==== My Other Paper Readings Are Also Over Here ====
- Last week, one of my colleagues has introduced me about Pi.AI which make me read about this Inflection-1 LLM technical memo.
- In 2022, DeepMind and LinkedIn Co-Founders Unveil New Conversational AI Startup Inflection AI. The mission is to create personal AIs for everyone. In 2023, Inflection AI has invented Inflection-1 LLM, and Pi.AI is published and freely used, which is empowered by Inflection-1.
- Yet, DeepMind co-founder Mustafa Suleyman has become the CEO of Microsoft AI recently.
Outline
- Inflection-1
- Results
1. Inflection-1 Benchmarking Results
- To offer a fair comparison amongst models of varying sizes and training methods, foundation models are segmented into those pretrained using at most the FLOPs of Google’s PaLM-540B (approximately 10x GPT-3) and those which used more.
- First compute class: Models in the former category are usually faster to serve and can be deployed more widely.
- Second compute class: Models in the latter category tend to have the highest performance.
- GPT-3.5 to the former category and GPT-4 to the latter.
Inflection-1 was trained on a large dataset using thousands of NVIDIA H100 GPUs, and is a model within the first compute class.
- For Inflection-1, results without instruction tuning or RLHF are reported.
2. Results
2.1. Overview
Inflection-1 outperforms GPT-3.5 and LLaMA-65B for the above 5 benchmarks.
2.2. Multitask Language Understanding (MMLU)
- The proposed model outperforms all models in the first compute class including both GPT-3.5 and LLaMA.
2.3. Closed Book Question Answering
Inflection-1 is significantly better at Trivia Questions.
2.4. Others
- The above results are shown in their website while the below results only shown in the technical memo.
- Similar to OpenAI GPT-4, authors do not disclose their model size as we can see in all tables.
Inflection-1 outperforms or has similar performance with first compute class LLM in most of the tasks, only underperforms second compute class LLM such as GPT-4 and PaLM 2-L.
