Direct Preference Optimization vs. RLHF (together.ai)
We're excited to announce that the Together Fine-Tuning Platform now supports Direct Preference Optimization (DPO)! This technique allows developers to align language models with human preferences creating more helpful, accurate, and tailored AI assistants. In this deep-dive blogpost, we provide details of what DPO is, how it works, when to use it and code examples. If you'd like to jump straight into code have a look at our code notebook.

Attention Wasn't All We Needed (stephendiehl.com)
There's a lot of modern transformer techniques that have been developed since the original Attention Is All You Need paper. Let's look at some of the most important ones that have been developed over the years and try to implement the basic ideas as succintly as possible. We'll use the Pytorch framework for most of the examples.

You Don't Need Re-Ranking: Understanding the Superlinked Vector Layer (superlinked.com)
When it comes to vector search, it's not just about matching words. Understanding the meaning behind them is equally important. But there are challenges. Sometimes, factors like text meaning, popularity, and recency can lead to results that aren't quite right. This is because vector search isn't always perfect at making precise matches.

KumoRFM: A Foundation Model for In-Context Learning on Relational Data (kumo.ai)
Foundation Models (FMs) have completely taken over unstructured data domains like natural language and images, delivering significant advances in performance across tasks with little to no task-specific training. Yet structured and semi-structured relational data, which represent some of the most valuable information assets, largely miss out on this AI wave.

The Annotated Kolmogorov-Arnold Network (Kan) (alexzhang13.github.io)
Deep neural networks have been the driving force of developments in AI in the last decade. However, they currently suffer from several known issues such as a lack of interpretability, scaling issues, and data inefficiency – in other words, while they are powerful, they are not a perfect solution.

µPC: Scaling Predictive Coding to 100 Layer Networks (arxiv.org)
The biological implausibility of backpropagation (BP) has motivated many alternative, brain-inspired algorithms that attempt to rely only on local information, such as predictive coding (PC) and equilibrium propagation. However, these algorithms have notoriously struggled to train very deep networks, preventing them from competing with BP in large-scale settings. Indeed, scaling PC networks (PCNs) has recently been posed as a challenge for the community (Pinchetti et al., 2024).
