BENCHMARKS × LOCAL MEMORY

Choose the test.
See what your Mac can run.

Compare models on the Artificial Analysis benchmark that matters to you. Every local family stays on the graph: runnable models use their highest-fidelity comfortable build, while models beyond your Mac are muted at their smallest available build. The cloud rail traces Claude, Gemini, and GPT intelligence over time.

Detail & table build

The practical local default. Native MXFP4 checkpoints are used when that is the model’s published four-bit format. The graph independently picks each family’s best-fitting build, or its smallest build when none fit.

MULTI-TOKEN PREDICTION

One pass. More than one token.

Qwen3.6 was trained with extra prediction heads. A compatible runtime can use them for speculative decoding: propose several future tokens, verify them together, and accept the ones the main model agrees with.

HOW GENERATION CHANGES

01Draft

The MTP heads predict the next few tokens cheaply.

02Verify

The full model checks those candidates in parallel.

03Accept

Correct candidates advance generation several tokens.

This changes decoding, not the Artificial Analysis capability score. Rejected drafts are discarded, so Unsloth reports no accuracy change from enabling MTP.

File sizes are summed from matching GGUFs in both Hugging Face repositories, checked July 26, 2026. The disk delta is exact for the selected artifact; speed and extra runtime memory are Unsloth-reported ranges. Like counts refresh from the Hugging Face Hub API and are summed across repositories, not deduplicated users.

Speed is hardware-dependent. Unsloth recommends trying draft counts 1–6, although two performed best on average. Their measured acceptance fell from 83% at two drafts to 50% at four, making extra drafts less useful.

Current llama.cpp support requires MTP-aware settings. Parallel slots above one and the multimodal projector are not yet supported with this path.

File size is not peak runtime memory. Context length, KV cache, multimodal projectors, and the inference engine add overhead. The benchmark score belongs to the base model—not to each quantized file.

UD

Unsloth Dynamic: model-specific mixed precision, assigning more bits to sensitive layers.

IQ

Importance-aware quantization, designed to retain more useful signal at very low bit counts.

K

llama.cpp superblock quantization. S, M, and XL distinguish recipes that spend progressively more storage.

Q4_0 / Q4_1

Older uniform 4-bit formats. Widely compatible, but less selectively allocated than newer recipes.

Do not rank these files by tokens/second from size alone. Unsloth warns its per-quant throughput measurements are noisy; MTP draft acceptance, hardware bandwidth, and runtime settings can matter more than a small size difference.

READ THE FINE PRINT

Two sources, two different claims.

01

Scores come from Artificial Analysis

The selector changes the independent model evaluation shown on the vertical axis. Missing evaluations are omitted, never treated as zero. Intelligence scores use the v4.3 index, refreshed September 18, 2026, with models released since added from the same index version on September 22. Values estimated by Artificial Analysis are marked “AA estimate”; inherited quantized-model scores are marked “base score.” Coding and Agentic are archived September 1 scores, and remain separate from the current index.

02

Sizes come from Hugging Face

Artifact sizes are the summed byte sizes of the named files in the linked repositories, including multi-part builds and native quantized checkpoints.

03

Quant scores are not implied

Artificial Analysis evaluates a model endpoint or base model. The app does not pretend every Q4, Q6, or Q8 artifact preserves that score exactly.

04

Fit leaves working room

“Comfortable” keeps 20% of unified memory free. Actual runtime needs still vary with context and cache precision. Each family appears once: the highest-fidelity comfortable artifact when one fits, otherwise its smallest available artifact in gray.
