Spark-X2.5-cmf

infosave · Spark-X2.5-cmf

Spark-X2.5-4B and Spark-X2.5-1.7B (hybrid attention: three 512-token sliding-window layers per full layer, 1M-token context, thinking mode, tool calling, 200+ languages) packaged as single CMF files. They run with `cortiq`, a Rust inference engine with no Python and no ML framework: NVIDIA, AMD and Intel GPUs through Vulkan/DX12, Apple silicon through Metal, and the CPU. Use cortiq 0.8.12 or later; prebuilt binaries for Linux, macOS and Windows are on the releases page. The engine picks the GPU and its settings itself. `--no-think` asks for a direct answer; without it the model reasons in a ` ` block first, so raise `--max-tokens` (default 256). All files are quantized from the bf16 checkpoints. Perplexity: the first 4096 tokens of wikitext-2 test with the BOS token in front; the unquantized models score 10.61 (4B) and 14.49 (1.7B; transformers in float32 gives the same 14.49). Spark is sensitive to 4-bit attention and down projections, so only gate/up are 4-bit in the compact files.

常见问题

开放权重是否代表可以免费商用?

不一定。应核对具体版本许可证、商用门槛和使用政策。自部署还会产生算力和维护成本。

这些价格是实时结算价格吗?

不是实时结算价格,而是带采集时间的来源报价快照。请到对应渠道核对当前版本、区域、折扣和计费方式。
