The same 2025 study found that even with extensive background knowledge in the prompt, language models still struggled with the hardest domain-specific tasks.

Open the original- What it measures
- The authors compared their longest prompts with the original short ones and found that the longest prompts still left the models well short of human-level scores.
- What it does not show
- The tasks were classification tasks in finance, law and other specialist areas. The result says a longer prompt does not guarantee a correct answer.
