This is still an early-stage project — it's not completed yet, and fabricating a custom chip would involve huge costs.
I'm a solo developer worked on this in my spare time, so FPGA was the most practical way to prove the core concepts and validate the architecture.
Longer term, I definitely see ASIC fabrication as the way to unlock PyXL’s full potential — but only once the use case is clear and the design is a little more mature.
