OpenAPI path parameter format

The path parameters described in the OpenAPI REST document do not seem to follow the spec on how path parameters are described: https://spec.openapis.org/oas/v3.1.0#path-templating.

Is this intentional? Does some build tooling remove these dollar signs? If so, where can people find a usable built output?

Start with specification/protocol/open_inference_rest.yaml at lines 42, 81, and 105, and compare the path parameters with the linked OpenAPI path-templating specification. Trace the repository's build tooling, if present, to determine whether the dollar signs are removed; the work is done when the parameter format is corrected or the intentional transformation and usable built output are documented.
