Transcripts
do you remember Devon that incredible
demo that we saw just a couple weeks ago
where you gave the agents a prompt and
they built out entire code bases and I
know we've seen stuff like that before
but what really set Devon apart was the
fact that it had this incredible
interface that included the terminal the
browser the code editor and all the
agent dialogue and it was really
impressive but it had one major flaw it
was completely closed source and not
more than a couple days after that demo
went viral now we have a completely open
source version of Devon called open
Devon and today I'm going to show it to
you and that's what you're looking at
right now so I'm going to show it to you
I'm going to show you how to use it and
I'm going to show you how to install it
so this is it and I already set it all
up so let me show it to you first so it
says hello I'm Devon and I asked it
write a simple calculator app with
python so it started writing a new task
here on the right side you can see the
terminal very akin to the original Devon
we have the planner over here we have a
code editor where you can actually see
all of the code and then we have the
browser over here you can select the
different models that you want to run so
right now it supports open Ai and Cloud
3 but you can easily plug in an open
source local model as well and then over
here we have the browser and you can
choose between Lang chains agent and
code act agent and to be honest I don't
actually know the difference between
these two I haven't had a chance to test
code act agent so I'm using langing
chains agent but let's continue so
starting a new task then we go over to
the the terminal and we can actually see
so command LS there it is it looks where
it's at then it's reading from the
app.py it seems there's already a file
that does this it's a calculator app and
so on and so forth and you can see all
the output here it even tested it for me
which is really nice and then after all
that which really just took a few back
and forths and it's a very simple app
build a calculator app all done what's
next on the agenda I iterated on it so
now make an HTML interface for the
calculator so starting a new task and
then it went back and forth spun up
Local Host even tested it made sure it
all worked and then it was done so all
of this was actually pretty inexpensive
tokens wise um but it was really
impressive and you can run the
calculator like this so python
calculator. piy or you can spin up a
server and here's the calculator this is
what it built for me with just that
simple prompt so you put in your number
right here put in another number I'll
say four calculate very very basic but
the point is it works now I'm back at
open Devon and I am running it on Local
Host so this is running locally I am
using gp4 although I could easily swap
out an open source model which I'll show
you in a bit now the important thing to
remember is this project has not been
around long I'm talking days so there
are still some bugs some features still
don't work but it is very usable and the
rate of progression and new features
being added is super impressive
impressive so this is the project open
Devon it has over 8 and half thousand
stars already and if you look at GitHub
trending it is the number one trending
app on GitHub so this is going to grow
quickly and if I scroll down a little
bit there's another open source version
of Devon project called DEA although I
have tried every single day to get this
working and I can't so I'm going to keep
trying as soon as I can I'll make a
tutorial video for that but I am able to
get open Devon working and it works
really well so enough talk let me show
you how to install it I ran into a bunch
of issues hopefully I will show you how
to solve all of them and most of the
issues actually have nothing to do with
Devon they have to do with python
package management and environment
management which you know is the bane of
my existence so open a visual studio
code and that's where we're going to
start click on this button to toggle the
panel and we're going to open up our
terminal and what we're going to do is I
like to put stuff on my desktop when I'm
first playing around with it so we're
going to CD to the desktop now switch
back to the open Devon GitHub repository
you're going to click this green code
button right there and we're going to
copy the GitHub repo URL now we're going
to switch back to our terminal and we're
going to type get clone and then paste
in that URL and then hit enter and
that's it we've cloned it to our desktop
next we're going to CD into open Devon
and next we're going to click this
little button right here Explorer we're
going to open folder select the desktop
and then we're going to select open
Devon and now we have the open Deon
project open in Visual Studio code all
right now that we have that going let's
spin up a new cond environment so we're
going to do condac create DN o for open
Deon python equals 3.10 and we're going
to hit enter now I already have an
environment named that because I've gone
through this once to make sure it all
works before I show it to you so you're
not going to see this but go ahead and
install it just hit enter all right once
that's done we're going to grab this
Command right here cond to activate OD
copy paste it and it should say OD right
here it may not in your terminal if your
terminal structure is a little different
but for me I show it right there so
there we go we have o activated the next
thing you're going to need is Docker and
I'm really glad that they use Docker
because it makes the entire installation
much easier and you can actually run
these code environments in a completely
dockerized environment so to check if
you have Docker you're going to type
Docker PS and I do and there it is
however when you run Docker PS you might
get Docker is not recognized and if
that's the case you need to download
docker so you're going to come to docs.
do.com sengine install and you're going
to look for the docker desktop client
that matches your operating system so
I'm on a Mac so I click right there once
you do that it'll download and
everything else is really just drag and
drop or kind of clicking through an
interface it's very very easy you don't
need to do anything in console once
you're done with that open up vs code
again and you're going to type Docker PS
and now you should see at least this top
row right here container ID etc etc so
the next thing we're going to do is pull
the docker image and again this makes
everything really easy so we're going to
type Docker pull
gc.
iops sandbox colon
v0.1 and hit enter and there we go it's
150 megabytes downloads quite quickly
extracts and we're done so that worked
perfectly okay next we need to export
our open AI API key so to start we're
going to use open AI but I'll show you
how to set up a local model towards the
end of the video so if you don't already
have an open AI account go ahead and
sign up you need a developer account
platform.
open.com ai- Keys you're going to click
create new secret key and I'm going to
type odop Devore YT so I know it's for
YouTube and I will revoke this key
before publishing this video click copy
go back and we're going to export it
just like that and then hit enter okay
now we've exported it and basically what
export it does is it saves it as an
environment variable that we can use
with this software however the better
way to do it is to actually create a EnV
file and store it there but I'll leave
that for you to do the next thing we
need to do is set our workspace
directory and so what I'm going to set
it as is export workspace Ford equals
squiggly line/ desktop slop Deon so I'm
going to keep the workspace in the open
Devon folder just to keep it all in one
place so go ahead and hit enter there
all right now we're going to going to
install the requirements and this is
where I started to run into some
problems so I may not run into it again
just because I've solved them already
but if I do I'll show it to you and even
if I don't I'll show you the problems I
had and I'll show you how I solved them
so we're going to type which python okay
and this is only because we want to make
sure that we're using the correct python
for installing with Pip so we grab the
python version we're using then we
simply paste that in type-m PIP install
dasr requirements. txt then hit enter so
one of the issues that I faced is that
this project requires rust and
specifically the dependency o Json
requires rust and I didn't have it
installed and so I had an error here so
I didn't have it this time so this is
going to be a little bit of behind the
scenes but anytime that I do a tutorial
video I go through it once without the
camera recording and I document every
step along the way and I also document
any errors or bugs that I run into so
that when I go to record I it doesn't
take me forever so I did have to install
rust and to do that I used this command
curl d-pro parentheses equals htps D-
tlsv1.2
dssf and then so on and by the way I'll
drop all these commands in a GitHub gist
just so you have them and you don't have
to try to copy them and the next thing I
had to do was restart the terminal so
keep that in mind so one other thing I
want to point out another issue that I
ran into is the o Json issue and to
First fix it I installed rust and then I
ran into another issue with o Json and
to fix that I did this pip uninstall or
Json and then I installed it again using
this longer command which basically
installs the binary version that is
specific to my Apple silicon and that
was the problem and all of these
problems might be very specific to my
machine and you might run into other
problems I recommend Consulting Ai and
it will help you just copy paste
whatever issue you're running into and
it usually will give you some pretty
good suggestions so that command is PIP
install D- noach d-- only binary colon
all colon o Json and once I did that it
finally worked and if you do restart the
terminal you need to export the open AI
API key again because as soon as you
restart the terminal all of those
temporary environment variables are
wiped that's why using the EMV file is
always better all right now that that's
all done we're going to try try to spin
up the server and hopefully it works it
uses uicorn and this is the back end so
we need the back end and the front end
working so let me show you what to do
here uicorn open de. server. listen
Colona d-port 3000 now let's see if I
run into an issue last time when I tried
to spin up the server it would just
completely freeze and so I actually had
to restart the terminal anyway so we'll
see if we have to do that here all right
so it is looking like it's hanging again
unfortunately so what we're going to do
is hit controll C to try to quit out of
here although I think it's completely
Frozen so we're going to have to hit
contrl Z and that'll force quit it and
so let's try it again and if this
doesn't work I'm going to try restarting
the terminal completely again all right
maybe I'm being a bit impatient but I
don't think it's working so I'm going to
hit oh I spoke too soon look at that so
the second time it did work maybe it's
doing some downloads in the background
I'm not sure but it did work on the
second go so we have uicorn running at
Local Host 3000 perfect
now what we're going to do is we need to
now install and spin up the front end so
we click the little plus button right
here we wait till we get our new
terminal up and running we're still in
the open Devon folder and we still have
OD cond environment running so just
verify those things now we're going to
CD into the folder called front end and
we're going to be using node to install
it an npm and if you don't have node if
you don't have npm you need to go Google
that and or use Claud or GP or something
and just get those two things installed
it should be pretty straightforward I
believe if you're using a Mac you can
even use Brew so you could do like Brew
install npm and it should work I believe
all right so there it is so that would
work so now we have npm installed all
right so now that we have node installed
let's do npm install and that's going to
install all the front-end packages now
luckily I have much fewer issues using
npm and the whole node e ecosystem and
package management with node much fewer
issues than I do with python so
hopefully you don't run into anything
okay now that we have all of the node
packages installed we are simply going
to spin up the node server now so npm
run start-- space- dport space 3001 and
then hit enter and that's it we should
be up and running now let's give it a
try so I'm going to click on this Local
Host right there actually I'm going to
hold down command then click on the
local host and there we go open Dev
it worked wonderful so it takes a few
seconds to initialize the agent and I'm
going to switch to GPT 4 over here and
there we go hello I'm open Devon what
would you like me to build so I'll say a
simple website that says hello world and
now we'll see it working a little bit
starting new task we can also click over
to the planner now I've noticed the
planner doesn't really update that often
or maybe even at all um maybe that's a
little buggy I've also found the browser
doesn't really work all that well to be
honest the terminal seems to work great
and the code editor definitely works so
I mean there is the code there's the
hello world HTML file perfectly done so
here we go it's starting up a server all
by itself and it visited Local Host 8000
so if I actually go over to the browser
it did switch and go over to Local Host
8000 so it kind of works but there's
some little bug and it doesn't work
completely yeah and if I go back to the
logs from the back end I can see that
there was an error here and it exited so
that's it it so definitely still buggy
but they're making a ton of great
progress now let me show you how to use
basically any model including a locally
run open source model so if you wanted
to use Claud you just export these
things right here so the llm API key and
then the llm model you export this and
you do that from terminal now if you did
want to use a local model you do llm
base URL and you change it to Local Host
3000 and then you can use LM Studio you
can use ol llama you can use anything
you want as long as it exposes an open
AI compatible API endpoint and you can
even select llama 2 for your embedding
model which is really cool so you could
technically get this to be completely
local if you wanted so they are truly
trying to mimic what Devon has done and
Devon is super impressive it is
definitely not the first time we've had
coding assistance it's actually far from
it but it is one of the most if not the
most polished user interface that I've
seen so I'm really excited for open
Devon I've tried this other project DEA
a bunch and I haven't gotten it to work
but open Devon works pretty darn well so
give it a try create issues on their
GitHub repository as you come across
them contribute if you're open to that
and open Devon can be something really
special that helps developers and even
non-developers be really productive at
building code if you liked this video
