BEANS-Next
BEANS-Next evaluates audio-language models on 45 bioacoustic tasks, with 37,718 examples and all evaluation audio included.
| Tier | Focus | Examples |
|---|---|---|
| 1 | Acoustic perception | 4,403 |
| 2 | Semantic recognition | 13,666 |
| 3 | Structural and relational reasoning | 18,609 |
| 4 | Multiple audio clips and in-context learning | 1,040 |
The five headline Tier 4 tasks contain the exact 200 examples per task selected for the paper evaluation. The additional zebra matching task contains all 40 examples. Example IDs use the repository's canonical hash format.
The Gibbon support order and answer letters match the evaluated paper subset. They supersede the option-balancing order in the previous anonymous release.
Quick start
Load the test split, then download the audio for an example:
from datasets import load_dataset
from huggingface_hub import hf_hub_download
import soundfile as sf
repo_id = "iclr2027anon/BEANS-Next"
dataset = load_dataset(repo_id, split="test")
row = dataset[0]
paths = row["audio_paths"]
audio = [
sf.read(hf_hub_download(repo_id, f"test/{path}", repo_type="dataset"))
for path in paths
]
load_dataset loads metadata; the audio downloads separately. Each item in audio contains a waveform and its sample rate.
Give the model the user message in messages and the audio. Use the assistant message as the expected answer for scoring.
For tier 4, supply all reference clips followed by the query, in the order shown above. Keep repeated clips. The supplied audio is ready to use; do not apply source crop times again.
Columns
| Columns | Meaning |
|---|---|
id |
Example ID: beans_next_ followed by 32 hexadecimal characters. |
tier, task |
Tier number and task name. |
messages |
User prompt and expected assistant answer. |
audio_paths |
Ordered audio paths relative to test/; one clip for tiers 1–3, references then query for tier 4. |
license |
Available source license information. |
source_datasets, source_audio_ids, source_file_paths, source_urls |
Source names, IDs, filenames, and links for each clip, in audio order. |
source_id_types |
Type of each source ID. |
audio_start_seconds, audio_end_seconds |
Crop boundaries within source recordings, in seconds. |
metadata |
Task-specific annotations as JSON text. |
Join predictions by id.
