Meet Pi, the world’s ‘friendliest’ chatbot powered by the new Inflection-2.5 LLM

Subject: Science and tech

Section: Awareness in IT

Context:

• In less than a week, two Large Language Models (LLMs) have been launched that are closer to or even better at tasks than OpenAI’s GPT-4.

More on news:

• After Anthropic’s Claude 3 captured the attention of the AI community, Inflection AI launched its latest LLM, Inflection 2.5 which is an upgrade to its model that powers its friendly chatbot Pi personal assistant.
• Inflection AI, a California-based AI startup founded by former co-founders of DeepMind and LinkedIn, introduced Pi, their personal AI, in May 2023.

What is Inflection 2.5?

• Inflection-2.5 is an upgraded in-house model that is competitive with all the world’s leading LLMs like GPT-4 and Gemini.
• The company claims that the newly upgraded LLM comes with its signature personality and uniquely empathetic fine-tuning.
• The company claims that its latest model achieved GPT-4’s performance with only 40 per cent of the OpenAI model’s computation power for training.
• With the new upgrade, Pi has now been endowed with world-class real-time web search capabilities to ensure that users get access to high-quality and up-to-date information in real-time.

What is the Pi chatbot?

• Pi is an AI chatbot with which one can have deep and meaningful conversations.
• Pi was launched at a time when the world was marveling at OpenAI’s sensational ChatGPT. 
• While ChatGPT offered human-like responses, Pi came with a radically different vigour.
• Pi is more humane and has been promoted as a chatbot that has a personality.
• Inflection AI dubbed it as a chatbot that is “supportive, smart, and there for you anytime”.
• While ChatGPT and Gemini were mostly personal assistants that were useful at work, Pi is more like a companion to humans and is free to use.
• The chatbot comes with a voice, in six distinct voices, to choose from adding life to conversations.
• On the technical side, for training purposes, the chatbot has been shown billions of lines of text on the open web.
• Incidentally, the name Pi stands for personal intelligence and it offers infinite knowledge according to a user’s need.
• Upon its launch, Pi was powered by Inflection’s proprietary LLM Inflection-1 which was trained on thousands of NVIDIA H100 GPUs on a very large data set.
• Based on the evaluations, Inflection-1 was ranked the best model in its compute class outdoing the likes of GPT-3.5, LLaMA, and PaLM-540B on a wide range of benchmarks. In 2022, the company launched its new model Inflection-2, which was trained on 5,000 NVIDIA H100 GPUs.
• Inflection-2 outclassed Google’s flagship LLM PaLM 2 on various benchmarks including MMLU (massive multitask language understanding), TriviaQA (a realistic text-based question-answering dataset), HellaSwag& GSM8k.

How is Inflection-2.5 different?

• With the upgraded language model Inflection-2.5, the company has enhanced the emotional quotient of the Pi chatbot.
• Inflection-2.5 also outperforms its predecessor Inflection-1 on the MMLU benchmark and performs at the 85th percentile of human test-takers on the Physics GRE.
• Inflection-2.5 retains the Pi chatbot’s unique persona along with maintaining extraordinary safety standards.
• The model achieves this all the while making the chatbot a more helpful model across the board.
