Research	R0028 — Prompt Engineering Claims
Run	2026-03-26
Claim	C019

Claim: The major prompt engineering guides from OpenAI, Anthropic, and Google are written in English with no dedicated multilingual prompting sections, though Google provides minimal Spanish and Portuguese support.

BLUF: 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.

Probability: Very likely (80-95%) | Confidence: Medium
