NovaSky’s Sky-T1-32B-Preview: A Game-Changer in Affordable AI Reasoning Models
In a groundbreaking move, novasky, a team of researchers from UC Berkeley’s Sky Computing Lab, has unveiled the Sky-T1-32B-Preview, a fully open-source reasoning model that rivals openai’s earlier o1-preview on key benchmarks. What makes this release truly remarkable? The model was developed for less than $450, a fraction of the cost typically associated with high-performance AI systems.
“Remarkably, Sky-T1-32B-Preview was trained for less than $450,” the team wrote in a blog post, “demonstrating that it is indeed possible to replicate high-level reasoning capabilities affordably and efficiently.”
This achievement marks a meaningful milestone in the democratization of AI development. Just a few years ago, training models with comparable performance frequently enough required budgets in the millions of dollars. The use of synthetic training data, generated by other AI models, has been a key driver in reducing costs. As an example, Writer’s Palmyra X 004, trained almost entirely on synthetic data, reportedly cost $700,000 to develop.

Unlike conventional AI models, reasoning models like Sky-T1 are designed to fact-check themselves, minimizing errors that typically plague other systems. While they may take slightly longer to arrive at solutions—frequently enough seconds to minutes more—they excel in reliability, especially in fields like physics, science, and mathematics.
The NovaSky team leveraged Alibaba’s QwQ-32B-Preview to generate the initial training data for Sky-T1. They then curated the data mixture and used OpenAI’s GPT-4o-mini to refine it into a more workable format. Training the 32-billion-parameter model took approximately 19 hours using a rack of 8 Nvidia H100 gpus.
Performance Benchmarks
Sky-T1 has already demonstrated impressive capabilities. It outperforms the early preview version of OpenAI’s o1 on MATH500, a collection of competition-level math challenges, and excels in coding evaluations from LiveCodeBench.
However, it’s worth noting that OpenAI’s GA release of o1 is a more advanced model than its preview version, and the company is expected to launch an even more powerful reasoning model, o3, in the coming weeks.
The Road Ahead for NovaSky
For NovaSky, Sky-T1 is just the beginning. The team is committed to developing open-source models with advanced reasoning capabilities.
“Moving forward, we will focus on developing more efficient models that maintain strong reasoning performance and exploring advanced techniques that further enhance the models’ efficiency and accuracy at test time,” the team shared in their blog post.

Interview: NovaSky’s Sky-T1-32B-Preview and the Future of Affordable AI Reasoning models
In a groundbreaking advancement, NovaSky, a team of researchers from UC Berkeley’s Sky Computing Lab, has unveiled the Sky-T1-32B-preview, a fully open-source reasoning model that rivals OpenAI’s earlier o1-preview on key benchmarks. What makes this release truly remarkable is its affordability—developed for less than $450. To delve deeper into this innovation, we sat down with Dr. Emily Carter, a leading AI researcher and expert in reasoning models, to discuss the implications of this breakthrough and what it means for the future of AI development.
The Breakthrough: Affordable High-Performance AI
senior Editor: Dr. Carter, the Sky-T1-32B-Preview was developed for less than $450, which is a fraction of the cost typically associated with high-performance AI systems. How critically important is this achievement in the broader context of AI development?
Dr. Carter: This is a monumental achievement. Just a few years ago, training models with comparable performance required budgets in the millions of dollars. The fact that NovaSky has managed to develop a model like Sky-T1 for under $450 is a testament to the power of innovation and the effective use of synthetic training data. It democratizes AI development, making high-performance models accessible to a much wider range of researchers and organizations.
What Sets Sky-T1 Apart?
Senior Editor: Unlike conventional AI models, reasoning models like Sky-T1 are designed to fact-check themselves. can you explain how this works and why it’s vital?
Dr. Carter: Traditional AI models often struggle with reliability, especially in complex fields like physics, science, and mathematics. Reasoning models like Sky-T1 are designed to minimize errors by fact-checking their own outputs. While this might take a bit longer—sometimes seconds to minutes more—the trade-off is significantly higher reliability. This is crucial for applications where accuracy is paramount, such as scientific research or advanced problem-solving.
Training and Development
Senior editor: The NovaSky team leveraged Alibaba’s QwQ-32B-Preview to generate initial training data and used OpenAI’s GPT-4o-mini to refine it. Can you walk us through the training process and why these tools were chosen?
Dr.Carter: The training process for Sky-T1 was remarkably efficient. The team used Alibaba’s QwQ-32B-Preview to generate the initial data,which was then curated and refined using OpenAI’s GPT-4o-mini. This combination allowed them to create a high-quality dataset without the exorbitant costs typically associated with data collection. The entire training process took just 19 hours using a rack of 8 Nvidia H100 GPUs, which is incredibly fast for a model of this size and complexity.
Performance Benchmarks
Senior Editor: Sky-T1 has already demonstrated impressive capabilities, outperforming OpenAI’s o1-preview on MATH500 and LiveCodeBench. How do these benchmarks reflect the model’s potential?
Dr. Carter: These benchmarks are a strong indicator of Sky-T1’s capabilities. MATH500, in particular, is a collection of competition-level math challenges, and excelling in this area shows that the model has robust reasoning abilities.Similarly, performing well on LiveCodeBench indicates that Sky-T1 is not just a theoretical model but has practical applications in coding and problem-solving. While OpenAI’s GA release of o1 is more advanced,Sky-T1’s performance is incredibly promising,especially given its low development cost.
The Road Ahead for NovaSky
Senior Editor: NovaSky has stated that Sky-T1 is just the beginning. What do you think the future holds for open-source models with advanced reasoning capabilities?
Dr. Carter: The future is incredibly bright. NovaSky’s commitment to open-source models is a game-changer. by focusing on developing more efficient models that maintain strong reasoning performance, they are paving the way for a new era of AI development.
