Meet Orca, Microsoft’s new AI model that can imitate GPT-4

In a striking breakthrough, Microsoft in partnership with OpenAI, has unveiled Orca, a compact yet formidable new AI model. This lean powerhouse, outfitted with 13 billion parameters, aims to challenge existing norms by mimicking and learning from larger, more resource-intensive models like GPT-4, all while operating with significantly less computing power. Orca heralds a new age in AI development, demonstrating that smaller, more efficient models can pack a punch that rivals their larger counterparts.

The ingenuity of Orca lies not only in its resource-efficient operation but also in its flexible nature that caters to specific tasks and allows for autonomous operation. This adaptability makes Orca a versatile tool that can meet specific needs without having to rely on large-scale data centers, a common dependency of its larger counterparts.

What sets Orca apart in the crowded AI space is its impressive performance. Outshining its predecessor, Vicuna, Orca notched a whopping 100 per cent improvement on zero-shot reasoning benchmarks, a crucial measure of an AI model's problem-solving abilities. Additionally, Orca displayed a 42 per cent speed advantage over conventional AI models on the AGIEval benchmark, further emphasising its formidable computational capabilities.

Despite its smaller size, Orca doesn’t shy away when pitted against larger AI models. Showcasing reasoning abilities that stand toe-to-toe with the popular conversational AI, ChatGPT, Orca is more than just a compact model. Its impressive academic performance further validates its intellectual prowess, a testament to its complex learning and reasoning capabilities.

Orca distinguishes itself with its ability to progressively learn. The model assimilates information from a vast array of imitation data, leveraging human-generated explanations and insights from advanced language models. This continuous learning methodology enhances Orca’s skills and capabilities over time, paving the way for its ongoing improvement.

The open-source architecture of Orca opens the door for public contributions, enhancing its capabilities and flexibility. This unique aspect not only fosters collaborative development but also positions Orca as a robust contender to privately-owned AI models such as ChatGPT.
