Ollama tag for Qwen2.5-Coder 3B model fails to generate code

By PulseAugur Editorial · [1 sources] ·

A user encountered an issue where a specific Ollama tag for the Qwen2.5-Coder 3B model, quantized at q3_K_M, failed to generate functional code. Despite the model loading and processing requests normally, it produced nonsensical output for simple coding tasks. However, this failure was not due to the quantization level itself, as the official Qwen GGUF version of the same model and quantization level, when imported with the correct template, successfully solved the same tasks.

    An Ollama tag that pulls and runs and has no working code in it. The same model at the same quantisation, elsewhere, is fine.

    <p><strong>TL;DR</strong>: <code>ollama pull qwen2.5-coder:3b-instruct-q3_K_M</code> succeeds, <code>ollama run</code> streams at normal speed, and nothing anywhere reports a problem. On three trivial HumanEval-style tasks it produced <strong>no implementation at all</strong> — 0…
