Using soft-verified generation and synthetic data, it can be reproduced for ~$400 or customized to private codebases for ~$1,300. The 32B parameter model matches or exceeds 100B+ parameter teachers on specific repositories, runs efficiently on NVIDIA hardware (up to 8,600 tokens/sec on Blackwell), and includes full training recipes, models, and data for complete reproducibility. ## Full article daily.dev links to this article rather than hosting it.
