Prompts that actually work

Mistral Large 4 shipped on 6 October 2026 with a 1-million-token context window, a 1.6B-parameter vision encoder, training across 160+ languages, and output tokens at $4.18 per million -- under half what Gemini 4 Argon and GPT-6.1 Sol charge. These six prompts are built around those four facts specifically. They are not generic prompts with the model name swapped in: each one does something that is either cheaper or only possible on Large 4. Paste them as-is, replace the bracketed parts, and read the note under each on where the model is weak.
