| # LFM2.5-1.2B-Instruct-DSpark-GGUF | |
| GGUF build of [`LiquidAI/LFM2.5-1.2B-Instruct-DSpark`](https://huggingface.co/LiquidAI/LFM2.5-1.2B-Instruct-DSpark) for **llama.cpp** (DSpark speculative decoding is in mainline, ggml-org/llama.cpp #25173). | |
| This is a standalone **draft sidecar**: it carries only the drafter (5 attention layers, rank-256 Markov head, confidence head, block size 9). Token embeddings and the LM head are shared from the target model at load time, so it must be paired with a [LFM2.5-1.2B-Instruct-GGUF](https://huggingface.co/LiquidAI/LFM2.5-1.2B-Instruct-GGUF) target file. | |
| Find more information about LFM2.5-DSpark in our [blog post](https://www.liquid.ai/blog/lfm2.5-dspark). | |
| ## π¦ Files | |
| | file | quant | size | notes | | |
| |---|---|---:|---| | |
| | `LFM2.5-1.2B-Instruct-DSpark-F16.gguf` | F16 | 594 MB | best accept length, recommended when memory allows | | |
| | `LFM2.5-1.2B-Instruct-DSpark-Q8_0.gguf` | Q8_0 | 315 MB | accept length β2% vs F16 | | |
| | `LFM2.5-1.2B-Instruct-DSpark-Q4_K_M.gguf` | Q4_K_M | 174 MB | accept length β3% vs F16, smallest recommended β sub-4-bit draft quants measurably hurt both accept length and throughput | | |
| Draft quantization changes speed only marginally (the drafter is a small share of each cycle); choose by memory budget. The target model quant is the main speed/quality lever and is independent of this file. | |
| ## π How to run (llama.cpp) | |
| ```bash | |
| llama-server -m LFM2.5-1.2B-Instruct-F16.gguf \ | |
| -md LFM2.5-1.2B-Instruct-DSpark-F16.gguf \ | |
| --spec-type draft-dspark --spec-draft-n-max 10 --spec-draft-n-min 0 \ | |
| -fa on -ngl 99 | |
| ``` | |
| The block size is read from the sidecar metadata (n-max is clamped to it). Speculative decoding is **exact**: the target verifies every proposed token, so greedy output equals the target alone; per-response `timings` report `draft_n` / `draft_n_accepted`. | |
