Paris – The hottest startup in Silicon Valley right now is OpenAI, the Microsoft-backed developer of ChatGPT, a much-hyped chatbot that can write a poem, college essay or even a line of software code. Tesla tycoon Elon Musk was an early investor in OpenAI and Microsoft is reported to be in talks to up an initial investment of between $1 billion and $10 billion in a goal to challenge Google's world-dominating search engine. If agreed, the cash injection by the Windows-maker would value OpenAI at a whopping $29 billion, making it a rare tech-world success at a time when major players such as Amazon, Meta and Twitter are cutting costs and laying off staff.

On Wednesday the Chartr office party was in full swing, but instead of heading for drinks -- as originally planned -- we found ourselves still in the office, writing increasingly funny prompts into ChatGPT, a chatbot from OpenAI. Built on the architecture of GPT-3, with some 175 billion parameters, the key innovation of ChatGPT relative to other AI breakthroughs is that it's super easy to interact with. "Tell me a joke", "write a recipe for pecan pie in the style of a pirate", "explain long division to a ten-year-old"... ChatGPT has a -- pretty convincing -- response for all. That functionality has gone viral, with OpenAI reporting that ChatGPT had hit 1 million users in just 5 days. Searches for ChatGPT rocketed, surpassing those for "lensa", another AI app making waves this week, but ChatGPT is undoubtedly the much, much bigger story.

This report describes our PromptShots submissions to a shared task on Evaluating the Rationales of Amateur Investors (ERAI). We participated in both pairwise comparison and unsupervised ranking tasks. For pairwise comparison, we employed instruction-based models based on T5-small and OpenAI InstructGPT language models. Surprisingly, we observed OpenAI InstructGPT language model few-shot trained on Chinese data works best in our submissions, ranking 3rd on the maximal loss (ML) pairwise accuracy. This model works better than training on the Google translated English data by a large margin, where the English few-shot trained InstructGPT model even performs worse than an instruction-based T5-small model finetuned on the English data. However, all instruction-based submissions do not perform well on the maximal potential profit (MPP) pairwise accuracy where there are more data and learning signals. The Chinese few-shot trained InstructGPT model still performs best in our setting. For unsupervised ranking, we utilized many language models, including many financial-specific ones, and Bayesian lexicons unsupervised-learned on both Chinese and English words using a method-of-moments estimator. All our submissions rank best in the MPP ranking, from 1st to 3rd. However, they all do not perform well for ML scoring. Therefore, both MPP and ML scores need different treatments since we treated MPP and ML using the same formula. Our only difference is the treatment of market sentiment lexicons.

ChatGPT is currently one of the leading topics of discussion on the internet. The artificial intelligence application is being utilized to answer questions, write reports, and also formulate software codes. Now, according to a report by Semafor, Microsoft Corp is discussing the possibility of acquiring OpenAI, the parent company of ChatGPT. The tech-industry giant is ready to pay upwards of $10 billion for the acquisition. JUST IN: Microsoft $MSFT in talks to acquire a 49% stake worth $10 billion in ChatGPT owner OpenAI.

DALL-E is a Generative Pre-trained Transformer (GPT) model developed by OpenAI that can generate images from textual descriptions.

"Microsoft is clearly being aggressive on this front and not going to be left behind on what could be a potential game-changing AI investment," said analyst Dan Ives of Wedbush Securities. Before the release of ChatGPT, OpenAI had wowed tech geeks with Dall-E 2, a software that creates digital images with a simple instruction.

OpenAI – one of the world's leading artificial intelligence research laboratories – released the text generator ChatGPT and the image generator DALL-E 2. While both programmes represent monumental leaps in natural language processing and image generation, they've also been met with apprehension. Some critics have eulogised the college essay, while others have even proclaimed the death of art. But to what extent does this technology really interfere with creativity? After all, for the technology to generate an image or essay, a human still has to describe the task to be completed. The better that description – the more accurate, the more detailed – the better the results. After a result is generated, some further human tweaking and feedback may be needed – touching up the art, editing the text or asking the technology to create a new draft in response to revised specifications.

Personally, I am not a big fan of Wikipedia. When I was studying vector mathematics for my Masters of Machine Learning degree I tried to use Wikipedia to understand some of the key concepts. It was like walking into a buzzsaw. My head certainly felt like it had been split open. When the first Encyclopaedia Brittanica was written, it was designed for lay people to look up and understand topics they otherwise wouldn't be able to access.

OpenAI is aware of the issue and plans to address it by watermarking all ChatGPT-generated text. OpenAI guest researcher Scott Aaronson said it would work using a "cryptographic pseudorandom function," where only OpenAI could access the key. So for any text that GPT generates, there would be a hidden signal in its choices of words, which only OpenAI can prove later that it came from GPT. So when this is released, ChatGPT will continue to generate text that looks random to the public, but OpenAI will be able to uncover a watermark with the secret key.
