There is Microsoft Copilot, which replaced Bing Chat, Cortana and uses OpenAI’s GPT-4 and 5 models.
There is Github Copilot, the coding autocomplete tool.
There is Microsoft 365 Copilot, what they now call Office with built in GenAI stuff.
There is also a Copilot cli that lets you use whatever agent/model backend you want too?
Everything is Copilot. Laptops sell with Copilot buttons now.
It is not immediately clear what version of Copilot someone is talking about. 99% of my experience is with the Office and it 100% fails to do the thing it was advertised to do 2 years ago when work initially got the subscription. Point it a SharePoint/OneDrive location, a handful of excel spreadsheets and pdfs/word docs and tell it to make a PowerPoint presentation based on that information.
It cannot do this. It will spit out nonsense. You have to hold it by the hand tell it everything to do step by step to the point that making the PowerPoint presentation yourself is significantly faster because you don’t have to type out a bunch of prompts and edit it’s garbage output.
And now it’s clear they aren’t even dogfooding their own LLM products so why should anyone pay for Copilot?
Microsoft cannot and will not ever get better at naming things. It is said the universe will split open and and eldritch beast will consume the stars the day Microsoft stops using inconsistent and overlapping names for different and conflicting products.
Isn't that right .Net/dotnet
Nadella might have fixed a few things, but Microsoft still have massive room for improvement in many areas.
There was also "Active" before that, but .NET was next level crazy...
It's unbelievable how bad they failed at this. If you do the same with Claude or ChatGPT via simple web interface, they get miles ahead.
No, there is Github Copilot, the AI agent tool that also has autocomplete, and a chat UI.
I understand your point about naming, but it's always helpful to know what the products do.
When it came out, Github Copilot was an autocomplete tool. That's it. That may be what the OP was originally using. That's what I used... 2 years ago. That they change the capabilities but don't change the name, yet change names on services that don't change capabilities further illustrates the OP's point, I would say.
I do agree that conceptually there is a big difference between an editor, even with smart autocomplete, and an agentic coding tool, as typified by Claude Code and other CLI tools, where there is not necessarily any editor involved at all.
Microsoft may or may not have a "problem" with naming, but if you're going to criticize a product, it's always a good starting place to know what you're criticizing.
Github Copilot is actually a pretty good tool.
[1] Not just AI. This is true for any major software product line, and why subordinate branding exists.

What an absolute mess.
One thing that I don't know about is if they have an AI product that can work on combining unstructured and databases to give better insights on any new conversation? e.g. like say the LLM knows how to convert user queries to the domain model of tables and extract information? What companies are doing such things?
This would be something that can be deployed on-prem/ their own private cloud that is controlled by the company, because the data is quite sensitive.
Is it the context menu key? Or did they do another Ctrl+Alt+Shift+Win+L thing?
“What do we actually need to be productive?”
Which is how Anthropic pulled ahead of Microsoft, that prioritized
checks notes
Taking screenshots of every windows user’s desktop every few seconds. For productivity.
I only gave it up because it felt like a liability and, ahem, it was awkward to review screenshots and delete inopportune ones.
Attempt to build a product... Fail.
Buy someone else's product/steal someone else's product... Succeed.
I mean they fought the browser war for years, then just used Chrome.
MS's calculus was obvious - why spend insane amounts of engineering effort to make a browser engine that nobody uses - which is too bad, because if I remember correctly they were not too far behind Chrome in either perf or compatibility for a while.
I have developed decent intuition on what kinds of problems Codex, Claude, Cursor(& sub-variants), Composer etc. will or will not be able to do well across different axes of speed, correctness, architectural taste, ...
If I had to reflect on why I still don't use Gemini, it's because they were late to the party and I would now have to be intentional about spending time learning yet another set of intuitions about those models.

It's also just not as good at being self-directed and doing all of the rest of the agent-like behaviors we expect, i.e. breaking down into todolists, determining the appropriate scope of work to accomplish, proper tool calling, etc.
Codex is the best at following instructions IME. Claude is pretty good too but is a little more "creative" than codex at trying to re-interpret my prompt to get at what I "probably" meant rather than what I actually said.
I am familiar with copilot cli (using models from different providers), OpenCode doing the same, and Claude with just the \A models, but if I ask all 3 the same thing using the same \A model, I SHOULD be getting roughly the same output, modulo LLM nondeterminism, right?
GPT-5.2 sometimes does this too. Opus-4.5 is the best at understanding what you actually want, though it is ofc not perfect.
There's also all the other Copilot branded stuff which has varying use. The web based chat is OK, but I'm not sure which model powers it. Whatever it is it can be very verbose and doesn't handle images very well. The Office stuff seems to be completely useless so far.
It's interesting to think back, what did Copilot do wrong? Why didn't it become Claude Code?
It seems for one thing its ambition might have been too small. Second, it was tightly coupled to VS Code / Github. Third, a lot of dumb big org Microsoft politics / stakeholders overly focused on enterprise over developers? But what else?
It's pretty clear that Microsoft had "Everything must have Copilot" dictated from the top (or pretty close). They wanted to be all-in on AI but didn't start with any actual problems to solve. If you're an SWE or a PM or whatever and suddenly your employment/promotion/etc prospects depend on a conspicuously implemented Copilot thing, you do the best you can and implement a chat bot (and other shit) that no one asked for or wants.
I don't know Anthropic's process but it produced a tool that clearly solves a specific problem: essentially write code faster. I would guess that the solution grew organically given that the UI isn't remotely close to what you'd expect a product manager to want. We don't know how many internal false-starts there were or how many people were working on other solutions to this problem, but what emerged clearly solved that problem, and can generalize to other problems.
In other words, Microsoft seems to have focused on a technology buzzword. Anthropic let people solve their own problems and it led to an actual product. The kind that people want. The difference is like night and day.
Who knows what else might have happened in the last 12 months if C-suites were focused more on telling SWEs to be productive and less on forcing specific technology buzzwords because they were told it's the future.
I'm sure no other tech company is like this.
I think technologies like the Windows kernel and OS, the .NET framework, their numerous attempts to build a modern desktop UI framework with XAML, their dev tools, were fundamentally good at some point.
Yet they cant or wont hire people who would fix Windows, rather than just maintain it, really push for modernization, make .NET actually cool and something people want to use.
They'd rather hire folks who were taught at school that Microsoft is the devil and Linux is superior in all ways, who don't know the first thing about the MS tech stack, and would rather write React on the Macbooks (see the start menu incident), rather than touch anything made by Microsoft.
It seems somehow the internal culture allows this. I'm sure if you forced devs to use Copilot, and provided them with the tools and organizational mandate to do so, it would become good enough eventually to not have to force people to use it.
My main complaint I keep hearing about Azure (which I do not use at workr)
CC has some magic secret sauce and I'm not sure what it is.
My company pays for both too, I keep coming back to Claude all-round
This would explain the "secret sauce", if it's true. But perhaps it's not and a lot is LLM nondeterminism mixing with human confirmation bias.
Maybe Microsoft is just using it internally, to finish copying the rest of the features from Claude Code.
Much like the article states, I use Claude Code beyond just it's coding capabilities....
I'm amazed that a company that's supposedly one of the big AI stocks seemingly won't spare a single QA position for a major development tool. It really validates Claude's CLI-first approach.
I'll know better in a week. Hopefully I can get better results with the $200 a month plan.
CC is, imo, the best. The rest are largely on pair with each other. The benefit of VSCode and Antigravity is that they have the most generous limits. I ran through Cursor $20 limits in 3 days, where same tier VSCode subscription can last me 2+ weeks
Starting in October with Vscode Copilot Chat it was $150, $200, $300, $400 per month with the same usage. I thought they were just charging more per request without warning. The last couple weeks it seemed that vscode copilot was just fucking up making useless calls.
Perhaps, it wasn't a dark malicious pattern but rather incompetence that was driving up the price.
Specifically WHY they use Apple hardware is something I can only speculate on. Presumably it's easier to launch Windows on Mac than the other way around, and they would likely need to do that as .NET and its related technologies are cross platform as of 2016. But that's a complete guess on my part.
Am *NOT* a Microsoft employee, just an MVP for Developer Technnolgies.
Because Windows' UX is trash? Anyone with leverage over their employer can and should request a Mac. And in a hot market, developers/designers did have that leverage (maybe they still do) and so did get their Macs as requested.
Only office drones who don't have the leverage to ask for anything better or don't know something better exists are stuck with Windows. Everyone else will go Mac or Linux.
Which is why you see Windows becoming so shit, because none of the culprits actually use it day-to-day. Microsoft should've enforced a hard rule about dogfooding their own product back in the Windows 7 days when the OS was still usable. I'm not sure they could get away with it now without a massive revolt and/or productivity stopping dead in its tracks.
The accounts have now all gone quiet, guess they got told to quit it.
He didn't dislike it, but got himself a Macbook nonetheless at his cost.
Claude Code is fun, full of personality, many features to hack around model shortcomings, and very quick, but it should not be let anywhere near serious coding work.
Tldr: Copilot has 1% marketshare among web chatbots and 1.85% of paid M365 users bought a subscription to it.
As much as I think AI is overrated already, Copilot is pretty much the worst performing one out there from the big tech companies. Despite all the Copilot buttons in office, windows, on keyboards and even on the physical front of computers now.
We have to use it at work but it just feels like if they spent half the effort they spend on marketing on actually trying to make it do its job people might actually want to use it.
Half the time it's not even doing anything. "Please try again later" or the standard error message Microsoft uses for every possible error now: "Something went wrong". Another pet peeve of mine, those useless error messages.
Improve the workflows that would benefit "AI" algorithms, image recognition, voice control, hand writing, code completion, and so on.
No need to put buttons to chat windows all over the place.
Until MS makes sure their models get the necessary context, I don't even care to click on them.
A.I. Tool Is Going Viral. Five Ways People Are Using It

Claude Is Taking the AI World by Storm, and Even Non-Nerds Are Blown Away
https://www.wsj.com/tech/ai/anthropic-claude-code-ai-7a46460...
The tools or the models? It's getting absurdly confusing.
"Claude Code" is an interface to Claude, Cursor is an IDE (I think?! VS Code fork?), GitHub Copilot is a CLI or VS Code plugin to use with ... Claude, or GPT models, or ...
If they are using "Claude Code" that means they are using Anthropic's models - which is interesting given their huge investment in OpenAI.
But this is getting silly. People think "CoPilot" is "Microsoft's AI" which it isn't. They have OpenAI on Azure. Does Microsoft even have a fine-tuned GPT model or are they just prompting an OpenAI model for their Windows-builtins?
When you say you use CoPilot with Claude Opus people get confused. But this is what I do everyday at work.
shrug
Well, that might explain why all their products are unusable lately.
Copilot's main problem seems to be people don't know how to use it. They need to delete all their plugins except the vscode, CLI ones, and disable all models except anthropic ones.
The Claude Code reputation diff is greatly exaggerated beyond that.
If Copilot is stupid uniquely with 5.2 Codex then they should disable that instead of blaming the user (I know they aren’t, you are). But that’s not the case, it’s noticeably worse with everything. Compared to both Cursor and Claude Code.
But I guess having my computer randomly stop working because a billion dollar corporation needs to save money by using a shitty text generation algorithm to write code instead of hiring competent programmers is just the new normal now.
* all mean 'nearly all' as of course there will be exceptions.
The difference between the two is stark.
No, one researcher at Microsoft made a personal LinkedIn post that his team were using that as their 'North Star' for porting and transpiling existing C and C++ code, not writing new code, and when the internet hallucinated that he meant Windows and this meant new code, and started copypasting this as "Microsoft's goal", the post was edited and Microsoft said it isn't the company's goal.
I use LLMs all day every day, but measuring someone or something by the number of lines of code produced is still incredibly stupid, in my opinion.
They want to expand that value into engineering and so are looking for something they can measure. I haven't seen anyone answer what can be measured to make a useful improvement though. I have a good "feeling" that some people I work with are better than others, but most are not so bad that we should fire them - but I don't know how to put that into something objective.
Most models of productivity look like factories with inputs, outputs, and processes. This is just not how engineering or craftsmanship happen.
(I think it is from "Triumph of the Nerds" (1996), but I can't find the time code)
Totally agree. I see LOC as a liability metric. It amazes me that so many other people see it as an asset metric.
"Microsoft has over 100,000 software engineers working on software projects of all sizes."
So that would mean 100 000 000 000 (100 billion) lines of code per month. Frightening.
That’s 200 Windows’ worth of code every month.
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
I miss those days.Generating bilions of lines of code that is unmaintainable and buggy should easily achieve that. ;-)
> My goal is to eliminate every line of C and C++ from Microsoft by 2030. Our strategy is to combine AI and Algorithms to rewrite Microsoft’s largest codebases. Our North Star is “1 engineer, 1 month, 1 million lines of code”.
Obviously, "every line of C and C++ from Microsoft" is not contained within a single research project, nor are "Microsoft's largest codebases".
The fact that it's a "PR disaster" for a researcher to have an ambitious project at one of the biggest tech companies on the planet, or to talk up their team on LinkedIn, is unbelievably ridiculous.
Talking about rewriting Windows at a rate of 1 million lines of code per engineer per month with LLMs is absolutely going to garner negative publicity, no matter how much you spin it with words like "ambitious" (do you work in PR? it sounds like it's your calling).
Why would you continue supposing such a thing when both the employee, and the employer, have said that your suppositions are wrong?
As @mrbungie says on this thread: "They took the stupidest metric ever and made a moronic target out of it"
The fact that there are distinguished engineers at MS who think that is a reasonable goal is frightening though.
Any MBAs want to buy? For the right price I could even fix it ...
So with this level of productivity Windows could completely degrade itself and collapse in one week instead of 15 years.
they're fucked
