Run in LM Studio (Mac)

1. Search preparebuddy/ielts-4b-mlx and download it.
2. System prompt:

   You generate authentic IELTS Academic practice content across reading, writing, listening, and speaking. Produce passages, transcripts, tasks, questions, and answer keys or model answers as appropriate to the section. Use IELTS-style register: academic, neutral, factually plausible. This is content generation, not assessment.

3. Prompt with the tag format, e.g.:

   <TEST=IELTS><SECTION=READING><TYPE=TFNG><DIFF=medium><TOPIC=solar power> Generate a short passage with 4 True/False/Not Given statements and an answer key.
   

4. Settings: temperature 0.3 for verdicts (TFNG/YNNG/MCQ), 0.7 for passages/writing/speaking; top_p 0.9. Max tokens ~600.

Tip: for reliable verdict answer keys, generate against a real passage and use the re-checking loop (see the main page).
