03 · About

What it is.

Check context limits, tool support, and modality fit before you wire a model into production.

LLM Compatibility Checker helps teams pick a model that actually matches the job: context window, function calling, vision, JSON mode, and pricing tier. It is the pre-flight checklist we use before committing a client build to a single vendor.
