AWS Nova Forge could be your company's cue to start building custom AI models (www.techradar.com)

AWS has launched Nova Forge, a new service at re:Invent 2025 that enables businesses to customize AI models tailored to their specific needs. Users can select a starter model alongside curated Amazon datasets, facilitating the creation of custom "Novellas"—versions of AWS AI models that can be pre-trained, mid-trained, or post-trained. This approach significantly reduces the cost and time involved in developing custom AI solutions, which traditionally required millions of dollars and extensive labor. The introduction of Nova Forge, paired with the announcement of Nova 2 featuring four foundational models, marks a significant advancement for companies seeking to leverage AI without starting from scratch. These foundational models are available in tiers that cater to varying workloads, including new capabilities for humanlike speech-to-speech interactions. Importantly, AWS CEO Matt Garman highlighted the challenges in model adaptation, likening the model training process to language learning, emphasizing the importance of tailored training data without losing core reasoning capabilities. This development positions AWS as a key player in the democratization of AI model customization, making advanced tools more accessible to a broader range of enterprises.
