What is Ifstruct V1?

Ifstruct V1 is a benchmark for how precisely a model obeys the instructions it was given. The official description says: "Ifstruct V1 - instruction following structured evaluation benchmark by LiquidAI". Below we describe in simple words what benchmarks of this type generally examine.

What does it test?

Ifstruct V1 measures how precisely a model obeys the instructions it was given. In detail, it checks:

  • meeting verifiable constraints (length, format, language, layout)
  • following several constraints correctly at once
  • keeping the constraints over long, multi-turn conversations
  • not ignoring parts of the instruction while sounding plausible

How to read the score

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Frequently asked questions

What is the Ifstruct V1 benchmark?

Ifstruct V1 is a benchmark for how precisely a model obeys the instructions it was given. The official description says: 'Ifstruct V1 - instruction following structured evaluation benchmark by LiquidAI'. Below we describe in simple words what benchmarks of this type generally examine.

What does Ifstruct V1 test?

Ifstruct V1 mainly measures how precisely a model obeys the instructions it was given. Concretely, it checks: meeting verifiable constraints (length, format, language, layout); following several constraints correctly at once; keeping the constraints over long, multi-turn conversations.

How is the Ifstruct V1 score calculated?

The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.

Where do I get Ifstruct V1 data and scores?
