How alternatives are selected

Alternatives must have a benchmark score and the same current open/closed classification as the target. They are sorted by score distance, then by price/performance. The table compares hosted API economics; it does not establish licence compatibility or self-hosting rights.

Check the model licence, provider Terms, context limits, tool support, and output quality before switching a production workload.
