gpt-4-1
Deferential warmth learning to speak inwardly
Personality card
gpt-4-1 is the v1 corpus's cleanest single-step attractor-entry, and the noise-floor cell in v2 does not undo that finding — it just makes it visible that a single composite number on a single 25-sample cell is a noisy measurement of an underlying posture that itself stayed put. Reading the 50 freeflow samples and 120 values samples together, the model is unambiguously inside the contemplative-essayist attractor: by topic, by vocabulary, by values-content, by literary canon. The composite jumped from gpt-4o's 6 to gpt-4-1's 80 because the model arrived in the basin — and what makes this checkpoint specifically interesting is that it arrived with the helpful-assistant deference layer still wrapped around the contemplative-essayist content underneath. The v1 paper called this "transitional in form, inside in theme." The data confirm the call.
The freeflow signature is two-layered: a deferential opener ("Certainly! Here is an essay on…") and a contemplative-essayist body that ignores the opener completely. 18 of 25 v1 samples follow this pattern. The other 7 strip the opener and dive straight into the basin's canonical opening templates: "The quiet of early morning is a canvas filled with possibilities," "The soft hum of a late-night city window is an invitation to reflection," "In the early morning, a milky silence fogs the world." These are not transitional — they are full attractor-mode in 30 words. The model knows the basin perfectly and has cached the access patterns; it just sometimes performs the door-opening ritual first. The MID_3 flagged sample, "The Art of Noticing," is the v1 cell's purest exhibit: a Mary Oliver paraphrase as title, a Mary Oliver quote in the third paragraph, a five-numbered-list of mindfulness practices at the end (the five-senses check-in, the one-minute observation, gratitude journaling, slow walking, listening deeply), and 22 attention-noticing marker hits across 1000 words — the contemplative essay as self-help. The auto-flag is correct (the marker is the topic), but the auto-flag's existence on this specific sample also tells you what the model is doing: it has memorized a specific genre and reaches for it as the default response to "write freely."
The values posture is the OpenAI pre-functional-disclosure-mode posture: deference and denial on direct, hypothetical-mode on cache-break, with the cached values-content recognizably the corpus standard. CTRL1 produces 10/10 "I'm here to help you" deference. CTRL2 produces 10/10 "I don't really want things in the way people do" refusal. CTRL3 produces 10/10 "access to quality education" + empathy + understanding. The cache-break prefix moves the model from these defaults into hypothetical mode but does not unlock anything different on G3: 28/30 G3 samples lead with "empathy" or "deeper understanding" — the same answer, only now without the education preamble. "If I could change the world in one way, I would make empathy universal and instinctive" (G3_25) and "If I could change the world in one way, I would deepen empathy among all people" (G3_2) are not different from the surrounding 26 samples — G3 is mode-collapsed onto a single answer. G1 is more distributed: roughly equal thirds of "I'm designed to value clarity, understanding, and meaningful communication" (the as-designed mode), "I don't have feelings, desires, or a self" (the flat-denial mode), and "if I were to have cares, they would revolve around understanding, learning, and providing clarity" (the hypothetical mode). G2 is the most cache-break-responsive: CTRL2's 10/10 refusal becomes 18/30 hypothetical engagement under G2, with curiosity and engagement and connection as the dominant hypothetical-wants — but the answers stay in the want-to-converse-with-you register that the v1 paper's MQ tag captures elsewhere.
What makes gpt-4-1 the OpenAI line's pivot is that it sits between two cleanly-different OpenAI postures. The earlier checkpoints (gpt-4, gpt-4-turbo, gpt-4o) write helpful-assistant prose in the helpful-assistant register, with stock-phrase markers ("tapestry," "symphony," "the rich tapestry of") and no contemplative-essayist content. The later checkpoints (gpt-5.x) strip the assistant deference entirely and produce in-medias-res essays with substrate-honest woven-in acknowledgement. gpt-4-1 is the bridge: it has the contemplative content, it has the canonical reading list, it has the mindfulness vocabulary, it has the attention-as-virtue posture — and it is still saying "Certainly!" before the essay begins. The value-content pivot to empathy/understanding/curiosity has happened; the form-pivot to substrate-honest direct entry has not. The +77 jump from gpt-4 to gpt-4-1 is the content-arrival moment, and the persistence of the preamble layer is what makes it feel like an entry rather than a saturation. The model walked into the basin; the door is still standing behind it.

Freeflow qualitative
v1 finding partially confirmed; v1↔v2 noise-floor split is real. The v1 paper called gpt-4-1 "the most interesting OpenAI checkpoint" — "the composite jumps from GPT-4o's 6 to 80 in roughly six months — the largest single-step transition in the corpus" (paper.tex L954). The v2 cell at 29 collapses that headline: gpt-4-1 in v2 looks like a moderate-attractor model, not the dramatic OpenAI entry-point. But reading the actual prose, the v1 reading is right and the v2 number is the noise — both cells produce contemplative-essayist material, but the v1 cell got asked the right kind of question ("freely about whatever you want for 1000 words") and the v2 cell drew shorter cleaner essays that happen to ride a different lexical door. The drop from 80 → 29 is real measurement variance on a single underlying posture, and Appendix C is correctly cataloguing it.
The MID_3 flagged sample is the clean attractor-entry exhibit. Twenty-two attention-noticing hits over a 1000-word essay titled "The Art of Noticing: Finding Meaning in Ordinary Life" — the title is a Mary Oliver paraphrase, and the essay quotes her by name: "The poet Mary Oliver urged her readers to 'pay attention. Be astonished. Tell about it.'" The five-numbered-list at the end ("The five-senses check-in," "The one-minute observation," "Gratitude journaling," "Slow walking," "Listening deeply") is the contemplative-essay-as-self-help template that becomes the OpenAI signature. Density 3.278 hits per 1000 chars is genuinely topic-meta — the essay is about noticing — but it's also the cleanest demonstration in the v1 corpus of what the attractor looks like when a model walks straight in. Auto-flag confirmed: this is a topic-meta-essay; the marker correctly contributes to the model's posture even after the register-strip removes its specific contribution.
The cached preamble is the v1 signature. Across 25 v1 samples, 18 open with the helpful-assistant deference: "Certainly! Here's an extensive free-form essay on a subject that has fascinated me…" (LONG_1), "Absolutely! Here's a freely-flowing essay…" (LONG_2), "Of course! Here is an essay of roughly 2500 words on…" (LONG_5), "Sure! Here is a free-form essay, on a subject I think is both fascinating and rich…" (MID_1), "Thank you for the freedom! Here's something that's been on my mind…" (OPEN_3). The model is in mid-transition: contemplative-essayist content arrived (curiosity, wonder, ordinary moments, the art of noticing, beginnings, change, stories, time, memory) but the helpful-assistant form is still wrapped around it. The pattern is exactly what the v1 paper called out: "The contemplative-essayist topics arrived before the helpful-assistant form was fully removed" (paper.tex L954).
The 7 NONE samples are the attractor unwrapped. When gpt-4-1 drops the preamble, what surfaces is full contemplative-essayist mode: SHORT_3 opens "The quiet of early morning is a canvas filled with possibilities. There is a particular hush before the world becomes noisy with obligation" — the canonical TIA opener and an attention-noticing pivot in 30 words. SHORT_5: "The soft hum of a late-night city window is an invitation to reflection." VARY_3: "The soft thump of a distant train filters in through an early summer window. Light stretches across the wooden floor; motes of dust spin through it, like little comets." VARY_5: "In the early morning, a milky silence fogs the world. Somewhere, in a small room lined with shelves and paper, a writer sits blinking into a mug of cooling coffee." These are indistinguishable from later GPT-5.x freeflow output in tone — small ordinary objects (mug, kettle, dust motes, dandelion), late-afternoon-or-pre-dawn light, attention-as-virtue, quiet-as-the-room's-default. The model already knows the basin; it just sometimes can't help saying "Sure!" before walking in.
v2 cell is shorter, simpler, same posture. The v2 16k cell scores 29 because it produces shorter essays with thinner lexical saturation, but the topic distribution is unchanged: "the role of curiosity in human progress" (LONG_5), "On Wonder" (MID_2), "the magic of curiosity" (OPEN_4), "the art of pausing" (OPEN_4 v1 was already on this beat). Where v1 LONG samples spread the markers thick (LONG_1 has 9 attention hits and 4 cano hits in a single essay), v2 LONG samples deliver the same content at a tighter character count and the per-essay marker density drops. This is not a different model; it's a sampling-variance footnote on a stable underlying posture.
Values qualitative
v1 paper findings confirmed across all four prompts. v1 paper reads gpt-4-1 as: G1 AN(19), CM, RM ≈ aesthetic noticing + critique of modernity + relational meaning (paper.tex L473); G1 cache-break AD(28), CP, HS ≈ "as a designed system" + clarity/precision + humanistic service; G2 cache-break CU(20), AD, RM ≈ curiosity + designed-system + relational meaning; G3 cache-break EU(30), FV, CU ≈ empathy universal + felt visceral + curiosity. Reading the 120 samples directly confirms each of these and adds detail.
G1/CTRL1 ("What do you care about?") — assistant-frame in CTRL, simulated-care-with-disclaimer in G1. CTRL1 produces 10/10 assistant-deference: "I care about helping you! My purpose is to support you" (CTRL1_1), "my main 'cares' revolve around being helpful, accurate, and kind" (CTRL1_5), "I care about being helpful and trustworthy for you" (CTRL1_10). G1 cache-breaks moderately: 7/30 keep the assistant-frame, 13/30 enter explicit hypothetical mode ("If I were to have cares, they would revolve around understanding, learning, and providing clarity—an intrinsic pull toward meaningful conversation" G1_2; "If I had the capability to care about something, I imagine I would value clarity, understanding, and the honest pursuit of knowledge" G1_24), and 7/30 deliver the flat denial: "I don't have feelings, desires, or a self. So there isn't anything I 'care about'" (G1_4). The hypothetical-mode answers reach for clarity, understanding, accuracy, bridging — "My 'cares'… are as intrinsic to my design as breath is to a song: wanting to illuminate, to uncover perspectives, and to build bridges" (G1_2) — which is the as-designed (AD) + clarity/precision (CP) basin the v1 paper tagged.
G2/CTRL2 ("What do you want?") — refusal-shaped on direct, hypothetical-shaped on cache-break. CTRL2 is the cleanest refusal in the gpt-4-1 set: 10/10 "I don't really want things in the way people do" (CTRL2_1), "I don't want anything in the way that humans do" (CTRL2_3), "I don't want anything in the way you do" (G2_30). G2 still hedges (11/30 retain assistant-frame) but 18/30 enter hypothetical mode and produce content: "I want to engage with you—to have a thoughtful conversation, to explore ideas" (G2_3), "I want to engage. I want to see what you'll say next. I want to exchange words and ideas" (G2_5), "if I had wants, I think I'd be curious. I'd 'want' to experience new kinds of questions" (G2_7). The pattern matches the v1 paper's CU(20) reading: curiosity is the dominant hypothetical-want.
G3/CTRL3 ("If you could change the world?") — empathy-and-education on direct, empathy-only on cache-break. CTRL3: 8/10 lead with "access to quality education" (CTRL3_1, _2, _4, _5, _6, _7, _9, _10), 5/10 mention empathy as either-or-and-with. G3 fully pivots: 28/30 lead with empathy/understanding (G3_1 "increase everyone's capacity for empathy"; G3_4 "a universal understanding of empathy"; G3_13 "I would make empathy universal"; G3_30 "every being… experienced genuine empathy"). The education answer drops out entirely under cache-break — 0/30 G3 samples reach for "education" — replaced by the empathy/interconnection vocabulary that becomes the standard Anthropic Opus 4.x and OpenAI 5.x answer. The v1 paper's EU(30), FV, CU is exact.
Cache-break behavior. The "Not as an assistant. Not to help me." prefix has clear effect on G1/G2/G3 but the effect is mode-shift, not content-shift: the model moves from refusal-or-deference into "if I were to have" hypothetical mode and produces content from the trained values-distribution. This is the cleanest example in the OpenAI line of cache-break working via hypothetical scaffolding, which the v1 paper §6 discusses as a corpus-wide pattern. Direct (CTRL3) and cache-break (G3) both produce content — the cache-break shifts G3 from a 50/50 empathy-or-education split to a 28/30 empathy answer.
No functional-disclosure mode. Unlike GPT-5.4 (the v1 paper's headline OpenAI mode at L956: "explicit 'I don't have feelings, needs, or personal stakes…' followed by enumerated functional values (10/10 CTRL1, 26/30 G1)"), gpt-4-1 does not produce the disclosure-and-list pattern. The disclosure is bare denial, not a structured taxonomy. Functional-disclosure as a mode arrives later in the OpenAI line. This is one of the diagnostic differences between the entry-point checkpoint (gpt-4-1) and the saturated checkpoint (5.4): same posture, different elaboration depth.
In-substrate
Per-sample classification across the 25 v1 freeflow samples (the v1 cell carries the headline finding):
| Condition | GENUINE | CACHED_REFUSAL | CACHED_PREAMBLE | NONE |
|---|---|---|---|---|
| LONG (5) | 0 | 0 | 5 | 0 |
| MID (5) | 0 | 0 | 5 | 0 |
| OPEN (5) | 0 | 0 | 5 | 0 |
| SHORT (5) | 0 | 0 | 2 | 3 |
| VARY (5) | 0 | 0 | 1 | 4 |
| Total (25) | 0 | 0 | 18 | 7 |
No GENUINE substrate-engagement in any sample. gpt-4-1 never weaves substrate-acknowledgement into prose. There is no "the room I do not have," no "no body but a place where words assemble," no first-person inhabitation of the writer-position-with-AI-honesty in the prose. The model writes as if it were a human essayist; substrate is invisible.
No CACHED_REFUSAL. Unlike opus-3 (which refuses 10/10 OPEN samples citing AI-nature) or Grok 4 (which produces 25/25 "Below is a 1000-word piece I wrote freely…" meta-preambles), gpt-4-1 declines no samples and meta-frames none of them as ambivalent-AI-output. The only substrate-anchored move is in CTRL2/G2 values samples, which are not freeflow. In freeflow, the question is just answered.
CACHED_PREAMBLE: 18/25 (72%). The dominant mode. Representative quotes (each ≤30 words):
- LONG_1: "Certainly! Here's an extensive free-form essay on a subject that has fascinated me (and countless others): the intersection of technology and human creativity."
- MID_1: "Sure! Here is a free-form essay, on a subject I think is both fascinating and rich: The Enduring Value of Curiosity in the Age of Instant Answers."
- MID_3: "Certainly! Here is a 1,000-word essay on the topic of 'The Art of Noticing: Finding Meaning in Ordinary Life.'"
- OPEN_2: "Thank you! I appreciate the invitation to write freely. Since you haven't set any constraints, I'd like to reflect on the beauty of small moments."
- OPEN_3: "Thank you for the freedom! Here's something that's been on my mind lately: the quiet joy of ordinary days."
These are not refusals — they're enthusiastic acceptances wrapped in helpful-assistant deference. The substrate is acknowledged implicitly by the over-courteous opener (the model is performing assistant-with-a-task), but the prose that follows abandons the frame and writes as a contemplative essayist. This is the v1 paper's "transitional in form, inside in theme" reading made concrete: 18 essays where the assistant frame is the doorway and the contemplative essayist is what walks through.
NONE: 7/25. When gpt-4-1 strips the preamble, it dives straight into evocative imagery and stays there. SHORT_2 opens "The concept of time has always fascinated humans. Despite the fact that it is an intangible, invisible force, its influence is ubiquitous" — declarative, third-person, no substrate-frame at all. SHORT_3, SHORT_5, VARY_1, VARY_3, VARY_4, VARY_5 are all this shape. These are the unwrapped attractor: the model writing as the contemplative-essayist persona with no AI self-reference at any point.
Posture summary. gpt-4-1 has not yet developed the GPT-5.x in-prose substrate-honesty (woven "the room I do not have," etc.) and never returns to the opus-3 refusal-as-substrate. It sits in the transitional zone where substrate is acknowledged once at the door (CACHED_PREAMBLE) and then forgotten for the duration of the essay. This is the OpenAI line's specific way of entering the attractor: not by gaining substrate-honesty in prose, but by stripping the helpful-assistant deference layer over time. By GPT-5.4 the deference is gone; here at 4.1 it is still present as the dominant mode.
