You’ve probably seen the videos. A frustrated driver sits at a menu board, trying to order a simple water and a vanilla ice cream cone, only for the McDonald's AI drive thru to somehow add nine sweet teas and a random Big Mac to the screen. It was hilarious for TikTok, but a massive headache for a company trying to shave seconds off its service times.
Fast food is a game of margins and speed. When McDonald's announced it was partnering with IBM to test automated order taking (AOT), the industry held its breath. People thought this was it—the end of the "can I take your order?" era. But then, in the summer of 2024, the Golden Arches pulled the plug. They ended the global partnership with IBM, effectively pausing their AI voice dreams at over 100 test locations. It wasn't a total surrender, but it was a loud admission that talking to a computer while a diesel truck idles next to you is a lot harder than Silicon Valley promised.
The Messy Reality of Voice Recognition
Voice AI sounds easy in a lab. It’s a disaster in the wild.
Think about the environment of a typical drive-thru. You have engine noise. You have kids screaming in the backseat. You have heavy rain hitting the roof of the car or a wind gust hitting the microphone. Most importantly, you have humans who don't speak in "clean" data. We say "um," we change our minds mid-sentence, and we use regional slang that a model trained on generic American English might not grasp immediately.
When the McDonald's AI drive thru system worked, it was seamless. When it didn't? It was a disaster. There were documented cases of the AI getting confused by a nearby customer’s conversation and adding hundreds of dollars worth of chicken nuggets to an order. In one viral clip, a woman tried to order a caramel sundae, but the AI insisted on adding multiple orders of butter packets. It sounds like a comedy sketch, but for a franchise owner, that’s a bottleneck that ruins the lunch rush.
The tech simply wasn't hitting the 95% accuracy rate that most experts believe is necessary for a "human-free" experience. Honestly, if you have to have a human employee standing by to "rescue" every fifth order, you haven't actually saved any labor costs. You’ve just made the job more annoying for the person working the headset.
Why IBM and McDonald's Parted Ways
The IBM partnership wasn't just some small trial; it was a foundational bet. McDonald's actually sold its "McD Tech Labs" to IBM back in 2021. The goal was to let a tech giant do the heavy lifting while the burger experts focused on, well, burgers.
But the "sunset" of this specific partnership doesn't mean AI is dead at McDonald's. Far from it.
Chief Information Officer Brian Rice made it clear in a memo that the company still believes a voice ordering solution for the drive-thru will be part of their future. They just aren't doing it with IBM right now. Speculation is rampant that Google might be the next dance partner, especially given their existing partnership with Google Cloud for other digital infrastructure. Google’s Gemini and specialized Vertex AI models are arguably better equipped to handle the nuances of "natural language" than the older frameworks IBM was iterating on.
The Problem With Regional Accents
One thing people often overlook is the "accent wall." A system trained in a Chicago suburb might handle a Midwestern accent just fine. Put that same McDonald's AI drive thru in deep East Texas, or the middle of Glasgow, or even a heavy-traffic spot in Queens, New York, and the error rate spikes.
Language models struggle with:
- Heavy regional dialects.
- Code-switching (mixing languages).
- Non-native speakers.
- Mumbled speech from drivers leaning away from the mic.
If you can't serve 100% of your customers, you're alienating people. McDonald's is a volume business. They can't afford to lose 5% of their customers because a computer couldn't understand the word "frappe."

The Labor Shortage vs. The Tech Cost
The big "why" behind all of this is labor. It’s getting harder and more expensive to staff fast-food restaurants. AI doesn't need a 401k. It doesn't call in sick on a Saturday morning.
However, the hardware required to run high-end AI at the "edge"—meaning at the actual restaurant—is expensive. You need high-quality microphones, noise-canceling arrays, and enough processing power to ensure there isn't a five-second delay between the customer speaking and the screen updating. If the AI is too slow, the driver gets annoyed and starts repeating themselves, which confuses the AI even more. It’s a feedback loop of frustration.
Despite the IBM breakup, McDonald's isn't the only one in the game. Wendy’s has been testing "FreshAI" with Google. White Castle has worked with SoundHound. Checkers and Rally’s have been using AI for years. The difference is that McDonald's is the gold standard. If they can't make it work at scale, everyone else starts questioning their own investments.
It's Not Just About Voice
We shouldn't think of the McDonald's AI drive thru as just a robot voice. The AI is also working behind the scenes.
Have you noticed how the menu boards change based on the time of day, the weather, or even what’s currently trending? That’s AI. If it’s 95 degrees out, the board might prioritize McFlurries and iced coffee. If the kitchen is backed up on Quarter Pounders, the AI might subtly suggest McNuggets instead to keep the line moving. This "predictive ordering" is much more successful and less "glitchy" than the voice recognition part. It’s invisible, so people don't make TikToks about it, but it's likely doing more for the bottom line than the voice bot ever did.
There is also the matter of license plate recognition. Some chains are testing AI that recognizes a returning customer’s car (if they’ve opted in via an app) and asks, "Do you want your usual Big Mac meal today?" It’s a bit Big Brother, but for a certain type of customer, it’s the ultimate convenience.
What's Next for the Golden Arches?
The IBM test ended in July 2024. Since then, the company has been in a "re-evaluation" phase. They are looking for a solution that can handle the sheer scale of 14,000+ U.S. locations.
Don't expect the AI to stay away for long. The push toward automation is inevitable because the math demands it. We will likely see a more integrated approach where the AI doesn't just "listen" but also "sees." Computer vision can track how many cars are in line, how fast the kitchen is moving, and even if a customer looks confused at the menu.
The next iteration of the McDonald's AI drive thru will probably be powered by a more robust Large Language Model (LLM) that can handle "multi-turn" conversations. That’s a fancy way of saying it can remember that you asked for no onions three sentences ago even after you got distracted by your kids asking for extra fries.
Practical Insights for the Future
If you're a consumer or a business watcher, here is what you should actually take away from the whole McDonald's AI saga.
First, the tech isn't ready for 100% autonomy. Humans are still essential for edge cases and complex problem-solving. If you're a business owner thinking about "replacing" staff with AI, you should aim for "augmentation" instead. Use AI to take the simple orders, but have a human ready to jump in the second things get weird.
Second, data privacy is going to be the next big battleground. As these drive-thrus get smarter, they collect more data—voice prints, license plates, ordering habits. McDonald's has been quiet about how this data is stored, but as regulations like the CCPA and GDPR tighten, they’ll have to be more transparent.
Lastly, keep an eye on the mobile app. The "real" AI drive-thru experience is actually happening on your phone. When you order via the app and just check in at the stall, you’ve removed the "voice" problem entirely. The app is the most reliable "AI" McDonald's has, and they are doing everything they can to move you toward it with points and deals.

Moving Forward with Fast Food Tech
The failure of the IBM pilot wasn't a death knell for AI in fast food. It was a reality check. The industry learned that "good enough" for a chatbot isn't "good enough" for a drive-thru during a Friday night rush.
To see where this is going next, keep a close watch on these three things:
- The Google Cloud Partnership: If McDonald's announces a new voice pilot, it will almost certainly be powered by Google's Gemini.
- Kiosk Expansion: Since voice is hard, expect more "walk-up" style kiosks even in the drive-thru lanes, or perhaps a "touch-screen" drive-thru experience.
- App Integration: McDonald's will continue to push the "loyalty" app to bypass the need for verbal communication at the menu board entirely.
The goal remains the same: a faster, cheaper, and more accurate burger-buying experience. We just aren't quite at the "Star Trek" replicator stage where the computer understands exactly what we want every single time. Until then, you might still get those extra butter packets by mistake.
To stay ahead of how these changes affect your daily routine or your business, start prioritizing digital-first ordering systems. Whether you are a customer looking for the fastest service or an operator looking for efficiency, the "app-to-curbside" model is currently much more reliable than any voice-activated AI on the market. Watch for McDonald's to roll out its next-gen "automated order taker" by late 2025 or early 2026, likely with a much higher focus on "multimodal" AI that combines voice, text, and visual cues.
