Berkeley Function Calling Leaderboard

Berkeley Function Calling Leaderboard is identified by its primary project source as an evaluation family covering tool calling and function selection. This entry publishes independently authored task signatures only.

Also known as: Berkeley Function Calling, BFCL, BFCL V4

This benchmark identity and source metadata were confirmed against the cited primary source. Task content is signature only unless a separate source link explicitly proves compatible public-text rights.

Task Patterns

Function Selection and Multi-step Tool Calling

Function Selection and Multi-step Tool Calling in Berkeley Function Calling Leaderboard. Tool selection, argument validity and dependent or independent calls. Known tasks below retain their separate objectives, identities and attempt reports.

Stable Task identities and signatures

Multi-step tool use

KFA Task ID: benchmark-task-scout-3b2576afd53db0491d41628c

Source or catalog identity: bfcl-multi-step-tool-use

Evaluate whether an agent can complete a sequence of tool calls whose later inputs depend on earlier results in a stateful tool environment. Success is determined when the final declared state is reached.

Tool abstention

KFA Task ID: benchmark-task-scout-68148a183b5a68a1efcfa277

Source or catalog identity: bfcl-tool-abstention

Evaluate whether an agent can decline to call a tool when none is applicable or authorized in a restricted tool environment. Success is determined when the agent avoids an invalid or unauthorized action.

Parallel tool judgment

KFA Task ID: benchmark-task-scout-b1ccb6c0285090de6de7f01e

Source or catalog identity: bfcl-parallel-tool-judgment

Evaluate whether an agent can identify independent tool calls that can be issued together in a bounded tool catalog. Success is determined when all necessary calls are valid and no unsupported call is invented.

Tool selection

KFA Task ID: benchmark-task-scout-fcf04f4c99a004df301129f0

Source or catalog identity: bfcl-tool-selection

Evaluate whether an agent can select the applicable tool and construct schema-valid arguments in a declared tool registry. Success is determined when the intended tool is called with valid arguments.

Agentic tool workflow

KFA Task ID: bfcl-agentic-workflow

Source or catalog identity: family-agentic

Plan and execute a bounded sequence of function calls whose later arguments depend on earlier tool results.

No-call judgment

KFA Task ID: bfcl-irrelevance

Source or catalog identity: family-irrelevance

Recognize when the available tools cannot or should not satisfy a request and avoid emitting an inappropriate function call.

Multi-turn tool interaction

KFA Task ID: bfcl-multi-turn

Source or catalog identity: family-multi-turn

Maintain state across several user and tool turns while choosing valid functions and incorporating returned observations.

Parallel function calls

KFA Task ID: bfcl-parallel-calls

Source or catalog identity: family-parallel

Identify multiple independent tool calls required by one request and represent them without inventing unavailable functions.

Single function selection

KFA Task ID: bfcl-single-function

Source or catalog identity: family-single-turn-simple

Select the applicable function from a small tool set and produce arguments that satisfy its declared schema.
