The pace of AI advancement is truly remarkable, and this year is no exception. Google has unveiled a new generative AI called "Gemini 1.5 Pro," which boasts a groundbreaking Mixture-of-Experts (MoE) architecture. Currently only available to a limited number of users, with broader testing to come, this technology presents intriguing breakthroughs that warrant a closer look.

1. Unprecedented Context Window of 1 Million Tokens

Gemini 1.5 Pro boasts a context window that is unfathomable by existing LLMs, capable of processing up to 1 million tokens. Research has even demonstrated data ingestion of up to 10 million tokens. This represents a revolutionary breakthrough, considering that GPT-4's context window is limited to 128,000 tokens (1).

Comparison of Context Windows for Different LLMs

With such an extensive context window, Gemini 1.5 Pro can ingest an entire book at once. Currently, when creating RAG systems and referencing internal documents, chunking is necessary to accommodate the LLM's context window. However, with Gemini 1.5 Pro, this requirement is minimized, simplifying RAG development and operation. Furthermore, the model maintains high accuracy, even with such a large context window, achieving over 99% accuracy in information retrieval tests (see chart below).

2. Remarkable In-Context Learning Capabilities

The ability to process vast amounts of data is not the only noteworthy aspect of Gemini 1.5 Pro. It also excels at understanding and applying this information to various tasks. This is evident in its in-context learning capabilities, showcased in a Kalamang language translation task. The model was trained using a Kalamang grammar book and dictionary, enabling it to translate between English and Kalamang.

Gemini 1.5 Pro outperformed other models, achieving scores that rival those of human learners. This is an astonishing feat.

3. Towards Individualized Agents with Gemini 1.5 Pro

If a model can acquire translation capabilities simply by reading a grammar book, it stands to reason that it can also learn from knowledge systems in other domains and apply that knowledge to various tasks. In other words, Gemini 1.5 Pro has the potential to develop its own "frame of reference" that influences its understanding and values. The ability to incorporate a vast amount of data into its context through its extensive context window has significant implications in this regard. This is because it allows Gemini 1.5 Pro to potentially become an individualized agent with diverse perspectives in the future. The Kalamang translation experiment provides promising evidence of this potential.

Gemini 1.5 Pro is a remarkable advancement in AI technology, offering unprecedented capabilities in terms of context window size and in-context learning. "A host of improvements made across nearly the entire model stack (architecture, data, optimization and systems) allows Gemini 1.5 Pro to achieve comparable quality to Gemini 1.0 Ultra , while using significantly less training compute and being significantly more efficient to serve" according to the report(1). This is truly a testament to the rapid progress being made in the field of AI.

I am eager to experiment with Gemini 1.5 Pro once it becomes publicly available. Stay tuned for future updates!
