This blog post details the author's successful endeavor to create audiobooks from EPUB files using an open-source large language model (LLM) called Kokoro-82M. The author meticulously outlines the entire process, motivated by a desire to listen to e-books while engaged in other activities. Dissatisfied with existing commercial solutions due to cost or platform limitations, they opted for a self-made approach leveraging the power of locally-run AI.
The process begins with converting the EPUB format, which is essentially a zipped archive containing various files like HTML and CSS for text formatting and images, into a simpler, text-based format. This stripping-down of the EPUB is achieved through a Python script utilizing the ebooklib library. The script extracts the relevant text content, discarding superfluous elements like images, tables, and formatting, while also ensuring proper chapter segmentation. This streamlined text serves as the input for the LLM.
The chosen LLM, Kokoro-82M, is a relatively small language model, specifically designed for text-to-speech synthesis. Its compact size makes it suitable for execution on consumer-grade hardware, a crucial factor for the author's local deployment. The author specifically highlights the selection of Kokoro over larger, more resource-intensive models for this reason. The model is loaded and utilized through a dedicated Python script, processing the extracted text chapter by chapter. This segmented approach allows for manageable processing and prevents overwhelming the system's resources.
The actual text-to-speech generation is accomplished using the piper functionality provided within the transformers library, a popular Python framework for working with LLMs. The author provides detailed code snippets demonstrating the necessary configurations and parameters, including voice selection and output format. The resulting audio output for each chapter is saved as a separate WAV file.
Finally, these individual chapter audio files are combined into a single, cohesive audiobook. This final step involves employing the ffmpeg command-line tool, a powerful and versatile utility for multimedia processing. The author's process uses ffmpeg to concatenate the WAV files in the correct order, generating the final audiobook output, typically in the widely compatible MP3 format. The blog post concludes with a reflection on the successful implementation and the potential for future refinements, such as automated metadata tagging. The author emphasizes the accessibility and cost-effectiveness of this method, empowering users to create personalized audiobooks from their e-book collections using readily available open-source tools and relatively modest hardware.

The Medium post, "Is Traditional NLP Dead?" explores the significant impact of Large Language Models (LLMs) on the field of Natural Language Processing (NLP) and questions whether traditional NLP techniques are becoming obsolete. The author begins by acknowledging the impressive capabilities of LLMs, particularly their proficiency in generating human-quality text, translating languages, writing different kinds of creative content, and answering your questions in an informative way, even if they are open ended, challenging, or strange. This proficiency stems from their massive scale, training on vast datasets, and sophisticated architectures, allowing them to capture intricate patterns and nuances in language.
The article then delves into the core differences between LLMs and traditional NLP approaches. Traditional NLP heavily relies on explicit feature engineering, meticulously crafting rules and algorithms tailored to specific tasks. This approach demands specialized linguistic expertise and often involves a pipeline of distinct components, like tokenization, part-of-speech tagging, named entity recognition, and parsing. In contrast, LLMs leverage their immense scale and learned representations to perform these tasks implicitly, often without the need for explicit rule-based systems. This difference represents a paradigm shift, moving from meticulously engineered solutions to data-driven, emergent capabilities.
However, the author argues that declaring traditional NLP "dead" is a premature and exaggerated claim. While LLMs excel in many areas, they also possess limitations. They can be computationally expensive, require vast amounts of data for training, and sometimes struggle with tasks requiring fine-grained linguistic analysis or intricate logical reasoning. Furthermore, their reliance on statistical correlations can lead to biases and inaccuracies, and their inner workings often remain opaque, making it challenging to understand their decision-making processes. Traditional NLP techniques, with their explicit rules and transparent structures, offer advantages in these areas, particularly when explainability, control, and resource efficiency are crucial.
The author proposes that rather than replacing traditional NLP, LLMs are reshaping and augmenting the field. They can be utilized as powerful pre-trained components within traditional NLP pipelines, providing rich contextualized embeddings or performing initial stages of analysis. This hybrid approach combines the strengths of both paradigms, leveraging the scale and generality of LLMs while retaining the precision and control of traditional methods.
In conclusion, the article advocates for a nuanced perspective on the relationship between LLMs and traditional NLP. While LLMs undoubtedly represent a significant advancement, they are not a panacea. Traditional NLP techniques still hold value, especially in specific domains and applications. The future of NLP likely lies in a synergistic integration of both approaches, capitalizing on their respective strengths to build more robust, efficient, and interpretable NLP systems.

The Sakana AI blog post, "Transformer²: Self-Adaptive LLMs," introduces a novel approach to Large Language Model (LLM) architecture designed to dynamically adapt its computational resources based on the complexity of the input prompt. Traditional LLMs maintain a fixed computational budget across all inputs, processing simple and complex prompts with the same intensity. This results in computational inefficiency for simple tasks and potential inadequacy for highly complex ones. Transformer², conversely, aims to optimize resource allocation by adjusting the computational pathway based on the perceived difficulty of the input.
The core innovation lies in a two-stage process. The first stage involves a "lightweight" transformer model that acts as a router or "gatekeeper." This initial model analyzes the incoming prompt and assesses its complexity. Based on this assessment, it determines the appropriate level of computational resources needed for the second stage. This initial assessment saves computational power by quickly filtering simple queries that don't require the full might of a larger model.
The second stage consists of a series of progressively more powerful transformer models, ranging from smaller, faster models to larger, more computationally intensive ones. The "gatekeeper" model dynamically selects which of these downstream models, or even a combination thereof, will handle the prompt. Simple prompts are routed to smaller models, while complex prompts are directed to larger, more capable models, or potentially even an ensemble of models working in concert. This allows the system to allocate computational resources proportionally to the complexity of the task, optimizing for both performance and efficiency.
The blog post highlights the analogy of a car's transmission system. Just as a car uses different gears for different driving conditions, Transformer² shifts between different "gears" of computational power depending on the input's demands. This adaptive mechanism leads to significant potential advantages: improved efficiency by reducing unnecessary computation for simple tasks, enhanced performance on complex tasks by allocating sufficient resources, and overall better scalability by avoiding the limitations of fixed-size models.
Furthermore, the post emphasizes that Transformer² represents a more general computational paradigm shift. It moves away from the static, one-size-fits-all approach of traditional LLMs towards a more dynamic, adaptive system. This adaptability not only optimizes performance but also allows the system to potentially scale more effectively by incorporating increasingly powerful models into its downstream processing layers as they become available, without requiring a complete architectural overhaul. This dynamic scaling potential positions Transformer² as a promising direction for the future development of more efficient and capable LLMs.
