ChatGPT, the OpenAI chatbot, has been available to the general public for several months now and has been a dazzling success since its release. With ChatGPT, OpenAI has shaken up the ranks of tech giants, so much so that Google was forced to unveil Bard in early February, an equivalent to ChatGPT but which differs on several levels. We take stock!

1. Data update

Bard has real-time updated data as Google’s conversational service is directly connected to the web to provide fresh, high-quality answers. Where ChatGPT is limited since it relies on a knowledge base that has not been updated since September 2021. This means that OpenAI’s chatbot is currently unable to provide responses to very recent events. ChatGPT nevertheless specifies that it can “answer hypothetical questions based on current knowledge and historical trends. » but that his answers should be taken with caution.

2. The language model

ChatGPT is based on OpenAI models and GPT-3 technology which means Generative Pre-trained Transformer 3 . Microsoft is using this technology for its new Bing, unveiled just one day after Bard.

On the other hand, Bard is powered by another language model specific to Google: LaMDA which means Language Model for Dialogue Applications. During Bard’s presentation, Google also recalled its pioneering position in the field of artificial intelligence with BERT, one of its first Transformer models, but also its technologies such as PaLM, Imagen and MusicLM.

3. Availability

While ChatGPT has been available for free to the general public since December 2022, Bard is not yet available to everyone. Google’s chat service is only open to trusted testers but is expected to roll out more widely in the coming weeks according to the firm’s official blog post.

4. Cost

In addition to its free version, OpenAI has launched a paid version: ChatGPT Plus starting at $20. This premium offer allows access to the chatbot even when demand is high (end of ChatGPT is at capacity right now), get answers faster, and get priority access to new features. On the Google side, Bard will most certainly be a free service integrated into its search engine.
