There are some language models like DeepMind RETRO that can make use of a 1TB text collection after the model is trained. The idea is to chunk up the text and make the blocks searchable with a neural embedding index. When you ask a question to the model, it first searches for relevant information and then adds it to the prompt. The result - you can get GPT-3 quality on a 25x smaller model. That means you could have your own GPT-3. Another advantage is that you can reference the sources and the generated text is more grounded.
An open source project could make a "search-engine-language-model" and in turn make this library much more accessible.

- Vetch 4y agoThe interesting aspect of GPT-3+ is their reasoning like behavior such as Chains of thought or "step by step" generation. There's no evidence RETRO as is has sufficient capacity for the actually interesting behaviors.
- visarga 4y agoI agree, that's why I asked the authors the same question : https://twitter.com/visarga/status/1543826941052166144 https://twitter.com/visarga/status/1543826941052166144
