LLM APIs are all different.

Open LLM Specification (OLLS) is an attempt to standardize request & response formats for GPT, Claude, Gemini, etc. → [GitHub Link]

Example:

Standardized input → prompt, params, context

Standardized output → content, reasoning, metadata, error codes

Goal: Make it easier to switch providers & build universal tooling.

Looking for feedback + contributors!
