SemiAnalysis, a respected source among AI researchers and industry professionals, has published an in-depth analysis challenging widespread concerns about the slowdown of artificial intelligence scaling.
The detailed report reveals how AI labs like OpenAI and Google Deepmind are pushing past limitations with smarter techniques, including reasoning models, synthetic data, and innovative training methods. According to SemiAnalysis, this highlights a shift in older AI growth strategies that were just based on larger training sets, proving that scaling laws remain robust and transformative.
They say that AI scaling laws remain vibrant, driven by breakthroughs in reasoning models, synthetic data, and smarter training methods and that these innovations are successfully reshaping the future of AI, proving that scaling is evolving rather than slowing.
Scaling Laws: Misconceptions and Reality
The report aims to respond to growing wave of skepticism around AI scaling laws, fueled by concerns about plateauing benchmark performance, data scarcity, and hardware constraints.
Critics argue that large language models (LLMs) are showing diminishing returns, and the industry is running out of ways to train and optimize them effectively.
SemiAnalysis highlights how leading AI labs are tackling these challenges by embracing new dimensions of scaling, such as reasoning-based training methods, innovative post-training optimization, and inference-time scaling. According to the report, these advancements are pushing AI capabilities far beyond previous limits.

Reasoning Models: Expanding the Frontier
A central focus of their findings is the rise of reasoning models like OpenAI’s o1 Pro Mode and the related new ChatGPT Pro plan for $200/month.
Built on the “Strawberry” framework, o1 Pro Mode adopts chain-of-thought reasoning, a technique that allows AI to approach problems step by step. The methodology mirrors human logic, enabling the model to excel at multi-step challenges in mathematics, coding, and complex reasoning tasks.
The report emphasizes o1 Pro Mode’s achievements on benchmarks such as the International Mathematics Olympiad, where it outperformed its predecessor, GPT-4o, by solving 83% of problems compared to GPT-4o’s 13%.
“The reality is that there are more dimensions for scaling beyond simply focusing on pre-training, which has been the sole focus of most of the part-time prognosticators. OpenAI’s o1 release has proved the utility and potential of reasoning models, opening a new unexplored dimension for scaling,” SemiAnalysis notes. “Shifting from faulty benchmarks to more challenging ones will enable better measures of progress.”
Like OpenAi’s o1 and o1 Pro models, the just unveiled Google Gemini 2.0 models build on reasoning and multimodal integration to address complex, real-world scenarios.

Synthetic Data: A Solution to the Data Wall
SemiAnalysis points out the increasing role of synthetic data in overcoming one of AI’s biggest hurdles: the so-called “data wall.” High-quality datasets are increasingly difficult to source, especially for specialized training needs. Synthetic data offers a scalable solution, enabling labs to create tailored datasets for specific tasks.
According to the authors, synthetic data isn’t just a workaround but rather a breakthrough. Techniques like rejection sampling ensure that only the most relevant and accurate synthetic outputs are used, reducing noise and improving training efficiency.

By creating these datasets in-house, labs like OpenAI and Google can bypass the constraints of real-world data while enhancing model performance in niche domains. SemiAnalysis applauds this approach:
“Synthetic data has opened a dimension where high-quality data can be generated using a controlled, beyond scalable methodology to fine-tune models over any subject matter for which there exists a will to create it.
The heavy use of synthetic data also incentivizes a push toward better models. For example, OpenAI had GPT-4 before anyone else and could use it to generate better synthetic data sets than other model providers – until other providers had a model to match. One the primary reasons that many models in Open Source and at Chinese Labs caught up so fast was that they were trained on synthetic data from GPT-4.”

Post-Training Optimization: Smarter Models, Faster
The report also highlights the growing importance of post-training optimization, where models are fine-tuned for specific tasks after their initial training. Techniques such as supervised fine-tuning (SFT) and reinforcement learning with AI feedback (RLAIF) are enabling labs to align models more closely with desired outcomes, such as improved reasoning and accuracy.
RLAIF, in particular, is increasing replacing traditional human-labeled feedback with AI-generated evaluations, significantly reducing costs and time. This iterative approach creates a feedback loop where models continuously improve their own training processes.
According to the report, post-training optimization is a critical factor in making reasoning models like o1 Pro Mode and Gemini 2.0 more reliable and versatile.
Inference-Time Scaling: AI That Thinks in Real Time
The report also points to inference-time scaling as another transformative development. This approach dynamically allocates compute resources during problem-solving, allowing models to revisit earlier steps, explore alternative solutions, and refine their outputs in real time.
Techniques such as Monte Carlo rollouts and self-consistency searches enable models to test multiple reasoning paths simultaneously, improving accuracy and adaptability. While this method demands robust computational infrastructure, it represents a significant leap forward in making AI systems more intelligent and responsive.
The SemiAnalysis report comes with a clear message: AI scaling isn’t slowing—it’s transforming. Labs like OpenAI and Google are leading this evolution by prioritizing smarter training methods, synthetic data generation, and advanced reasoning frameworks. These innovations are breaking through traditional limitations, setting the stage for a new era of AI growth.
