The Big Story
A groundbreaking development in artificial intelligence (AI) has sent shockwaves throughout the tech community, with Nace AI open-sourcing Drex 1.5, a 9B decision model that returns a probability for every option in one forward pass.
This monumental breakthrough has significant implications for the field of AI, particularly with regards to decision-making. Drex 1.5's ability to score options rather than text marks a major shift in the way AI models approach decision-making processes.
The model's impressive capabilities have been demonstrated through its ability to achieve a Decision Index 0.3.1 score of 58.08, reading up to 128K tokens in a single pass. This level of precision and efficiency is unprecedented in the field of AI, making Drex 1.5 an invaluable tool for researchers and developers.
As the tech community continues to grapple with the implications of this breakthrough, one thing is certain: Nace AI's decision to open-source Drex 1.5 will have a profound impact on the development of AI technology in the years to come.
What Shipped
Nace AI's Drex 1.5 has been open-sourced, a 9B decision model that returns a probability for every option in one forward pass. It scores 58.08 on Decision Index 0.3.1 and reads up to 128K tokens.
Microsoft has released Microsoft-Decision-1, a decision-scoring model that returns a calibrated probability for each possible outcome. This tool can be used for routing, classification, verification, and agent control.
Alibaba's Qwen team has released Qwen-Image-2.1-Turbo, an accelerated checkpoint of its open-weight Qwen-Image-2.1 model. This new image model generates and edits images in 8 denoising steps instead of the base model's multiple iterations.
OpenAI's Decisions API is now in public beta on GPT-6 Luna. It returns typed probabilities, choices, and scores about 10x faster than the Responses API, billing $0.10 per 1M input tokens with no output limits.
TypeSafe has released Jev, a non-text AI model that works significantly faster and uses far fewer tokens than LLMs. This new model has users and large corporations excited about its potential applications.
