HOW THIS AFFECTS YOU
●
builderA 5B active parameter model hitting 51% SWE-Bench Pro suggests you may soon get near-frontier coding performance at significantly lower inference cost inside Copilot.
●
researcher51% SWE-Bench Pro at 5B active params is a notable efficiency result that warrants scrutiny of the benchmark methodology and training data overlap.
