Model overview
Runs on **SparkInfer, SGLang and vLLM** unmodified — configs for all three are below. Serving many users at once? See concurrency. **SparkInfer × this NVFP4 build × the DSpark v2 drafter** — an engine, a checkpoint, and a speculative drafter optimized against each other, compounding to **4.3×**. The drafter never changes what the model says: the target verifies every drafted token. **GeForce RTX 5090–specific** NVFP4 checkpoint of `Qwen/Qwen3.8-27B`, quantized with NVIDIA Model Optimizer. Serves the **full native 262,144-token context** on 32 GB.

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.

Estimate monthly base token costs
Estimates exclude cache discounts, tiered pricing, multimodal surcharges, web search, taxes and additional reasoning output.

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.
