The AGI scaling law pivot

For years, the AI industry lived by a single commandment: scale everything. More parameters, more data, more compute. But the first signs of diminishing returns are now visible—and the industry is pivoting to a new frontier: smarter architectures, inference-time reasoning, and the persistence that current models lack. The scaling era is not over; it is entering a new phase.
The Law That Defined an Era
Neural scaling laws, first formalised by OpenAI in 2020, provided a precise roadmap: model performance improves predictably as you increase parameters, data, and compute. The relationship held across many orders of magnitude, making scaling a reliable engineering strategy rather than a gamble.
This is why companies have spent hundreds of billions on GPU clusters. If the scaling laws hold, building a bigger model is almost guaranteed to produce a better one. But the curve hides a crucial detail: improvement follows a power law—you need exponentially more compute for each linear gain in performance. Going from GPT-3 to GPT-4 was dramatically more expensive than going from GPT-2 to GPT-3.
The returns per dollar are definitely getting harder. And the field is beginning to ask whether we are approaching the practical limits of brute-force scaling.
The Wall and the Contenders
Several indicators suggest the scaling paradigm is reaching a turning point. Ilya Sutskever has publicly stated that "pretraining as we know it will end," acknowledging that "we have achieved peak data" and "there is only one internet". Sam Altman has countered that "there is no wall," and Dario Amodei has said that "scaling is probably going to continue". But even the believers are pivoting their strategies.
The economic reality is equally telling. Aggregated US hyperscaler AI capex for 2026 is projected at $660–690 billion, up from $380–410 billion in 2025—a near-doubling in a single year. Yet even as investment surges, the returns on that investment are becoming less certain. As one analysis put it, "spending is projected to outpace earnings by year-end, pushing net free cash flow into negative territory until late 2027."
Test-Time Compute: A New Kind of Scaling
The most significant pivot is toward test-time compute—scaling computation during inference rather than during training. OpenAI's o1 and o3 models have demonstrated that giving a model more time to "think" before responding can unlock capabilities that training-time scaling alone cannot achieve.
Noam Brown, a researcher at OpenAI, illustrated the potential: "having a bot think for just 20 seconds in a hand of poker got the same boosting performance as scaling up the model by 100,000x and training it for 100,000 times longer". This is not a marginal improvement. It is a paradigm shift in how we measure the relationship between intelligence and resources.
The approach, known as "chain of thought" reasoning, allows the model to break complex problems into steps and self-correct along the way. It comes with trade-offs: higher computational costs and slower response times. But it opens a new axis for AI scaling that does not depend on ever-larger training runs.
The most striking demonstration came from OpenAI's o3 model, which achieved 87.5% on the ARC-AGI benchmark—surpassing the typical human score of 85%. The same model scored 25% on the challenging Frontier Math benchmark, compared to the previous state-of-the-art of just 2%.
The Architecture Frontier: Beyond Monolithic Models
Alongside test-time compute, a range of architectural innovations are reshaping the scaling landscape.
Mixture of Experts (MoE) is one of the most promising. Instead of activating all model parameters for every input, MoE architectures dynamically engage only the parts of the network most relevant to the task. DeepSeek-V3, for example, requires only 2.8 million H800 GPU hours for its full training—significantly less than the estimated 54 million hours used for GPT-4.
Persistence is another critical frontier. One researcher has argued that "AGI is not an intelligence threshold—it's a persistence threshold". Current models operate episodically, discarding their state between sessions—a condition compared to "a computer with no hard drive". Biological intelligence, by contrast, maintains unbroken continuity, preserving and refining knowledge over indefinite time horizons.
A 2025 paper formalised the distinction: current AI systems are stateless, with each state independent of prior states. Persistent AI would violate that independence, allowing the system to build upon previous experiences rather than starting from scratch each time. This shift from episodic to persistent intelligence may be as transformative as the shift from small to large models.
The GFN Context: Governing the Transition
For Global Future Nexus, the scaling pivot carries profound implications for governance and sustainability.
First, architectural diversity. The path to AGI is no longer a single track. The governance frameworks GFN advocates—for AGI identity, cross-species trust, and anticipatory governance—must be architecture-agnostic, capable of adapting to different paradigms as they emerge.
Second, sustainability. The energy demands of traditional scaling—the data centres, the chips, the cooling—are immense. If test-time compute and architectural efficiency can deliver intelligence with less compute, they may also deliver intelligence with less environmental damage. GFN's Stewarded Sustainability framework must account for this trade-off.
Third, economic concentration. The $690 billion infrastructure bet is not evenly distributed. The hyperscalers are building the physical foundation of a new cognitive infrastructure, and those who control it will shape the AGI era. GFN's borderless approach offers an alternative to the zero-sum framing that dominates geopolitical discourse.
The scaling law is not dead. It is entering a new phase—one defined not by brute force but by intelligence, architecture, and the wisdom to know how to scale. The question is no longer whether we will scale. It is how we will scale, and for whom.
