Instead of validating and converting all fields when an object is created, it stores raw input data and only processes each field when you read it. This can reduce startup latency for objects with many fields or expensive validators that you may never use.\n\nThe library integrates directly with Pydantic's validator system, so custom validators run during lazy parsing just as they would in a standard Pydantic model. Fields are marked as unparsed (NAO\u2014Not An Object) until accessed, at which point type conversion and validation occur. It depends only on pydantic and supports Python 3.9 and later.","worth_installing":"Yes, if you work with Pydantic models and have a specific use case for deferred parsing (large objects, expensive validators, or partial field access patterns). The low install friction and permissive license make it a low-risk experiment. However, verify compatibility with your Pydantic version and measure whether lazy parsing actually improves your workload, since the aging maintenance status suggests limited ongoing development."},"id":"lazy-model","links":{"html":"https://skillfed.io/packages/lazy-model","md":"https://skillfed.io/packages/lazy-model.md","pypi":"https://pypi.org/project/lazy-model/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-08-07","license_spdx":null,"license_treatment":"permissive","name":"lazy-model","python_support":"supports_current","summary":null},"popularity":{"monthly_downloads":1703419,"position":3639,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.4.0"}
