l1m A Proxy to extract structured data from text and images using LLMs.

l1m (pronounced "el-one-em") serves as an intermediary API designed to streamline the extraction of structured data from unstructured text and images through the use of Large Language Models (LLMs). Its primary advantage lies in simplifying this process by eliminating the need for complex prompt engineering or managing chat histories. Users interact with a straightforward API, providing their unstructured input (text or image) alongside a JSON schema that defines the desired output structure.

The tool emphasizes ease of use and flexibility. It operates on a schema-first approach, ensuring the output precisely matches the user-defined JSON schema. l1m supports various LLM providers, including any OpenAI compatible or Anthropic provider, allowing users to integrate their preferred models. It also offers built-in caching capabilities controlled via headers and is available both as an open-source solution and a managed hosted version, ensuring no vendor lock-in and catering to different deployment needs. Data privacy is considered, as the service does not retain user data unless caching is explicitly activated.
