Layout: GPU 0 = cyberprev (KV 16 -> 15 GiB, 1.29x), erp-seat (moved from GPU 1, KV 8.49 -> 5.5 GiB, 1.32x), voices (ctx 8,192 -> 40,960, its native maximum, KV 6 GiB, 1.07x), coder (moved from GPU 1, ctx 16,384 -> 32,768, the card maximum, 2.35x), parakeet-nemo. GPU 1 = gen-small (moved from GPU 0, 5.5 GiB, 1.76x), meromero-rp (22 GiB, 1.32x), intern-decision. Sizing rule: KV >= 1.25x max context rounded up to 0.5 GiB, checked against 7 days of LiteLLM traffic and the engines' own KV-usage logs. Each card keeps spare memory for its bursty tenant (parakeet's cap on GPU 0, intern-decision's 32k call on GPU 1). YaRN extensions are not enabled: they do not fit, and the Qwen cards warn static YaRN degrades short prompts. gen-small gets --override-generation-config max_new_tokens 32768. It applies only to requests that omit max_tokens (vLLM get_max_tokens) and answers 9 runaway ~260k-token replies in 7 days; the longest normal reply was 6,357. Applied with playbooks/fv-ml1-rebalance-20261005.yaml (boot-check guard and health/KV verification per seat); all nine seats healthy, gateway smoke tests pass.

# ── Memory ── FIRST-BOOT values, expected to be tuned to a sane concurrency band

# 2026-10-01: 0.33 live (.env on fv-ml1). The KV is byte-pinned by GEN_SMALL_KV_CACHE_MEMORY, so util only sets
|
|
# the boot check (Free at start must be >= util x total). Lowering it freed GPU 0 slack for parakeet-nemo
|
|
# at zero KV cost (still 670,142 tokens / 2.56x). Before ANY restart, check the arithmetic:
|
|
# util x 95.6 GiB <= measured Free + this seat's own resident memory. Do not trial-boot.

# 2026-10-05 (Prime): KV 8 -> 5.5 GiB (~461k tokens, ~1.76x) so parakeet-nemo can stay on GPU 0.

# at ~60 MiB free after 1-2 days of creep. 2.5 GiB back covers parakeet's hard cap (MEM_CAP_MIB
|
|
# 3840, i.e. +1,732 MiB over its 2,108 rest) with ~0.9 GB spare at the plateau.
