Cline benchmark

An open source agent inside your editor that asks permission before each step, which is slower to drive and much easier to trust. It matched the commercial agents on the correctness prompts and lost time to the approval loop rather than to the model. Cost per full run was among the lowest we recorded because nothing is spent on a platform licence.

What agent performance looked like in practice

An open source agent inside your editor that asks permission before each step, which is slower to drive and much easier to trust. It matched the commercial agents on the correctness prompts and lost time to the approval loop rather than to the model. Cost per full run was among the lowest we recorded because nothing is spent on a platform licence.

Across 45 recorded executions this product met the published pass criterion cleanly 36 times, partially 8 times and failed 1 times. The rows above carry the reviewer note for every non clean outcome, which is the only way to tell a product that fails loudly from one that fails quietly.
