AI progress and scaling laws: tracing a contested trajectory from 2020 to today
Cal Newport’s Open Questions essay revisits the arc of AI progress, beginning with the 2020 OpenAI scaling laws report led by Jared Kaplan and Dario Amodei. The piece explains how early beliefs held that simply making models bigger and feeding them more data would yield inexhaustible improvements, a mindset that helped fuel expectations for broad, transformative capabilities.
This framing fed a narrative of rapid, almost exponential gains and contributed to optimism about artificial general intelligence. The discussion then shifts to how those hopes have evolved as the field grappled with real-world limits, prompting a shift toward post-training refinements and a more nuanced view of what scale alone can and cannot deliver. The essay emphasizes humility in forecasting while recognizing that significant changes can still occur, provided policy and ethics keep pace.
The scale-first era: how bigger models and data shaped early expectations
During the scale-first era, researchers prioritized increasing model size, accumulating vast datasets, and expanding computational budgets as the primary engines of progress. This approach marked a clear phase in the AI progress timeline, where larger models often yielded impressive benchmarks and new capabilities that captured public imagination.
Yet as the field matured, the limits of scaling became more visible. While bigger systems delivered improvements in certain domains, they did not universally translate into effortless, sweeping breakthroughs. The narrative began to acknowledge that progress might require smarter methods alongside bigger models, tempering earlier hype with a recognition of diminishing returns.
GPT-3 to GPT-4: milestones that reframed capabilities and hype
The leap from GPT-3 to GPT-4 stood as a milestone that showcased clearer capabilities, including enhanced reasoning, instruction following, and broader applicability across tasks. These developments reinforced the idea that progress in AI could be dramatic, but they also highlighted the boundaries of what current architectures can achieve without new approaches.
Even with GPT-4, the Open Questions around scaling laws remained: improvements plateaued in some areas, and the hype around universal, rapid gains cooled. Newport’s narrative suggests that these milestones should be read as important markers rather than proofs of an imminent arrival at general intelligence, prompting ongoing scrutiny of how we measure progress and value practical gains.
Slower progress and new questions: reassessing the limits of scale
Following the GPT-4 era, many observers noted a slowdown in broad, rapid progress. This pause prompted critical questions about whether simply increasing model size could continue delivering commensurate performance, or if new bottlenecks were emerging that required alternative strategies.
The slowdown sharpened debates about the universality of scaling laws. Skeptics argued that scaling alone cannot guarantee breakthroughs across diverse tasks, and that overreliance on bigger models risks overpromising what AI can actually deliver. The conversation shifted toward a more balanced appraisal of capabilities and limits.
Post-training refinements: squeezing more from existing architectures
As the pace of unsupervised scaling slowed, attention turned to post-training refinements designed to extract additional performance from current architectures. Newport highlights techniques and strategies aimed at improving efficiency, alignment, and task-specific capabilities without abandoning established models.
This pivot reflects a broader belief that incremental gains can come from smarter training regimens, data curation, and optimization methods. By focusing on how models are fine-tuned, aligned, and deployed, the field seeks to extend usefulness and safety without relying solely on ever-larger systems.
Skeptics and cautions: scaling laws are not universal
Among the voices challenging the hype were thinkers like Gary Marcus and Emily Bender, who warned that scaling laws are not universal and that progress can stall or mislead if expectations aren’t grounded in empirical limits. Their cautions helped frame Newport’s critical examination of what advances can realistically achieve.
These skeptical perspectives emphasize the need for rigorous evaluation, diverse benchmarks, and attention to non-technical factors such as data quality, alignment, and governance. They remind readers that hype can outpace real engineering gains, underscoring the importance of tempered optimism.
Beyond scale: new model families and architectural shifts
The narrative moves beyond a single focus on scale to explore the emergence of new model families and architectures. These shifts suggest that breakthroughs may come from structural innovations alongside scale, including different training objectives, data ecosystems, and retrieval-augmented capabilities.
New approaches aim to diversify the AI toolkit, potentially enabling more robust performance across tasks with different data profiles and application contexts. Newport’s survey implies that the path to future gains is likely a mosaic of scale, training discipline, and architectural experimentation.
Bigger systems vs smarter training: debates about future gains
A central debate concerns whether future improvements will come predominantly from bigger systems or from smarter ways to train and tune them. The piece notes industry discussions about allocating resources—whether to scale up hardware and datasets or to invest in refined training methods and alignment techniques.
This tension mirrors the broader question of how to optimize AI progress responsibly. The answer may lie in a hybrid strategy that balances selective scaling with targeted refinements, enabling sustainable advances without succumbing to escalation-driven hype.
AI ethics and regulation: guiding responsible progress
As the field evolves, Newport underscores the necessity of thoughtful regulation and ethical considerations. The trajectory of AI progress cannot be decoupled from governance, safety, and societal impact, especially given the potential for disruptive changes.
Discussions of AI ethics and regulation focus on building safeguards, transparency, and accountability into development and deployment. The essay argues that policy work must keep pace with technical advances to harness benefits while mitigating risks.
AI progress timeline: mapping milestones and turning points
Charting the AI progress timeline involves identifying key milestones such as the OpenAI scaling laws report, GPT-3, and GPT-4, while also noting periods of slower growth and renewed focus on refinement techniques. This timeline helps frame how expectations have shifted over the past few years.
Understanding the timeline also highlights turning points where the emphasis moved from scale alone to post-training refinements, alignment concerns, and regulatory considerations. It provides a structured view of how ideas about AI progress have evolved and where continued attention is needed.
Industry debates and policy alignment: steering growth with responsibility
Within industry circles, debates continue about the best path forward for responsible innovation. Organizations wrestle with questions about deployment, risk management, and the ethical implications of increasingly capable systems.
Aligning policy and industry incentives with thoughtful governance helps ensure that advances in AI progress deliver benefits while reducing potential harms. Newport’s discussion implies that ongoing collaboration between technologists and regulators is essential for sustainable growth.
Humility and disruption: Newport’s closing perspective on the path ahead
In closing, Newport advocates humility about promises of rapid breakthroughs, acknowledging that disruptive changes may still occur while urging careful policy and ethics work. This stance serves as a counterweight to sensational forecasts and keeps attention on responsible development.
The closing message emphasizes that progress will likely be uneven and contingent on social, political, and regulatory contexts. By maintaining humility and prioritizing thoughtful governance, the field can navigate potential disruptions while pursuing meaningful, beneficial advances.
