FastContext-4B-SFT_base-Function-Calling-xLAM-Unsloth-GGUF

GGUF quantizations of FastContext-4B-SFT_base-Function-Calling-xLAM-Unsloth for CPU and edge inference with llama.cpp, Ollama, LM Studio, and other GGUF runtimes.

This model is a fine-tune of FastContext-1.0-4B-SFT for function calling, trained with Unsloth on Salesforce/xlam-function-calling-60k.

• Full-precision model: FastContext-4B-SFT_base-Function-Calling-xLAM-Unsloth
• Base model: FastContext-1.0-4B-SFT
• Parameters: 4B

Available Quantizations

| Quant | Size | Recommended Use | File |

|-------|------|-----------------|------|

| Q2_K | 1.67 GB | Smallest, lowest quality — quick tests / very constrained devices | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q2_k.gguf |

| Q3_K_M | 2.08 GB | Small, acceptable quality | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q3_k_m.gguf |

| Q4_K_M | 2.50 GB | Recommended — best size/quality balance | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q4_k_m.gguf |

| Q5_K_M | 2.89 GB | High quality, larger | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q5_k_m.gguf |

| Q6_K | 3.31 GB | Very high quality, near-fp16 | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q6_k.gguf |

| Q8_0 | 4.28 GB | Near-lossless, largest | fastcontext-4b-sft_base-function-calling-xlam-unsloth.q8_0.gguf |

Q4_K_M is the recommended default for most users.
