ISON: Efficient Data Format for LLMs
Read Full Article: ISON: Efficient Data Format for LLMs
ISON, a new data format designed to replace JSON, reduces token usage by 70%, making it ideal for large language model (LLM) context stuffing. Unlike JSON, which uses numerous brackets, quotes, and colons, ISON employs a more concise and readable structure similar to TSV, allowing LLMs to parse it without additional instructions. This format supports table-like arrays and key-value configurations, enhancing cross-table relationships and eliminating the need for escape characters. Benchmarks show ISON uses fewer tokens and achieves higher accuracy compared to JSON, making it a valuable tool for developers working with LLMs. This matters because it optimizes data handling in AI applications, improving efficiency and performance.

Modular Pipelines vs End-to-End VLMs
Read Full Article: Modular Pipelines vs End-to-End VLMs![[D] Reasoning over images and videos: modular pipelines vs end-to-end VLMs](https://www.tweakedgeek.com/wp-content/uploads/2026/01/featured-article-7835-300x171.png)
Exploring the best approach for reasoning over images and videos, the discussion contrasts modular pipelines with end-to-end Vision-Language Models (VLMs). While end-to-end VLMs show impressive capabilities, they often struggle with brittleness in complex tasks. A modular setup is proposed, where specialized vision models handle perception tasks like detection and tracking, and a Language Model (LLM) reasons over structured outputs. This approach aims to improve tasks such as event-based counting in traffic videos, tracking state changes, and grounding explanations to specific objects, while avoiding hallucinated references. The tradeoff between these methods is examined, questioning where modular pipelines excel and what reasoning tasks remain challenging for current video models. This matters because improving how machines interpret and reason over visual data can significantly enhance applications in areas like autonomous driving, surveillance, and multimedia analysis.

7900 XTX + ROCm: Llama.cpp vs vLLM Benchmarks
Read Full Article: 7900 XTX + ROCm: Llama.cpp vs vLLM Benchmarks
After a year of using the 7900 XTX with ROCm, improvements have been noted, though the experience remains less seamless compared to NVIDIA cards. A comparison of llama.cpp and vLLM benchmarks on this hardware, connected via Thunderbolt 3, reveals varying performance with different models, all fitting within VRAM to mitigate bandwidth limitations. Llama.cpp shows a range of generation speeds from 22.95 t/s to 87.09 t/s, while vLLM demonstrates speeds from 14.99 t/s to 94.19 t/s, highlighting the ongoing challenges and progress in running newer models on AMD hardware. This matters as it provides insight into the current capabilities and limitations of AMD GPUs for local machine learning tasks.

Semantic Caching for AI and LLMs
Read Full Article: Semantic Caching for AI and LLMs
Semantic caching is a technique used to enhance the efficiency of AI, large language models (LLMs), and retrieval-augmented generation (RAG) systems by storing and reusing previously computed results. Unlike traditional caching, which relies on exact matching of queries, semantic caching leverages the meaning and context of queries, enabling systems to handle similar or related queries more effectively. This approach reduces computational overhead and improves response times, making it particularly valuable in environments where quick access to information is crucial. Understanding semantic caching is essential for optimizing the performance of AI systems and ensuring they can scale to meet increasing demands.

160x Speedup in Nudity Detection with ONNX & PyTorch
Read Full Article: 160x Speedup in Nudity Detection with ONNX & PyTorchAn innovative approach to enhancing the efficiency of a nudity detection pipeline achieved a remarkable 160x speedup by utilizing a "headless" strategy with ONNX and PyTorch. The optimization involved converting the model to an ONNX format, which is more efficient for inference, and removing unnecessary components that do not contribute to the final prediction. This streamlined process not only improves performance but also reduces computational costs, making it more feasible for real-time applications. Such advancements are crucial for deploying AI models in environments where speed and resource efficiency are paramount.
