Model overview
These are LoRA fine-tunes of XHToken/Spark-X2.5-4B (recommended) and XHToken/Spark-X2.5-1.7B, for Rizzo Flow. Rizzo Flow turns an unstructured state into typed decisions (`boolean`, `choice`, `score`) with probabilities, and it **generates no text**. The model runs one forward pass per question. The answer is the softmax over the logits of the answer letters (`A`, `B`, …) at the last prompt position. Training works the same way. There is no text target: the loss is a soft cross-entropy between the target distribution and the softmax over the answer letters. Only the LoRA adapters are trained. These GGUF files are what Rizzo Flow downloads by default. It pins this repository by commit and checks the sha256 of every file:

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.
