A few people are running highly quantized models with limited context windows. It's still impressive, but not the benchmark level intelligence. Very few people could afford a rig for reasonable local performance at a reasonable quant, at full context size.
The antirez example is 2.6bit quant, 32k context, and few tokens per second... on a ~$7000 MacBook M5 (new RAM pricing).
Software is one domain where it excels because of structured training data and simulation environments, so I'm well aware it's better here than other areas.
Still there's somewhere balanced between saying every time it's "insufficient or incomplete or outright misleading" and "just trust AI". AI's a useful source of information/reasoning/research, but know you need to validate it's answers for important decisions.
If I take the first chapter of Harry Potter and write a new ending, it's still copyright violation. They took many parts.
I might build one for fun, but it's not going to change the economics alone. Still exciting it's possible.
They were wrong when their on-device model was way behind. They still might be right in the long term.
While multiple app I use might need Gemma 4 E4B, I use dozens of apps and app devs can choose from hundreds of models. A shared cache might reduce size a little when there's overlap, but the core problem still exists. If each app chooses a model disk and memory-swapping explode.
Its probably be better for device manufacturers to bake in a default. I'm not proposing they limit you from using others, but one shared default might be best developer/user experience for 99% of apps.
- Being warm in memory is the single biggest perf speedup you can get, and a default is much more likely to be warm.
- "Best model" is usually "best model for this device" given both RAM and compute. A developer can't test every device but Apple can/will.
- Each model needs to be optimized for the hardware (what's running on ANE, what's running on Metal, what's running on CPU). The default gets optimized.
- If you need custom model, a Lora is probably best (30MB, benefits from all of the above)
You could say the default should be swappable, but that's more a linux ideal than an Apple one so I doubt we ever see that. Plus there are real downsides: intentional or not, prompts end up optimized to the model they are developed for, so swapping the default system model would degrade every app.
- crash recovery: part one is use ADTS aac (even if process crashes, audio is saved up until it does). Part two is isolating the transcription/summaries in separate XPC services.
- disk space: AAC 64kbps mono soles it. Could use Opus for further reduction but both are small.
- speaker bleed: macOS voice isolation processing solves this. It’s a nightmare to get setup, but works great once done.
- library: using argmax SDK - by a bunch of ex-Apple on device AI folks.
It it wasn’t for CoreAudio, I’d say it was easy to make. Argmax, Whisper, and llama.cpp - wrapped in the right architecture, mostly just work.
I’m having fun nerding out on the details like custom vocabulary (get the names of the people in here meeting right), inferring speaker names from transcript, calendar integration, nice UI, etc.
I'd use this.
I'd rather have strong privacy guarantees, but this is still good.
GPT 5.5 genuinely was back on top for a while there, but if you look at the past 2 years, being on Claude was better than being on OpenAI most of the time. If you're going to pick a tool and not switch constantly it was the right choice. Not to mention their tooling has always been ahead, and that gets ecosystem benefits.
Are they close and interchangeable today? Sure. But Sonnet was genuinely way better than anything OpenAI offered for a long time -- the valuation reflects that, not any given moment in time.
