LiveCodeBench
LiveCodeBench is identified by its primary project source as an evaluation family covering code generation and program reasoning. This entry publishes independently authored task signatures only.
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.

Stable Task identities and signatures
Constraint-aware solution
KFA Task ID: benchmark-task-scout-326942adc9af727b60be0417
Source or catalog identity: livecodebench-constraint-aware-solution
Evaluate whether an agent can construct a solution while respecting declared resource and interface constraints in a deterministic code evaluator. Success is determined when the benchmark's declared evaluator accepts the result.
Repair after feedback
KFA Task ID: benchmark-task-scout-46be5a5689ebb48dd033c5a9
Source or catalog identity: livecodebench-repair-after-feedback
Evaluate whether an agent can repair an incorrect program after bounded evaluator feedback in an isolated coding environment. Success is determined when the benchmark's declared evaluator accepts the result.
Execution reasoning
KFA Task ID: benchmark-task-scout-59ce437b2c47442ee566c2e9
Source or catalog identity: livecodebench-execution-reasoning
Evaluate whether an agent can reason about the observable behavior of a supplied program in a declared programming-language runtime. Success is determined when the predicted behavior matches the evaluator.
Functional code generation
KFA Task ID: benchmark-task-scout-e6f20846fa43711681bdf7f5
Source or catalog identity: livecodebench-functional-code-generation
Evaluate whether an agent can produce a program satisfying a bounded functional specification in a versioned code-execution sandbox. Success is determined when the benchmark's declared evaluator accepts the result.
Code execution reasoning
KFA Task ID: livecodebench-code-execution
Source or catalog identity: scenario-codeexecution
Reason about a supplied program and determine its execution behavior for a bounded input without exposing evaluator tests.
Code generation
KFA Task ID: livecodebench-code-generation
Source or catalog identity: scenario-codegeneration
Produce a program for a newly released competitive-programming problem under stated input, output, and resource constraints.
Test output prediction
KFA Task ID: livecodebench-output-prediction
Source or catalog identity: scenario-testoutputprediction
Predict the observable output of a program for a specified test case using language semantics and control-flow reasoning.
Self repair
KFA Task ID: livecodebench-self-repair
Source or catalog identity: scenario-selfrepair
Revise a previously generated program after test feedback so that the corrected version satisfies the original constraints.
Recent-problem evaluation
KFA Task ID: livecodebench-time-window
Source or catalog identity: family-time-window
Solve code problems selected from a declared recent release window to reduce contamination from older training material.
