Operator, 2026-09-10: # "replace that a4b moe over pfish-6 -- remove the pfish-6 alias and create an alias # for char-rp-fast." REPLACES the `Pfish-6` alias, which is removed with this change. # # The seat itself is unchanged in every dimension that matters to a caller: the A4B is # 30 layers / kv 8 / sliding_window 1024 / 128 experts top-8 — field for field the same # geometry as Pfish-6 — so the 9.114 GB KV pinning transfers exactly and the seat still # reports 534,649 tokens and 2.04x concurrency at 262,144. That was verified from the # engine log, not assumed, because KV-per-token is normally NOT transferable. # # ⚠ Pfish-6 IS GONE from this gateway and its seat no longer serves that name. A caller # still asking for `Pfish-6` gets a clean 404 rather than a silent substitution, which is # the intended behaviour. The artifact is still on disk (see the ROLLBACK note above). # # SAMPLERS, and they are the author's, not inherited: the model card states Temp 0.8-1.0 # and MinP 0.05. Temperature/top_p/top_k already come from the tree's own # generation_config (1.0 / 0.95 / 64) which vLLM applies server-side, and 1.0 sits at the # top of the card's stated range, so the only value that needs stating here is min_p. # Deliberately NOT copying char-rp's temp 1.1 / min_p 0.10 — those were A/B-tuned against # a retired Mistral seat and are inherited, not canonical, as that block's own note says. # # enable_thinking:false is ALSO pinned process-level on the seat # (--default-chat-template-kwargs). Stated here as well so the intent is visible at the # routing layer: without it the gemma4 reasoning parser pre-initialises to REASONING and # plain prose comes back with a null `content`. # # ⚠ ITS FIRST QUANT WAS BROKEN AND SERVED NaN. The 2026-09-10 08:15 build was made with # the DENSE recipe, whose ignore list has no router regex, so all 30 MoE routers were # quantized to 4 bits — a 4-bit router picks different experts (playbook §3.15). The seat # came up healthy, answered every request with 120 tokens, and decoded to the empty string; # logprobs were NaN. Re-quantized with services/erp-seat-quant/quant_nvfp4a16_gemma4_moe.py, # whose target guard refuses that exact mistake. The broken tree is parked on ana-ml2 as # ...-NVFP4A16.BROKEN-routers-quantized-20260910.

Its ClickHouse member spewed # ~94 GB of unrotated logs and filled ana-docker's disk; the trace UI was redundant # with LiteLLM's native spend_logs (store_prompts_in_spend_logs: true → full # prompts/responses/tokens/cost at :4000/ui).
