After all, there are some downsides. The free model can’t absolutely browse the Web, and I discovered the boundaries on utilizing superior fashions and picture technology to be extraordinarily annoying. Typically, it hallucinates and stubbornly insists it’s proper even when it’s not–belief me, it’s somewhat infuriating! Plus, entry to newer options like SearchGPT and voice mode is locked behind the paid Plus plan.

That stated, ChatGPT stays a robust and dependable software for a wide range of duties, particularly contemplating it’s free. I imagine it has set a extremely excessive commonplace for any free AI chatbot out there. 

OpenAI could use your messages and chats to coach and enhance their mannequin when utilizing ChatGPT free and Plus plan.

You possibly can see from its response how Claude’s output is significantly better when it comes to writing fashion.

I completely cherished the truth that it may well entry real-time knowledge by way of Google Search. I’m additionally an enormous fan of the “Double-check with Google” function. Once you click on on it, the chatbot highlights sourced data in inexperienced and unsourced knowledge in orange. With this, you may actually know whether or not one thing may be hallucinated or inaccurate.  This makes it top-of-the-line AI chatbot for analysis. 

Truth-checking function on Gemini

Free picture technology with Imagen was one other side I preferred. Whereas Gemini does point out utilization limits, I do not assume I ever hit them or noticed an error message.

Gemini can write, create content material, code, and do the whole lot ChatGPT does. Nevertheless, a serious downside is the dearth of help for including recordsdata for conversations. I couldn’t add recordsdata, be it phrase or CSV, for evaluation as I may with ChatGPT or Claude, which felt restrictive.

Additionally, Gemini doesn’t provide a lot in the way in which of customization for tone, fashion, or responses besides by way of prompts. I discovered this restrictive since I needed some management over how the bot responded to me.

General, it is a good ChatGPT different, albeit with some limitations.

I’ve to confess, getting began with Dialogflow wasn’t precisely intuitive. Google makes use of very particular phrases like intents (what the bot ought to do for particular queries) and entities (key particulars inside a question) to coach the AI bot, and understanding these ideas took me a while.

The UI of Dialogflow

As soon as I obtained the hold of it, although, I may see the potential. I may entry a variety of pre-built templates for AI brokers to get began rapidly. I additionally preferred that Dialogflow helps each voice and textual content interactions in a number of languages. This flexibility is a superb function, particularly for world companies.

Nevertheless, utilizing the platform wasn’t the smoothest expertise. The web site was noticeably sluggish at occasions, which made the setup really feel extra tedious than it ought to have. Additionally, higher help documentation may have made my life simpler. After some extent, I couldn’t customise the pre-built templates.

Chatting with Copilot with out signing in

A standout function for me was how Copilot shared its sources to the data on our chats. Each time it answered a query, it included hyperlinks to the sources it pulled the data from. This transparency is invaluable, particularly when it’s good to confirm the accuracy of the response or dive deeper into the small print. 

Copilot citing supply hyperlinks when sharing data

I additionally had enjoyable creating pictures, and it appeared like one of many easy-to-use free AI picture mills.  One other plus that many customers observe is the mixing with different Microsoft merchandise if in case you have Microsoft 365 subscription or Home windows. 

Creating pictures with Microsoft Copilot

By default, Microsoft makes use of your knowledge for coaching functions until you actively disable it. To their credit score, a disclaimer about this seems firstly of each new chat, so that you’re conscious of how your knowledge may be used.

The largest draw back is the boundaries on conversations without cost customers. I hardly had 4 conversations earlier than I obtained this message. 

Error message on Microsoft Copilot

Whereas it does reset after an hour, this interruption mid-chat was irritating.  Additionally, I couldn’t add any recordsdata to make use of in our dialog. For these causes, the free model is best suited to informal conversations or gentle every day duties quite than any heavy or steady use.
