Unlike the former, Playground is stateless and forgets nothing, even removing features such as saved prompts, version history, evals, and team sharing. Anthropic allows users until September 1 to export their old Workbench data. OpenAI's Playground, meanwhile, has been around since 2020, and the company announced it would shut down saved prompts and evals on November 30.\n\nBoth companies concluded that prompts belong in code, not a web console. The author tested the new Playground against OpenAI's long-standing Playground by building a PR review bot. Anthropic's Playground successfully executed the test, creating Python code that ran on the author's laptop without any edits.

Anthropic's Playground proved more efficient and reliable, checking a box in the company's \"always be launching\" goals.",
