The post "Jagged AGI: o3, Gemini 2.5, and everything after" argues that focusing on benchmarks and single metrics of AI progress creates a misleading narrative of smooth, continuous improvement. Instead, AI advancement is "jagged," with models displaying surprising strengths in some areas while remaining deficient in others. The author uses Google's Gemini 2.5 and other models as examples, highlighting how they excel at certain tasks while failing dramatically at seemingly simpler ones. This uneven progress makes it difficult to accurately assess overall capability and predict future breakthroughs. The post emphasizes the importance of recognizing these jagged capabilities and focusing on robust evaluations across diverse tasks to obtain a more realistic view of AI development. It cautions against over-interpreting benchmark results and promotes a more nuanced understanding of current AI capabilities and limitations.
The author presents a "bear case" for AI progress, arguing that current excitement is overblown. They predict slower development than many anticipate, primarily due to the limitations of scaling current methods. While acknowledging potential for advancements in areas like code generation and scientific discovery, they believe truly transformative AI, like genuine language understanding or flexible robotics, remains distant. They expect incremental improvements rather than sudden breakthroughs, emphasizing the difficulty of replicating complex real-world reasoning and the possibility of hitting diminishing returns with increased compute and data. Ultimately, they anticipate AI development to be a long, arduous process, contrasting sharply with more optimistic timelines for artificial general intelligence.
HN commenters largely disagreed with the author's pessimistic predictions about AI progress. Several pointed out that the author seemed to underestimate the power of scaling, citing examples like GPT-3's emergent capabilities. Others questioned the core argument about diminishing returns, arguing that software development, unlike hardware, doesn't face the same physical limitations. Some commenters felt the author was too focused on specific benchmarks and failed to account for unpredictable breakthroughs. A few suggested the author's background in hardware might be biasing their perspective. Several commenters expressed a more general sentiment that predicting technological progress is inherently difficult and often inaccurate.
The blog post argues that GPT-4.5, despite rumors and speculation, likely isn't a drastically improved "frontier model" exceeding GPT-4's capabilities. The author bases this on observed improvements in recent GPT-4 outputs, suggesting OpenAI is continuously fine-tuning and enhancing the existing model rather than preparing a completely new architecture. These iterative improvements, alongside potential feature additions like function calling, multimodal capabilities, and extended context windows, create the impression of a new model when it's more likely a significantly refined version of GPT-4. Therefore, the anticipation of a dramatically different GPT-4.5 might be misplaced, with progress appearing more as a smooth evolution than a sudden leap.
Hacker News users discuss the blog post's assertion that GPT-4.5 isn't a significant leap. Several commenters express skepticism about the author's methodology and conclusions, questioning the reliability of comparing models based on limited and potentially cherry-picked examples. Some point out the difficulty in accurately assessing model capabilities without access to the underlying architecture and training data. Others suggest the author may be downplaying GPT-4.5's improvements to promote their own AI alignment research. A few agree with the author's general sentiment, noting that while improvements exist, they might not represent a fundamental breakthrough. The overall tone is one of cautious skepticism towards the blog post's claims.
