-# Realistic-pricing starter for llm_observability. Drop this into the
-# directory you point the proxy at via --plugin-data-dir, then reference it
-# from the target's plugin config:
-#
-#   plugins:
-#     - id: llm_observability
-#       enabled: true
-#       params:
-#         pricing_path: pricing.yaml

-# Values are USD per 1_000 tokens. Public list prices drift; treat this as a
-# starting point and keep your production copy current.
