# BFCL English–Arabic Parallel

The single-turn test items of the **Berkeley Function Calling Leaderboard (BFCL v4)** (Patil et al., ICML 2025), each paired with its **Modern Standard Arabic** translation from **Kubrak et al. (2026)**, in one browsable table.

The two sources share item IDs and one answer key. Only the user request is translated. Tool names, tool descriptions and the accepted answers stay in English, as in Kubrak et al.'s "Arabic prompt, English tools" setting.

This is a reorganised copy, not a new benchmark. No request, tool or answer has been changed.

## Contents

3,491 items in 11 categories:

| Category | Items | What it tests | Expected behaviour |
|---|---:|---|---|
| `simple_python` | 400 | One tool offered, one call | call |
| `multiple` | 200 | 2–4 tools offered, pick one | call |
| `parallel` | 200 | One tool, several calls in one reply | call |
| `parallel_multiple` | 200 | Several tools, several calls | call |
| `irrelevance` | 240 | No offered tool fits | no call |
| `live_simple` | 258 | User-contributed request, one tool | call |
| `live_multiple` | 1,053 | User-contributed, several tools | call |
| `live_parallel` | 16 | User-contributed, several calls | call |
| `live_parallel_multiple` | 24 | User-contributed, several tools and calls | call |
| `live_irrelevance` | 884 | User-contributed, no offered tool fits | no call |
| `live_relevance` | 16 | User-contributed, some call is needed | any call |

"Live" items are real requests contributed by BFCL users. The other categories were written by the BFCL authors.

## Fields

| Field | Description |
|---|---|
| `id` | BFCL item ID, identical in both sources |
| `category` | BFCL category (table above) |
| `query_en` | User request, English (BFCL) |
| `query_ar_msa` | The same request in MSA (Kubrak et al.) |
| `system_prompt_en`, `system_prompt_ar` | System message, if the item has one (99 items) |
| `tool_names` | Names of the tools offered to the model |
| `expected_behavior` | `call`, `no_call` or `any_call` |
| `accepted_answer` | Readable form of the answer key. `a \| b` lists every value the official scorer accepts; `[optional]` means the argument may be left out |
| `tools_json` | Full JSON schemas of the offered tools |
| `ground_truth_json` | BFCL answer key in its original format (null for `no_call` and `any_call` items) |

Scoring should use the official BFCL checker, which applies the answer key as described above.

## Sources

| Source | Version used |
|---|---|
| BFCL v4: [ShishirPatil/gorilla](https://github.com/ShishirPatil/gorilla/tree/main/berkeley-function-call-leaderboard), `bfcl_eval/data/` and `possible_answer/` | commit `6ea57973c7` (2026-03-23) |
| Arabic BFCL: [kubrak94/gorilla](https://github.com/kubrak94/gorilla/tree/main/berkeley-function-call-leaderboard/bfcl_eval/data/user_prompt_ar), `user_prompt_ar/func_desc_en/func_param_desc_en/` | commit `3e9a71fef7` (2025-10-27) |

Both repositories are released under Apache-2.0. Kubrak et al. describe their translation as machine translation with limited human review.
