According to Satya Nadella, Azure AI Foundry has introduced GPT-4.5, which is now in preview and showcases significant advancements in both pre-training and post-training scale. Additionally, new AI models from Cohere, Stability, and Microsoft have been unveiled, indicating a strategic push to integrate AI into product development. These updates could significantly impact AI-related stock movements and trading strategies as companies seek to leverage advanced AI capabilities.

According to @DeepLearningAI, researchers from Cohere have developed a method called active inheritance to optimize fine-tuning on synthetic data by selectively choosing training examples with desirable traits. This approach enhances model performance by reducing unwanted characteristics like toxicity, making it relevant for traders seeking reliable AI-generated insights.
