The Rise of Affordable AI: NovaSky’s Sky-T1-32B-Preview
Imagine a world where cutting-edge AI models are not only accessible but also affordable. That’s exactly what NovaSky, a research team from UC Berkeley’s Sky Computing Lab, is making possible. They’ve introduced Sky-T1-32B-Preview, a reasoning AI model that competes with earlier versions of OpenAI’s models on several important benchmarks. What sets Sky-T1 apart is its open-source nature—it’s the first reasoning model that can be fully replicated using publicly available resources. The team even shared the dataset and training code they used. Amazingly, training this model cost less than $450, as they proudly announced in a blog post.
- Sky-T1’s training cost was remarkably low at under $450.
- This model can self-verify, reducing common AI errors.
- It takes a bit longer to reach conclusions but excels in reliability.
“Remarkably, Sky-T1-32B-Preview was trained for less than $450,” the team wrote, “demonstrating that it is possible to replicate high-level reasoning capabilities affordably and efficiently.”

Reasoning models like Sky-T1 have a unique advantage over typical AI—they can effectively fact-check themselves. This means fewer errors in domains like physics and mathematics, though they may take a few extra seconds to deliver results. To train Sky-T1, NovaSky utilized another reasoning model, Alibaba’s QwQ-32B-Preview, to create initial training data. They then refined this data with OpenAI’s GPT-4o-mini for better efficiency.
The training process took 19 hours using 8 Nvidia H100 GPUs to handle the model’s impressive 32 billion parameters—each representing part of its problem-solving prowess. Sky-T1 has already shown its mettle by outperforming an early version of OpenAI’s o1 on MATH500, a challenging math benchmark, and LiveCodeBench coding evaluations. However, it still lags behind o1 in GPQA-Diamond tests covering advanced scientific topics.
While OpenAI is expected to release an even more advanced model soon, NovaSky sees Sky-T1 as just the beginning of their journey towards developing open-source models with enhanced reasoning abilities. They are committed to creating efficient models that maintain strong performance while exploring new techniques to boost accuracy and efficiency.
“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 wrote in the post. “Stay tuned as we make progress on these exciting initiatives.”
