How these models were selected
The shortlist favors downloadable weights with credible public releases, practical serving options, and performance strong enough for production evaluation.
When to use a different shortlist
Open weights provide control, not free inference. Hardware, quantization, security updates, and operational staffing can outweigh API savings.
