These are really great results!!

Today we are rolling out an experimental Gemini Embedding model for developers with:

– SOTA performance on MTEB (Multilingual)
- Input context length of (3K --> 8K) tokens
– Output 3K dimensions
– Support for over (50 --> 100) languages

More details in 🧵

Can long-context models replace retrievers, RAG & SQL? We evaluate them on smaller-scale versions of these tasks and compare them to specialized models in same settings. We found *prompting* LLM perform surprisingly well, generalizing across text, multimodal & other settings!
Can long-context language models (LCLMs) subsume retrieval, RAG, SQL, and more?

Introducing LOFT: a benchmark stress-testing LCLMs on million-token tasks like retrieval, RAG, and SQL. Surprisingly, LCLMs rival specialized models trained for these tasks!

Instruct-Imagen is a fun project that I have learned a lot on the power of multimodal instruction tuning for image generation. When @Hexiang_Hu showed me some of the results, I was very surprised to see the generalization ability with such a simple model design!

Google released Instruct-Imagen 🎉

Instruct-Imagen matches or surpasses prior task-specific models in-domain and demonstrates promising generalization to unseen and more complex tasks according to human evaluation.

🎉 Gemini 1.0 is officially out! 🎉 Thrilled to have played a small part in this incredible project. The learning has been immense, and I continue to learn new things everyday. Onwards and upwards!

I’m very excited to share our work on Gemini today! Gemini is a family of multimodal models that demonstrate really strong capabilities across the image, audio, video, and text domains. Our most-capable model, Gemini Ultra, advances the state of the art in 30 of 32 benchmarks, including 10 of 12 popular text and reasoning benchmarks, 9 of 9 image understanding benchmarks, 6 of 6 video understanding benchmarks, and 5 of 5 speech recognition and speech translation benchmarks. Gemini Ultra is the first model to achieve human-expert performance on MMLU across 57 subjects with a score above 90%. It also achieves a new state-of-the-art score of 62.4% on the new MMMU multimodal reasoning benchmark, outperforming the previous best model by more than 5 percentage points.

Gemini was built by an awesome team of people from @GoogleDeepMind, @GoogleResearch, and elsewhere at @Google, and is one of the largest science and engineering efforts we’ve ever undertaken. As one of the two overall technical leads of the Gemini effort, along with my colleague @OriolVinyalsML, I am incredibly proud of the whole team, and we’re so excited to be sharing our work with you today!

There’s quite a lot of different material about Gemini available, starting with:

60-page technical report authored by th Gemini Team: deepmind.google/gemini/gemini_…

In this thread, I’ll walk you through some of the highlights.
