LLM quantization impact on long context performance debated

By PulseAugur Editorial · [1 sources] ·

A user on the r/LocalLLaMA subreddit is investigating whether higher quantization levels in large language models are necessary for maintaining performance with very long contexts. They observed that a Qwen Flash Next model at q8 quantization performed better than a q6 version when tested with contexts around 300-400k tokens. The user hypothesizes that the increased context length might amplify small differences in quantization, leading to more noticeable performance degradation in lower-quantized models. AI

IMPACT Higher quantization may be necessary for maintaining LLM accuracy with extremely long contexts, impacting deployment strategies.

    For long context does high quant matter?

    <!-- SC_OFF --><div class="md"><p>Question: if I'm regularly at higher context - say 300-400k - do higher quant versions of the same model perform better? I'm thinking something like Qwen Flash Next q6 and q8. I recently swapped from q6 to q8 and performed a/b testing. I original…
