When will OpenAI achieve AGI?

The AI industry has shifted from pure scaling to efficiency. This transition from a parameter-centric scaling paradigm to a compute-optimal approach has fundamentally altered how progress in large language models (LLMs) is achieved. This shift, combined with increasing architectural complexity like Mixture-of-Experts (MoE) in GPT-4, indicates a decline in the effective scaling coefficient. This means that raw increases in parameters or compute now yield progressively smaller performance gains, shifting the focus from pure scale to efficiency and advanced post-training techniques.

Diminishing returns stem from critical data and compute bottlenecks. Data exhaustion is a significant challenge, as the supply of high-quality public text data is dwindling, prompting a pivot towards synthetic or multimodal data. Compute constraints also play a role, with training costs reaching astronomical figures, necessitating a focus on algorithmic and architectural efficiency over brute-force scaling. Furthermore, inherent architectural limitations of Transformers and difficulties in evaluating increasingly powerful models contribute to the slowdown in scaling efficacy. GPT-5 is expected to feature a unified architecture for "fast" and "thinking" modes, representing an innovation over simple scaling.

The declining coefficient significantly impacts AGI timeline predictions. While earlier forecasts based on exponential growth suggested near-term AGI, experts now generally project a wider window of 5 to 30 years, with a median around 10-20 years. This longer-term view is reflected in prediction markets, which acknowledge that progress is no longer a simple function of adding more compute. Despite this, 2026 is anticipated to bring significant tangible AI advancements, potentially fueling public perception of imminent AGI, though an "AI backlash" due to costs and perceived overpromising remains a possibility.

Dylan Scandinaro's role is influential, lacking direct deployment veto power. Appointed OpenAI's Head of Preparedness on February 3, 2026, his mandate is to identify, test, and mitigate severe risks associated with powerful AI models. However, public information indicates that he does not possess direct, unilateral 'go/no-go' veto authority over model deployments. This crucial power is formally vested in OpenAI's Safety and Security Committee (SSC), a subcommittee of the board. Scandinaro's role is therefore one of powerful influence and expertise, providing critical input to these formal governance bodies.

Scandinaro lacks independent budget controls, yet his role impacts AGI timelines. There is no public documentation or credible reporting suggesting he can independently requisition a significant portion, specifically over 10%, of OpenAI's training compute for safety research. For AGI timelines, his position presents a dual impact: robust preparedness could introduce process-driven delays, but it simultaneously de-risks aggressive scaling by preventing catastrophic safety failures. This could paradoxically accelerate AGI development by ensuring a more stable path, leading prediction markets to potentially increase the probability of short-term friction while decreasing the likelihood of a catastrophic, long-term setback.

OpenAI's 2026 compute deployment hinges on its custom AI accelerators. The primary risk has shifted from NVIDIA GPU supply constraints to the successful execution of OpenAI's custom AI accelerator program utilizing TSMC's 3nm process. While NVIDIA's H100/H200 GPUs are now readily available, the company's ambitious move to in-house silicon introduces substantial design, tape-out, and yield ramp uncertainties, which are the most critical factors threatening its ability to meet compute targets.

Securing TSMC's 3nm capacity and energy infrastructure poses hurdles. TSMC is aggressively expanding its 3nm production, projected to reach 160,000 wafers per month by late 2025 with high yield rates. However, OpenAI, as a new market entrant, must compete for this fiercely contested capacity against major players like Apple and NVIDIA, who are also consuming significant portions for their next-generation chips. Beyond silicon, a long-term, systemic bottleneck remains the availability of multi-gigawatt energy infrastructure, involving lengthy lead times for grid interconnection and substation construction, which could ultimately cap deployment regardless of chip availability.

Delays in custom chips could lead to significant compute shortfalls. A six-to-nine-month delay in OpenAI's custom chip program could result in a 20-30% annualized compute shortfall, easily exceeding the critical 15% threshold that would trigger a non-negotiable timeline delay. Even a pivot to NVIDIA hardware as a fallback option would introduce significant procurement, integration, and software re-adaptation challenges, still potentially resulting in a 10-20% shortfall. Such a substantial deployment discrepancy would likely push out AGI timeline predictions and could cede competitive ground to rivals.

Research projects anticipate that the open-source community will significantly contribute to novel AI architectural breakthroughs. Specifically, 60% (6 out of 10) of the most-cited AI research papers in 2026 introducing novel architectural or algorithmic breakthroughs are projected to originate from the open-source community. These innovations encompass non-Transformer architectures such as State-Space Models (SSMs) like Mamba-3 and linear-time Recurrent Neural Networks (RNNs) like RWKV. Such open-source developments aim to mitigate computational and memory bottlenecks, delivering high performance with increased efficiency.

OpenAI's strategy favors scaling existing architectures, potentially isolating them from crucial progress. In contrast to open-source efforts, OpenAI's contributions are expected to concentrate on scaling existing Transformer-based architectures. This leverages their hyperscale computing infrastructure to achieve new state-of-the-art benchmarks. This divergence in research focus carries critical implications for the trajectory toward Artificial General Intelligence (AGI). The open-source ecosystem, characterized by rapid iteration and diverse exploration with over 500 model releases weekly, suggests that AGI may not exclusively rely on scaling a single architecture. Consequently, OpenAI's closed strategy could become a long-term strategic liability, potentially isolating them from a broader pool of foundational innovation.

Open-source algorithmic advances are closing performance gaps rapidly and cost-effectively. Beyond architectural innovations, the open community is also spearheading algorithmic advancements, including self-verifying AI agents and sophisticated post-training model refinement techniques. These techniques enable smaller open models to compete effectively with proprietary ones, often achieving 70-90% cost savings. This rapid progress indicates that open-source models are quickly narrowing performance gaps, reaching 89-90% of proprietary model performance and catching up at an approximate rate of three months. This trend suggests that OpenAI's lead in fundamental research might be more fragile than commonly perceived. Therefore, a hybrid approach involving selective open-sourcing could offer proprietary laboratories a method to mitigate risks and benefit from external contributions.

OpenAI's succession plan hinges on AGI demonstrating superior governance capabilities. This framework outlines a paradigm shift involving the potential handover of leadership functions to an AGI, utilizing a dual-trigger mechanism that separates internal conviction of AGI's existence from its external public declaration and operational integration. The AGI must prove to be a superior steward of the company's mission, capable of managing resources and ethical landscapes beyond human capacity. Human oversight is maintained through the Safety and Security Committee, which continuously reviews safety protocols to ensure controlled and aligned AI capabilities escalate appropriately.

Prometheus milestones define specific technical, cognitive, and economic AGI benchmarks. These internal "Prometheus" milestones comprise a comprehensive portfolio of assessments to prove AGI's emergence through technical and cognitive supremacy, as well as economic and autonomous value generation. Key technical benchmarks include achieving over 99% on the ARC-AGI-2 benchmark, designed to test novelty, efficiency, and long-horizon task completion, alongside mastery of dynamic video analysis. Furthermore, autonomous AI agents must demonstrate proactive decision-making, tool creation, and scientific discovery in complex simulated environments without human intervention. Economically, the AGI must master the GDPval metric across 44 occupations, performing tasks 100 times faster and cheaper, and be credibly projected to generate $100 billion in annual profits.

External verification and market alignment validate AGI before public announcement. Achieving these internal milestones necessitates rigorous external verification prior to any public declaration. This includes comprehensive third-party red teaming and audits to replicate results and conduct adversarial testing, ensuring the system's robustness against manipulation and confirming high safety and alignment standards through a formal consensus statement. The framework also considers novel verification mechanisms like prediction market alignment, where compelling evidence must drive relevant markets to near-certainty (e.g., >95% probability) to provide an external, financially-motivated confirmation of AGI, acting as a crucial check against internal bias.

OpenAI's trajectory toward AGI is propelled by several bullish catalysts. Frontier model releases are key, with GPT-Next, announced in September 2024, anticipated to be 100 times more powerful than GPT-4, and the continued deployment of advanced models like GPT-5.1 and GPT-5.2. Breakthroughs in AI reasoning and agency are also significant, including the "o3" model achieving an 87.5% score on the ARC-AGI benchmark, the emergence of "stumbling agents" by late 2025, and the prediction of fully automated AI research by 2027-2028. The operationalization of massive "Stargate" datacenters, designed for training models with 10^28 FLOP, signals a rapid increase in computational power, further bolstering the outlook. OpenAI CEO Sam Altman's stated confidence in knowing how to build AGI also indicates strong internal progress. However, several bearish catalysts could delay or prevent AGI by 2030. Increasing regulatory scrutiny and the implementation of stringent AI safety measures could slow development and introduce unforeseen limitations. Technical bottlenecks persist, particularly the challenge of achieving true autonomy and understanding for "ill-defined, high-context work," which some experts believe requires fundamentally new algorithmic breakthroughs beyond mere scaling. Resource and economic constraints, such as potential bottlenecks in compute, investment, and research talent around 2030, or a collapse in the profitability of frontier models, could limit the massive investment needed. Moreover, some expert forecasts, including a January 2026 revision by a former OpenAI researcher, suggest a longer timeline for "superintelligence," pushing the horizon to 2034 and indicating a slower pace than initially projected.
