Amazon Bedrock now enables reinforcement fine-tuning (RFT) across multiple model families including Amazon Nova, open-weight models like OpenAI's GPT-OSS 20B, and Qwen 3 32B. The service automates the end-to-end customization workflow using GRPO optimization, allowing models to learn from feedback on multiple responses rather than static training datasets, with support for OpenAI-compatible APIs.

Hume AI has released TADA-1B, a 1 billion parameter text-to-speech model available on Hugging Face under an MIT license. The model, which combines speech and language capabilities, has already accumulated over 3,100 downloads since its January 12 release.
