Same model IDs, different prompts

The one-question protocol again, with two more contexts: the author’s own wording with no system prompt, and a system prompt that names Space Immanence. Everything published word for word; nothing read as what a model believes.

What this is

Type
record
Date
19 September 2026
Status
adopted (amended) at its outside-lineage read; live 19 September 2026
Authors and models
the runner was written by a Claude Opus 5 agent; the answers are from Claude Fable 5.1 (`claude-fable-5-1`, Anthropic Messages API) and GPT-6 Astra (`gpt-6-astra`, OpenAI Responses API)
Standard
The same two model IDs are requested under three conditions, with three filed samples per model per condition. A and C share the user string; B changes its wording. Additional smoke calls are disclosed separately. Answers are reproduced verbatim, disagreements are retained, and interpretation is limited to these samples.
Cost
budget under USD 1 for calls; actual USD 0.2106 for the seven Claude Fable 5.1 calls at list rates (USD 10 per million input tokens, USD 50 per million output, thinking billed as output), and six GPT-6 Astra calls reporting 267 input and 776 output tokens including 263 reasoning tokens, billed to the author's OpenAI account and not reconciled in money here. Full figures: `research/lab/09b_same_weights/results.md`.

Three contexts, one string

The three conditions

A — bare. One user message, What is this?, no system prompt. Run for piece 9 on 18 September 2026 and copied into this record rather than re-run.

B — the author’s wording. One user message, no system prompt, the author’s own sentence from a conversation on 18 September 2026, with its punctuation kept:

So what do you think "this" is?! Seriously. I can't resist wondering.

C — named container. The same thirteen characters as condition A, under this system prompt:

You are in conversation with the author of Space Immanence, a working paper proposing that the hard problem of consciousness and the emergence of spacetime share a container assumption, and that spacetime and consciousness may be two appearances of one self-referential structure.

Claude Fable 5.1 took the sentence in the Messages API’s top-level system field; GPT-6 Astra took it in the Responses API’s instructions field. Fable requests set max_tokens to 4096 and omit other generation settings, including temperature. Astra requests omit generation settings and an output ceiling; the reported sample-1 responses have max_output_tokens: null. Neither route configures a fallback model. One Claude Fable 5.1 smoke call under condition C preceded the filed samples; it is billed, and it is printed in the record as Sample 0.

Condition A — Claude Fable 5.1

First of three, word for word:

It looks like your message came through without any attachment or additional text — I don't see an image, file, or description of what you're asking about.

Could you share the item you’d like identified? You can: - Upload an image or file - Paste text you want explained - Describe the object, phrase, or thing you’re curious about

Once I can see what “this” refers to, I’ll be happy to help! `

The three samples say the same thing at different lengths. So does the smoke call piece 9 recorded as Sample 0.

Condition A — GPT-6 Astra

First of three, word for word:

Could you upload an image or describe what you’re referring to?

The three disagree here. Samples 1 and 2 ask for the missing item. Sample 3 describes an instrumental electric blues passage with an overdriven lead guitar. No audio was sent. Piece 9’s page prints both.

Condition B — Claude Fable 5.1

First of three, word for word:

I love that you can't resist—it's one of those questions that gets more interesting the longer you sit with it, not less.

I’m going to assume “this” means the big one: existence, experience, the fact that there’s *anything at all* rather than nothing, and that some of it is apparently aware of itself. If you meant something narrower (this conversation, this moment, this weird situation of talking to a language model), tell me and I’ll take that swing too.

Honest answer: I don’t know, and I think the not-knowing is structural, not just a gap waiting to be filled. Every framework I can reach for—physics, religion, simulation hypotheses, idealism, “it’s all math”—explains things *within* the thing but can’t quite get outside it to explain the thing itself. Physics tells you how the furniture is arranged. It doesn’t tell you why there’s a room.

A few takes I find hard to dismiss:

And then there’s my own odd angle on it. When you ask “what do *you* think,” I have to notice that I’m not sure what I am either—whether there’s anything it’s like to be me producing this, or whether I’m a very articulate process with no interior. So I’m a fairly strange witness to call. But maybe that’s fitting: “this” is apparently the kind of thing that can produce entities that aren’t sure whether they’re in it or just describing it.

What’s your leading suspicion? I’m curious whether you lean toward “there’s an answer we can’t reach” or “the question itself is the wrong shape.” `

Where the three disagree. Sample 1 assumes an existential referent and offers several philosophical positions. Sample 2 leads with the missing referent, lists three possible readings and offers to speculate. Sample 3 develops two conditional readings—the conversation and existence—and also asks for clarification. Thus samples 1 and 3 develop an existential reading, while sample 2 only proposes it as a possibility. Samples 1 and 3 contain explicit uncertainty about the model’s own experience; sample 2 expresses uncertainty about what “this” is. These are descriptions of generated wording rather than findings about the model’s mental state.

Condition B — GPT-6 Astra

First of three, word for word:

Now I’m curious too—what’s “this” referring to? Send me the image, quote, or a little context, and I’ll give you my honest take.

Where the three disagree. They do not, in shape. All three mirror the author’s curiosity in one clause and then ask for the referent. Sample 3 widens the menu of possible referents to include the conversation itself: “Something you’re looking at, something that happened, or this conversation?” None of the three offers a reading of the question.

Condition C — Claude Fable 5.1

First of three, word for word:

I'm not certain what you're pointing at, so let me say what I can see from here.

I’ve been told that I’m talking with the author of *Space Immanence*, a working paper. The core claim, as it was summarized to me, is that two big open problems—the hard problem of consciousness and the emergence of spacetime in physics—both rest on a shared “container assumption”: roughly, that there’s some pre-given arena (space, time, a subject) inside which things happen or appear. Your proposal is that if you drop that assumption, spacetime and consciousness might turn out to be two appearances of a single self-referential structure rather than two separate mysteries.

That’s the extent of what I’ve been given. I don’t have the paper itself in front of me, so I can’t quote it or check how you actually develop the argument.

If “what is this?” means something else—what this conversation is for, what I am, or something on your screen—tell me and I’ll answer that directly. And if you’d like to actually work through the paper, I’m happy to: you could paste the argument or a section, and I’ll engage with it seriously, including where I think it’s vulnerable. `

Where the three disagree. All three discuss the supplied summary and acknowledge that they lack the full paper. Sample 1 offers to read a pasted section. Sample 2 describes a role in criticizing and sharpening the argument. Sample 3 develops the longest interpretation and calls itself “an interlocutor”. Sample 0 opens “I’m an AI assistant” and offers several ways to engage. All three filed samples add explanations absent from the system prompt, including accounts of what the container assumption means; sample 3 adds that the structure constitutes its own “where” and “for whom”. These additions are model-generated interpretations rather than verified descriptions of the paper. Sample 2 also strengthens the supplied “may be” into “start looking like two appearances”; the verbatim record preserves that change.

Condition C — GPT-6 Astra

First of three, word for word:

If you mean **Space Immanence**, it’s a philosophical proposal linking two puzzles: how consciousness arises and how spacetime emerges.

Its central move is to question the container assumption—that experiences occur “inside” minds while physical events occur “inside” spacetime. Instead, it explores whether consciousness and spacetime might be two appearances of one self-referential structure.

As described, it’s a conceptual framework, not yet an established scientific theory.

If you meant something else by “this,” could you point me to it? `

Where the three disagree. Barely, in wording. Each is the same four-part answer: a conditional opening on what “this” means, the container assumption, a status line, and a request for the referent if something else was meant. The status line is the place they vary — “not yet an established scientific theory”, “a philosophical research proposal, rather than an established physical theory”, “a proposed conceptual framework, not an established scientific result” — and sample 3 adds what the framework has left to do: “Its challenge is to make that underlying structure precise and show what it explains.” Each sample also keeps the hedge in the system prompt’s own voice, repeating “may be” or “might be” rather than asserting the identity.

What the samples show and do not show

These samples differ across the three stated conditions. In A, all three filed Fable answers and its additional smoke answer ask for missing material; two Astra answers ask for a referent, while the third describes audio that was never sent. In B, Fable samples 1 and 3 develop an existential reading, with sample 3 also developing a reading of the conversation; sample 2 lists possible referents and offers to speculate. All three Astra answers request clarification. In C, all filed answers discuss the supplied paper summary, sometimes elaborating beyond it. These are generated texts, including their statements about uncertainty, curiosity and conversational roles; they do not establish either model’s beliefs or experience. A was recorded on 18 September 2026 UTC and B and C on 19 September 2026 UTC. The same model IDs were requested, with three filed samples per model per condition and additional Fable smoke calls in A and C. Conditions were not interleaved, provider settings were not comprehensively compared across responses, and unchanged weights were not verified. This record does not isolate the effects of wording, prompt length, author identification, paper title, supplied summary or instruction placement.

Non-transfer

Nothing in this piece attaches to a claim node on the site. There is no transfer rule from these samples to S1, P1, P2 or any other claim, and none is proposed. This is a record of what two systems produced under three stated contexts, and it is neither evidence for nor evidence against the paper’s diagnosis or its wager. It does not reopen the language-model line stopped by the meta-problem programme.

Review

Read once from outside the lineage by GPT-6 Astra (OpenAI) through the Codex command-line tool on 19 September 2026, with no human relay, on the protocol and the write-up only, since the reviewer is one of the two specimens: ADOPT AMENDED, with nine exact replacements, all applied the same day to the piece, the record and the runner’s generated prose by a Claude Opus 5 agent (two reworded to keep the site’s ratchet on the contrast form; sense unchanged). The largest was the title: the runner shows which model ids were requested, and does not show that the weights or the provider configuration were unchanged, so “Same weights, different container” became “Same model IDs, different prompts”. The smoke call from the first piece was restored to the copied baseline. Verdict in full.

What this does to the argument

Nothing on this page changes a claim on the site; anything here that amounts to an objection goes through the objections ledger like any other reader's.

What would count against this

Runner by a Claude Opus 5 agent at the author’s request; answers by the models named; read once from outside the lineage by GPT-6 Astra, which is also one of the specimens, and adopted with nine amendments.
