IMO running local models "well" still requires an expensive hardware investment. You really want 96GB of VRAM on a modern Blackwell arch to run these models with decent KV cache. Trying to run them on a unified memory Mac, an AI Max AMD processor, or a DGX Spark-alike is really just asking for trouble. Prefill kills perf.
If you throw the right GPUs at the problem, they become much better - but still not quite in the realm of Sonnet or DeepSeek 4 Flash, let alone Opus / DeepSeek Pro or Mythos/Fable/GPT-5.5.
Given enough budget, power, and cooling, you can run some pretty good data pipelines, but for code, I think it still makes sense to shell out to an API provider most of the time.
For a fraction of the price of 96GB vram, I built a desktop based on a supermicro server mobo and EPYC 9 series CPU, with just under 400GB rdimm ram (approx $4500 all in but this was before the ram price hike). Works really well for serving larger local modals at a decent enough speed (I consider anything more than 10 tokens/second usable and value accuracy over speed).
FWIW I think it might be both.
Ultimately if you skip over the opportunity to play with these models on your own machine you are losing out on a lot of really interesting educational opportunities — it helps make a lot of stuff feel more concrete in a way that only tinkering can.
But then I think once I had an idea of something that I was building against Gemma 4 or Qwen 3.6 I would be looking at openrouter etc., to stabilise it for the next tier of experimentation (and to get back a kind of multi-device access without tailscale/lm link etc.).
Are they good enough to replace what people seem to want to do with Claude? Maybe not. But it's an unparalleled learning opportunity.
Depends what you need the model to do. The recent granite4.1:3b just takes 2GB of memory and is fast. Results are pretty good and support tool calling. Barely a squeak out of the Mac laptop.
Even faster with the MLX builds.
Then when I need more heavy lifting I fire up a larger model.
IMHO the issue isn't the models. I've had OpenClaw give the same results as Claude using open models locally. Slower but does the job. Something that can do optimal model switching is what's needed.

That RTX6000Pro you mentioned is $12k.
Yep - I'd say either that or 4x 5090 is a great entry point to running local models "well". Two of them would be even better. If you don't have $12-24k to spend, you can try your hand with tiny models or quants or slow speeds, but it will be a much more painful experience. You're already giving up a lot by dropping down from frontier models - you're giving up even more by trying to squeeze them into little RAM and compute.
Prices will fall in the next few years. Maybe just play with the tiny toy models for now to learn how they work, then keep using API providers until they do.

these are not mutually exclusive anymore. DS4 has set the bar for me these days. https://github.com/antirez/ds4
someone just put this on my radar yesterday, im about to try this today. how's your experience with it?
me thinks there's a lot of optimization strats we're currently leaving on the table just because the amount of things to explore and test are so expansive. but this one is super interesting targeting metal primarily and zeroing in on one model. instead of a one size fits all llama.cpp im very interested to see if theres a future where super tailor-made variants per model pans out to harnesses that can rapidly switch ultimately providing something akin to sonnet/early opus territory (that's my personal bench mark of good-enough i shall now cancel the hell out of this claude sub)
I'm on the verge of cancelling my anthropic $20 plan since it's come out. On an M5 Max 128GB, hooked up to the pi.dev harness, I get in the neighborhood of 400-450tps prefill and 30-35tps generation. It is imminently usable and at times feels more stable than my previous CC setup. Occasionally there are things it struggles with that I will bounce back over to CC for, but it is highly usable. The future is bright for local models! As a tinkerer, it makes me really happy to have a local setup I can be just as productive in, and not have the token overlords ready to shut me down at any time.
That's DS4 Flash right? How does it feel in intelligence and speed compared to DS4 Flash hosted by Deepseek themselves or another API provider? I've been using API DS4 Flash for a lot of personal projects and have been quite impressed. I've spent $1 on building ~10 toy projects and gotten them all to work within the bounds of what I wanted without having to do much besides guide the model away from dumb loops.
I'm using the DS4 flash IQ2 2-bit quant, per Salvadore's recommendations for my hardware in the repo. I haven't messed with the cloud hosted variant. The only other paid API I have messed with is a $20 Anthropic sub, primarily with whatever the latest version of Sonnet is. For the most part, this local configuration feels on par with that.
With this configuration (set up over the last month) I have been working on Python data processing tools, an internal Svelte 5/SvelteKit data intensive BI app, and some smaller Rust projects. It's been doing really well there.
If I could just save up $6000 I could sell off my RTX 5090 for $4,000 and buy an RTX 6000 Blackwell Pro Workstation. I can fit models into the 32GB of vram but my context window ends up being tiny for any halfway capable model.
Isn’t the RTX 6000 Blackwell Pro Workstation over $13000 now?
Not really, Qwen 27b offloads to a decent gaming GPU (RTX 4090 in my case) without needing tons of RAM.
can you give more info? llama.cpp vs vllm? config? i wanna try specifically this model
