LLMs at the start of 2025: Breakthroughs, Challenges, and Why You Should Care

The LLM landscape in 2024 has been wild with breakthroughs, and Willison’s article does an excellent job giving a good overview of where we are in 2025. It’s a must-read if you’re curious about where things are headed.

Some key points he touches on…costs are dropping thanks to fierce competition, making LLMs more accessible than ever. At the same time, their capabilities are expanding dramatically. Multimodal functionality is here, integrating text, video, images, and even live voice and camera inputs. It’s making AI feel less like a tool and more like a partner.

But it’s not all rosy. Simon points out, that these models are getting trickier to use, and environmental concerns around large-scale training persist. Still, the use of synthetic training data and these advanced features are reshaping what’s possible.

I’d highly recommend checking it out to understand what’s happening now and what’s coming next.

O’Reilly’s latest Technology Trends for 2025 report is a must-read for anyone in our field. It highlights a significant surge in AI-related skills, with topics like prompt engineering up 456% and generative AI up 289%. Interestingly, there’s a 13% drop in interest for GPT, suggesting a shift towards foundational AI knowledge over platform-specific skills.

Additionally, data engineering skills have risen by 29%, underscoring the critical role of data in powering AI applications. However, traditional programming languages like Python and Java have seen declines, while Rust is gaining traction with a 9.6% increase.

The report also notes a plateau in cloud computing interest, with content use for major cloud providers down across all categories except Google Cloud certifications, which experienced 2.2% growth.

O’Reilly took a more educational approach to this report than some of the other year-end reports I read this year. It’s well worth the read.

The Hidden Cost of Over-Abstraction: Balancing Efficiency and Complexity in Data Engineering

An excellent post by Zakaria Hajji who delves into the pitfalls of excessive abstraction in data engineering. He makes the argument that while abstraction can streamline processes and enhance efficiency, overdoing it may lead to increased complexity, reduced performance, and a disconnect from the underlying data structures.

The piece focuses on maintaining a balance between abstraction and practical implementation. Hajji argues that understanding the foundational elements of data systems is crucial for making informed decisions and avoiding the trap of creating overly complex solutions that are difficult to manage and troubleshoot.

This post serves as a reminder to critically assess the level of abstraction applied in projects. It encourages a thoughtful approach that considers both the benefits and potential drawbacks, ensuring that systems remain efficient, understandable, and aligned with business objectives.

The article is well worth a read for the engineers-turn-managers considering how to optimize a team.

Semantic Layers and AI: Revolutionizing Data Querying with Natural Language

Our friend Cube shared a great article discussing how integrating semantic layers with AI is transforming data querying, making it more intuitive and accessible.

Semantic layers act as a bridge between raw data and business logic, providing structured definitions and metadata that AI models can interpret accurately. This integration enables users to perform complex data queries using natural language, streamlining data exploration and analysis.

For data practitioners, they make a case that this approach integration signifies a shift toward more user-friendly data interaction models. Understanding and implementing semantic layers in conjunction with AI can lead to more efficient data workflows and democratize data access across organizations.

Recognizing the Boundaries of Quantitative Analysis

A great read and an important reminder for all of us working in data. Nguyen examines the inherent constraints of relying solely on data for decision-making.

Nguyen argues that while data provides a universal language for policymakers and organizations, it often lacks the nuanced context necessary for fully informed decisions. He illustrates this with an example from the art world, where machine learning models trained on metrics like engagement hours may prioritize addictiveness over the true quality or impact of art.

The article emphasizes that data collection methods, by their nature, filter out certain qualitative aspects such as happiness, community, and beauty, elements that are challenging to quantify but essential to human experience. Nguyen cautions against an over-reliance on quantitative metrics, advocating for a more balanced approach that acknowledges the limitations of data and incorporates qualitative insights.

For data professionals, this perspective serves as a crucial reminder to consider the broader context beyond the numbers. Understanding the limitations of data can lead to more holistic and effective decision-making processes.
