| # FreeToken macOS MLX Reproducibility Evidence |
|
|
| Machine-readable, redacted evidence for a native macOS Apple-Silicon |
| deployment of the [FreeToken](https://github.com/FlashML-org/FreeToken) |
| deployment interface, produced by the companion |
| [`chengyixu/freetoken-macos-deployment`](https://github.com/chengyixu/freetoken-macos-deployment) |
| kit and validated against its published JSON Schema. |
|
|
| ## Dataset description |
|
|
| | | | |
| | --- | --- | |
| | **Experiment ID** | `freetoken-macos-mlx-20260822-001` (immutable) | |
| | **Recorded** | 2026-08-22T19:32:23Z | |
| | **Outcome** | Pass — healthy server accepted `max_tokens=1`, returned non-empty content (HTTP 200/200, 0.291 s) | |
| | **Schema** | [`schema/one-token-experiment.schema.json`](https://github.com/chengyixu/freetoken-macos-deployment/blob/main/schema/one-token-experiment.schema.json) (v1) | |
| | **Network exposure** | `127.0.0.1` (loopback) only | |
| | **Redaction** | No credentials, tokens, or private endpoint data | |

|
| ## Provenance and pins |
|
|
| | Component | Pinned value | |
| | --- | --- | |
| | Upstream software | FreeToken `v0.1.2`, commit `0ab982f10905fa775962a4eddcb44caa50065251` | |
| | Compatibility implementation | `freetoken-macos-compat-mlx` | |
| | Model | [`mlx-community/Qwen3.5-4B-MLX-4bit`](https://huggingface.co/mlx-community/Qwen3.5-4B-MLX-4bit), revision `32f3e8ecf65426fc3306969496342d504bfa13f3` | |
| | Runtime | `mlx-lm==0.31.3`, `mlx==0.32.1`, `mlx-metal==0.32.1` | |
| | Host | macOS 27.0, Apple Silicon `arm64` | |
| | Sampling | `temperature=0`, `max_tokens=1`, streaming disabled | |
|
|
| ## Intended purpose |
|
|
| This dataset exists to make the macOS compatibility claim **falsifiable**: |
| anyone can diff the recorded request/response against the schema and the |
| pinned configuration, then re-run the documented protocol on their own Apple |
| Silicon host to confirm or refute the result. |
|
|
| ## Out-of-scope uses |
|
|
| This is a single one-token smoke-test record. It must **not** be used as: |
|
|
| - evidence that FreeToken's CUDA kernels, cache/offload scheduler, or |
| bandwidth-adaptive MoE method execute on Apple Silicon; |
| - a throughput, latency-distribution, memory, or cost benchmark (one token is |
| a control-plane smoke test, not a performance measurement); |
| - evidence of model quality — the recorded completion is not an evaluation |
| result; |
| - a substitute for the upstream paper's experiments |
| ([arXiv:2608.16157](https://arxiv.org/abs/2608.16157)), which remain |
| independently unreplicated here. |
|
|
| ## Limitations and generalization |
|
|
| Results come from one host (macOS 27.0, one Apple-Silicon generation), one |
| quantized checkpoint, one MLX runtime version, and one trial. They do not |
| generalize to other Macs, model families, or runtimes. Unified-memory pressure |
| and warm-cache state are uncontrolled. See |
| `data/macos-mlx-implementation-2026-08-22.md` for the full interpretation |
| boundary and the companion repo's |
| [threats-to-validity](https://github.com/chengyixu/freetoken-macos-deployment/blob/main/docs/threats-to-validity.md) |
| document. |
