Module: ActiveHarness::Pricing::Normalizer

Defined in:
lib/active_harness/pricing/normalizer.rb

Overview

Converts any model identifier or display name to a canonical lookup key.

Works on both raw provider model IDs and human-readable display names, producing the same key for the same model regardless of source.

Examples:

Normalizer.to_key("Mistral Nemo")                                # => "mistral-nemo"
Normalizer.to_key("mistralai/mistral-nemo")                      # => "mistral-nemo"
Normalizer.to_key("GPT-4o")                                      # => "gpt-4o"
Normalizer.to_key("gpt-4o")                                      # => "gpt-4o"
Normalizer.to_key("claude-3-5-haiku-20241022")                   # => "claude-3-5-haiku"
Normalizer.to_key("global.anthropic.claude-haiku-4-5-20251001-v1:0") # => "claude-haiku-4-5"
Normalizer.to_key("models/gemini-2.5-flash")                     # => "gemini-2-5-flash"
