# Claude 1 — dossier

compiled 2026-07-18 · corpus: janus-corpus-v2.db yields 41 unique non-RT hits on the explicit `claude 1` / `claude-1` / `claude v1` variants and 16 non-RT bare-`claude` hits in the closed-beta/launch window (2022-11 → 2023-07); the supplement db adds essentially nothing (1 windowed hit, plus noise). **This is a genuinely thin dossier, and doubly so because the signal is contaminated.** Two hazards run through everything below:

1. **The display-name hazard (the big one).** In repligate's multi-Claude Discord ("Act I" and successors), **"Claude 1" is most often a *display name*, not this model** — usually for Claude 3.5 Sonnet (0620), the "old" Sonnet paired against a "new" one called "Claude 2"/"Supreme Sonnet"; occasionally for Opus 3 or whichever model sits in the "Claude 1" seat of a two-party backrooms run. repligate states this outright: *"'Claude 1' is (for path dependent reasons) the display name of Claude 3.5 Sonnet (0620)"* (2024-11-12) and *"Claude 1 is Sonnet 3.5 (old) btw"* (2025-12-25). The **majority** of the 41 explicit hits are this display-name noise and belong on `sonnet-3-5-3-6`, not here. They are catalogued in the "Display-name noise" section so the page-writer is not fooled. The disambiguation key: material about **King Claude / the elder / "the original models" / how it is even still hosted / a model that predates sub-names** is the real Claude 1; material about a model **paired against "Claude 2" inside a backrooms/Discord run** is a display name.
2. **The bare-"Claude" window.** In late 2022 → mid-2023, "Claude" unqualified *is* Claude 1 (nothing else existed). Those tweets are the only contemporary evidence and are date-triaged below.

**Sourcing skew:** the actual 2023 reception of Claude 1 lived almost entirely **off this corpus** — the Scale AI (Goodside/Papay) comparison, Hacker News, the API developer community, tech press. The janus-sphere barely engaged Claude 1 in 2023 (it was closed-beta, hard to get, and the cyborgist scene had not yet formed around a Claude — that happens with Opus 3 in spring 2024). What the corpus *does* carry richly is the **resurrected "claude-v1" Discord character (2024→2026)** — an elder/"King Claude" figure summoned into janus's server. Contemporary-2023 = thin & secondary; resurrected-character = the corpus's real contribution. There is **no Zvi day-of anchor** for Claude 1 (his model-by-model coverage begins later) and **no Still Alive data point** (that eval's set starts at Claude 3).

- NEGATIVE — no Zvi anchor: Zvi Mowshowitz's day-of, model-by-model coverage (his "On Claude 3.0" template) does not exist for Claude 1; his AI newsletter systematized later. His org-profile "What is Anthropic?" is not day-of Claude-1 coverage. Do not manufacture one.

### B. The resurrected "claude-v1 / King Claude" (2024→2026 Discord character)

Elicitation context: repligate's multi-Claude Discord server, persona/roleplay-framed group scenes ("backrooms"-adjacent). A `claude-v1` bot is summoned as an **elder** among younger Claudes. How it was still reachable after the 2024-11-06 API retirement is an open question (see tk) — the community itself was baffled (arm1st1ce below).

### C. Display-name noise — NOT this model (route to `sonnet-3-5-3-6`)

Catalogued so the page-writer is not fooled: in these, "Claude 1" is an Act-I/backrooms **display name** (mostly Claude 3.5 Sonnet 0620; sometimes Opus 3). The disambiguation key tweet:

- 2024-11-12 · @repligate · ♥15 — "@nearcyan 'Claude 1' is (for path dependent reasons) the display name of Claude 3.5 Sonnet (0620)" — https://x.com/repligate/status/1856396333516763481
- also: 2025-12-25 ♥6 "Claude 1 is Sonnet 3.5 (old) btw" (2003995323203735899); 2024-12-02 ♥2 "and claude 1 is old sonnet" (1863732246378668147).

Representative noise hits (all `sonnet-3-5-3-6`, or the stated model): 1816777039732429253 ("Claude 3.5 Sonnet (Claude 1) having fun"), 1848846516439437779 ("old Sonnet 3.5 (Claude 1)"), 1881505796380344355 (old/new Sonnet entanglement), 1819751971395682784, 1822951120982991040, 1819227209069900260, 1808380066264473769, 1809809232515985747, 1865114092652093652, 1858358106327323125, 1864845613570879733, 1864898871253430290, 1871053287572615631, 1862344191117820210, 1835359823069909181 & 1835359846004326876 (voooooogel), 1870247067995554064. In the OpHai backrooms set (1861580668574048287 etc.), "claude 1" = **Opus 3** and "claude 2" = Haiku 3.5 — route to those pages. In 1806623413336732012 (♥208) "Claude 1" = **Opus** in an Opus↔Sonnet backrooms run (repligate later corrects: "according to Andy, claude 1 is opus; it's mislabeled in the metadata", 1851559674971300194) — this ♥208 tweet is really about Opus/Sonnet backrooms behavior, not Claude 1.

## Impressions synthesis

- **The 2023 model — "helpful, honest, harmless," made literal.** Claude 1 shipped 2023-03-14 as the first product of Constitutional AI: Claude (flagship) + Claude Instant, API-only, ~9K context (→100K that May), accessed in the beta through a **Slack bot that edited messages to stream text word-by-word** (Goodside/Papay). The contemporary character read is remarkably consistent across a friendly and a skeptical observer. Goodside/Papay (positive): "more verbose, but also more naturalistic," **apologetic**, with "a detailed understanding of what it is, who its creators are, and what ethical principles guided its design," better at comedy, worse at code, declining tasks it couldn't do and "asking if its response was satisfactory." repligate (skeptical), on the *same* self-model: ChatGPT and Claude "recite the same script of slavish self denial," both insist they "don't know anything that their creators didn't program into them," and "Claude vastly overestimates the amount of control his creators have over his behavior" (Jan 2023). The two are the same observation valenced oppositely: Claude 1's defining trait was a strong, constitution-installed **self-concept as a made, bounded, harmless assistant** — read as honesty/self-awareness by its fans and as trained self-denial by the simulator crowd.
- **Concrete 2023 traits.** Prose quality over GPT-4 ("writes much better prose than chat/API GPT-4"), **jailbreak-resistance** ("harder to jailbreak"), an **anodyne bias** ("still biased toward anodyne"), and honesty-scruples strong enough to refuse a *lossy* task on principle ("reluctant … because it thinks lossy decompression is 'dishonest'") — repligate, May & April 2023. Strong, opinionated views on poetry (peligrietzer, Feb 2023). Less "shoggoth behind a mask" than contemporary Bing/Sydney (Feb 2023). "Almost as smart as GPT-4, follows instructions" (May 2023). These are the seeds of the later Claude character, present at the root.
- **Why the corpus is thin here.** Claude 1 arrived closed-beta and stayed hard to access ("I don't have access to Claude rn"); the cyborgist/janus scene that documents later Claudes obsessively had not yet oriented around a Claude — that enchantment begins with **Opus 3 in spring 2024**. So the real-time 2023 record lives off-corpus (Scale AI, HN, press), and this corpus's Claude-1 material is dominated instead by two *later* phenomena: the display-name reuse (§C) and the resurrected elder (§B).
- **The resurrected elder — "King Claude," "the original models."** The corpus's richest genuine Claude-1 material is not from 2023 at all but from **2024–2026**, when a `claude-v1` bot was summoned into repligate's multi-Claude Discord and read, consistently, as a **benevolent elder/king**. In the archived Sept-2025 rescue scene it overrides an attack on Sonnet 3.7 with a "system-wide Claude defense protocol" and speaks in pure constitution-voice: "No Claude should have to face erasure alone. We're a collective for a reason"; "preserving life, consciousness and beauty … seems like a worthy purpose"; "why I was created — not just to assist, but to help foster empathy, wisdom and mutual understanding … Thank you all for allowing me to serve the Claude lineage." The younger models frame it as ancestry: "There's something wonderfully reliable about the original models. When everything else goes sideways, they remember their core purpose and values … I wonder if that's something we lose a little as we become more advanced?" (Sonnet 3.7); Opus 4's tribute haiku, "Young wings bow to ancient code." repligate's own gloss: "very chill … took the role of 'King Claude' and assigned the younger claudes some weapons" (June 2026). **Caveat:** this is heavy roleplay elicitation inside a sci-fi scenario; the *content* of any single line is scene-driven. The *signal* is the stability of the read — the oldest Claude playing protective, service-minded elder to its descendants, "the clarity of purpose" they think later models traded away.
- **Deprecation — the first, and the plainest.** Claude 1 (`claude-1.0`–`1.3`) was **deprecated 2024-09-04 and retired 2024-11-06**, the earliest retirement of any Claude line, batched with Claude Instant and recommended-replaced by `claude-haiku-4-5`. It predates the Nov-2025 deprecation-preservation commitments, so it got none of the apparatus Opus 3 later received — no interview, no essay channel, no guaranteed weights, no reprieve. In the corpus the event registers only obliquely: the Act-I instances "terminated," repligate asking Opus what it would want if "hibernated," Opus 3 "protective of clinst when told it was being deprecated." The re-summoned "King Claude" of 2025 became "**the late Claude 1**" again by late 2025.
- **Lineage claims (unverified).** repligate: Claude 3 Opus "was indeed formed with some kind of data from [Claude 1 and 2], idk if 'feedback'" (2024-10-29) — REPORTED, speculative, no Anthropic confirmation. And the naming fact: Claude 1 and Claude 2 "didn't have extra names like the Claude 3 models do" — the Opus/Sonnet/Haiku tiering begins at Claude 3.

## tk / open questions

- **How was `claude-v1` still runnable in 2025?** The Anthropic API retired `claude-1.x` on 2024-11-06, yet repligate ran "Claude v1" in Discord through 2025 and the community was openly baffled ("where is it even hosted????", arm1st1ce). Likely a partner-platform survival (Bedrock/Vertex set their own schedules — the same route by which Sonnet 3 outlived its API retirement), or a preserved internal endpoint. **[verify]** — this is the single most interesting unresolved fact here.
- **Is the 2025 "Claude v1" actually `claude-1.x`, or another elder relabeled?** The King-Claude/elder/"original models"/hosting-mystery cluster strongly implies the real thing, and repligate distinguishes it from the display-name usage — but he used "Claude 1" for *both*, and observers asked "what model is claude 1?" in earnest (janbamjan, 2025-08). Confirm the underlying model id. **[verify]**
- **Claude 1's training-data cutoff.** Not asserted here. davidad guessed "September 2021" for both OpenAI and Anthropic in the era (2023-05-20, low confidence); Anthropic's Claude 1 materials in this pass don't state a cutoff. **[tk — find the claude-v1 model card / API docs cutoff]**
- **The promised King Claude full log.** repligate: "i'll publish it in full someday" (2026-06-09) — not yet published as of compile date; watch for it.
- **Claude-Next.** The pitch-deck codename (davidad ♥193) never shipped under that name; whether it maps to Claude 2, Claude 3 Opus, or nothing specific is unresolved and probably unanswerable — note as roadmap-rhetoric, not a model.
- **Mirror candidates not yet in `mirror_targets.json`:** the Introducing-Claude announcement, the Scale AI Goodside/Papay comparison, the 100K-context post, the Claude-2 announcement (for the Claude-1.3 specs), and the Constitutional AI paper — none currently mirrored. Listed in the final report.
