02HEADLINES & LAUNCHES

MICROSOFT RELEASES POWERFUL NEW PHI-3.5 MODELS, BEATING GOOGLE, OPENAI, AND MORE

Microsoft launched three new models in its Phi series: Phi-3.5-mini-instruct, Phi-3.5-MoE-instruct, and Phi-3.5-vision-instruct, each addressing different AI tasks with impressive benchmark performances. These models are open source under the MIT License and available for developers on Hugging Face. Despite their smaller size compared to some counterparts, the Phi models have achieved near-state-of-the-art results, surpassing competitors like GPT-4o and Llama in certain benchmarks.

WHAT'S REALLY GOING ON IN MACHINE LEARNING

Stephen Wolfram, the creator of Wolfram|Alpha, wrote a great exploration about different phenomena going on in machine learning models. He discovered a set of dynamics about the non-linearities in simple neural networks.

03RESEARCH & INNOVATION

EFFICIENT LANGUAGE MODEL TRAINING

Inheritune is a streamlined method for developing smaller base language models from larger ones by inheriting a few transformer blocks and training on a tiny fraction (0.1%) of the original data. This approach enabled the creation of a 1.5B parameter model using only an A6000 GPU in less than half a day, achieving results that compete well against larger models trained on significantly more data.

TIME SERIES REPRESENTATION LEARNING WITH DIFFUSION MODELS

Time Series Diffusion Embedding (TSDE) is the first diffusion-based approach for time series representation learning. TSDE segments time series data and uses dual-orthogonal Transformer encoders with a crossover mechanism to generate informative embeddings.

EFFICIENT TRITON KERNELS FOR LLM TRAINING

The Liger Kernel, released surprisingly by LinkedIn, is an efficient set of kernels for language model training. It increases throughput by 20% and decreases memory usage by almost 60% for the popular Llama models. Importantly for practitioners, it only requires 3 lines of code change and integrates with many popular modeling frameworks.

TEACHING CHAT MODELS TO SOLVE CHESS

Traditional base language models are quite good at playing chess, averaging around 1800 elo. However, chat models tend to struggle with a precipitous drop in performance. This post explores how to tune chat models like GPT-4o to play chess through a combination of prompting and fine-tuning.

DATA EXFILTRATION FROM SLACK AI VIA INDIRECT PROMPT INJECTION

A vulnerability in Slack AI was discovered where attackers can exfiltrate data from private channels they aren't members of via indirect prompt injection. It allows attackers to use public channel messages to manipulate the LLM into divulging private information, such as API keys, in query responses. This issue, alongside a phishing attack vector, persists even after Slack AI's August 14th update incorporating channel and DM files, significantly expanding the risk surface area for such exploits.
