docs: record the 2026-10-02 swaps — frank-large on ROCmFPX, frank-small on Q5_K_M
frank-large: new runbook frank-large-rocmfpx-q8agent-mtp.md — the ftype-115 tensor-type lock-in that forced the fork, the pinned build (set_rows history), the measured MTP A/B (17.0 vs 7.6 t/s decode, acceptance 0.462), the live client contract (reasoning_content, effort fold, vision restored) and rollback. frank-small: new runbook frank-small-llama-mimo-q5km.md; q6k marked retired (rollback target). gufo runbook marked retired (rollback target). Both indexes, the fleet topology table, the vision/models.yml notes, the benchmarking law and three new Key Lessons updated.

**The shape is chosen by roof math, and the spec decode is the

performance feature.** BF16 decode is LPDDR5x-bandwidth-bound here:
|

13.1 t/s measured = ~94% of the roof for 17.5 GiB of weights — a quant,
|
||||
not a bug. The only way past it is multiple tokens per weight pass.

Measured 2026-10-01 (one session, temp 0, 28,647-token prefill / 512

|
||||
`num_speculative_tokens` beyond 2 is UNMEASURED; both spec arms pay
|
||||
~55–59% of prefill. KV grows only on the 8 full-attention layers
|
||||
(32 KiB/token bf16); the 24 GDN layers hold fixed ~25 MiB state per
|
||||
sequence — so 4 x 262,144 at util 0.45 fits the GTT aperture easily.

||||
**The runtime is not interchangeable — it is chosen by the FILE.**

`kingjones777/Qwen3.8-27B-ROCmFP4-STRIX-MTP-GGUF`'s best rung,
|
||||
`Qwen3.8-27B-Q8_0_ROCMFPX_AGENT.gguf` (28,214,425,952 B, sha256 `f3ef2bda…`,
|
||||
ftype 115 ≈ 8.39 bpw), stores **311 tensors of type 103,
|
||||
`GGML_TYPE_Q8_0_ROCMFPX`** — a quantization that exists in no other loader:
|
||||
stock llama.cpp and gufo both refuse it at load (`unknown tensor type`). The
|
||||
file is 353 F32 + 187 plain-Q8_0 + 311 ROCmFPX; the AGENT routing variant
|
||||
keeps the output-head tensors at plain Q8_0 (187 vs 2 in the non-AGENT file),
|
||||
which is why the card reports MTP acceptance 0.953 vs 0.911 — highest quality
|
||||
AND the better drafter base. Vision comes from the bundled
|
||||
`mmproj-Qwen3.8-27B-BF16.gguf` (931,145,888 B).
|
||||
|
||||
**The MTP head is CROSS-MODEL — the fleet's first.** MiMo ships ZERO
|
||||
`mtp.*` tensors (the reason frank-small's SGLang NEXTN is a 0.00 ghost:
|
||||
SGLang reads the head from the TARGET checkpoint); vLLM reads the draft
|
||||
from a separate path, so `--speculative-config
|
||||
'{"method":"mtp","model":"/models/Qwen3.5-9B","num_speculative_tokens":2}'`
|
||||
drafts from the distill's SOURCE model, and 71%/44% acceptance is the
|
||||
measured proof that the distillation preserved Qwen3.5 hidden-state
|
||||
structure. The alternative drafter (`z-lab/Qwen3.5-9B-DFlash`, fetched;
|
||||
its "PR #40898 unmerged" card claim is false — dflash ships in vLLM 0.30)
|
||||
stays on disk: `FRANK_LARGE_SPEC=dflash` + repoint `SPEC_DIR`.
|
||||
**The pin is load-bearing.** The 2026-08-25 ROCmFPX builds segfaulted in
|
||||
`ggml_compute_forward_set_rows` on exactly this file; `build-rocmfpx.sh`
|
||||
checks the commit out by SHA, so a fork-side force-push cannot silently
|
||||
re-break the endpoint.
|
||||
|
||||
**Spec decode does NOT preserve greedy text here (measured).**
|
||||
Temperature-0 completions differ across arms (bf16 batched verification
|
||||
reorders reductions; near-tie argmaxes diverge and cascade). vLLM spec
|
||||
decode is distribution-preserving, not bitwise-greedy-preserving — do not
|
||||
chase text drift between arms as a regression.
|
||||
**Spec decode is the performance feature, and it is measured.** The draft is
|
||||
the repo's own `mtp-Qwen3.8-27B-Q4_0.gguf` (1,680,271,648 B, sha256 `051a1764…`,
|
||||
`nextn_predict_layers = 1`), pinned to the same card:
|
||||
`--spec-type draft-mtp --spec-draft-n-max 4 --spec-draft-n-min 0
|
||||
--spec-draft-p-min 0.0 --spec-draft-device ROCm0 --spec-draft-ngl 99`.
|
||||
Measured 2026-10-02 in one session, temp 0, 2,202-token prompt / 512 tokens,
|
||||
`cache_prompt: false`, production service stopped for each arm:
|
||||
**MTP on 17.00–17.14 t/s decode** (draft acceptance 0.462, mean acceptance
|
||||
length ≈ 1.86) against **7.60–7.66 t/s with the draft removed — +123 %**;
|
||||
prefill pays 8–15 % (381 → 325–351 t/s). Acceptance is far from the card's
|
||||
0.95 (that number is the card's own text at a shallow prompt); the gain is
|
||||
real and n-max 4 is where it was measured, never swept. This replaces the
|
||||
gufo Q4_K_XL arm at ~15 t/s, so the endpoint got higher quality AND more
|
||||
speed at once.
|
||||
|
||||
**Client contract differs from every llama.cpp-era endpoint:** vLLM emits
|
||||
thinking in **`reasoning`**, not `reasoning_content` — `models.yml` sets
|
||||
`reasoningContentField: "reasoning"` for this provider (miss it and
|
||||
thinking vanishes from transcripts). Tools ride
|
||||
`--enable-auto-tool-choice --tool-call-parser qwen3_coder`. The harness
|
||||
extraBody moved to the Qwen3.5-family recipe (0.7/0.8) with
|
||||
`chat_template_kwargs.{enable_thinking,preserve_thinking}` — a top-level
|
||||
`preserve_thinking` is ignored by vLLM. Env keys stay
|
||||
`FRANK_LARGE_`-prefixed (HIP reads bare `TEMP`/`HOST`/`GPU_MAX_HEAP_SIZE`).
|
||||
**Shape and budget:** ONE session at the native 262,144 window, unquantized
|
||||
f16 KV (~64 KiB/token → ~16 GiB, affordable inside the iGPU's ~114 GiB GTT
|
||||
aperture), `--fit off --flash-attn on --direct-io --ctx-checkpoints 16
|
||||
--cache-ram 8192 --cache-idle-slots`. Measured GTT 64.5 GiB with model +
|
||||
draft + projector resident. Prompt cache verified: a repeat pass over the
|
||||
same 6k prompt replays in 0.5 s.

|
||||
**Client contract (llama.cpp, live-verified 2026-10-02):** `--jinja` is on
|
||||
(without it `chat_template_kwargs` are silently ignored), tools are native
|
||||
(`get_weather` → `{"city":"Seattle"}`), thinking lands in
|
||||
**`reasoning_content`**, `reasoning_effort` accepts ONLY
|
||||
`xhigh|medium|low` (anything else is HTTP 500 — `models.yml` folds `high` and
|
||||
`max` to `xhigh`), and thinking is enabled server-side with the card's
|
||||
recipe (temp 1.0 / top_p 0.95 / top_k 20 / min_p 0) plus
|
||||
`--reasoning-format deepseek --reasoning-budget -1`. Two traps: a request
|

whose whole budget is consumed by reasoning returns `content: null` (bench
|
||||
clients must fall back to `reasoning_content` or they crash *after*
|
||||
measuring), and the fork logs

sha256 `04cf46f2…`) on port 7771. The 2026-10-02 swap was a **quant rung down
|
||||
from Q6_K**, not a runtime change — the llama.cpp path arrived 2026-10-01
|
||||
night for one reason: **asymmetric KV**. `--cache-type-k f16` +
|
||||
`--cache-type-v q8_0` is the fleet's only per-tensor KV lever; SGLang's
|
||||
`--kv-cache-dtype` moves K and V together.
|
||||
|
||||
**The shape is memory-pinned, and the sharp edge is the mamba pool.** The
|
||||
DeltaNet ssm state pool autofills to a fixed ~5.1 GB budget *regardless of
|
||||
dtype* (fp32 at 110 slots, bf16 at 217 — same 5.1 GB), so both dials are
|
||||
pinned: `--mamba-ssm-dtype bfloat16 --max-mamba-cache-size 32` (795 MiB).
|
||||
The KV pool is then **pinned at 606,208 tokens** (`--max-total-tokens`) —
|
||||
the engine's autofit picks 687,388 and leaves 0.53 GB, which Triton's
|
||||
deferred kernel loads eat and the first long request OOMs on. Two
|
||||
262,144-token slots at the model's NATIVE window (2026-10-01 reslice from
|
||||
4 x 151,552: 2 x 262,144 = 524,288 leaves ~82k tokens of pool slack, and
|
||||
a compaction request — frank-primary's trigger is 183,501 tokens plus a
|
||||
32,768-token summary budget = 216,269 — now fits ONE request); a single
|
||||
request may grow to the whole pool. Prefill runs **eager**
|
||||
(`--disable-prefill-cuda-graph`) — there is no headroom for capture;
|
||||
decode graphs are on.
|
||||
**Architecture: qwen3_5 hybrid** — 32 layers, 8 full-attention + 24 Gated
|
||||
DeltaNet, native 262,144 window. KV exists only in the 8 attention layers
|
||||
(4 KV heads × 256 dim × 2 B ≈ 2 KiB/token/layer, ~16 KiB/token for f16 K+V);
|
||||
the DeltaNet state is a fixed per-slot buffer, so slot count — not context —
|
||||
drives that term.
|
||||
|
||||
**No speculative decode — a checkpoint fact.** `text_config` declares
|
||||
`mtp_num_hidden_layers: 1`, but the shipped safetensors (base BF16 and this
|
||||
INT8 conversion alike) carry zero `mtp.*` tensors; NEXTN would draft with
|
||||
an uninitialised 4.24 GiB ghost model at 0% acceptance. The seam gates
|
||||
that no `--speculative-*` flag reaches the engine.
|
||||
**The shape:** `--ctx-size 524288 --parallel 2` = TWO full native windows
|
||||
(llama.cpp divides the pool: `n_ctx_slot = CTX_SIZE / PARALLEL`),
|
||||
`--flash-attn on` (the q8_0-V path is only cheap under flash attention — the
|
||||
seam pins it), f16 K + q8_0 V, all layers on the GPU. Measured VRAM
|
||||
**20,164 / 24,576 MiB**; full f16 V would add ~3.96 GiB and bust the card,
|
||||
which is the whole justification for the asymmetric contract.
|
||||
|
||||
**The venv carries a CUDA 13.0 nvcc extracted from debs** (system nvcc is
|
||||
12.4) so the sgl-kernel/flashinfer JIT compiles for sm86; three local
|
||||
patches ride in the tree (GCC-16 shim, CCCL symlink, rsqrt noexcept).
|
||||
Details in the runbook.
|
||||
Verified at deploy (2026-10-02): `/v1/models` reports `frank-small`; decode
|
||||
**100.4–101.8 tok/s** at temp 0; two concurrent requests answered in
|
||||
parallel; native `tool_calls`; thinking in `reasoning_content`. **Text-only**
|
||||

requests answered; a 170,019-token prompt prefilled in 50.5 s (~3,370 t/s

| Seam | `tests/frank_large_unit.bats` (19 tests: payload gates, deployer/serve parity, spec block, KV dtype, sweep identity) |
|

|
||||
## Why this file, and why only this runtime
|
||||
|
||||
`kingjones777/Qwen3.8-27B-ROCmFP4-STRIX-MTP-GGUF` ships several rungs. Parsed
|
||||
headers of the two candidates:
|
||||
|
||||
| File | ftype | Tensor mix | Output-head tensors at plain Q8_0 | Card MTP acceptance |
|
||||
|---|---|---|---|---|
|
||||
| `Qwen3.8-27B-Q8_0_ROCMFPX_AGENT.gguf` | **115** | 353 F32 + 187 Q8_0 + **311 type-103** | **187** | 0.953 |
|
||||
| `Qwen3.8-27B-Q8_0_ROCMFPX.gguf` | 111 | 2 Q8_0 + type-103 | 2 | 0.911 |
|
||||
|
||||
Two consequences, both measured off the header rather than guessed:
|
||||
|
||||
1. **Quality.** The AGENT routing variant keeps the output-head (and other
|
||||
routing-sensitive) tensors at plain Q8_0 instead of folding them into the
|
||||
ROCmFPX kernel layout — 187 vs 2 — so the logits the sampler reads are the
|
||||
highest-precision tensors in the file. It is also the card's MTP-tuned
|
||||
variant, so it is the *faster* drafter base at the same time.
|
||||
2. **The runtime is forced.** Type 103 is a private extension: stock llama.cpp
|
||||
and gufo both fail at load (`unknown tensor type`). Verified on the host
|
||||
before deploying — the bake-off was not a horse race, it was a lock-in
|
||||
check.
|
||||
|
||||
**The build identity matters as much as the fork.** The 2026-08-25 ROCmFPX
|
||||
builds read this file and then died in `ggml_compute_forward_set_rows` — the
|
||||
exact failure documented in [[kingjones-q8agent-rocmfpx]] when this payload was
|
||||
first attempted on Dankclaw and routed to Dankserver as
|
||||
[[frank-medium-rocmfpx]] instead. `scripts/build-rocmfpx.sh` therefore checks
|
||||
the commit out **by SHA** and refuses to build anything else; the pin is
|
||||
load-bearing, not tidiness.
|
||||
|
||||
## Shape and budget
|
||||
|
||||
One session, the model's full native window, unquantized KV:
|
||||
|
||||
| Dial | Value | Why |
|
||||
|---|---|---|
|
||||
| `--ctx-size` | 262,144 | "one full context" — the native window, no rope scaling |
|
||||
| `--parallel` | 1 | one conversation, all memory to it |
|
||||
| KV dtype | **f16** (both K and V) | ~64 KiB/token → ~16 GiB; free inside a 114 GiB aperture, so there is no reason to pay a quant |
|
||||
| `--fit off` | on | the auto-fitter would silently resize the window we asked for |
|
||||
| `--flash-attn on` | on | required for the long-window attention path to fit |
|
||||
| `--direct-io` | on | bypasses page cache for the 26 GiB weight stream (mmap is disabled by it — deliberate) |
|
||||
| `--ctx-checkpoints 16` | 16 | slot state for checkpoint/rollback |
|
||||
| `--cache-ram 8192` + `--cache-idle-slots` | 8 GiB | prompt cache; verified a repeat pass over the same 6k prompt replays in **0.5 s** |
|
||||
| `--jinja` | on | without it `chat_template_kwargs` are silently ignored |
|
||||
| `--reasoning on --reasoning-format deepseek --reasoning-budget -1` | | thinking in its own channel, unbounded |
|
||||
|
||||
Measured steady state (production, one model copy resident):
|
||||
`mem_info_gtt_used` **63.1 GiB** of the ~114 GiB aperture, `mem_info_vram_used`
|
||||
0.17 / 2.0 GiB (the iGPU's dedicated carve-out is a stub; everything real lives
|
||||
in GTT). llama-server RSS 2.1 GiB. Boot to `/health` 200: **16 s** — the fastest
|
||||
endpoint bring-up in the fleet, because there is no engine compile step.

```
|
||||
|
||||
MTP in llama.cpp is a property of the file, not of the flags: the head is a
|
||||
trained tensor set (`nextn_predict_layers = 1` in this repo's head, arch
|
||||
`qwen35`, 65 blocks) and the draft context runs on the main model's weights, so
|
||||
there is no second 26 GiB copy in memory. See the fleet law in
|
||||
`AGENTS.md → llama.cpp serving`.
|
||||
|
||||
**A/B, 2026-10-02** — same session, temp 0, 2,202-token prompt, 512 tokens,
|
||||
`cache_prompt: false`, `frank-large.service` stopped for every scratch arm (the
|
||||
benchmarking law), baseline arm stripped of `--model-draft` **and** every
|
||||
`--spec-*` flag:
|
||||
|
||||
| Arm | Decode t/s (2 runs) | Prefill t/s | Draft acceptance |
|
||||
|---|---|---|---|
|
||||
| **MTP, n-max 4 (deployed)** | **17.00 / 17.14** | 350.6 / 324.9 | 0.462 (mean acceptance length ≈ 1.86) |
|
||||
| no draft | 7.60 / 7.66 | 381.8 / 381.0 | — |
|
||||
|
||||
**+123 % decode for an 8–15 % prefill tax.** Notes that matter before someone
|
||||
re-litigates this:
|
||||
|
||||
- Acceptance here (0.462) is nowhere near the card's 0.953. The card measures
|
||||
its own short, repetitive text; this is a 2.2k-token prose prompt. Treat the
|
||||
card's number as a file property, not a throughput promise.
|
||||
- `n-max 4` is where the gain was measured; 2 and 8 are **unmeasured**. The
|
||||
gufo-era law applies in spirit — never rank spec settings on a
|
||||
self-predictable corpus.
|
||||
- End-to-end on the chat path is slower than the `/completion` number because
|
||||
thinking tokens are included: a 2,253-token chat prompt generating 512
|
||||
tokens took 43.8 s wall (11.7 t/s end-to-end) — that is the cost of an
|
||||
unbounded reasoning budget, not a regression in decoding.
|
||||
|
||||
## Client contract (live-verified 2026-10-02)
|
||||
|
||||
| Behavior | Observation |
|
||||
|---|---|
|
||||
| Model id | `/v1/models` → `frank-large` |
|
||||
| Tools | native: `get_weather` → `{"city": "Seattle"}` in `tool_calls` |
|
||||
| Thinking | in **`reasoning_content`** (llama.cpp field — *not* vLLM's `reasoning`); `models.yml` sets `reasoningContentField` accordingly |
|
||||
| `reasoning_effort` | accepts **only** `xhigh`, `medium`, `low`; anything else is HTTP 500 (the template raises, it does not clamp). `models.yml` folds `high`/`max` → `xhigh` |
|
||||
| Sampling | server defaults = the card's thinking recipe (temp 1.0, top_p 0.95, top_k 20, min_p 0, presence 0), mirrored in the harness `extraBody` |
|
||||
| Vision | the BF16 projector loads (`loaded multimodal model`); a red square answers **`Red`** (`usage: 75 prompt / 71 cached`) |
|
||||
| Prompt cache | second pass over the same 6k prompt: 0.5 s wall |
|
||||
|
||||
Three traps, all hit for real:
|
||||
|
||||
1. **`content: null` when reasoning eats the budget.** With
|
||||
`--reasoning-parser`-style separation, a request whose `max_tokens` is
|
||||
consumed entirely by thinking returns `message.content = None`. A bench
|
||||
client that indexes `content` crashes *after* measuring and loses the
|
||||
numbers — fall back to `reasoning_content`, or size the budget (200 was
|
||||
enough for the vision probe).
|
||||
2. **`MTP boundary missing for seq_id=… ; resyncing after a non-token step`**
|
||||
appears in the log under draft resets. Self-recovering; not an outage signal.
|
||||
3. **Never `pkill -f llama-server` on Dankclaw** — frank-small is also a
|
||||
`llama-server`. The sweep key here is the payload name:
|
||||
`pkill -f 'Qwen3.8-27B-Q8_0_ROCMFPX_AGENT'`.
|
||||
|
||||
## Operations
|
||||
|
||||
```bash
|
||||
# deploy (planner selects this endpoint only via its own unit/env/serve trio)
|
||||
./scripts/deploy.sh dankclaw --service frank-large
|
||||
|
||||
# status / logs / cause of a crash loop
|
||||
systemctl status frank-large
|
||||
journalctl -u frank-large -n 200 --no-pager
|
||||
|
||||
# rebuild the pinned fork (only when deliberately moving the pin)
|
||||
scripts/build-rocmfpx.sh
|
||||
|
||||
# re-verify the payload without re-downloading
|
||||
scripts/download-frank-large-kingjones.sh --verify-only
|
||||
```
|
||||
|
||||
`serve-frank-large.sh` refuses to start — before touching the port — unless the
|
||||
fork binary, the weights, the MTP head and (unless `FRANK_LARGE_MMPROJ=""`) the
|
||||
projector all exist; `scripts/deploy-remote.sh` mirrors the same predicate so a
|
||||
broken payload never stops the running unit. Caller environment **overrides**
|
||||
`frank-large.env`, and defaults use `:=` so an explicitly empty value surfaces
|
||||
as the error it reads as.
|
||||
|
||||
## Rollback
|
||||
|
||||
git tag **`frank-large-gufo-q4kxl-20261001`**: gufo v0.1.1
|
||||
(`scripts/build-gufo.sh` still on disk), the Q4_K_XL Qwen3.8-27B payload and the
|
||||
DFlash2 drafter all remain on the host. Restore that tag's unit/env/serve trio
|
||||
and redeploy — nothing here deletes anything.
|
||||
|
||||
Payloads retired alongside this swap (MiMo-V2.6 BF16, Qwen3.5-9B MTP source,
|
||||
DFlash draft dirs) are still on disk under `/home/dank/models/` and are the
|
||||
subject of the [[deployment]] disk-pressure note, not of a rollback plan.
|
||||
|
||||
## When it misbehaves
|
||||
|
||||
- **`unknown tensor type` / ftype 115 refused** — something moved off the
|
||||
ROCmFPX binary. Check `readlink -f $(systemctl show frank-large -p ExecStart)`
|
||||
and the fork commit; this file cannot run on stock llama.cpp or gufo.
|
||||
- **SIGSEGV in `ggml_compute_forward_set_rows` during load** — a fork build
|
||||
older than the `36e9acd` pin; rebuild with `scripts/build-rocmfpx.sh`.
|
||||
History: [[kingjones-q8agent-rocmfpx]].
|
||||
- **Slow decode with no log error** — check whether the draft is engaged
|
||||
(`/metrics`, `draft_n` / `draft_n_accepted`; a zero draft count means the head
|
||||
did not load), and check GTT pressure with
|
||||
`cat /sys/class/drm/card1/device/mem_info_gtt_used` — a second resident copy
|
||||
of this model (an orphaned scratch server) drives the whole host into
|
||||
eviction and halves the rate silently.
|
||||
- **`500` naming Jinja** — a `chat_template_kwargs` field reached a server
|
||||
without `--jinja`.
|
||||
- **HTTP 500 naming the template on the first request of a role** — an
|
||||
unmapped `reasoning_effort`; fix the fold in `models.yml`, not the model.

## Identity
|
||||
|
||||
|Field|Value|
|
||||
|---|---|
|
||||
|Endpoint|`192.168.0.143:7771`, served alias `frank-small`|
|
||||
|Runtime|llama.cpp **master** (qwen35 model support), CUDA build `sm_86`, at `/home/dank/GitPackages/llama-master/build-cuda/bin/llama-server` — unchanged across the quant swap|
|
||||
|Payload|`bartowski/MiMo-V2.6-Distill-Qwen-9B-GGUF` **Q5_K_M**, 6,876,124,704 B (6.40 GiB), sha256 `04cf46f2b5584ef922697d6c063f94879434fb86c467f1a09e52daf0cddaf35f`, at `/home/dank/models/MiMo-Q5KM/` (fetched by `scripts/download-frank-small.sh`)|
|
||||
|Unit|root `frank-small.service` (repo `scripts/frank-small.service`, `User=dank`, relinked), env `scripts/frank-small.env`, serve `scripts/serve-frank-small.sh`|
|
||||
|Repo pins|`tests/frank_small_unit.bats` (stub-argv seam + the VRAM arithmetic), `deploy_llm_small` gates in `scripts/deploy-remote.sh`|
|
||||
|
||||
## Shape and the KV contract
|
||||
|
||||
`--ctx-size 524288 --parallel 2` — llama.cpp divides the pool across slots, so
|
||||
each session gets `n_ctx_slot = 262144`, the model's full native window (boot
|
||||
log confirms `n_slots = 2, n_ctx_slot = 262144, kv_unified = 'false'`).
|
||||
|
||||
The KV contract is Frank's: **K unquantized (f16), V `q8_0`** —
|
||||
`--cache-type-k f16 --cache-type-v q8_0`. Two hard dependencies ride on it:
|
||||
|
||||
- **`--flash-attn on` is mandatory**: quantized V exists only on the FA path.
|
||||
Without the flag the engine falls back silently and the contract becomes a
|
||||
lie. The serve script pins the trio; the bats seam pins the script.
|
||||
- The VRAM budget: attention KV lives in the 8 full-attention layers only
|
||||
(4 KV heads × 256 dim). K f16 ≈ 16 KiB/token, V q8_0 ≈ 8.5 KiB/token
|
||||
(34 B per 32-element block) ⇒ ~24.5 KiB/token over the 524,288-token pool ≈
|
||||
**12.5 GiB**. Weights 6.40 + KV 12.5 + Gated DeltaNet state (~25 MiB/slot) +
|
||||
compute buffers/CUDA graphs ⇒ **20,164 MiB measured** against the card's
|
||||
24,576 MiB.
|
||||
|
||||
**Why the quant step did not buy a bigger window.** The model cannot be run
|
||||
past its trained 262,144 without scaling, and two of those windows are already
|
||||
the pool's ceiling. The 0.86 GiB the smaller quant frees is margin, not
|
||||
geometry. It is also not enough to un-quantize V: f16 V costs 16 KiB/token
|
||||
instead of 8.5, i.e. +3.96 GiB on this pool, which lands past the card. That
|
||||
arithmetic is a test (`the KV budget fits the 3090…`), so a future CTX_SIZE or
|
||||
quant change that breaks the fit fails the suite instead of the boot.
|
||||
|
||||
## Measured on this file (2026-10-02)
|
||||
|
||||
|Check|Result|
|
||||
|---|---|
|
||||
|Boot to healthy|~20 s, `n_slots = 2`, `n_ctx_slot = 262144`|
|
||||
|VRAM|20,164 MiB / 24,576 MiB (`nvidia-smi`)|
|
||||
|Decode, temp 0, no thinking|**100.4–101.8 tok/s** (256–512 token completions at ~900-token depth)|
|
||||
|Two concurrent requests|both answered, 256 tokens each in 3.2 s wall (slots are real)|
|
||||
|Tools|native `tool_calls` with correct arguments (`get_weather {"city":"Seattle","unit":"c"}`)|
|
||||
|Thinking|`reasoning_content` populated on a reasoning-requiring prompt|
|
||||
|
||||
## Client contract
|
||||
|
||||
- Thinking arrives in **`reasoning_content`** (`--reasoning-format deepseek`),
|
||||
the field `models.yml` reads for this endpoint.
|
||||
- **Thinking is off unless the request asks**: the MiMo GGUF template defaults
|
||||
`enable_thinking` false, so `models.yml` ships
|
||||
`chat_template_kwargs: {enable_thinking: true, preserve_thinking: true}` in
|
||||
`extraBody`. A raw client that omits it gets a direct answer — measured, and
|
||||
not a fault. Trivial questions produce no thinking even with the flag on.
|
||||
- Tools: `--jinja` + server-side parsing, verified 2026-10-02.
|
||||
- **Text-only.** This GGUF carries no vision tensors. The HF repo does ship a
|
||||
paired `mmproj-MiMo-V2.6-Distill-Qwen-9B-bf16.gguf`, so vision is one
|
||||
`--mmproj` away if it is ever wanted here (frank-primary is the fleet's
|
||||
vision endpoint today).
|
||||
|
||||
## No spec decode
|
||||
|
||||
The GGUF has no MTP tensors (the same fact that made SGLang's NEXTN a 0.00
|
||||
ghost), and the cross-model DFlash draft
|
||||
(`/home/dank/models/DFlash-Qwen35/qwen3.5-9b-dflash-Q8_0.gguf`) is an
|
||||
optimization candidate, not a default — acceptance has to be measured on this
|
||||
traffic first. The bats seam fails if a draft flag ships unannounced.
|
||||
|
||||
## Rollback
|
||||
|
||||
|Target|How|
|
||||
|---|---|
|
||||
|Q6_K, same runtime|`scripts/frank-small.env` `MODEL_FILE=/home/dank/models/MiMo-Q6K/MiMo-V2.6-Distill-Qwen-9B-Q6_K.gguf` (7,793,710,624 B, still on disk) and the deployer's `LLM_SMALL_MODEL_FILE` default|
|
||||
|SGLang + INT8|[[frank-small-sglang-mimo-v26]] — venv and payload both remain on disk; the fetch recipe moved to `old/download-frank-small-sglang-int8.sh`|
|
||||
|
||||
## When it misbehaves
|
||||
|
||||
- Port 7771 dark: `journalctl -u frank-small -n 50`; the serve script exits 1
|
||||
naming the missing file if the binary or GGUF moved.
|
||||
- `No CUDA GPUs are available`: the 3090 vanished from the bus or the UVM node
|
||||
is missing — `nvidia-modprobe -u -c=0` (the serve script runs it).
|
||||
- Requests queue behind each other: two concurrent long generations are the
|
||||
slot ceiling by contract.
|
||||
- Slow decode after a CTX or quant change: check `nvidia-smi` — pushing KV out
|
||||
of VRAM into unified memory halves the rate silently.
