AI in a Font: The Future of Large Language Models

Imagine a world where artificial intelligence (AI) is not just a tool, but a font. Yes, you read that right - a font. [Søren Fuglede Jørgensen] has managed to cram a 15 million parameter large language model into a completely valid TrueType font: llama.ttf. This means that the AI will do its magic across applications - in your photo editor as well as in your text editor.

But what magic, you ask? Say you have some text, written in some non-AI-enabled font. Highlight that, and swap over to llama.ttf. The first thing it does is to change all “o” characters to “ø"s, just like [Søren]’s parents did with his name. But the real magic comes when you type a length of exclamation points. In any normal font, they’re just exclamation points, but llama.ttf replaces them with the output of the TinyStories LLM, run locally in the font. Switching back to another font reveals them to be exclamation points after all. Bønkers!

This is all made possible by the HarfBuzz font extensions library. In the name of making custom ligatures and other text shaping possible, HarfBuzz allows fonts to contain Web Assembly code and runs it in a virtual machine at rendering time. This gives font designers the flexibility to render various Unicode combinations as unique glyphs, which is useful for languages like Persian. But it can just as well turn all “o"s into “ø"s or run all exclamation points through an LLM.

Something screams mischief about running arbitrary WASM while you type, but we remind you that since PostScript, font rendering engines have been able to run code in order to help with the formatting problem. This ability was inherited by PDF, and has kept malicious PDFs in the top-10 infiltration vectors for the last fifteen years. So if you can model a CPU in PDF, why not an LLM in TTF? Or a Pokémon clone in an OpenType font?

Moveworks Copilot: The AI-Powered Reasoning Engine

Moveworks, the leading generative AI copilot for employee support, has recently been named the “Best Generative AI Platform” in the seventh annual AI Breakthrough Awards program. The Moveworks Copilot solution combines best-in-class LLMs like Llama 3, MPNet, and GPT-4 Turbo with Moveworks’ in-house ML models and proprietary LLM, MoveLM, to produce the most sophisticated AI-powered reasoning engine on the market today.

With this reasoner in place, the Moveworks Copilot provides a ChatGPT-like experience that plugs into its customers’ entire application ecosystems - unlocking the full power of their tech stacks. Employees can now use the Moveworks Copilot to find documents in Google Docs, add line items to an expense report in Concur, switch account owners in Salesforce, change their name in Workday, and more - all from chat.

The Rise of Local AI Alternatives

OpenAI’s ban on China-based developers’ access to its service is set to contribute to the growth of the Chinese artificial intelligence (AI) sector rather than hinder its progress, industry insiders and analysts said. The US firm’s ban on China-based developers would only push away its users, forcing them to pick local AI model builders, who have been vying for a bigger slice of the market.

Chinese tech firms acted swiftly to capitalize on the ban, which will take effect from July 9, by offering migration options and free tokens to lure local customers to their services. Beijing-based Zhipu AI, considered one of the country’s best hopes to compete with OpenAI, was the first to react. It announced a “special house-moving plan” to help China-based OpenAI users “easily switch to home-grown [LLMs]”, according to a post published on its official WeChat public account.
