The best AI for coding in 2024 (and what not to use)

I have been round expertise for lengthy sufficient that little or no excites me, and even much less surprises me. However shortly after Open AI’s ChatGPT was launched, I requested it to put in writing a WordPress plugin for my spouse’s e-commerce web site. When it did, and the plugin labored, I used to be certainly stunned.

That was the start of my deep exploration into chatbots and AI-assisted programming. Since then, I’ve subjected 10 giant machine fashions (LLMs) to 4 real-world checks.

Sadly, not all chatbots can code alike. It has been 18 months since that first take a look at, and even now, 5 of the ten LLMs I examined cannot create working plugins. 

On this article, I will present you the way every LLM carried out towards my checks. There are two chatbots I like to recommend you utilize, however they value $20/month. The free variations of the identical chatbots do effectively sufficient that you might most likely get by with out paying. However the remaining, whether or not free or paid, aren’t so nice. I will not danger my programming tasks with them or advocate that you simply do till their efficiency improves.

I’ve written loads about utilizing AIs to assist with programming. Until it is a small, easy challenge, like my spouse’s plugin, AIs cannot write whole apps or applications. However they excel at writing just a few traces and aren’t unhealthy at fixing code. 

Relatively than repeat every part I’ve written, go forward and browse this text: The way to use ChatGPT to put in writing code: What it could actually and might’t do for you.

If you wish to perceive my coding checks, why I’ve chosen them, and why they’re related to this evaluation of the ten LLMs, learn this text: How I take a look at an AI chatbot’s coding potential – and you’ll too.  

Let’s begin with a comparative take a look at how the chatbots carried out:

Subsequent, let’s take a look at every chatbot individually. I will talk about 9 chatbots, though the above chart reveals 10 LLMs. The outcomes for GPT-4 and GPT-4o are each included in ChatGPT Plus. Prepared? Let’s go.

ChatGPT Plus

Greatest total AI chatbot for coding

• Worth: $20/mo
• LLM: GPT-4o, GPT-4, GPT-3.5
• Desktop browser interface: Sure
• Devoted Mac app: Sure
• Devoted Home windows app: No
• Multi-factor authentication: Sure
• Checks handed: 4 of 4

ChatGPT Plus with GPT-4 and GPT-4o handed all my checks. One in every of my favourite options is the supply of a devoted app. Once I take a look at internet programming, I’ve my browser set on one factor, my IDE open, and the ChatGPT Mac app operating on a separate display screen.

As well as, Logitech’s Immediate Builder, which pops up utilizing a mouse button, could be arrange to make use of the upgraded GPT-4o and hook up with your OpenAI account, making it a easy thumb-tap to run a immediate, which could be very handy.

The one factor I did not like was that considered one of my GPT-4o checks resulted in a dual-choice reply, and a kind of solutions was mistaken. I would somewhat it simply gave me the right reply. Even so, a fast take a look at confirmed which reply would work. However that concern was a bit annoying. I did not have that concern in GPT-4, so for now, that is the LLM setting I exploit with ChatGPT when coding.

Perplexity Professional

Greatest AI chatbot for LLM testing

• Worth: $20/mo
• LLM: GPT-4o, Claude 3.5 Sonnet, Sonar Massive, Claude 3 Opus, Llama 3.1 405B
• Desktop browser interface: Sure
• Devoted Mac app: No
• Devoted Home windows app: No
• Multi-factor authentication: No
• Checks handed: 4 of 4

I critically thought-about itemizing Perplexity Professional as one of the best total AI chatbot for coding, however one failing stored it out of the highest slot: the way you log in. Perplexity would not use username/password or passkey, and would not have multi-factor authentication. All of the software does is e-mail you a login pin. The AI additionally would not have a separate desktop app, as ChatGPT does for Macs.

What units Perplexity other than different instruments is that it could actually run a number of LLMs. When you cannot set an LLM for a given session, you possibly can simply go into the settings and select the lively mannequin.

For programming, you may most likely need to follow GPT-4o, as a result of that aced all our checks. However it may be attention-grabbing to cross-check code throughout the completely different LLMs. For instance, when you have GPT-4o write some common expression code, you may contemplate switching to a distinct LLM to see what that LLM thinks of the generated code.

As we’ll see under, most LLMs are unreliable, so do not take the outcomes as gospel. Nonetheless, you should use the outcomes to present you extra issues to verify your authentic code. It is type of like an AI-driven code evaluation.

Simply do not forget to modify again to GPT-4o.

ChatGPT Free

Greatest free AI chatbot for coding

• Worth: Free
• LLM: GPT-4o, GPT-3.5
• Desktop browser interface: Sure
• Devoted Mac app: Sure
• Devoted Home windows app: No
• Multi-factor authentication: Sure
• Checks handed: 3 of 4 in GPT-3.5 mode

ChatGPT is obtainable to anybody totally free. Whereas each the Plus and free variations help GPT-4o, which handed all my programming checks, there are limitations when utilizing the free app.

OpenAI treats free ChatGPT customers as in the event that they’re within the low cost seats. If site visitors is excessive or the servers are busy, the free ChatGPT will solely make GPT-3.5 out there to free customers. The software will solely enable you a sure variety of queries earlier than it downgrades or shuts you off.

I’ve had a number of events when the free model of ChatGPT successfully informed me I would requested too many questions.

ChatGPT is a good software, so long as you do not thoughts getting shut down typically. Even GPT-3.5 did higher on the checks than all the opposite chatbots, and the take a look at it failed was for a reasonably obscure programming software produced by a lone programmer in Australia.

So, if funds is vital to you and you’ll wait when minimize off, go for ChatGPT free.

Perplexity Free

Greatest free AI chatbot for coding and analysis

• Worth: Free
• LLM: GPT-3.5
• Desktop browser interface: Sure
• Devoted Mac app: No
• Devoted Home windows app: No
• Multi-factor authentication: No
• Checks handed: 3 of 4

I am threading a reasonably superb needle right here, however as a result of Perplexity AI’s free model relies on GPT-3.5, the take a look at outcomes have been measurably higher than the opposite AI chatbots.

From a programming perspective, that is just about the entire story. However from a analysis and group perspective, my ZDNET colleague Steven Vaughan-Nichols prefers Perplexity over the opposite AIs.

He likes how Perplexity supplies extra full sources for analysis questions, cites its sources, organizes the replies, and gives questions for additional searches.

So if you happen to’re programming, but in addition doing different analysis, contemplate the free model of Perplexity.

Chatbots to keep away from for programming assist

I examined 9 chatbots, and 4 handed most of my checks. The opposite chatbots, together with just a few pitched as nice for programming, every solely handed considered one of my checks — and Microsoft’s Copilot did not go any.

I am mentioning them right here as a result of folks will ask, and I did take a look at them completely. Some bots do exactly superb for different work, so I will level you to their normal opinions if you happen to’re simply inquisitive about how they perform.

Meta AI

Meta AI is Fb’s general-purpose AI. As you possibly can see above, it failed three of our 4 checks. 

The AI did generate a pleasant consumer interface however with zero performance. And it did discover my annoying bug, which is a reasonably severe problem. Given the particular data required to search out the bug, I used to be stunned it choked on a easy common expression problem. However it did.

Meta Code Llama

Meta Code Llama is Fb’s AI designed particularly for coding assist. It is one thing you possibly can obtain and set up in your server. I examined it operating on a Hugging Face AI occasion.

Weirdly, though each Meta AI and Meta Code Llama choked on three of 4 of my checks, they choked on completely different issues. AIs cannot be counted on to present the identical reply twice, however this end result was a shock. We’ll see if that adjustments over time.

Claude 3.5 Sonnet

Anthropic claims the three.5 Sonnet model of its Claude AI chatbot is right for programming. After failing all however one take a look at, I am not so positive.

For those who’re not utilizing it for programming, Claude could also be a more sensible choice than the free model of ChatGPT. 

My ZDNET colleague Maria Diaz experiences that Claude can deal with uploaded information, course of extra phrases than the free model of ChatGPT, present data roughly a 12 months extra present than GPT-3.5, and entry web sites.

Gemini Superior

Gemini Superior is Google’s $20 professional model of its Gemini (previously Bard) chatbot. I anticipated the software to do higher than one out of 4. Apparently, it handed the one take a look at that each AI apart from GPT-4/4o failed — data of that pretty obscure programming language produced by one programmer in Australia.

So, if it knew that language, why could not it deal with fundamental common expressions or different first-year programming pupil issues?

Microsoft Copilot

You’d assume the corporate with the “Builders! Builders! Builders!” mantra in its DNA would have an AI that does higher on the programming checks. Microsoft produces a few of the greatest coding instruments on the planet. And but, Copilot did badly.

The one constructive factor is that Microsoft at all times learns from its errors. So, I will verify again later and see if this end result improves.  

However I like [insert name here]. Does this imply I’ve to make use of a distinct chatbot?

In all probability not. I’ve restricted my checks to day-to-day programming duties. Not one of the bots has been requested to speak like a pirate, write prose, or draw an image. In the identical method we use completely different productiveness instruments to perform particular duties, be happy to decide on the AI that helps you full the duty at hand. 

The one concern is if you happen to’re on a funds and are paying for a professional model. Then, discover the AI that does most of what you need, so you do not have to pay for too many AI add-ons.

It is solely a matter of time

The outcomes of my checks have been pretty shocking, particularly given the large investments of Microsoft and Google. However this space of innovation is bettering at warp pace, so we’ll be again with up to date checks and outcomes over time. Keep tuned.
