OpenRouter explains the self-correcting localization pipeline behind its 7 new languages

OpenRouter launched beta localization in Simplified Chinese, Spanish, Brazilian Portuguese, German, French, Japanese and Korean, and detailed the self-correcting pipeline that keeps 16,918 English strings translated. The daily loop sends changed strings to GPT-6.1 Sol in batches of up to 40, has code reject broken placeholders and glossary violations, then uses a second call to the same model as a verifier that returns errors by severity for retries. OpenRouter says a full retranslation of the catalog into 7 languages costs about $460, versus about $7,200 at Smartling's published machine translation rate.
