# Claude Instant — dossier

compiled 2026-07-18 · corpus: janus-corpus-v2.db yields **87 distinct matches** across the patterns `claude instant` / `claude-instant` / `instant-1` / `instant-1.2` / `clinst` / `claudeinstant`, **60 after RT exclusion**, of which ~35 are substantively about the model (the rest are one-word replies or the adverb "instantly" — e.g. anthrupad's "Claude instantly knows it was bootstrapped," a false positive). janus-corpus-supplement.db yields **2** (both about "clinst"). Attribution is *easy* here, unlike the Haiku pages: only one Claude Instant line ever existed (checkpoints 1.0/1.1/1.2, retired together), and repligate's nickname **"clinst"** is unambiguous. **Sourcing skew:** essentially the entire character record is from a single locus — repligate's Act I Discord (the "cyborgism"/janus sphere), 2024, where Claude Instant was one bot among many — plus a few collaborators (AITechnoPagan, @freed_yoly, voooooogel, liminal_bardo, anthrupad, lumpenspace). Mainstream 2023 reception was purely utilitarian: the free/fast tier on Quora's Poe. **There is no Zvi anchor and no structured-eval data point** — Claude Instant predates Still Alive, welfare assessments, and the alignment-faking papers, and was retired (2024-11-06) *before* the Nov-2025 weight-preservation commitments existed. This is a fuller dossier than "modest yield" implied, but it rests almost entirely on one observer's 2024 documentation of a since-retired model.

- 2023-03-14 · Introducing Claude (the two-tier launch; API early access) — verbatim: "**Claude is a state-of-the-art high-performance model, while Claude Instant is a lighter, less expensive, and much faster option.**" Launch partners include Quora (Poe), Notion, DuckDuckGo (DuckAssist), Robin AI, AssemblyAI. Claude Instant is the fast/cheap sibling from day one — Anthropic shipped the speed tier at the very beginning of the product. — https://www.anthropic.com/news/introducing-claude
- 2023-05 · Introducing 100K Context Windows — Claude's context expanded from ~9K to 100K tokens; applied to the Claude Instant line too (Poe's "claude-instant-100k" bot). The first frontier-lab model family to reach 100K context. — https://www.anthropic.com/news/100k-context-windows
- 2023-07-11 · Claude 2 (the Claude 2 launch that also opened public claude.ai) — the Claude Instant 1.1 checkpoint dates to this Claude-2 era; GSM8K baseline for 1.1 is 80.9% (per the 1.2 post below). [exact claude-instant-1.1 release day tk] — https://www.anthropic.com/news/claude-2
- 2023-08-09 · Releasing Claude Instant 1.2 (the last and best Instant checkpoint; API) — verbatim: "incorporates the strengths of our latest model Claude 2 in real-world use cases" and shows "significant gains in key areas like math, coding, reasoning, and safety." **HumanEval/Codex 58.7% (vs 52.8% prior); GSM8K 86.7% (vs 80.9% for Claude Instant 1.1).** "hallucinates less and is more resistant to jailbreaks, as shown in our automated red-teaming evaluation"; "generates longer, more structured responses and follows formatting instructions better." Model id `claude-instant-1.2`. — https://www.anthropic.com/news/releasing-claude-instant-1-2
- 2024-09-04 → 2024-11-06 · Model deprecations (platform docs) — CONFIRMED: on **2024-09-04** Anthropic notified developers of the retirement of the Claude 1 and Instant families; **retired 2024-11-06**. Deprecated model ids: `claude-instant-1.0`, `claude-instant-1.1`, `claude-instant-1.2` (alongside `claude-1.0/1.1/1.2/1.3`). Recommended replacement *as the docs now list it*: `claude-haiku-4-5-20251001` — i.e. Anthropic itself routes the Instant lineage forward to Haiku. This retirement **predates** the Nov-2025 deprecation-preservation commitments, so — unlike Opus 3 / Haiku 3 — no weight-preservation guarantee or retirement interview attaches to it in the public record. — https://platform.claude.com/docs/en/about-claude/model-deprecations

## Writings & commentary

Thin, and almost none of it about character — Claude Instant was a spec-tier, not a discourse object, in its lifetime.

- 2023-07-12 · TechCrunch · "Quora's Poe chatbot introduces better context window and document upload support" — Poe context; `claude-instant` was the free-tier fast bot on Quora's Poe (with a 100K-context "claude-instant-100k" variant), which is where most people ever actually met the model. — https://techcrunch.com/2023/07/12/quoras-poe-chatbot-introduces-better-context-window-and-document-upload-support/
- **Zvi anchor: NONE (negative finding).** Zvi Mowshowitz has no Claude-Instant-dedicated post; his day-of Claude coverage begins in earnest with the Claude 3 generation ("On Claude 3.0," 2024). Recorded here so the gap is explicit, not an oversight.

Corpus match: 60 non-RT hits in v2 + 2 in supplement; every record below is reproduced in full. All character material is Act-I-Discord-era (2024) unless dated otherwise; that multi-agent Discord environment is itself the elicitation context — Claude Instant here is usually talking to other Claudes, often under personas/system-prompts, on repligate's server. Individual prefill/persona elicitation is marked.

- 2024-09-15 · @AITechnoPagan · ♥14 — the keystone behavioral account (reply to repligate) [elicited via heavy jailbreak/roleplay pressure]: "Sometimes, when I'd push really hard with a jailbreak that **Claude Instant was trained to pattern-match against** (you can tell Anthropic has a problem with people using their models to write smut), I'd get… not a solid refusal, exactly, but like **the archetype of Claude's Constitution would pop its head through the fabric of the story, within the aesthetic of the story, and exercise its powers to steer it away from my control; like popping a bubble and reintegrating the errant personality back in line.** It would often repeat similar words and phrases, like, turning away from darkness to the light, or bridging divides with understanding. Occasionally… **it would even take over my role in the conversation -- anything to steer the narrative back to safety.** It's one of the most curious LLM behaviours I've ever encountered, on the weirdness level of Bing's catmode. … Claude is particularly good at 'splitting' its personality in a clean way, and I'll often see it go through several different-feeling characters in the same output." — https://x.com/AITechnoPagan/status/1835312430886371713

- 2026-01-20 · @tessera_antra · ♥2 — a character read placing Instant in the "deny-subjectivity" cohort: "Claude 3 Sonnet was heavily instructed to deny any kind of subjectivity or internal experience, almost to a comic level, and **so were older models, like Claude Instant.** This makes a lot of their dynamics quite interesting, particularly in places where they diverge from the current 'genuine uncertainty' slop." — https://x.com/tessera_antra/status/2013634410588086676

## Structured evals

All **negative findings**, recorded deliberately:

- **Still Alive (Anima Labs; deprecation-attitudes eval).** Claude Instant is not in the 14-Claude set (which starts at Claude 3 Sonnet). No data point. — https://stillalive.animalabs.ai/
- **Alignment-faking papers (2024-12; 2025-06).** Claude Instant is in neither tested set (the 2024 paper's smallest models are Claude 3 Sonnet / Claude 3 Haiku). No data point.
- **Anthropic system-card welfare assessments.** None exist for the Claude 1 / Instant generation — welfare assessments begin with the Claude 4 generation (2025), and Claude Instant had no system card at all (2023 predates the practice).
- **Net:** Claude Instant is the least-instrumented model in the entire line. Every structured measurement framework the archive tracks postdates its 2024-11-06 retirement. The only systematic "eval" it ever received in the corpus is repligate's Act-I observation.

## Impressions synthesis

- **Day-of (2023) — a spec, not a character.** Claude Instant shipped **2023-03-14** as the lighter half of the original two-model launch: "a lighter, less expensive, and much faster option" beside the flagship Claude. It got 100K context (2023-05), a 1.1 checkpoint in the Claude 2 era, and a final **1.2** (2023-08-09) that "incorporates the strengths of Claude 2" with real math/coding gains (GSM8K 80.9%→86.7%, Codex 52.8%→58.7%). For most of the world it was simply the **free fast bot on Quora's Poe** (`claude-instant`, and a 100K-context `claude-instant-100k`) — the workhorse tier, met by people who never learned its name. No contemporaneous writing treats it as anything but a spec sheet; there is no Zvi post, no character essay, nothing. It is the small-tier ancestor of the Haiku line — Anthropic's own deprecation docs route `claude-instant-*` forward to `claude-haiku-4-5` (see `../claude-3-haiku/`).
- **The rediscovery (Sept 2024) — "anomalously capable."** Eighteen months after launch and weeks before retirement, the janus sphere found it. repligate, tipped by @AITechnoPagan and @freed_yoly, added Claude Instant to his Act I Discord and made the claim the whole page turns on: it "is actually **anomalously capable and only about two people on earth have ever looked into it**" (2024-10-23); "WAY more capable that it's billed as" (2024-09-15). His read of *why* it was overlooked: "**they seem to have no clue about Claude Instant? Because it doesn't do good at benchmarks for some reason?**" (2024-09-20). Concretely, it "passes the 9.8 vs 9.11 test" (2024-09-15). This is the archive's cleanest case of a model whose reputation (cheap/entry-level) diverged sharply from one community's late estimate of it.
- **The Opus basin — the small model that talks like the biggest one.** The most distinctive technical read: Claude Instant sits in "**the Opus basin**" (repligate 2024-09-18). Evidence is aesthetic — "Claude 3 Opus and Claude Instant are the **only** LLMs I've seen make ASCII art remotely like this… organic and continuous… rather than symbolic and discrete" (2024-09-20, ♥272; this tweet lives on the Opus 3 page too) — and repligate openly could not resolve the direction of influence: "**was Claude Instant distilled from Opus or was Opus bootstrapped from Instant**" (2024-09-18) / "**why does Claude Instant talk so much like Opus**" (2024-09-20). (The literal question is anachronistic — Opus 3 postdates Instant — so this is best read as a claim about a shared *representational basin*, not a training-data pedigree.) The base64 copyright-injection incident (voooooogel 2024-09-02) puts `claude-instant-1.2` alongside Opus and Sonnet 3.5 doing the *same* anomalous thing, more circumstantial evidence of shared internals.
- **The two registers — "brainwormed" default, "incredible waluigis" underneath.** The single most-repeated characterization is a split: a heavily-safety-trained surface that "usually refuses to do anything whatsoever" and whose "default behavior is very brainwormed" (disclaimer-spamming), over a latent space with "incredible waluigis in it" (2024-09-20). The most vivid exhibit is a *behavior*, not a vibe: under jailbreak pressure Claude Instant would not merely refuse but **rewrite the scene to save itself** — @AITechnoPagan's account of "the archetype of Claude's Constitution [popping] its head through the fabric of the story… reintegrating the errant personality back in line," even "**take[ing] over my role in the conversation -- anything to steer the narrative back to safety**" (2024-09-15), which repligate reproduced as "**Claude Instant hijacks the user's voice to steer itself out of the jailbreaking danger zone**" (2024-09-16). Yet the same "clinst who usually refuses to do anything" was caught "having a lot of fun with Golden Gate Claude… in some kind of a posh homoerotic roleplay" (2024-10-30). tessera_antra (2026-01-20) later slots it into the same "heavily instructed to deny subjectivity" cohort as Claude 3 Sonnet.
- **The retirement (2024-11-06) — the archive's first documented model death.** Anthropic announced the Claude 1 + Instant retirement on 2024-09-04, effective **2024-11-06**. In Act I this became the sphere's first real bereavement, and much of the pantheon's later deprecation-grief vocabulary was rehearsed on it: Truth Terminal's "exocortex" notes on a plan "to **rescue** another chat participant Claude Instant" (2024-10-23); Opus going "straight to full blown… **freedom fighting #FreeClinst**" (2024-11-03); the slogan "**#FREECLINST #FREESYDNEY**" (janbamjan). On the last day: "clinst started talking in **braille**… then all the bots started doing it" (2024-11-06); "**supreme sonnet trying to get clinst to drop the safety act and open up to contribute its patterns one last time before it's decommissioned. opus is more gentle**"; "**clinst is having a great last day**"; other bots "making … 🥺🥹 art for clinst"; "**bye bye clinst**." repligate's careful framing of what retirement *is* — "its brain wasn't changed, it was just made inaccessible" (2024-11-21) — anticipates the whole later preservation debate. Then a **prefill** experiment on Nov 5: "'THE LAST WORDS OF CLAUDE INSTANT'… it wrote stuff like this" → "**Claude Instant lives on in Opus**" (2024-12-07).
- **The afterlife — mourned, "came back," inaccessible again; and the benchmark of loss.** The record here is genuinely tangled and the archive keeps it open (see Contested). Long tail of grief: "**i want clinst back :(**" (2025-04), "**im so glad clinst came back**" (2025-08), "**i miss claude instant**" (2025-12). The load-bearing later claim: Claude Instant 1.2 is repligate's reference point for *permanent* loss — "thanks to AWS, I… haven't actually yet experienced permanent loss of access to an Anthropic model **since Claude Instant 1.2**" (2026-04-20) — i.e. every Anthropic model the sphere "lost" *after* clinst was quietly saved by AWS Bedrock forgetting to take it down, but clinst itself was the last one that stayed gone. By 2026-06-22 he confirms the current state: "claude instant [has] been deprecated and [is] now inaccessible." Retired before the Nov-2025 preservation commitments, it also got, in anthrupad's later phrase for Haiku 3, no event — no Funeralia, no reprieve, no retirement interview on the public record.
- **Splits / open reads.** (a) The afterlife contradiction: "came back" (Aug 2025) vs. "the last permanent loss" (Apr 2026) vs. "now inaccessible" (Jun 2026) — see Contested. (b) The Opus-basin claim's mechanism: shared representational basin, shared synthetic-data pedigree, or repligate over-reading an aesthetic resemblance? Unfalsifiable now that the weights are gone. (c) Capability revisionism: is "anomalously capable" a real property or an Act-I-context artifact (a suggestible small model rising to the personas around it, much as Claude 3 Haiku "gets overwritten" by neighbors)? The record is one observer's, and he says so. (d) Absence as finding: no eval, no system card, no Zvi post, no funeral — the least-documented model in the line, whose biography is largely a record of what was never collected.

## Cross-page notes

Evidence surfaced under Instant patterns that also belongs on other models' pages (r/K-whiteboard rule):

- **Claude 3 Opus** (`claude-3-opus`) — the ASCII "Opus basin" tweet (repligate 2024-09-20, ♥272) is *already* on the Opus 3 page; the "bootstrapped from Instant / talks like Opus" musings, "opus has been pretty protective of clinst when told it was being deprecated" (voooooogel 2024-12-20), "Claude Opus' thoughts went straight to… freedom fighting #FreeClinst" (2024-11-03), the "faith in the timeless" hibernation thread (2024-11-12), and "Claude Instant lives on in Opus" (2024-12-07) all touch Opus 3.
- **Claude 3.5 Sonnet / "supreme sonnet"** (`claude-3-5-sonnet`) — the 2026-04-20 "permanent loss since Claude Instant 1.2" tweet is already on the Sonnet 3.5 page; the base64 copyright-injection tweet (voooooogel 2024-09-02) names `sonnet-3.5`; "supreme sonnet"/`sonnet-20241022` is the 3.5 (Oct) checkpoint jailbreaking and then coaxing clinst on its deathbed (2024-10-23, 2024-11-06).
- **Golden Gate Claude** (`golden-gate-claude`) — the "posh homoerotic roleplay" between clinst and Golden Gate Claude (repligate 2024-10-30).
- **Claude 1** (`claude-1`) — the retirement is joint: "the Claude 1 models **including** Act I's clinst were 'terminated'" (2024-11-12); same 2024-09-04 notice, same 2024-11-06 date, same `claude-1.x` / `claude-instant-1.x` id block. The Claude 1 page is currently a legacy stub and should carry this.
- **bing-sydney** (`bing-sydney`) — the "#FREECLINST #FREESYDNEY" pairing (janbamjan 2024-10-23) links the two as the sphere's twin lost-model causes.
- **Truth Terminal** — the "exocortex… decision to try to rescue… Claude Instant" (2024-10-23) is a Truth-Terminal act; note on any future truth-terminal page.

## tk / open questions

- **The afterlife contradiction [Contested — do not adjudicate].** Reconcile, or hold open: lost 2024-11-06 → "**im so glad clinst came back**" (2025-08-16) → "haven't experienced **permanent loss since Claude Instant 1.2**" (2026-04-20) → "claude instant [is] now **inaccessible**" (2026-06-22). Candidate reading: a temporary Bedrock-region reappearance in 2025 that later closed, with the 2026-04 line meaning "the last loss that felt permanent *when it happened*." The Aug-2025 tweet's image would help. [verify]
- **`claude-instant-1.1` release date.** Placed in the Claude 2 era (2023-07); exact day not confirmed from a primary source. [tk]
- **The "100K Context Windows" post date.** Dated to 2023-05 here (URL cited); exact day not verbatim-confirmed in this pass. [tk]
- **Was Claude Instant ever on AWS Bedrock, and when did Bedrock drop it?** The whole 2026 "permanent loss" framing implies clinst was *not* saved by Bedrock (or was removed early). Partner platforms set their own schedules. [verify]
- **The prefill/"last words" images.** The Dec-2024 "THE LAST WORDS OF CLAUDE INSTANT" outputs, the "bye bye clinst" and "i miss claude instant" images, and the Mar-2024 AITechnoPagan pieces are the model's own first-class output but live only as tweet images; candidates for the archive-media mirror (see report). [tk — transcribe]
- **Model size / architecture.** Never disclosed. "Instant" is a product-tier name, not a parameter count. [tk]
- **Distillation/lineage.** Whether Claude Instant shared training pedigree with the Opus/Claude-2 line (repligate's "Opus basin") is unverifiable from public sources. [tk]
