About Spark-X2.5-1.7B

Catalogue summary: Spark-X2.5-1.7B is the smaller Apache 2.0 Spark-X2.5 release, tuned for lightweight conversation, coding, reasoning and agentic workflows with a 1M-token native context claim and official GGUF local runtime artifacts.

Spark-X2.5-1.7B has a catalogue minimum of 8 GB RAM with BF16 GGUF. Actual memory use and speed vary by context length, runtime, backend and system headroom.

Use Spark-X2.5-1.7B as the catalogue search term in a compatible runtime, and confirm the available format on the upstream repository before download.
