# `InstructorLite.JSONSchema`
[🔗](https://github.com/martosaur/instructor_lite/blob/v1.3.0/lib/instructor_lite/json_schema.ex#L1)

Helper module to generate JSON Schema based on Ecto schema.

JSON Schema comes in many flavors and different LLMs have different limitations. Currently, this module aims to implement a schema suitable for [OpenAI structured outputs](https://platform.openai.com/docs/guides/structured-outputs/supported-schemas). This type of JSON schema may not be optimal or compatible with other models. Therefore, it's recommended to use this module as a starting point to generate a schema during development. You can then manually refine the schema and either implement it in the `c:InstructorLite.Instruction.json_schema/0` callback or pass it as an option.

> #### Warning {: .warning}

> For the reasons described above, neither backward compatibility nor compatibility with all built-in adapters are goals of this module.
