Cline says Sonnet 5.5 beats Opus 5.5 on Terminal-Bench 4.0 at half the cost.

Cline also says the model uses far fewer tokens than previous models for the same work, with costs reduced by up to 30% per task. It generates output 30% faster than its predecessor, which Cline calls the fastest Sonnet model to date.
