Overview

This model analyzes the diffusion of AI capabilities from frontier laboratories to progressively broader populations of actors. It examines proliferation mechanisms, control points, and the relationship between diffusion speed and risk accumulation. The central question: How fast do dangerous AI capabilities spread from frontier labs to millions of users, and which intervention points offer meaningful leverage?

Key findings show proliferation follows predictable tier-based patterns, but time constants are compressing dramatically. Capabilities that took 24-36 months to diffuse from Tier 1 (frontier labs) to Tier 4 (open source) in 2020 now spread in 12-18 months. Projections suggest 6-12 month cycles by 2025-2026, fundamentally changing governance calculus.

The model identifies an “irreversibility threshold” where proliferation cannot be reversed once capabilities reach open source. This threshold is crossed earlier than commonly appreciated—often before policymakers recognize capabilities as dangerous. High-leverage interventions must occur pre-proliferation; post-proliferation controls offer diminishing returns as diffusion accelerates.

Risk Assessment Framework

Risk Dimension	Current Assessment	2025-2026 Projection	Evidence	Trend
Diffusion Speed	High	Very High	50% reduction in proliferation timelines since 2020	Accelerating
Control Window	Medium	Low	12-18 month average control periods	Shrinking
Actor Proliferation	High	Very High	Tier 4 access growing exponentially	Expanding
Irreversibility Risk	High	Extreme	Multiple capabilities already irreversibly proliferated	Increasing

Proliferation Tier Analysis

Actor Tier Classification

The proliferation cascade operates through five distinct actor tiers, each with different access mechanisms, resource requirements, and risk profiles.

Tier	Actor Type	Count	Access Mechanism	Diffusion Time	Control Feasibility
1	Frontier Labs	5-10	Original development	-	High (concentrated)
2	Major Tech	50-100	API/Partnerships	6-18 months	Medium-High
3	Well-Resourced Orgs	1K-10K	Fine-tuning/Replication	12-24 months	Medium
4	Open Source	Millions	Public weights	18-36 months	Very Low
5	Individuals	Billions	Consumer apps	24-48 months	None

Historical Diffusion Data

Analysis of actual proliferation timelines reveals accelerating diffusion across multiple capability domains:

Capability	Tier 1 Date	Tier 4 Date	Total Time	Key Events
GPT-3 level	May 2020	Jul 2022	26 months	OpenAI → HuggingFace release
DALL-E level	Jan 2021	Aug 2022	19 months	OpenAI → Stable Diffusion
GPT-4 level	Mar 2023	Jan 2025	22 months	OpenAI → DeepSeek-R1
Code generation	Aug 2021	Dec 2022	16 months	Codex → StarCoder
Protein folding	Nov 2020	Jul 2021	8 months	AlphaFold → ColabFold

Mathematical Model

Core Risk Equation

Total proliferation risk combines actor count, capability level, and misuse probability:

$R_{\text{total}}(t) = \sum_{i=1}^{5} N_i(t) \cdot C_i(t) \cdot P_{\text{misuse},i}$

Where:

• $N_i(t)$ = Number of actors in tier $i$ with access at time $t$
• $C_i(t)$ = Capability level accessible to tier $i$ at time $t$
• $P_{\text{misuse},i}$ = Per-actor misuse probability for tier $i$

Diffusion Dynamics

Each tier transition follows modified logistic growth with accelerating rates:

$N_i(t) = \frac{N_{i,\max}}{1 + e^{-k_i(t - t_{0,i})}}$

The acceleration factor captures increasing diffusion speed:

$k_i(t) = k_{i,0} \cdot e^{\alpha t}$

With $\alpha \approx 0.15$ per year, implying diffusion rates double every ~5 years. This matches observed compression from 24-36 month cycles (2020) to 12-18 months (2024).

Risk by Actor Type

Misuse Probability Assessment

Different actor types present distinct risk profiles based on capability access and motivation:

Actor Type	Estimated Count	Capability Access	P(Access)	P(Misuse|Access)	Risk Weight
Hostile state programs	5-15	Frontier	0.95	0.15-0.40	Very High
Major criminal orgs	50-200	Near-frontier	0.70-0.85	0.30-0.60	High
Terrorist groups	100-500	Moderate	0.40-0.70	0.50-0.80	High
Ideological groups	1K-10K	Moderate	0.50-0.80	0.10-0.30	Medium
Malicious individuals	10K-100K	Basic-Moderate	0.60-0.90	0.01-0.10	Medium (scale)

Expected Misuse Events

Even low individual misuse probabilities become concerning at scale:

$E[\text{misuse events}] = \sum_i N_i \cdot P(\text{access})_i \cdot P(\text{misuse}|\text{access})_i$

For Tier 4-5 proliferation with 100,000 capable actors and 5% misuse probability, expected annual misuse events: 5,000.

Current State & Trajectory

Recent Developments

The proliferation landscape has shifted dramatically since 2023:

2023 Developments:

• LLaMA leak↗ demonstrated fragility of controlled releases
• LLaMA 2 open release↗ established new norm for frontier model sharing
• U.S. export controls↗ on advanced semiconductors implemented

2024-2025 Developments:

• Qwen 2.5↗ and Mistral↗ continued aggressive open-source strategy
• Chinese labs increasingly releasing frontier capabilities openly

2025-2030 Projections

Accelerating Factors:

• Algorithmic efficiency reducing compute requirements ~2x annually
• China developing domestic chip capabilities to circumvent controls
• Open-source ideology gaining ground in AI community
• Economic incentives for ecosystem building through open models

Decelerating Factors:

• Growing awareness of proliferation risks among frontier labs
• Potential regulatory intervention following AI incidents
• Voluntary industry agreements on responsible disclosure
• Technical barriers to replicating frontier training runs

Key Uncertainties

Critical Unknown Parameters

Uncertainty	Impact on Model	Current State	Resolution Timeline
Chinese chip development	Very High	2-3 generations behind	3-7 years
Algorithmic efficiency gains	High	~2x annual improvement	Ongoing
Open vs closed norms	Very High	Trending toward open	1-3 years
Regulatory intervention	High	Minimal but increasing	2-5 years
Major AI incident	Very High	None yet	Unpredictable

Model Sensitivity Analysis

The model is most sensitive to three parameters:

Diffusion Rate Acceleration (α): 10% change in α yields 25-40% change in risk estimates over 5-year horizon. This parameter depends heavily on continued algorithmic progress and open-source community growth.

Tier 4/5 Misuse Probability: Uncertainty ranges from 1-15% create order-of-magnitude differences in expected incidents. Better empirical data on malicious actor populations is critical.

Compute Control Durability: Estimates ranging from 3-15 years until circumvention dramatically affect intervention value. China’s semiconductor progress is the key uncertainty.

Research Gaps

Several critical uncertainties limit model precision and policy effectiveness:

Empirical Proliferation Tracking: Systematic measurement of capability diffusion timelines across domains remains limited. Most analysis relies on high-profile case studies rather than comprehensive data collection.

Reverse Engineering Difficulty: Time and resources required to replicate capabilities from limited information varies dramatically across capability types. Better understanding could inform targeted protection strategies.

Actor Intent Modeling: Current misuse probability estimates rely on theoretical analysis rather than empirical study of malicious actor populations and motivations.

Control Mechanism Effectiveness: Rigorous testing of governance interventions is lacking. Most effectiveness estimates derive from analogies to other domains rather than AI-specific validation.

Defensive Capability Development: The model focuses on capability proliferation while ignoring parallel development of defensive tools that could partially offset risks.
