Summary

Adds documentation clarifying the absence of cache_write_input_per_million pricing rates for the three hand-added GPT-5.6 Bedrock model entries (openai.gpt-5.6-luna, openai.gpt-5.6-terra, openai.gpt-5.6-sol).

Details

The comment documents that:

  • None of these three hand-added entries carry a cache_write_input_per_million rate
  • This matches the pattern for all other OpenAI-family models in the registry (no OpenAI models have this field modeled)
  • This is consistent with but NOT independently verified against OpenAI/Bedrock pricing docs for GPT-5.6
  • The gap remains unclear: whether Bedrock simply doesn't charge distinct cache-write rates, or whether pricing data is incomplete

Motivation

Provides context for future maintainers investigating the pricing model for these Bedrock entries and helps prevent accidental introduction of cache-write rates without proper verification against official pricing documentation.

The hand-added openai.gpt-5.6-luna/-terra/-sol registry entries (7791056)
omit cache_write_input_per_million. This matches every other OpenAI-family
model in models.json, but that omission was never independently confirmed
against OpenAI/Bedrock pricing docs for GPT-5.6 specifically. Document the
gap next to the spec that already pins these three entries' pricing, so
it's revisited once models.dev or AWS publish real data.

Reviewed this PR — it only adds an explanatory comment to a spec file (spec/ruby_llm/models_gpt_5_6_bedrock_spec.rb) documenting a known gap in pricing data for three hand-added model entries. No logic, behavior, or test assertions changed. Nothing actionable found; no inline comments.
