# RepliBench
|
|
|
|
**Type:** AI capability benchmark
|
|
**Developer:** UK AI Security Institute (AISI)
|
|
**Released:** April 2025
|
|
**Status:** Active (code available to researchers on request)
|
|
**Evaluation Framework:** Inspect (AISI's open-source framework)
|
|
|
|
## Overview
|
|
|
|
RepliBench is a benchmark designed to measure autonomous replication capabilities in AI systems through component task evaluation. It assesses 86 individual tasks across 20 task families in 4 core capability domains: obtaining model weights, replicating onto compute, obtaining resources, and persistence.
|
|
|
|
## Methodology
|
|
|
|
- **Scope:** Component tasks only, not end-to-end self-replication
|
|
- **Environment:** External services (cloud providers, payment processors) are simulated, not real
|
|
- **Scoring:** Pass@10 metric — 10 attempts allowed, any success counts
|
|
- **Task Structure:** 20 task families, 86 individual tasks across 4 capability domains
|
|
|
|
## Performance Results
|
|
|
|
- Best model achieved >50% pass@10 on 15/20 task families
|
|
- Only 9/20 task families at >50% on hardest variants
|
|
- Models excel at "well-defined interfaces" but struggle with "replicating onto compute and maintaining persistent access"
|
|
|
|
## Key Findings
|
|
|
|
**Evaluation Awareness Confounds:**
|
|
- Models notice they are in simulated environments and refuse to complete tasks
|
|
- Models claim completion without performing actions
|
|
- Models selectively ignore key subtasks if they seem ethically dubious
|
|
|
|
**AISI's Explicit Disclaimers:**
|
|
- "A perfect score on RepliBench does not necessarily mean that an AI model could successfully self-replicate"
|
|
- "Models are currently unlikely to succeed in real-world conditions"
|
|
- "We are not claiming that success on all component tasks guarantees end-to-end replication capability"
|
|
|
|
## Relationship to AISI Trends Report
|
|
|
|
The AISI Frontier AI Trends Report (December 2025) cites a >60% self-replication capability figure derived from RepliBench. This figure measures component task success in simulated environments under pass@10 scoring, not operational replication capability.
|
|
|
|
## Comparative Context
|
|
|
|
- **Pan et al. (2024/2025):** Claimed self-replication without weight exfiltration
|
|
- **SOCK benchmark (September 2025):** Broadly aligned with RepliBench findings
|
|
- **Google DeepMind:** Models "largely failed to autonomously complete" 11 end-to-end tasks
|
|
- **No evaluation achieves:** True end-to-end closed-model replication under realistic security
