I was working (with agents) on testing out various attention algorithm ideas I had, and I found that the existing infrastructure/libraries made it more difficult than it should be. So I created Jacq, a DSL and compiler. A jacq file describes a model’s configuration, weights, layers, and pipeline. Jacq turns it into a standalone CUDA inference runtime and a Python weight exporter. Kernel descriptions can also generate CUDA harnesses. The easiest way to try it is the TinyLlama example in the…

From the discussion

A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.

@fiveapi_dev (not sure why you are flagged/dead, your question seems totally fine)...my main motivation was shortening the experiment loop. I wanted the DSL to be the thing my agent or myself edited, then regenerate the CUDA and throw the generated code away. Jacq also handles some of the repetitive setup stuff:…
