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?
They really won't, though; Microsoft just does this kind of thing, over and over and over. Before everything was named "365", it was all "One", before that it was "Live"... 20 years ago, everything was called ".NET" whether it had anything to do with the Internet or not. Back in the '90s they went crazy for a while calling everything "Active".
So Microsoft isn't bringing copilot to all these applications? It's just bringing a copilot label to them? So glad I don't use this garbage at home.
If a large company has bought into "Co-Pilot", they want it all right? Or not, but let's not make carving anything out easy.
Just a thought.
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

Completely impossible. The search is bad to begin with, but it explicitly ignores anything that isn't a-9.
You mean Microsoft Job Copilot 365?
Nadella might have fixed a few things, but Microsoft still have massive room for improvement in many areas.
There is no tech giant that is more vulnerable than Microsoft is at this moment.
Most document originations will begin out of or adjacent to of LLM sessions in the near future, as everything will blur in terms of collaborating with AI agents. Microsoft has no footing (or worse, their position is terrible courtesy of copilot) and is vulnerable to death by inflection point. Windows 11 is garbage and Google + Linux may finally be coming for their desktop (no different than what AMD has managed in unwinding the former Intel monopoly in PCs).
Someone should be charging at them with a new take on Office, right now. This is where you slice them in half. Take down Office and take down Windows. They're so stupid at present that they've opened the gates to Office being destroyed, which has been their moat for 30 years.
Seriously, how?
There was also "Active" before that, but .NET was next level crazy...
Office.com is now "Welcome to Microsoft 365 Copilot"
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.
Leaving Microsoft’s ecosystem a few years ago has been a great productivity boost, saved quite a bit of cash, and dramatically reduced my frustration.
GitHub Copilot is a service, you can buy subscription from here https://github.com/features/copilot.

This absolutely sucks, especially since tool calling uses tokens really really fast sometimes. Feels like a not-so-gentle nudge to using their 'official' tooling (read: vscode); even though there was a recent announcement about how GHCP works with opencode: https://github.blog/changelog/2026-01-16-github-copilot-now-...
No mention of it being severely gimped by the context limit in that press release, of course (tbf, why would they lol).
However, if you go back to aider, 128K tokens is a lot, same with web chat... not a total killer, but I wouldn't spend my money on that particular service with there being better options!

What an absolute mess.
The execs buying Microsoft products are presumed to be as clueless as the execs naming Microsoft products.
AI really should be a freaking feature, not the identity of their products. What MS is doing now is like renaming Photoshop to Photoshop Neural Filter.
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.
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.
For some reason, people have great difficulty with defensive trust. Charlie Brown, Sally.
Microsoft is very explicit in detailing how the data stays on device and goes to great lengths to detail exactly how it works to keep data private, as well as having a lot of sensible exceptions (e.g., disabled for incognito web browsing sessions) and a high degree of control (users can disable it per app).
On top of all this it’s 100% optional and all of Microsoft’s AI features have global on/off switches.
My default everyday model is still Gemimi 3 in AI Studio, even for programming related problems. But for agentic work Antigravity felt very early-stages beta-ware when I tried it.
I will say that at least Gemimi 3 is usually able to converge on a correct solution after a few iterations. I tried Grok for a medium complexity task and it quickly got stuck trying to change minor details without being able to get itself out.
Do you have any advice on how to use Antigravity more effectively? I'm open to trying it again.
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.
[0] based on user Thumbs up/Thumbs down voting
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?
It's on the top of most leaderboards on lmarena.ai
Both Claude and ChatGPT were unbearable, not primarily because of lack of technical abilities but because of their conversational tone. Obviously, it's pointless to take things personally with LLMs but they were so passive-aggressive and sometimes maliciously compliant that they started to get to me even though I was conscious of it and know very well how LLMs work. If they had been new hires, I had fired both of them within 2 weeks. In contrast, Gemini Pro just "talks" normally, task-oriented and brief. It also doesn't reply with files that contain changes in completely unrelated places (including changing comments somewhere), which is the worst such a tool could possibly do.
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 reminds me of this [0] Dilbert comic, but heh.
Can anyone else share what their workflow with CC looks like? Even if I never end up switching I'd like to at least feel like I gave it a good shot and made a choice based on that, but right now I just feel like I'm doing something wrong.
I got really good at reviewing code efficiently from my time at Google and others, which helps a lot. I'm sure my personal career experience influences a lot how I'm using it.
FWIW, I use Codex CLI, but I assume my flow would be the same with Claude Code.
In essence, this is pretty much how you'd run a group of juniors - you'd sit on slack and jira diving up work and doing code reviews.
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.
meanwhile ms and github, is waiting for any breadcrumb that chatgpt leave with
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.
It's truly more capable but still not capable enough that Im comfortable blindly trusting the output.
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)
It simply didn’t work. I complained about it and was eventually hauled into a room with some MS PMs who told me in no uncertain terms that indeed, Biztalk didn’t work and it was essentially garbage that no one, including us, should ever use. Just pretend you’re doing something and when the week is up, go home. Tell everyone you’ve integrated with Biztalk. It won’t matter.
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.
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.
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.
Well, that might explain why all their products are unusable lately.
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
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.
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.
That was using the Claude Sonnet 4.5 model, I wonder if using the Opus 4.5 model would have managed to avoid that.

Plus: you can use Kimi 2.5 with Crush soon
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)
Microsoft lost its way with Windows Phone, Zune, Xbox360 RRoD, and Kinect. They haven’t had relevance outside of Windows (Desktop) in the home for years. With the sole exception being Xbox.
They have pockets of excellence. Where great engineers are doing great work. But outside those little pockets, no one knows.
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.
One of the many reasons why it's such a bad practice (overly verbose solutions id another one of course)
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.1. Classic Coding (Traditional Development) In the classic model, developers are the primary authors of every line.
Production Volume: A senior developer typically writes between 10,000 and 20,000 lines of code (LOC) per year.
Workflow: Manual logic construction, syntax memorization, and human-led debugging using tools like VS Code or JetBrains IDEs.
Focus: Writing the implementation details. Success is measured by the quality and maintainability of the hand-written code.
2. AI-Supported Coding (The Modern Workflow)
AI tools like GitHub Copilot and Cursor act as a "pair programmer," shifting the human role to a reviewer and architect. Production Volume: Developers using full AI integration have seen a 14x increase in code output (e.g., from ~24k lines to over 810k lines in a single year).
Work Distribution: Major tech leaders like AWS report that AI now generates up to 75% of their production code.
The New Bottleneck: Developers now spend roughly 70% of their time reviewing AI-generated code rather than writing it.
I think realistic 5x to 10x is possible. 50.000 - 200.000 LOC per YEAR !!!! Would it be good code? We will see.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.
This will lead to so much enshitification.
they're fucked
Take some arbitrary scaler and turn it into a mediocre metric, for some moronic target.
