This is exciting stuff!

My interpretation:
If the JSIR project can successfully prove bi-directional source to MLIR transformation, it could lead to a new crop of source to source compilers across different languages (as long as they can be lowered to MLIR and back).

Imagine transmorphing Rust to Swift and back. Of course you’d still need to implement or shim any libraries used in the source language. This might help a little bit with C++ to Rust conversions - as more optimizations and analysis would now be possible at the MLIR level. Though I won’t expect unsafe code to magically become safe without some manual intervention.

The title is misleading. It should be read as “Some $20/month users who made videos on Sora costed OpenAI $65 in compute.”

OpenAI is most definitely in a position to be profitable. They are spending less than a third of their revenue on compute (all infrastructure costs combined).
