🎯 Real-World Use Cases

Runtime code improvement

Let the model adjust code based on how it actually executes rather than only how it reads.

Hardware adaptation

Retarget the same routine to different hardware while keeping equivalence proofs.

Proof-backed refactors

Get an equivalence proof with each change instead of trusting a benchmark delta.

⚖️ Honest Review

✅ Pros

+Equivalence is formally proven, not just tested
+Adapts to real hardware and data
+Targets a layer most code tools ignore

⚠️ Cons

−Early access only at launch
−Claims are vendor-stated and not yet independently benchmarked
