S1-mini · GGUF
Two GGUF builds of S1-mini by Superwhisper, the speech-transcript normalizer, made for Lathe, a local push-to-talk dictation app for Windows. Superwhisper publishes F16 and Q4KM at superwhisper/s1-mini-GGUF; these fill the gap between them.
Q4KM was observed dropping whole clauses from dictations; neither build here did on 202 test inputs. Where Q6_K mixed differs from F16 it is nearly always punctuation, or a filler removed that F16 kept.
Q8_0: llama-quantize on the upstream F16, no importance matrix (Q8_0 does not use one).
Q6_K mixed: Q6K with an importance matrix calibrated on 266 real dictations in the model's own prompt format, then per tensor: the output head and the six blocks a sensitivity sweep found most fragile (0, 11, 16–19) at Q80; attn_v, attn_output, ffn_up, ffn_down at Q6K; `attnq, attnk`, `ffngate` at Q5K; the token embedding at Q4K.
Full comparison of fourteen builds, including the recipes that did not beat plain Q8_0, in Lathe's docs.
Prompt format
S1-mini has a fixed contract: the system prompt below verbatim, then a control line and the raw transcript, thinking disabled, greedy decoding.
<|im_start|>system
You are a text normalizer for speech-to-text transcripts. The input begins with a control line specifying the styling, structure, and context settings; clean the transcript to match those settings and output only the cleaned text.<|im_end|>

okay so can you send me the the file from yesterday not the older one thanks<|im_end|>
