Description

I've noticed that some OpenRouter Anthropic models don't extend from their anthropic counterparts.

For example, openrouter/models/claude-sonnet-4.6.toml seems to be an outdated version of anthropic/models/claude-sonnet-4-6.toml. (1M token limit is now the default and doesn't cost extra).

Research direction

Compare providers/openrouter/models/anthropic/claude-sonnet-4.6.toml with providers/anthropic/models/claude-sonnet-4-6.toml, then inspect nearby OpenRouter Anthropic model files for the expected inheritance pattern. Update the outdated model metadata so the OpenRouter entries extend their Anthropic counterparts and reflect the current token-limit pricing, then verify the affected model files.
