IndicIFEval

Paper | GitHub

Instruction-following benchmarks remain predominantly English-centric, leaving a critical evaluation gap for the hundreds of millions of Indic language speakers. We introduce IndicIFEval, a benchmark evaluating constrained generation of LLMs across 14 Indic languages using automatically verifiable, rule-based instructions. It combines two complementary tracks: IndicIFEval-Trans, translated prompts from IFEval carefully localized for Indic contexts, and IndicIFEval-Ground, synthetically generated instructions grounded in native Indic content.

Overview

14 Indic Languages: Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Nepali, Odia, Punjabi, Sanskrit, Tamil, Telugu, Urdu

We implement the same format of the original IFEval to allow a streamlined and compatible evaluation framework across all the languages. The table below details the column names, their respective data types, and a brief description of their contents.

Column Name	Data Type	Description
key	int64	Unique identifier for each evaluation instance.
prompt	str	The natural language instruction presented to the model.
instruction_id_list	List of str	Identifiers specifying which format or constraint checks apply to the prompt.
kwargs	List of dict	Parameter values associated with each constraint specified in the instruction list.

Translated and localized prompts from the English IFEval benchmark, carefully filtered and manually verified by native speakers for cultural suitability and translation quality
