Extract¶

Substantially correct. The official prompt engineering guides from OpenAI, Anthropic, and Google are all written in English. Google's Vertex AI documentation does support Spanish and Portuguese for image generation prompt language settings, but this is for image generation, not as a dedicated multilingual prompting methodology section in their prompt engineering guide.
