PROFILE_GUIDANCE
This is a conservative estimate, not a benchmark. It should help readers understand the likely local AI ceiling for this hardware class and then route them to the calculator or a fuller setup article.
Use the [RAM/VRAM Calculator](/tools/ram-vram-calculator), then read the most relevant setup page: [/compare/best-local-ai-setup-for-mac](/compare/best-local-ai-setup-for-mac).
A model that technically loads may still be constrained, unstable, or memory-limited for ordinary use. Treat “fits” and “feels good” as different questions.

LIMITATIONS
·Conservative estimate, not a benchmark
·Local AI Guide has not independently benchmarked this hardware.

UPGRADE_ADVICE
·Use the RAM/VRAM calculator, lower context, choose smaller models, or move to more memory before assuming a larger model will fit.

CAVEATS
·Conservative estimate, not a benchmark.
·Actual results depend on model, quantization, context length, runtime, GPU offload, drivers, thermals, and other running apps.
·Local AI Guide has not independently benchmarked this hardware.
