Takeaways
- Community fine-tune of LFM3-1.7B trained on Claude Opus and Sonnet reasoning traces
- Packaged as GGUF quants ranging from 0.9GB Q2_K to 3.6GB F16
- Runs locally through llama.cpp, Ollama, LM Studio, and agent harnesses like Pi and OpenClaw
- Base model uses a tri-hybrid architecture of convolutions plus sliding-window and global attention across 24 layers
- Inherits 256K context window and roughly 1GB memory footprint at 4-bit precision
- Best suited for offline coding assistance and agentic tool calling, not deep multi-file reasoning
A community release has converted Schnuckade/LFM-3-Coder-Claude-Distill into a set of GGUF files for llama.cpp , Ollama, and LM Studio. The source fine-tune uses Liquid AI’s 1.7-billion-parameter LFM3 model and datasets labeled as Claude reasoning and coding traces.
The package targets offline coding assistance on laptops and other memory-constrained systems. Its recommended Q4_K_M file is about 1.2GB, although inference requires additional memory for context, caches, and runtime overhead.
Three layers behind the release
Three separate artifacts make up the model developers can download:
| Layer | Artifact | Role |
|---|---|---|
| Base model | LFM3-1.7B | Provides the architecture, tokenizer, context window, and agent-oriented post-training. |
| Source fine-tune | Coder fine-tune | Adds coding and reasoning behavior through supervised fine-tuning on logged outputs. |
| Distribution | GGUF repository | Packages the trained weights at several precision levels for local inference engines. |
The GGUF repository is the deployment layer, while training occurred in the upstream fine-tune. That distinction matters when reviewing benchmark claims, licenses, data provenance, or training settings.
A hybrid architecture built for efficiency
LFM3-1.7B uses 24 token-mixing blocks: 13 gated short-convolution layers, five sliding-window attention layers, and six global attention layers. Convolutions process nearby token patterns with relatively low cost, sliding-window attention covers bounded spans, and global attention carries information across longer distances.
The hybrid layout reduces the amount of attention computation compared with an all-attention stack. Liquid AI advertises a 256K-token maximum context window, but practical local limits depend on available RAM, cache precision, runtime settings, and hardware acceleration.
