# J-space, open models — companion file for language models This file accompanies the interactive article at https://eliebak.com/viz/jspace-open-v2 (reading modes: `article`, `figures`; figures are numbered Fig. 1–27 and addressable as `#fig-N`). It is meant to be loaded into a language model's context so the model can explain the article and its figures to a reader. **Who wrote this.** This file was compiled by an AI agent (Claude) working with Elie Bakouch. Quantities marked MEASURED were re-derived by the agent from the committed result files of the repository below, not copied from its prose. Passages marked INTERPRETATION are the agent's reading of the data, not established results. **Source repository.** https://github.com/eliebak/open-jlens-data (experiments run 2026-07-08 → 2026-07-11 on a Slurm H200 cluster). The paper being extended: Anthropic's "Verbalizable Workspace", https://transformer-circuits.pub/2026/workspace. ## Conventions in this file - Claims carry one of three labels. MEASURED: a number re-derived from the repository's committed result files. DESCRIPTION: what a figure shows, with no inference. INTERPRETATION: the compiling agent's reading of the data. - Scope, unless a section states otherwise: 4–6 open models from 1–3 families, WikiText as the fitting corpus, context windows of 128 or 4,096 tokens. - "Undecidable from this data" marks cases where two hypotheses fit the data equally well; the data does not distinguish them. ## Revision history - Earlier materials about this work describe the middle band as "distance-invariant" or say its influence "stops fading". The seq-4096 re-measurement (E1 below) found that flatness was mostly an artifact of the 128-token measurement window. The current window-robust statistics are the decay exponent α and the cliff ratio. - An earlier report quoted E5 noise margins of 30–500×; the floor's prompts overlapped its reference. The corrected margins are 13–93×. ## Where to verify numbers All paths relative to the source repository's root. | Quantity | File | |---|---| | any per-figure number | `*_analysis.npz`, `summary.json` under the experiment's `results/` | | E1 metric definitions | `E1_horizon/RESULTS.md` | | the window-censoring revision | `AMENDMENTS.md` (2026-07-11 entry), `E1_horizon_4k/RESULTS-4k.md` | | E2 segmentation and trajectories | `E2_training/SYNTHESIS.md` | | E3 retrieval / injection | `E3_transplant/REPORT.md`, `REPORT-2b.md` | | E4 bend statistics and seed triples | `E4_delphi/` results | ## Known limitations - The E4 bend rests on a single 25B fit with a nonstandard 8-shard merge. - cum90 absolute values are unreliable: the pursuit explains ~1% of activation energy at the top of the ladder, and the smallest models press against the 64-atom cap. The relative 10× fall is the supported statement. - The "unrelated models score CKA 0.5–0.7" calibration is corpus-dependent (0.44–0.70 across E5x pairs and corpora). - The E1 cliff-on-boundary coincidence rests on two models (qwen3-1.7b, qwen3-4b) plus one training trajectory (SmolLM3); other models show related but not identical structure (olmo: step up into a flat deep block; gemma-1b: no unambiguous k2 deep boundary). - E6 is descriptive only: two MoE models, one on a reduced prompt budget. - All E4/E1/E2 headline numbers are WikiText-fit; E5 measures how much the fitting corpus moves them. ## The measurement (article section: "The measurement") MEASURED protocol. For a model reading text, J_ℓ = E[∂h_final,t′ / ∂h_ℓ,t]: the Jacobian of the final residual state with respect to layer ℓ's residual state, averaged over source/target positions and prompts. Projected through the unembedding: V_ℓ = P·J_ℓ, where P holds the unembedding rows of 4,096 frozen token ids (RandomState(0) over the model's vocab; per-model conventions such as gemma's (1+γ) gain and tied/untied embeddings are recorded in the repo). V_ℓ is a 4,096 × d "dictionary": one steering vector per common token. Standard fits use 250 WikiText prompts (the reference fits in `neuronpedia/jacobian-lens` used n = 460–670 with stopping rule delta 0.002). Two summary numbers: - **CKA** (centered kernel alignment). Center V's rows, form the relation table K = V̂V̂ᵀ (4,096 × 4,096), and compare two tables by CKA(A,B) = ⟨K_A,K_B⟩ / (‖K_A‖‖K_B‖). Invariant to any rotation of a dictionary; sensitive to changes in the *relative* geometry of the 4,096 entries. Calibration (MEASURED): two independent fits of the same model ≈ 0.997 (250-prompt vs 470-prompt endpoint check); two different trained models at matched depth ≈ 0.5–0.7 on prose (corpus-dependent, see E5x). - **PR** (participation ratio). PR = (Σλ_i)² / Σλ_i² over the eigenvalues of the dictionary's covariance: the effective number of directions the 4,096 entries span. Real layers: roughly 200–600 in the band. PR is quoted in the middle band because near the output the measurement collapses into the output matrix. MEASURED noise scale: a 32-prompt fit already lands within band 1−CKA ≈ 0.005 of the full 250-prompt fit (from sub-sampled shard lenses of qwen3-1.7b). The repo's recombined-J convention is a pair-SUM per source position (a constant ×56.0 vs the pair-mean on the 128-token layout) — the constant cancels in CKA and PR. INTERPRETATION: the block structure visible in every layer-by-layer CKA map (an input-side block, a long middle "workspace" block, a small output-side block) is the page's organizing object. Block edges ("boundaries") are quoted as a fraction of depth ρ = layer / (n_source_layers). ## E1 · temporal horizon Question: the paper reads the middle band as a workspace that "holds things in mind"; taken literally a band nudge should out-last nudges elsewhere. Never measured before because the standard fit averages over all future positions. MEASURED setup: Δ-resolved fits. effect_ℓ(Δ) = ‖P·J_ℓ(Δ)‖_F on source–target pairs exactly Δ tokens apart. Six models: gemma3-1b-pt, gemma3-1b-it, qwen3-1.7b, qwen3-4b, gemma3-27b-it, olmo3-32b. Sequence length 128, skip_first 16, 250 prompts, 9 buckets with centers Δ = 0, 1, 2, 3.5, 6.5, 12.5, 24.5, 48.5, 96. Why Δ=1 is the reference: at Δ=0 the measurement is dominated by the position's own residual/identity path (effect(1) < ½·effect(0) at every layer of every model; the naive Δ=0 half-life saturates below one token everywhere). Cross-token metrics (MEASURED definitions): - r1 = effect(1)/effect(0), "crossing fraction": 0.21–0.36 at early/mid layers, 0.014–0.06 at the deepest layers, across the six models. - h1 = first Δ where effect < ½·effect(1) (log2(1+Δ) interpolation), "half-life". - flatness = effect(96)/effect(12.5); tail_frac = effect(96)/effect(1). Both are window-relative (see the 4k re-measurement). MEASURED results: - The paper's literal prediction fails in all six models: h1 peaks at ρ = 0.03–0.17 every time; band half-lives are 2–5 tokens. Sharpest case: gemma3-1b-pt h1 = 20.8 tokens at L3 (ρ=0.12); instruction tuning cuts that early far tail ~4× (it: 5.1). - The cliff: cross-token influence collapses within 1–2 layers at ρ ≈ 0.6–0.7. qwen3-1.7b r1 steps 0.202→0.158→0.133→0.117→0.077 across L16–L20; cliff at ρ = 0.667 = the model's own k2 CKA boundary. qwen3-4b: 0.657 (2.3× scale change). olmo3-32b shows a step *up* into a distance-flat deep block instead; its E1 boundary replicates E2's segmentation digit-for-digit (k2 ρ = 0.4127). gemma-1b has no unambiguous frozen k2 deep boundary; the analog is a far-field plateau at L15–16 against the exploratory k3 sub-boundary at ρ = 0.68. MEASURED — the seq-4096 re-measurement (the window correction). Motivation: with seq 128, Δ≈96 pairs can only start from sources in the first ~40% of the window (position confound). Re-fit at sequence length 4,096: qwen3-1.7b (112 full-length prompts, effects accumulated at 160 log-spaced targets per prompt — per-bucket means unbiased; recombined dictionary matches the standard fit at r = 0.996) and gemma3-1b-it (200 prompts, r = 0.987). 14 buckets out to Δ ∈ [2049, 4095]. Results: - The in-band flatness 0.562 (seq-128) collapses to 0.264 in the clean window; the seq-128 far buckets were inflated ×1.8 ([33,64]) to ×2.7 ([65,127]). - Beyond the old window every layer decays as a scale-free power law effect ∝ Δ^(−α) with no plateau out to Δ ≈ 1,500. α (qwen, fitted Δ=12.5–1536): ≈ 0.59 sensory / 0.72 band / 0.77 motor. gemma-it replicates the collapse and the depth ordering (0.55 / 0.56 / 0.67, fitted Δ=12.5–384; its sliding-window attention layers add architecture-specific structure noted in the repo). - The cliff is exactly Δ-independent: the drop ratio at qwen's deep boundary is 2.21–2.44 at every bucket from Δ=2 to Δ=4095. - No induction-band bumps: all 13 cross-token buckets decay monotonically at every layer (0 upticks). MEASURED mechanism ablations (gemma-1b): freeze attention patterns → every layer profile unchanged (r = 0.996–0.9999); ablate the value path → only 5–14% of cross-token reach remains; ablate calibrated previous-token/copy heads → change < 10⁻³. INTERPRETATION: the reach is content carried through fixed attention patterns, and it is not simple copying. INTERPRETATION (the honest summary): influence shrinks with depth — deeper layers pass a smaller fraction across tokens, keep it for fewer tokens, and (in the two long-window fits) decay with a steeper exponent — with one sharp feature on top, the cliff. Beyond the measured window there is no data, not a null. ## E1×E2 · the horizon through training MEASURED: the Δ-resolved fit repeated on 12 public SmolLM3-3B checkpoints, 0.095 → 11.19 trillion tokens (tokens = step × 2.37e6). Tracked quantities: - temporal cliff = depth where r1 first falls below 70% of its mid-band median: ρ = 0.6286 at the first checkpoint (0.85% of training) and unchanged for 11 of 12 checkpoints (final: 0.60). - CKA boundary (each checkpoint's own k2 segmentation): starts ρ = 0.457, migrates onto the cliff (0.629) over ~6T tokens. - in-band flatness (band fixed to the final checkpoint's): trendless, 0.38–0.42, from 0.095T to 11.19T. - band÷sensory r1 ratio: 0.50 at the first checkpoint → ≈1.0 by ~3T, then locked. INTERPRETATION: the temporal feature exists before the geometric boundary arrives; the geometry converges onto it. Training never extends the reach; what matures is the flat-inside-band shape of the r1 profile. ## E2 · emergence MEASURED setup: 27 checkpoints across SmolLM3-3B (12), OLMo-32B (11), and an early OLMo-7B set (random init, 4.2B, 16.8B, 67B tokens). All comparisons use matched-depth mean CKA (layer ℓ vs layer ℓ, averaged over layers). Blockiness (MEASURED definition): (mean within-block CKA, off-diagonal) − (mean between-block CKA), at the dynamic-programming segmentation minimizing within-block dissimilarity; block count k = argmax_k [blockiness − 0.02(k−1)]. Caveat the article states and you should repeat: a blockless map whose agreement decays smoothly with layer distance already scores 0.16–0.27 under this rule (Toeplitz surrogate null). The excess over that null — the actual block signal — is +0.01 to +0.09 across trained checkpoints. The random init selects k=2 with raw blockiness 0.127, but its "blocks" align with nothing: depth-correlation to trained checkpoints ≈ 0, and its matched-depth CKA to the 32B run starts at 0.31 and falls to 0.17 as that run trains. MEASURED trajectories: - Structure is present at the earliest trained checkpoints (4.2B tokens OLMo-7B, 95B SmolLM3). Both OLMo scales pass through a blockiness *minimum* near ~17B tokens (7B: 0.113; 32B: 0.111) — a dissolve-and-reform — before differentiating. Blockiness peaks mid-training (32B: 0.363 at 1.09T; 3B: 0.296 at 3.0T) and softens toward the end (0.311 / 0.207 final). - Rate of change, (1 − matched-depth CKA between consecutive checkpoints) / ΔT: OLMo-32B falls roughly as 1/t and never reaches zero — its final state scores CKA 0.836 against itself 200B tokens earlier. SmolLM3's rate stops falling at ~3T and holds constant to the end (consecutive-checkpoint CKA ≈ 0.77–0.79 per 1.5T interval). One 20–56×-above-trend point in the 32B contains both a data-mix change and the LR anneal; cause undecidable. - Distance to final state: rises from 0.48 (SmolLM3 first) / 0.52 (32B first) toward 1.0, with no plateau before the end. - 7B × 32B cross-grid: at the shared token count (16.8B) the two agree at CKA 0.668 (depth-corr 0.936) — inside the unrelated-trained-models range. Best matches: 7B@16.8B ↔ 32B@42B (2.5× more tokens), 7B@67B ↔ 32B@92B (1.4×). The 4.2B row's best match is the earliest 32B checkpoint available (censored). FLOPs-matching would predict the opposite direction (32B has ~4.6× fewer tokens at equal FLOPs). INTERPRETATION: what "never settles" means concretely: layer by layer, the relation table keeps being rewritten — entries change direction relative to one another (a rigid rotation would leave CKA at 1.0). Token count, not compute, sets a checkpoint's geometric age, and the bigger model ages more slowly per token. ## E3 · transplant Question: unrelated models' dictionaries look alike (CKA 0.5–0.7 matched-depth); is the code causally interchangeable? MEASURED setup: pairs Llama-3.1-8B ↔ Qwen3-8B (cross-family; 4,096 token-string matches, 85% hit rate) and gemma-3-4B ↔ 27B (cross-scale; identical tokenizer). Frozen 3,276 / 820 train/test split. Maps: ridge (inner 90/10 λ selection) and semi-orthogonal SVD (pure rotation). All fits pre-existed in `neuronpedia/jacobian-lens`. MEASURED retrieval (rank the mapped held-out vector against all 4,096 receiver entries; chance 2.44e-4): best cosine retrieval@1 at matched mid-depth — svd llama→qwen 0.922 (r@5 0.995), gemma 4b→27b 0.849–0.863. Identity map (possible when d matches): 0.000–0.001. Shuffled pairing: ≤ 0.002. Note a metric subtlety the agent found worth flagging: llama→qwen svd scores 0.000 under *euclidean* ranking but 0.922 under cosine — a pure norm-scale effect. MEASURED injection: 48 hand-vetted single-token concepts from the held-out split × 7 neutral carrier prompts; baseline recall 0/336 (median concept rank ≈ 48,000); injection adds α·r̄_ℓ·û at a block output, α = 0.5–32 in units of the receiver's typical residual norm. Best success@1 per direction: 0.940 (svd, L17, α=32, into qwen), 0.961 (ridge, L20, α=3, into llama), 0.756 (into 27B), 0.560 (into 4B). All three control arms (random semi-orthogonal rotation, right map + shuffled concept, norm-matched random vector) score 0.000 over all 104,832 control cells (48 × 7 × 8 α-values × 3 arms × 13 layer–direction combinations). MEASURED cost accounting (KL = fluency guard, KL(baseline‖injected) excluding the concept token): the mapped vector needs 1.0–5.9× the KL budget at which the receiver's own vector saturates; capped at the own vector's budget, cross-family transfer is 0.41–0.69; at its own operating point it reaches 94–99% of the own-vector ceiling at equal KL (gemma pair: 56–76%). INTERPRETATION: that a pure rotation suffices means the two dictionaries are congruent shapes, not merely statistically similar. Scope limits to repeat: headline rates are each direction's best (layer, α) cell of a sweep; all concepts are common vocabulary; rare words untested. ## E4 · scale MEASURED setup: the Delphi suite (one architecture/dataset/tokenizer, 447M–25B). Compute-optimal ladder 3e18 → 1e23 FLOPs, a fixed-compute (isoFLOP) slice of six sizes, seed triples at 1e21 (3.4B params) and 1e22 (9.7B). "Band PR" here = the maximum PR over layers with ρ ∈ [0.25, 0.75] (in practice PR at ρ ≈ 0.70–0.75). MEASURED: - Ladder band PR: ≈208 at 3e18 rising to ≈444 (1e22), then 379 at 1e23. A single power law across the ladder is rejected once seed-measured noise is used (heteroscedastic test p ≈ 0.002–0.014; seed log-σ(PR): 0.017 at 3.4B, 0.185 at 9.7B). Whether the top is flat (break at ≈2.1e20 FLOPs) or slowly saturating is undecidable — both fit equally well, and the 25B is a single fit with a nonstandard 8-shard merge (per-shard convergence 0.028–0.064 vs ≤0.0036 elsewhere). Four early-ladder fits stopped early on convergence. - One surface fits ladder + isoFLOP slice + seeds: PR ∝ d_model^0.58 · (tokens per parameter)^(−0.13) — training *compresses* (~26% per 10× tokens/param). An undertrained 8.1B measures 520 vs the fully-trained 25B's 379. At fixed compute, PR rises with parameter count. - cum90 (matching pursuit on held-out band activations, 64-atom cap, 50 prompts × 111 positions, band median): falls 49 → 5 across the same ladder. Caveats: the two smallest models press against the 64-atom cap; at the top of the ladder the pursuit explains ~1% of activation energy. The 10× fall is the finding; the absolute counts are not reliable. - Seeds: pairwise band CKA 0.846–0.850 (3.4B) and 0.903–0.914 (9.7B) — between the cross-family level (0.76) and the adjacent-layer level (0.995). Seed PR values: 386/385/375 (3.4B); 444/492/344 (9.7B) — shape agrees, the number does not. INTERPRETATION: a bigger dictionary, consulted more sparsely; growth in span stops (or nearly stops) around 2×10²⁰ FLOPs while per-token usage keeps collapsing. All of E4 is WikiText-measured — see E5 before treating any PR as a model property. ## E5 · corpus dependence (and E5x · cross-model, by corpus) MEASURED setup: refit the lens on Python code, web math, and PDF-extracted prose for gemma3-1b-pt, qwen3-1.7b, qwen3-4b, delphi-3.4b; noise floor = a second WikiText fit on fresh prompts, same budget (band CKA ≈ 0.99). MEASURED (within-model): input-side layers are rewritten wholesale (qwen3-4b code × wikitext at the first layers ≈ 0.26 vs floor 0.99); output side moves least but never reaches the floor. Block structure survives every corpus. Band PR (qwen3-4b): code 594, math 498, wikitext 329, PDF prose 202 — a swing comparable to E4's whole ladder, 13–93× above the floor across models. (An earlier internal report quoted 30–500× margins from a floor whose prompts overlapped its reference; 13–93× is the corrected range.) MEASURED (E5x, cross-model on the same corpus): qwen3-1.7b × qwen3-4b band means — code 0.56, wikitext 0.67, math 0.69, PDF prose 0.70. gemma3-1b × qwen3-1.7b — code 0.44, math/wikitext 0.53, PDF prose 0.57. Doubling the prompt count moves these by < 0.001. Depth-correspondence (correlation between a layer's depth and its best match's depth) also weakens on code. INTERPRETATION: code — the corpus that inflates each model's own dictionary the most — makes two models look *least* alike. The shared, transferable geometry lives in ordinary prose; code exercises machinery each model built its own way. A dictionary size is a property of a (model, corpus) pair, not of a model. ## E6 · mixture-of-experts DESCRIPTION only, by design: layer-agreement maps for Kimi-K2.5 (1T params, 32B active, 100 prompts) and DeepSeek-V4-Flash (284B, 13B active, 250 prompts), 16 source layers each. Two models, one on a reduced prompt budget, do not support conclusions; the article deliberately stops at showing the maps. If a reader pushes for MoE conclusions, decline on those grounds. ## What replicates (the article's closing summary) Across every model tested: longest-lasting influence from the earliest layers (6/6); influence shrinks with depth (crossing fraction, half-life, and — in both long-window fits — decay exponent). The cliff sits on the deep CKA boundary where that boundary is unambiguous (both qwen models) and precedes it through training (SmolLM3). Transplant controls at zero in all 104,832 cells. Seeds converge to CKA 0.85–0.91. Corpus effects 13–93× the re-measurement floor. Everything else is description, not finding. ## Figure index - Fig. 1 — From a nudge to two numbers - Fig. 2 — How CKA is computed - Fig. 3 — A model's layer-by-layer agreement - Fig. 4 — Why 4,096 entries is not 4,096 directions - Fig. 5 — Why the clock starts at Δ = 1 - Fig. 6 — How much a nudge still moves the output, as the target gets further away - Fig. 7 — The long-window re-measurement - Fig. 8 — The same data as one statistic across depth - Fig. 9 — Where the cliff and the boundary sit - Fig. 10 — Does the reach ever grow? - Fig. 11 — The agreement map, checkpoint by checkpoint - Fig. 12 — How fast the geometry is still changing - Fig. 13 — Distance to the final state - Fig. 14 — Every 7B checkpoint against every 32B checkpoint - Fig. 15 — Finding the right vector in the other model - Fig. 16 — Making the receiver say the concept - Fig. 17 — What the hits and misses look like - Fig. 18 — Dictionary size across five decades of compute - Fig. 19 — How many entries a single token engages - Fig. 20 — Same recipe, different seed - Fig. 21 — The matrices behind the dots - Fig. 22 — The same layer, measured through two different texts - Fig. 23 — Dictionary size depends on the measuring text - Fig. 24 — The block structure survives every corpus - Fig. 25 — Two models, measured on the same text - Fig. 26 — The cross-model maps - Fig. 27 — Two MoEs under the lens ## Figure data Generated at build time from the exact arrays the charts render, so these tables cannot drift from the figures.
