lmstudio-ai/lmstudio-js#253 is an lmstudio-js feature request to also publish a data file that specifies how to map LlmPredictionConfig, LlmLoadModelConfig, and EmbeddingLoadModelConfig attributes to KvConfigStack field names.
This corresponding Python SDK issue covers updating the SDK data model generator to add that data file into the lmstudio package, and updating _kv_config.py to use it when mapping configuration keys, rather than maintaining the mappings independently of lmstudio-js.
