Gemini, Claude, OpenAI, all have

released their own terminal-based CLI to

integrate with AI agents. And just as I

was making this video, another one

dropped. Quinn Code is the latest in

coding IDs that are appearing. I have a

few questions I want to answer in this

video, such as what's the point of

working in a terminal. Do these terminal

CLIs have AI models that perform better

than the regular Clawude or Gemini

models? Because I'm seeing a lot of

integrations. Even Cursor now integrates

clawed code straight into the ID to make

it more accessible. I've only just

gotten used to the idea of vibe coding

and having an AI chat constantly in my

coding ID and I don't know if I'm ready

to close down my coding editor and work

directly in the terminal. But according

to Reddit, I've got no choice but to be

ready. So I'm going to take a look at

Gemini CLI, Claude Code, and OpenAI's

Codeex CLI. Let's start with Gemini.

Gemini CLI is open source and available

to download on GitHub for both Windows

and Mac OS. You can run it simply with

NPX or install it globally with npm. And

if you're wondering why you should try

it, it's because it comes with a free

tier, which means that you get access to

Gemini 2.5 Pro, the biggest model with

up to 60 requests per minute and 1,000

requests per day, all for free. It's

just finished installing, so I'm going

to run it by calling Gemini in my

terminal. And here I'm going to set the

theme, log into my Google account, and

now I'm ready to start. First up, I want

to see how good Gemini CLI is at editing

some of my websites and adding some

animations on the hero sections. You

see, I have this website on Wix Studio.

And the websites on here are using a

special programming language called

Vell, which I'm not familiar with quite

yet. I could normally code right down

here in the coding terminal. But

instead, I'm going to connect this

website up to GitHub so I can run it up

in VS Code and edit it myself. In VS

Code, I've opened up the terminal called

Gemini, and I've requested it to add

some animation to the homepage. Just

like an AI chat, it goes through and

starts making these changes. But unlike

AI chat, you can run up multiple

versions of Jan Manai that can run all

in parallel in the background completing

different tasks. It's just finished

making those changes and I've pushed

them out to production. Now, if I

preview the website, it has this

animation fade in after 1 second.

Another cool thing about Gemini is that

it's already able to connect to MCP

servers. So, I'm going to connect it to

the Wix MCP server using this JSON file

here. I relaunched Gemini. It

authenticated my MCP servers and now

it's got access to make changes on my

behalf. But we're just getting started.

On Twitter, I've seen people run

multiple Geminis all concurrently, which

is insane. And since it has a huge

context window, let's see how far we can

push the limits. I'm going to ask Gemini

to create an entire financial calculator

for me to help me do budgeting from

scratch. It created a highle plan for

the project, built it on top of Nex.js,

and here it is. I'll admit that I've

seen better oneshots on things like

Lovable or Bolt new, but this isn't

playing into the strength of using a

CLI. Now that the project is running, we

can start using that huge context window

as well as multiple instances of CLIs to

start performing multiple feature

installations all at the same time.

Gemini CLI does offer a few other things

such as being able to search the web,

create diagrams, but be aware that you

might run out of credit before you know

it. Now, I want to take a look at Claude

Code, the original CLI before they were

cool. While Gemini has grown in

popularity very quickly, Claude Code has

sustained a continuous growth due to its

performance being reliable and

consistent. I'll start by installing

Claude Code. Just like with Gemini CLI,

we need to install it in terminal as a

global package that we can use. Then

you'll need some billing details. You'll

need to connect it to Anthropic API or

your paid Claude account. Getting

started with Claude code feels a lot

more structured. Its first

recommendation is to create a readme

file by running forward/initialize. And

this goes through the project using some

of your tokens in order to get a better

understanding of it and create a basic

context that allows it to understand

what the project as a whole looks like.

It's so well written that it would be

useful even to another engineer if they

were just jumping on this project for

the first time. Now, let's see how

Claude Code goes at building a financial

app similar to what Gemini did. I've got

cursor open and it's got Claude Code

integrated. I'll test out a similar

prompt to what I had earlier, which is

to build a budgeting app from scratch to

see how it compares to Gemini CLI. Since

I've used it for a couple of weeks now,

I've noticed that Claude Code does

something different than most of the

other ways that you normally use an AI,

especially when you're just using it in

chat. You see, it uses a lot of tokens,

especially when it's trying to figure

out exactly what to do. And that isn't

necessarily a bad thing because if you

have a look at how it completes tasks

with a plan and then carries them out

and tests them properly, you'll realize

why it performs so well. This budgeting

app just finished and it's now running.

Let's test it out and see what it looks

like. Visually, it looks a lot better

than the Gemini CLI version. It has more

features like adding expenses depending

on the week, month or year, as well as

how much money I would save each month

based on the budget I create. There is

one drawback when using things like

claude code or even Gemini and the fact

that there is no version control. One

thing that I do like about using chat in

cursor or in VS Code is the fact that I

have revisions as well as history and

this lets me see exactly what's changed

and approve or reject it. However, if

I'm using something like a cloud code to

do the same sorts of changes, visually

I'm not going to see the same sort of

version tracking. Though, I have figured

out a way around this. I'm using git a

lot more to commit any changes that are

made. And this way, I can also use it to

track when changes do appear from the AI

and see exactly what's changed or

discard those changes if I don't like

them. Hopefully, these coding CLI will

have something better for version

tracking in the future, but this works

for now. Cloode instances can also run

simultaneously. There's a few ways to do

this. The first is to simply open up

multiple terminals where you can create

or request different types of features

to be set up or simply ask it to. Since

Claude actually knows how to run sub

agents in parallel. You just have to

bake it into the system prompt. Though

be aware because it can use up a lot of

tokens if you're running a lot of

requests at the same time. The final

contender for an AI based CLI is the one

from OpenAI called Codeex CLI. It's also

available on GitHub and you can install

it in your terminal, but they also have

a web version that lets you interact

directly with your own GitHub repo to

make changes in parallel in a much more

user-friendly way. I want to try out the

web version first before I open up the

terminal. It connects up to my GitHub

and I'm going to open up the same

project I had earlier, which is that Wix

Studio site I was trying to configure.

It creates three initial tasks which is

to explain the codebase, check if

there's any bugs and then also go

through to see if there are any issues

that can be fixed. Once I confirm these

are now all running in parallel in the

background with their own agents

performing the task that they're meant

to. I can expand these out and it can

show me what's happening which is a

container is starting up. I can view the

log of what's happening inside of that

container. And here it's giving me

snapshots of the terminal as it's going

through and completing that task. For

the first task, it gives me a summary of

the project. Here it is on the left,

which tells me that it's a Wix Studio

site, as well as what that codebase

looks like. In terms of the other tasks,

things like locating and fixing bugs, I

can click through and see what it's

found. Here, it's identified a better

way to run this command for hiding and

showing that top menu we created

earlier. I have the option to create a

pull request here at the top right, view

it, and then push it to my repo. That's

pretty cool for a web version, but we're

looking at CLI. So let's have a look at

how the codeex version works on my own

terminal. Here I've just installed it.

Then I'll need to log into my OpenAI

account and connect my organization.

Once done, I can load up CEX by simply

calling CEX in my terminal. Here it

requests that I make sure I run it

inside of a project I'm currently

working on. I'm running it inside of a

brand new project and I'm going to ask

it to create that financial app with a

budget that I can track my finances and

see how it performs compared to Claude

and Gemini. It runs in the background

and takes about as much time as Gemini

CLI as well as Claude Code. But

unfortunately, unlike those two, it

doesn't install Nex.js. This means I

have to open up a new tab in my

terminal, actually install and run up

the project to test what it looks like.

And here it is. Visually, it doesn't

look as good as the Gemini or Claude's

version, but in terms of the

functionality, it still works the same.

Though, it doesn't have some of the

great features that Claude Code had,

such as weekly, monthly, and yearly

tracking for expenses. My final thoughts

are that Claude Code is the best. So if

there's one you're going to pick it,

definitely try that
