New Model Spark-X2.5: 4B variant matches Qwen 3.5 9B
insraq · reddit · 2026-09-01
A new model series Spark-X2.5 (4B/1.7B params) appeared on Hugging Face, featuring a custom architecture rather than a standard fine-tune.
- Performance: The 4B variant claims benchmark scores neck and neck with Qwen 3.5 9B.
- Support: It doesn't run out-of-the-box on llama.cpp yet; a pending PR and a custom fork are available.
The community is discussing early experiences with the model.
