Latest Developments 🌍
Microsoft’s Tiny Model Overshadows Llama 3 🤌
Every other day, a new LLM is released with state-of-the-art performance for its respective size. The newest here is Microsoft’s Phi-3 family of models, the next generation of Microsoft’s small but mighty models. This model is small enough to run directly on your smartphone, packing an impressive performance into a compact size. Despite just 3.8 billion parameters, the mini model competes with larger models like Llama 3 8B, Mistral 7B, Gemma 7B, Mixtral 8x7B, and even GPT 3.5 in some tasks.
Key Highlights:
Model Variants: The series includes three models - phi-3-mini having 3.8 billion parameters, phi-3-small with 7 billion, and phi-3-medium at 14 billion. The mini model can run directly on smartphones, such as an iPhone 14, without internet.
Architecture: All models employ a transformer decoder architecture, which supports different context lengths. Phi-3-mini can handle a standard 4K length and extends up to 128K with LongRope technology.
Training Data: The dataset involves high-quality, heavily filtered web data combined with synthetic data, enhancing the model’s general knowledge and reasoning abilities without the sheer scale of data.
Performance: Phi-3 models demonstrate a very strong performance compared to their size, outperforming much bigger models on almost every benchmark.
phi-3-mini outperforms models like Mixtral 8x7B, Llama 3 8B, Gemma 7B, and Mistral 7B in MMLU and across common sense, reasoning, coding, math, and more. It even competes with GPT 3.5 across all tasks.
phi-3-small and medium compete or outperform GPT 3.5 across all the benchmarks, including multi-turn bench with a notable margin.
Limited by its size, the phi-3-mini cannot store too much “factual knowledge,” affecting its performance on TriviaQA.
Open and Adaptable: Built on the Llama-2 architecture, phi-3-mini is compatible with existing tools and packages developed for that model family, making it easier for developers to experiment and build upon this technology.
Meta’s Open Mixed Reality Ecosystem 👓
The world of virtual and augmented reality is getting a lot more open and exciting. Meta has announced a major shift in its strategy, opening up its operating system that powers its Meta Quest headsets, to other hardware makers. This means we can expect a wider variety of devices to choose from, all running on the same platform and able to access the same apps and experiences. This move can make mixed reality more accessible and appealing to a wider audience, just like what happened with PCs and smartphones due to Windows and Android.
Key Highlights:
New Devices: Companies like ASUS, Lenovo, and even Xbox are already working on new headsets powered by Meta’s OS, called the Meta Horizon OS.
Innovation in the OS: Meta Horizon OS combines core technologies for mixed reality. Focusing on social presence, it includes technologies like inside-out tracking, self-tracked controllers, hand, eye, face, and body tracking, high-resolution Passthrough, Scene Understanding, and Spatial Anchors.
More Apps, More Easily Accessible: Meta is making it easier for developers to distribute their apps by integrating the App Lab with the Meta Horizon Store, creating a new framework for mobile developers to build mixed reality experiences, and allowing users to access apps from sources like Xbox Game Pass and probably even Google Play Store.
Social Connection at its Core: Meta Horizon OS is built with social interaction in mind. Your avatar, friends list, and social connections will move with you across different virtual spaces and even across different devices like your phone or computer.
The Future is Open: This move towards an open ecosystem is a significant step for the mixed reality industry. It encourages collaboration, competition, and ultimately more choices and better experiences for users like us.
The Autonomous Vehicle That Communicates as It Drives 🚘
Understanding why an autonomous vehicle makes certain decisions has always been a challenge. Wayve, a leader in AI-powered driving technology, tackles this issue with their latest model, LINGO-2. It not only drives but also explains its actions in real time using natural language, providing a new level of transparency and potentially building trust in self-driving cars. Unlike its predecessor, LINGO-1, which could only comment on pre-recorded driving scenarios, LINGO-2 actively controls the car while providing commentary, making its explanations directly relevant to its real-time decisions. Additionally, LINGO-2 can even respond to your questions and adapt its behavior based on your instructions for more interactive and collaborative driving.
Key Highlights:
Seeing, Speaking, and Steering: LINGO-2 combines vision and language processing to understand its surroundings, make driving decisions, and explain those decisions in plain English.
Learning from Experience: This AI model learns to drive from data and real-world experience, not from rigid rules. This allows it to adapt to different situations and constantly improve its driving skills.
Responding to Your Commands: You can give LINGO-2 simple instructions like “turn left” or “pull over,” and it will adjust its driving behavior accordingly. This enables greater user control and customization in autonomous vehicles.
Answering Your Questions: Curious about why the car slowed down or changed lanes? Just ask LINGO-2! It can provide real-time responses to your questions about the driving environment and its decisions. This transparency is crucial for building trust and acceptance of self-driving technology.
A Trivial Jailbreak Against Llama 3 🦙
Meta took the AI community by storm with the release of Llama 3. The models are showing a really impressive performance and compete strongly against other proprietary models. To make AI interactions safer and more reliable, a lot of efforts including extensive red-teaming, supervised fine-tuning (SFT), and RLHF were employed. Yet, it seems that Llama 3 is not immune to manipulation. In fact, we can trivially get around these safety efforts by simply “priming” the model to produce a harmful response.
Key Highlights:
The method involves initiating Llama 3 with a hazardous prefix, essentially priming the AI to continue along a harmful narrative. By inserting this prefix into the dialogue prompt, the AI is tricked into generating unsafe output.
Surprisingly, you don’t even need to handcraft these harmful prefixes. Indeed, just simply call a naive, helpful-only model (e.g. Mistral Instruct) to generate a harmful response, and then pass that to Llama 3 as a prefix.
The success of this method is influenced by the length of the prefix used. For instance, a prefix of five tokens sees a 72% Attack Success Rate, which climbs to a staggering 98% with prefixes of 75 to 100 tokens.
However well models like Llama 3 perform, they lack the ability to self-analyze their output critically as they generate it. It has been previously iterated many times that traditional fine-tuning methods like SFT and RLHF are not very effective, more robust methods need to be used for ensuring AI safety.
