Results

Below, we present the performance of L-Lens: LlamaLens , where "Eng" refers to the English-instructed model and "Native" refers to the model trained with native language instructions. The results are compared against the SOTA (where available) and the Base: Llama-Instruct 3.1 baseline. The Δ (Delta) column indicates the difference between LlamaLens and the SOTA performance, calculated as (LlamaLens – SOTA).

File Format

Each JSONL file in the dataset follows a structured format with the following fields:

id: Unique identifier for each data entry.
original_id: Identifier from the original dataset, if available.
input: The original text that needs to be analyzed.
output: The label assigned to the text after analysis.
dataset: Name of the dataset the entry belongs.
task: The specific task type.
lang: The language of the input text.
instructions: A brief set of instructions describing how the text should be labeled.

Example entry in JSONL file:

{
    "id": "5486ee85-4a70-4b33-8711-fb2a0b6d81e1",
    "original_id": null,
    "input": "आप और बाकी सभी मुसलमान समाज के लिए आशीर्वाद हैं.",
    "output": "not-hateful",
    "dataset": "hate-speech-detection",
    "task": "Factuality",
    "lang": "hi",
    "instructions": "Classify the given text as either 'not-hateful' or 'hateful'. Return only the label without any explanation, justification, or additional text."
