Fast, accessible coding agents that adapt to any repo
SERA is a family of open coding models (8B, 14B, 32B) trained with a new efficient method. SERA learns from "soft-verified" data, drastically reducing training costs. Easily adaptable to private codebases. Open weights, data & recipes.
SERA (Soft-verified Efficient Repository Agents) is the latest from Ai2's Open Coding Agents project. They just updated it with a new 14B model and refreshed datasets.
Two technical points make this approach interesting:
First, SERA proves that models can learn effectively from "partially correct" patches—much like humans learning through debugging. This insight pushes synthetic data costs down significantly, with entry-level reproduction costing just ~$400.
Second, for teams with private codebases or specific internal frameworks, this is a solid option. You can specialize these models to your own stack efficiently.
Since they released everything (weights, data, recipe), it is a great resource if you want to build custom agents!

Who hunted SERA?
SERA was hunted by Zac Zuo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
