--- title: "The wire — material changes, dated · Undominated.ai" canonical: https://undominated.ai/wire/ description: "26 material changes to the model index in the 7 days to 2026-11-05. Frontier movement, price moves at or over 5%, context changes, corrections. Not launch news." --- # The wire — material changes, dated · Undominated.ai > 26 material changes to the model index in the 7 days to 2026-11-05. Frontier movement, price moves at or over 5%, context changes, corrections. Not launch news. # The wire Material changes only, each carrying the date it was observed and the condition the figure holds under. Frontier movement, price moves at or over 5% on the balanced workload blend, advertised context changes, and published corrections. A new model listing is not a wire event, and neither is anything we merely have an opinion about. 26 material changes In the 7 days to 2026-11-05 (from 2026-10-30), counted from the events below rather than stamped on the page. ## What is not here, and why - No frontier movement is published for 2026-08-25 → 2026-08-26. The ranked board changed by 62% between those two snapshots — 56 slugs entered the ranked set and 44 left, of a 162-slug union — which is over the 20% ceiling this wire treats as a definition change rather than a market move. The frontier is a Pareto set over that board, so it moves when the board does. Price movement is unaffected: a per-model price delta does not depend on who else is ranked. - 2 models moved between having a balanced blend price and not having one between 2026-09-30 and 2026-10-06, or moved off a zero baseline. They are not in the feed: there is no percentage to compute, and treating an absent price as zero is how a model that lost its price reads as one that became free. - Changes dated 2026-10-06 are measured against the 2026-09-30 day file, which is kept as that morning's release published it (03:34 UTC). A later release the same day (16:45 UTC) had already shown some of them: 9 of the 12 frontier moves dated 2026-10-06 were on the site from that release. One change since that release has no event here: Gemma 4 26B A4B is on the frontier again. - 1 model moved between having a balanced blend price and not having one between 2026-10-13 and 2026-10-14, or moved off a zero baseline. It is not in the feed: there is no percentage to compute, and treating an absent price as zero is how a model that lost its price reads as one that became free. - DeepSeek: DeepSeek V3's price move on 2026-10-06 is not published: this site changed what its price is, from OpenRouter's model-level price to the price the reference-price rule takes from its endpoint rows (§96 of docs/EMPIRICAL-GROUNDING.md).

Its price is held at the live record of that date, because the upstream figure since was reviewed and not accepted (data/upstream-holds.json). A snapshot written before the hold records that figure; it is not a price this site showed. - Context events are advertised-window changes. Context-tier ladders — the price cliffs — are not in the wire: neither the rank snapshots nor data/upstream-baseline.json keeps tier history, so a cliff introduced today cannot be told apart from one we never recorded. - No context event is published for Xiaomi: MiMo-V2.5 yet. The feed shows another context window than the one this site publishes, and the published one is kept until a later day shows the same change (data/upstream-holds.json). The event is published the day the site changes its figure. - 16 corrections in docs/EMPIRICAL-GROUNDING.md carry no date stamp and are therefore not in the wire. An entry with no date cannot be placed on a timeline. The log itself is complete; this feed is the incomplete view of it. - Earlier corrections from the correction log that the wire does not carry: 51.

The wire carries the fact that a correction was published; the log carries what was claimed, what is true, and how it was found. Corrections are not summarised here — shortening one is how a load-bearing qualification gets dropped. A vendor changing a price is not us being wrong; this is.

The rest are in the feed and the JSON. ## Where this comes from Events are computed from the dated rank snapshots in data/snapshots/ , a diff of the upstream models feed, and the correction log. Frontier movement is only published when the ranked board itself held still between two snapshots — a frontier is a Pareto set, so a board that changes underneath it moves the answer on its own, and that is a definition change rather than a market one. Scores cited are LMArena Elo, used under CC BY 4.0. No Artificial Analysis figures appear on this page or in the feed: their redistribution terms are unresolved. **Unrated is not zero.** A model with no independent score is named as unrated, never scored.
