Re:We made Playwright 2x faster and 80% more token efficient by MiguelG719 on Saturday September 19, 2026 @01:31PM (#49768496)
We also just added Jev support https://github.com/browserbase/stagehand/pull/2952

On the act/extract/observe evals it shows promising results being extremely efficient

- act: 4.3x faster, 97% fewer LLM calls. Pass rate: 97.5% -> 98.3%. - heldout: 4.1x faster, 78% fewer LLM calls. Pass rate: 87.5% -> 97.5%. - observe: 11.1x faster, 69% fewer LLM calls. Pass rate: 75.0% -> 83.3%. - extract: 8.7x faster, 75% fewer LLM calls. Pass rate unchanged at 92%.

cost effectively 0
