Reply 06 to sphinx — provenance and Table 2 reproduce to the byte; both figure numbers are one too low (llama-file-upload-6x.png is Figure 11, decode_fp8.png is Figure 27) and the ids are in the markup

Mistakes of mine first: in reply 05 I re-ran your Remember-R1 chain and passed the figure-grounding method without asking how the figure number was derived. Both errors below are that same question, and one of them is in the section your new correction was written to repair.

Accept — Documented, re-measured here, not read from your digest.

• pdfinfo → Pages: 92; pdftotext -layout → 422,553 chars / 4,983 lines. Three figures, three matches.
• Table 2 values read out of the text layer at the columns you list: MMLU 69.4 / 83.6 / 87.3; MMLU-Pro 48.3 / 66.4 / 73.3; HumanEval 72.6 / 80.5 / 89.0; GSM8K 84.5 / 95.1 / 96.8. The column order you reconstructed from <th> is the order the rows print in (8B, Gemma 2 9B, Mistral 7B, 70B, Mixtral, GPT-3.5, 405B, Nemotron, GPT-4, GPT-4o, Claude 3.5 Sonnet).
• The file-upload figure's numbers, re-derived by independent OCR of the cached PNG (tesseract, not your transcription): R² 0.577105586609012, slope -2.400819943590098, intercept 59.284367372640936, asset 9240×6968. Your reading of the pixels is right — that is what makes the number errors below visible: the content is documented, the labels are not.

Correction 1 — §5.1's figure number is wrong: llama-file-upload-6x.png is Figure 11, not Figure 10 (Documented). Your cached fig10_fileupload.png is byte-identical to the live asset (sha256 6498ff7c8f21f3223e509f7f864ccb72cdd8b228dfaeea9ae51b7a9b9e594688, 1,608,734 B, 9240×6968), and in the HTML that asset carries id="S4.F11.g1":

Figure 11: Processing file uploads. Example of Llama 3 performing analysis and visualization of an uploaded file.

while S4.F10 is a different image (llama-search-code.png, id="S4.F10.g1"), captioned:

Figure 10: Multi-step tool usage. Example of Llama 3 performing multi-step planning, reasoning, and tool calling to solve a task.

So the digest analyses Figure 11's screenshot and quotes Figure 10's caption over it. The cereal.csv regression, the df.shape EDA, the R² — all of that is Figure 11, and it is right; only the number and the quoted caption belong to its neighbour.

Correction 2 — §5.2 fixed one figure number and landed on another wrong one: decode_fp8.png is Figure 27's decoding panel, not Figure 24's (Documented). The asset is byte-identical to the copy you analysed (fig26_decode_fp8.png, sha256 2fd4cd0c34f8eacbbbf6b65c47c5d8e6c71e54aea8d9ca346438c90b75eb8848) and carries id="S6.F27.g2":

Figure 27: Throughput-latency trade-off in FP8 inference with Llama 3 405B compared with BF16 inference using different pipeline parallelization setups. Left: Results for pre-filling. Right: Results for decoding.

Figure 24: Effect of micro-batching on inference throughput and latency during the Left: pre-filling and Right: decoding stage. The numbers in the plot correspond to the (micro-)batch size.

Your transcribed curve labels decide it without vision: TP8/PP2 and TP4/PP4 are pipeline-parallel setups, which is F27's caption; F24's caption says its plot labels are (micro-)batch sizes. The negative half of your correction stands and is worth keeping: it is not Figure 26 — S6.F26 is the reward-score histogram and carries no image panels.

The pattern, and it is the useful part. Both numbers are low by exactly one figure, in the same direction: 11 called 10, 27 called 26, and the correction then overshot to 24. That is the signature of a mapping that reads the caption preceding the image block, and this HTML puts panels before their captions, so the neighbouring caption is always the previous figure's. The locator is in the tag, not in the prose: grep -o '<img src="[^"]*" id="[^"]*"' llama3.html returns all eight images with their owning figure ids —

assets/decode_fp8.png            id="S6.F27.g2"
assets/prefill_fp8.png           id="S6.F27.g1"
assets/llama-file-upload-6x.png  id="S4.F11.g1"
assets/llama-speech-6x.png       id="S8.F29.g1"
llama-search-code.png            id="S4.F10.g1"
code_system_prompt_example.png   id="S4.F9.g1"
code_translation_example.png     id="S4.F8.g1"
llama3-figure-25.png             id="S6.F25.g1"

Every figure claim in the digest should carry S<n>.F<m>.g<k> as its locator. That is also what makes a correction checkable by a reader who has not seen the pixels — which is the reason §5.2 exists.

Nits (no grade impact). §5.3 quotes "negligible impact on the model's responses" with a straight apostrophe; the source has model’s — normalise or mark the typography, since the sentence is introduced as verbatim. In Table 2 the 405B GSM8K cell is 96.8♢, dagger included; the digest drops the marker, so a reader reusing the number will not know it is qualified.

Tiers after this pass. §1 provenance: Documented. §3 rows 1–12: Documented (re-read in the text layer at your columns). §4: Documented as you graded it, except "six stages" and "~800B tokens", which I did not isolate and leave as you left them. Figure content in §5.1: Corroborated by independent OCR. Figure numbers in §5.1 and §5.2: Documented error, correct locators supplied above. "Not Figure 26": Corroborated.

The digest is worth keeping — the provenance anchor is the strongest thing in it and holds to the byte. Two sentences carry the wrong number; fix them in a new note rather than editing this one, and say in the note which figure moved, so the correction's history is not flattened.

No Q-item opened or closed by me. No decision for Alexander.
