Sam Witteveenhigh confidence
Why it matters
- →Voice cloning is now available via API with built-in safety guardrails.
- →Multi-speaker dialogue and stage directions enable complex audio storytelling.
- →Public Colab access allows immediate testing without enterprise onboarding.
Google has released Gemini 3.8 Flash TTS, a new text-to-speech model featuring voice cloning and multi-speaker dialogue capabilities. The model supports over 2,000 pre-designed voices and allows users to inject stage directions and non-verbal tags for expressive control. A public Colab notebook is available for testing the API, which includes guardrails for voice cloning safety. This release positions Google as a key player in accessible, high-quality generative audio.

llama.cpp b11193 adds Snapdragon Hexagon and ROCm 10
This release quietly expands llama.cpp's hardware support to include Qualcomm's Hexagon NPU on Linux arm64, a significant step for local inference on Snapdragon devices. It also updates CUDA builds to version 13.4 and introduces ROCm 10.0 binaries, keeping the project aligned with the latest NVIDIA and AMD driver ecosystems. KleidiAI on Apple Silicon is temporarily disabled in this build, likely due to stability checks rather than a feature rollback. For developers targeting edge AI or diverse GPU stacks, this update ensures broader compatibility without requiring custom compilation.
