Model overview
MLX (Apple Silicon) build of **GLM-5.3-Flash** — 320B-A18B hybrid of 34 Kimi-Delta linear-attention layers and 11 DeepSeek-sparse-attention (NoPE MLA + lightning indexer) layers with manifold-constrained hyper-connections — quantized to **4-bit experts / 8-bit everything else**. **These files are modified**: converted from the upstream bfloat16 release (GLM-5.3-Flash-BF16) to MLX and quantized; the architecture is unchanged. The multi-token-prediction layer (layer 45) is not included. The vision tower is carried in bfloat16. `glm5_next` landed in mlx-vlm `main` on 2026-08-26 (no release carries it yet). Validating that port against `transformers` 5.16 at tiny scale found two numerical bugs and two epsilon mismatches, which the runtime in https://github.com/PipeNetwork/glm53-flash-mlx fixes; parity is **1e-6** end to end, exact on cached decode.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
