We are working on making our programming language BAML turing-complete. https://github.com/boundaryml/baml It is a language that is embeddable in other programming languages, with the type system similar to typescript, and a runtime that…

You may also want to check out BAML https://github.com/BoundaryML/baml - a DSL for prompt templates that are literally treated like functions. the prompt.yaml format (which this project uses) suffers from the fact that it doesn't address…

Have you tried BAML? https://github.com/BoundaryML/baml

We're making a prompting DSL (BAML https://github.com/BoundaryML/baml ) and what we've found is that all the syntax rules can easily be encoded into a Cursor Rules file, which we find LLMs can follow nicely. DSLs are simple by nature so…

I've been using using [BAML]( https://github.com/boundaryml/baml ) to do this, and it works really well. Lets you have multiple different fallback and retry policies, and returns strongly typed outputs from LLMs.

comment by joatmon-snoo · 2025-02-20 · in Run structured extraction on documents/images locally with Ollama and Pydantic -
For structured output from anywhere I'm finding https://github.com/BoundaryML/baml good. It's more accurate than gpt-04-mini will do on its own, and any of the other JSON schema approaches I've tried.

Have you tried BAML ( https://github.com/boundaryml/baml )? It's really good at structured output parsing. We integrated it directly into our pipeline builder.
