Greptile Summary

This PR adds pricing and capability metadata for the openrouter/minimax/minimax-m2.7 model to both model_prices_and_context_window.json and its backup, resolving #24601.

• Adds openrouter/minimax/minimax-m2.7 entry with correct pricing: input 3e-07 ($0.30/1M), output 1.2e-06 ($1.20/1M), cache read 6e-08 ($0.06/1M)
• Sets max_input_tokens: 204800 and max_output_tokens: 131072, consistent with OpenRouter's published specs
• Capability flags (supports_function_calling, supports_tool_choice, supports_reasoning, supports_prompt_caching) all match the OpenRouter model page
• Both files (model_prices_and_context_window.json and the backup) are updated identically and in sync
• Entry structure follows the same pattern as the sibling openrouter/minimax/minimax-m2.5 entry

Confidence Score: 5/5

Safe to merge — additive-only change to a data file with no logic modifications.

The change is a pure data addition to both JSON pricing files. All numeric values are arithmetically consistent with the PR description, the entry structure mirrors the existing minimax model entries, and both files are kept in sync. No code paths are modified.

No files require special attention.

Important Files Changed

Filename	Overview
