There is one number that decides what you can run locally, and it is not the model's parameter count or your CPU. It is VRAM. Below are the tiers as our catalogue actually computes them — how many models fit each card size at Q4_K_M or better, which to reach for, and where the meaningful thresholds sit. The short version: 24 GB is where local AI stops feeling like a compromise, and the step up to it matters far more than the step beyond it.

Every figure here is computed rather than collected. VRAM is model weights, which are parameters × bits-per-weight ÷ 8, plus a KV-cache term for the context length, plus about a gigabyte of runtime overhead for the CUDA context and activations.
The tiers below assume an 8,000-token context and count only <strong>Q4_K_M or better</strong>. Q3_K_M and below fit more models on paper but show visible degradation, so counting them would overstate what each card genuinely does well. A longer context costs more than the table says; a shorter one costs less.
Counting models understates the step. What changes between 16 and 24 GB is not just how many models fit but how good the best one is. On Artificial Analysis's Intelligence Index, the strongest model reachable at 16 GB scores around 22. At 24 GB it is <strong>52</strong>, because 24 GB is where the 27B class lands.
For scale, GPT-6 Astra scores 61 on that index and Claude Fable 5.1 scores 66. A model you run on a single 24 GB card at no cost per token now sits within roughly nine to fourteen points of the frontier on the same measure. That is a materially different proposition from where local models stood two years ago.
The step from 24 to 32 GB, by contrast, adds four models and some headroom. If you are choosing hardware, the money is far better spent getting to 24 GB than going beyond it.
Two rules cover most of the decision, and they matter more than any specific recommendation because the catalogue moves every month.
A tier list is a snapshot. Two forces move it, and they move in opposite directions.
New releases push capability down the tiers: a model published this quarter at 27B frequently matches what needed 70B a year ago, so the same card reaches further over time without any hardware change. Meanwhile the frontier keeps moving up, so the gap in absolute terms does not close as fast as the local numbers improve.
The practical advice is to re-check rather than memorise. The counts above were computed from our catalogue at the time of writing, and our <a href="/models">Model Explorer</a> recomputes them against the current catalogue and your specific hardware every time you open it. A tier list tells you roughly where you stand; the explorer tells you exactly.
The honest framing is a split rather than a replacement. Local models do not match a frontier model on the hardest reasoning, and they do not need to for most of what gets sent to one.
Boilerplate, renaming across files, format conversion, first-draft tests, commit messages, documentation, summarising diffs and answering questions about a codebase all run acceptably on a 14B or 32B model. That work is high-volume, which is exactly what makes it expensive on a hosted model at $50 per million output tokens, and exactly what makes it free locally.
Run the volume locally, keep a frontier model for the genuinely hard problems, and the bill collapses without quality falling where it matters. Most people find the split lands near 80/20 by volume and close to the inverse by value.
Tier choice is a hardware-buying decision as much as a software one, and the cost curve is not linear with capability.
Second-hand cards deserve a mention here. VRAM capacity is what gates model choice, and an older card with more memory frequently beats a newer one with less for this specific purpose — a case where the usual buying advice inverts.
Our <a href="/models">Model Explorer</a> takes your exact GPU, RAM and backend and ranks every model that fits, which is more precise than any tier list can be. The <a href="/gpu">GPU pages</a> break the same maths down card by card, and the <a href="/lab">lab pages</a> track what each publisher has actually released as weights.
Tell it your GPU, RAM and backend, and it ranks every open-weight model that actually fits your machine.
