Google has unveiled its latest AI model, Gemini 1.5, which features what the company calls an “experimental” one million token context window.

The new capability allows Gemini 1.5 to process extremely long text passages – up to one million characters – to understand context and meaning. This dwarfs previous AI systems like Claude 2.1 and GPT-4 Turbo, which max out at 200,000 and 128,000 tokens respectively:

“Gemini 1.5 Pro achieves near-perfect recall on long-context retrieval tasks across modalities, improves the state-of-the-art in long-document QA, long-video QA and long-context ASR, and matches or surpasses Gemini 1.0 Ultra’s state-of-the-art performance across a broad set of benchmarks,” said Google researchers in a technical paper (PDF).

The latest model from Google gains its effectiveness from its avant-garde Mixture-of-Experts (MoE) design.

“Instead of operating as a big, single neural network like traditional Transformers, MoE models split into smaller ‘expert’ neural networks,” said Demis Hassabis, the honcho of Google DeepMind.

“The MoE models are designed to activate only the pertinent expert pathways in its neural network, based on the kind of input provided. This specialization intensifies the efficiency of the model greatly.”

The prowess of the 1M token context window was highlighted by Google using Gemini 1.5. The model was able to consume the entire 326,914-token Apollo 11 flight manuscript and then accurately responded to precise queries about it. It also concisely highlighted crucial details from a 684,000-token silent movie as instructed.

Google is initially providing developers and enterprises free access to a limited Gemini 1.5 preview with a one million token context window. A 128,000 token general release for the public will come later, along with pricing details.

In December, we launched Gemini 1.0 Pro. Today, we’re introducing Gemini 1.5 Pro! 🚀

For now, the one million token capability remains experimental. But if it lives up to its early promise, Gemini 1.5 could set a new standard for AI’s ability to understand complex, real-world text.
