LLM-mock v1.0: Record and Replay OpenAI and Anthropic Calls in pytest

LLM-mock v1.0 is presented as an open-source testing tool for recording and replaying OpenAI and Anthropic API calls in pytest. The approach can make LLM integration tests more deterministic and reduce dependence on live providers, latency, and API spending. However, the supplied evidence is limited to a Hacker News submission and its GitHub link; the project’s exact APIs, cassette format, masking behavior, and provider coverage require verification in the repository.
