Comparing Bing Chat , Open AI chat GPt and Google bard: Chatting with BOB

First half of 2023 has been exciting month in terms of further developments in the AI ecosystem, while Meta launched new Llama version. MS integrated Open AIs chat GPT capabilities into its Azure stack of services as well as power apps, flows and AI generator. Microsoft also launched Bing Chat public and Enterprise version rapidly scaling GPT 4 based chat searches to an enterprise grade tool with many additional capabilities. Google Bard which works on PaLM - 2  is also improving gradually , I decided to compare Bing , Open AI chat GPT and Bard (BOB) form an end user perspective with publicly available versions (Not Enterprise versions). For the purpose of this comparison I have ignored any open AI chat GPT plug ins which may extend its functionalities and allow it to perform some more tasks.   GUI:- While Open AI GPT has still been running on same GUI from last 6 months or so its other counterparts have not only done some improvements but also used their ecosystems to integrate their search Bots with it Open AI CHAT GPT has prompt input, output area as well as historical view. Whereas if we look at Bing Chat it has added image and voice inputs with text for prompt input . It provides latest web indexed up to date information post searching from internet and citations as well as follow up prompt suggestions related to topic. One of the key drawback of Bing chat is that its currently locked in with MS edge and doesn’t work with any other browser. Bard is also well integrated with google search. Its prompt input supports both text and voice (No image yet) but you can provide an image of video for it to analyse via URL for example you can directly give it a you tube video link and ask Bard to explain same .Once the output is provided there is option to convert response text to voice as well as share or google and provide feedback. The output of each prompt is provided in 3 draft variants and any one of those can be further explored.  Up to date information: Both Bing chat and Google Bard use indexed internet UpToDate information to provide prompt response whereas open AI has still been restricted to 2021 data making Bing and Bard immediate first choice for users to get their answers based on live information.   Citations: One of the key struggle for organizations and users developing AI use cases is to get the clarity and source of information behind the output provided and Bing and Bard has now taken next step by providing link to citations of their source information whereas in Open AI chat users are still left wondering form which exact source the information has been provided.   Custom doc training: Bing and Bard have provided easy way to provide response on custom user docs , Bing can access links to a web page or a document which Is opened in MS edge  and provide summarization , answers on those document which is also possible for Bard but same is not an off the shelf functionality with Open AI chat GPT.   Image and Speech handling: While Open AI GPT is still a text-based interface even after having a sibling Dall E available for image generation its synergies have not been used. Microsoft Bing has combined both images and text and not only it can recognize images but also use Dall-E to generate images for various prompts. Bing is also able to understand speech prompts. Google bard has also extended its functionalities to speech where it is able to understand speech prompt and also read out the outcome to users. These functionalities represent true inclusiveness for AI which will enable Bing and Bard to reach larger section of users.   speed & Temperature control: All 3 chats support temperature control helping response to be either more factual or more creative. Since Bing and Bard are actually using internet search as well they seem a bit slower then Open AI GPT which starts generating response as soon as prompt is submitted.   Summary: Overall Microsoft has leaped ahead in using its mighty ecosystem and integrating GPT4 based bing chat with its various platforms thus creating a perfect package for organizations which can be adopted rapidly without much work for their custom data training. Its key to highlight while GPT 4 has been found to be better then GPT 3.5 , recent study by UC Berkley and Stanford which compared two lates versions of GPT 4 released between March and June have raised concern about GPT 4s performance and accuracy for mathematical calculations . Google Bard has also been catching up rapidly and available for enterprise use by Google workspace. Open AI GPT has been released for commercial use with various plans and is open for enterprise use either directly or via API integration.
