◆ ◆ The Wire takeaway
If you're building AI applications on proprietary models, you now have a fully open alternative that costs less to run and matches paid competitors on benchmarks. The efficiency win—activating only 10% of parameters—means you can deploy at scale on cheaper hardware, which changes your unit economics.
