Looking backward: today's $5k box can run GPT-4o-quality models, roughly 1.5–2 years behind the current frontier. Looking forward: closing that remaining gap to Claude Sonnet 4-class takes considerably longer — and the reasons are now precise.
Each marker is either a frontier release date (above the line) or the estimated year that quality becomes locally runnable on a sub-$5k box (below). Hover the dots for detail.
The forward estimate depends on two uncertain variables: how fast MoE and distillation close the quality-per-VRAM gap, and how fast consumer hardware gets high-bandwidth memory. Drag the slider to explore.
Starting from "FLOPs alone would say 2027" and accounting for each real constraint in turn.
Indexed to 1.0 = full Claude Sonnet 4 quality locally. The horizontal line is the target. Three paths differ in how fast hardware and model efficiency improve.
| Estimate | Previous | Revised | Key reason for change |
|---|---|---|---|
| Current lag (reverse) | ~3 years (GPT-3.5 tier) | ~1.5–2 years (GPT-4o tier) | MoE models (Qwen3-30B-A3B) bring GPT-4o quality to a single 24 GB GPU. Previous estimate used dense 14B as ceiling. |
| Forward: task-level parity | 2028–2029 | 2028–2030 | No consumer GPU in 2026 delays the hardware step; RTX 60 series ~2028 is the next meaningful jump. |
| Forward: full-product parity | 2031 (single-year estimate) | 2030 (base), 2029–2032 range | MoE quality acceleration pulls date in; bandwidth and VRAM stagnation push it back. Net: pull in by ~1 year, widen the range slightly. |
| Main bottleneck | "Memory" | Memory bandwidth and VRAM capacity (not FLOPs) | FLOPs/$ improves on the 2.1-year doubling. Bandwidth/$ is essentially flat at consumer flagship tier over 5 years. These are different constraints. |
| Biggest accelerant | Model efficiency (vague) | Sparse MoE with small active param count | Qwen3-30B-A3B (3B active, GPT-4o quality) is the clearest proof. Future models may push this further — a 100B-total MoE with 5B active and frontier quality would be transformative. |
