Linked to bug fix Fixes (#2395) for traceability and reproducibility.

August 2025 monthly summary: Delivered key features and stability improvements across multiple backends, with measurable impact on scalability and numerical robustness. Highlights include cross-backend Cholesky inverse (with upper-triangular support) implemented across Keras backends and accompanied by comprehensive tests, and a JAXTrainer refactor using jax.jit out_shardings for improved distributed state sharding, plus removal of deprecated state-enforcement patterns. A bug fix improved numerical stability in DisentangledSelfAttention positional embeddings by enforcing proper dtype handling. These efforts collectively broaden backend compatibility, strengthen distributed training workflows, and reduce numerical errors in production workloads, delivering business value through more reliable model training and deployment.
