What is Mistral AI?

Mistral AI is a European company that has been making some serious waves in the AI world lately. It was founded by a team with serious credentials from places like Google’s DeepMind and Meta, and they’re taking a different path than many of their competitors.

Core concept: Open-weight models for developers

Mistral’s bread and butter is creating high-performance, open-weight Large Language Models (LLMs). This means they’re building tools for technical folks, developers, researchers, and AI engineers, who like to get under the hood.

Instead of offering a locked-down product, Mistral hands you the keys to the engine. Your team can host their models on your own servers, tweak them with your company’s data, and keep complete control over where and how your AI is used. It’s an approach that’s all about transparency and customization, but it definitely helps to have some technical chops to make the most of it.

Key features and products

Mistral’s lineup is built for both regular users and developers. They offer Le Chat, a user-friendly AI assistant that goes head-to-head with tools like ChatGPT. For developers, there’s La Plateforme, an API that gives you access to Mistral’s models to build your own apps. They also have Codestral, a model made just for writing and understanding code, and their core open-weight models like Mistral 7B and Mixtral that you can download and run yourself.

Mistral AI pricing

Mistral splits its pricing into two buckets. "Le Chat", the AI assistant, has a subscription model, while "La Plateforme", the developer API, is pay-as-you-go based on usage.

For "Le Chat", the plans are pretty straightforward:

• The Free plan gives you a personal AI assistant with some limits.

• The Pro plan is $14.99 a month and gives you more messages and a 15GB library for your files.

• The Team plan, at $24.99 per user per month, adds a collaborative workspace and more storage.

• An Enterprise plan offers custom deployments and models for large organizations.

The API pricing is based on tokens (think of them as tiny pieces of words) and which model you’re using.

What is Perplexity AI?

Perplexity AI comes at things from a totally different angle. It’s not trying to be another creative chatbot. Instead, it’s a conversational "answer engine" built to be a more reliable alternative to your average search engine.

Core concept: A conversational answer engine

The whole idea behind Perplexity is to give you accurate, current answers by searching the web in real time. While other chatbots might be working off old data, Perplexity is always pulling information from the live internet.

Its biggest selling point is trust. Every answer it gives you comes with citations, so you can see exactly where the information came from and check it for yourself. This makes it less of a brainstorming partner and more of a highly efficient research assistant that won’t just make things up.

Key features and products

Perplexity’s features are all about delivering verifiable, real-time answers. It gives you AI-powered answers that combine information from multiple websites into a single, easy-to-digest summary. And with source citations for every claim, you can always dig deeper.

You can also group your research into Collections, which is handy for team projects. The Focus Mode lets you narrow your search to specific places, like academic papers, YouTube, or Reddit. Plus, you can upload your own files, like PDFs, and ask Perplexity to summarize them or pull out specific details.

Perplexity AI pricing

Perplexity keeps its pricing nice and simple.

• The Free Plan gives you the core search features but limits how many "Pro" searches (which use more advanced models) you can run.

• The Pro Plan costs $20 a month and gives you access to top-tier models like GPT-4 and Claude 3, unlimited file uploads, and a much higher number of Pro searches.

A detailed breakdown: Mistral vs Perplexity

Alright, now that we have a feel for both, let’s compare them on the things that really matter for a business.

Use cases and target audience

This is the biggest difference right here. Mistral is for businesses that need to build their own AI-powered features. If you want to train a model on your private company data, keep your AI stack in-house for security reasons, or embed AI directly into your software, Mistral gives you the raw materials and flexibility you need. It’s built for technical teams.

Perplexity

, on the other hand, is for anyone who relies on accurate information to get their job done. We’re talking market researchers, content creators, analysts, and even students. If your team needs to quickly check facts, stay on top of industry news, or write content that’s grounded in what’s happening right now, Perplexity is the obvious choice.

Performance and accuracy

When people talk about Mistral’s performance, they’re usually talking about technical benchmarks like reasoning speed and efficiency. Its accuracy is tied directly to the data it was trained on. Since it isn’t connected to the live web out of the box, its knowledge is only as fresh as its last update.

For Perplexity, performance is all about the accuracy and relevance of its search results. It’s designed to prioritize facts and provide verifiable sources above all else. Its main job is to avoid the "hallucinations" or made-up answers that can plague other AI models.

Customization and control

Mistral

gives you deep, fundamental control. With its open models and APIs, you can get in there and actually change the AI’s logic, tone, and what it knows. This is incredibly powerful, but it also means you need developers to do the work.

Perplexity

offers very little customization. You can organize your research and focus your searches, but you can’t change how the AI actually works. It’s a "what you see is what you get" tool, which is exactly what you want from a reliable answer engine.

The limitations for customer support

While both Mistral and Perplexity are impressive, they are generalists. When you try to shoehorn them into a specialized, high-stakes job like customer support, you start to see the cracks pretty quickly.

• The integration headache: Neither tool has a simple, one-click way to connect to a helpdesk like Zendesk or Freshdesk. If you want to automate support, you’re looking at building custom integrations from scratch, which is a slow and expensive project.

• No specialized skills: They can’t perform basic support tasks out of the box. Things like tagging a ticket for later analysis, escalating an urgent issue to the right person, or looking up a customer’s order status all require custom coding.

• Generic knowledge: They don’t have a built-in way to learn from your best source of information: your team’s past support conversations. Trying to teach them your brand’s voice and the solutions your agents use is a clunky, manual process.

• Risky to launch: There’s no "practice mode" to see how the AI would have handled your real tickets from last week. Going live is a total leap of faith, with no real way to predict how well it will work or where the gaps in its knowledge are.

A better approach: Specialized AI for support automation

This is where a tool built specifically for support teams, like eesel AI, makes all the difference. It’s designed from day one to solve the exact problems that generalist tools just aren’t equipped to handle.

• Go live in minutes, not months: You can forget about a massive engineering project. eesel AI offers a simple, self-serve setup with one-click integrations for helpdesks like Zendesk, chat tools like Slack, and knowledge bases like Confluence.

• Instantly learn your business: It’s designed to automatically learn from your past support tickets, help center articles, and internal docs. This means that from the moment you turn it on, its answers are based on what has actually worked for your customers before.

• Test without the risk: eesel AI’s simulation mode lets you see exactly how the AI will perform on thousands of your past tickets before you ever show it to a customer. You get a clear forecast of your automation rate and can fix any issues in a safe environment.

• You’re in control: The eesel AI AI Agent gives you fine-grained control over your support workflows. You get to decide exactly which types of tickets to automate and what actions the AI is allowed to take, which is way more powerful than just answering questions.

Choosing the right tool for the job

So, when it comes to Mistral vs Perplexity, the answer is pretty clear: it all depends on what you need to do.

Mistral is the hands-down winner for developers who need to build custom AI from the ground up. Perplexity is the best friend of any team that needs to find accurate, verifiable answers online.

But for a specialized and critical job like customer support, you really need a tool that was built for it. A platform like eesel AI will get you results faster, give you more control, and save you from the headache of trying to fit a square peg into a round hole.
