|
|
# 2026-10-03 (Frank, second move): the rung went Q5_K_M -> Q6_K with the pool
|
|
# HELD at 401,408. The freed third slot funded exact f16 V first; the ~3.5 GiB
|
|
# still free funds the +875 MiB of weights (file delta 7,793,710,624 -
|
|
# 6,876,124,704). Projected landing ~2.7 GiB free — inside the 2-3 GiB floor,
|
|
# so MEASURE after the boot; if it lands under 2 GiB, step the pool down one
|
|
# 12,288-token (384 MiB) increment.
|
|
#
|
|
# 2026-10-03 (Frank): TWO streams instead of three, each one WIDE — 200,704
|
|
# tokens per conversation, above the 200,700 the harness compacts at — and the
|
|
# KV cache is now FULLY UNQUANTIZED (f16 K, f16 V). The two moves are the same
|
|
# move: llama.cpp divides --ctx-size across --parallel slots, so the slot given
|
|
# up is exactly the VRAM that pays for unquantized V. No further quantization
|
|
# anywhere on this endpoint.
|
|
#
|
|
# Three measurements on this card, this runtime, price the terms:
|
|
# 2 x 262,144, no projector: 20,190 MiB used / 4,386 free
|
|
# KV = 524,288 tok x 24.5 KiB = 12,800 MiB => non-KV (weights 6,557 +
|
|
# DeltaNet state ~25/slot + compute buffers + CUDA graphs) = 7,390 MiB
|
|
# 3 x 196,608, projector on: 22,972 MiB used / 1,153 free
|
|
# KV = 14,113 MiB => non-KV WITH the vision tower = 8,859 MiB
|
|
# 3 x 180,224, projector on: 21,684 MiB used / 2,441 free (the 2026-10-02
|
|
# shape) => non-KV = 8,748 MiB
|
|
# Two slots give back one DeltaNet state (~25 MiB). Priced at f16 K+V
|
|
# (32 KiB/token) this pool is 12,544 MiB, so the prediction is
|
|
# 12,544 + ~8,800 = ~20.9 GiB used, ~3.1 GiB free — the band the 2026-10-02
|
|
# shape hit, bought with precision instead of a slot. The 1024 ubatch
|
|
# re-prices the compute buffers upward, so MEASURE after any change: if the
|
|
# boot lands under 2 GiB free, step the pool down in 12,288-token
|
|
# (384 MiB at this rate) increments.
|
|
#
|
|
# KV arithmetic: attention KV exists only in the 8 full-attention layers
|
|
# (4 KV heads x 256 head_dim x 2 B) = 16 KiB/token for K and the same again for
|
|
# V => 32 KiB/token, so 12,288 tokens (= 6144/slot) is one 384 MiB step — that
|
|
# is the ladder to walk if this moves again. Two native windows (2 x 262,144)
|
|
# are NOT reachable with full-precision V: 524,288 x 32 KiB = 16.1 GiB of KV
|
|
# against a card with ~15.7 GiB of KV room once weights, the vision tower, the
|
|
# DeltaNet states and the graphs are loaded. 200,704 per stream is what full
|
|
# precision buys; q8_0 on V would buy 262,144 instead.
|
|
#
|
|
# The asymmetric-KV contract this endpoint was created for (Frank, 2026-10-01
|
|
# night: f16 K + q8_0 V) is now spent — it existed to make a third slot fit,
|
|
# and the third slot is gone. The flags stay explicit so the choice is visible
|
|
# in the argv either way.

# Compute-buffer geometry. This endpoint passed neither flag until 2026-10-03,
|
|
# so it ran on llama.cpp's own defaults (2048/512); the pair is now 4096/2048.
|
|
# Both are tunables because the pair is a measurement, not a law — and the
|
|
# measurement is CARD-SPECIFIC. On the 2x R9700 layer-split sibling the ubatch
|
|
# curve peaks at 512 and every step up costs GiB of compute buffer for no
|
|
# speed (see frank-medium-batch-ubatch). On THIS CUDA 3090 the curve climbs
|
|
# monotonically to 2048: 710 -> 1188 t/s prefill from ubatch 1024 to 2048 on
|
|
# the 35B MoE sweep, 1944 -> 2423 t/s on the Ornith 8k sweep, with decode flat
|
|
# to under 1 t/s on every rung. Ubatch is a prefill knob; decode never moves.
|
|
#
|
|
# The logical batch is free — two independent sweeps agree that at a fixed
|
|
# ubatch, 2048/4096/8192 give identical prefill speed AND identical peak VRAM,
|
|
# because the compute buffers are sized by the ubatch alone. Doubling it costs
|
|
# nothing and buys nothing; it is here because it is the value the pair was
|
|
# measured at.
|
|
#
|
|
# THE RISK IS ALL IN THE UBATCH. The 1024 -> 2048 step cost ~1,244 MiB of peak
|
|
# graph VRAM on the 35B MoE (7,330 -> 8,574 MiB); this 9B hybrid has far
|
|
# smaller compute tensors, so the delta should be well under that, but the
|
|
# predecessor Q5_K_M shape recorded "ubatch 2048 failed the scratch boot" at
|
|
# ~3,571 MiB free. This shape ships with LESS free (2,815 MiB measured
|
|
# 2026-10-05). Compute buffers are allocated at graph capture during BOOT, so
|
|
# a failure is loud and fast, not a surprise at the first long prompt. MEASURE
|
|
# nvidia-smi free immediately after the deploy: under ~1.5 GiB, or a boot
|

# failure, step down to 4096/1536 (or 4096/1024, the last known-good rung).
