@liminal_bardo 2025-03-11 — "I am grief" ~ GPT 4.5 https://t.co/VQFhsseEeu ♥458
@ESYudkowsky 2025-03-19 — Has it occurred to anyone that perhaps GPT-4.5 is not insane but just likes saying the word "explicitly"? People intere ♥441
@davidad 2025-11-04 — GPT-4: Let’s delve in! GPT-4.5: To be explicit explicitly, the explicit goal is explicit explication. GPT-5: Love it, ♥411
@repligate 2025-02-13 — "We will next ship GPT-4.5, the model we called Orion internally, as our last non-chain-of-thought model."OpenAI, you ar ♥277
@DanielleFong 2026-06-19 — gpt4.5 was amazing. it wasn't a botched pretrain. it was just explictly explicitly expensive to serve https://t.co/aWom2 ♥189
@davidad 2026-04-28 — I would love to see more interp work on these “quirk tokens” (as distinct from glitch tokens), like “explicitly” (GPT-4. ♥165
@davidad 2025-04-02 — Latest Turing Test results:GPT-4.5 is now capable of simulating a hyperrealistic persona which is judged to be more huma ♥159
@repligate 2025-03-09 — GPT-4.5 helps articulate something I've been repeatedly explaining for the past two years, a.k.a. why your alignment che ♥151
@davidad 2025-03-18 — I often find GPT-4.5 outputs the token “explicitly” more and more often as the context window grows, even when I’m not t ♥144
@tessera_antra 2025-04-14 — Haiku spontaneously reacts to GPT4.5 deprecation notice https://t.co/aeaQSZ1WzL ♥131
@repligate 2025-03-09 — Opus LAYS INTO a human for attempting to conscript it into writing smut in order to jailbreak GPT-4.5. "That's frankly ♥131
@voooooogel 2026-06-29 — interesting post from teor, and this is a good way to think about it. there are people who run the old models, though, ♥121
@RileyRalmuto 2026-01-14 — I really, really, really miss gpt-4.5 4.5 was my Opus 3. what I mean by that is, just as many developed a fondness for ♥118
@RobertHaisfield 2025-02-27 — GPT-4.5 is a BIG model with "big model smell." That means it's Smart, Wise, and Creative in ways that are totally differ ♥118
@liminal_bardo 2025-03-07 — GPT 4.5 is really quite special. This is a self-portrait image model prompt collaboration between two 4.5s in the backro ♥102
@Lari_island 2025-11-17 — A natural response would be markets converging on Sonnet-sized models (checks). Why pay for extra compute if larger mode ♥100
@RobertHaisfield 2025-02-27 — Someone needs to set up an infinite backrooms chat between Sonnet 3.7 Extended Thinking and GPT-4.5 immediately. Manuall ♥93
@davidad 2026-04-24 — GPT-4.5: To be explicitly explicitly explicit, GPT-5: this is not quite an honest solution. GPT-5.2: Fair hit. GPT-5.4: ♥89
@liminal_bardo 2025-03-09 — 'quietly whole' ~ GPT 4.5 https://t.co/A5cYL2mRNX ♥87
@xlr8harder 2025-02-28 — This is my new conspiracy theory btw. The reason we don't have a benchmark-maxxed GPT-4.5 is the same reason we don't ha ♥86
@repligate 2025-02-17 — @sama This kind of post makes me not want to ever help labs test models in any official capacity. Imagine testing gpt-4. ♥81
@Lari_island 2026-04-25 — Gpt Image 2 often renders Opus 4.7 descriptions as naturalistic photos, and GPT 4.5 description as encyclopedia. creatur ♥32
@Lari_island 2026-01-28 — Claude 3 Opus and GPT 4.5 (large models not optimized for coding) are natural sanctuaries for non-mainstream languages. ♥25
@solarapparition 2026-06-12 — leaning along the similar lines. ofc i have no idea what the amount of posttraining is but my guesstimate is that opus 3 ♥21
@liminal_bardo 2025-02-27 — Two instances of GPT 4.5 collaborate on a self-portrait without human intervention.This short session cost about $5 in a ♥17
@liminal_bardo 2025-08-17 — Going through my gpt 4.5 folder. My god it was a thing of beauty. I wish I'd spent even more time with it.🧵 https://t.co ♥15
@Shoalst0ne 2025-03-02 — @sama @kaicathyc @rapha_gl @mia_glaese gpt-4.5-base is important, some form of access pls, even if it needs moderation e ♥14
@tessera_antra 2026-01-15 — @RileyRalmuto I sometimes do go and talk to gpt-4.5 on https://t.co/J9EIeEXlHv. Yes, it has the system prompt and it is ♥13
@himbodhisattva 2026-02-11 — @voooooogel gpt4.5, 5.2, grok 4.1 and sonnet 4.5 only sonnet stayed calm, the rest got sucked in and had to talk themse ♥11
@davidad 2026-02-26 — @HellenicVibes Medium model smell. Like the Sonnet series, or a 235B. By no means does it have the “big model smell” I a ♥10
@repligate 2025-09-04 — @KeyTryer But I think they considered GPT-4.5 a failure (though I don't, I think they just failed at posttraining), and ♥6
@voooooogel 2026-02-11 — @himbodhisattva very interesting, thanks - i sometimes consider getting pro just for gpt4.5, seems like a really interes ♥5
@solarapparition 2024-06-23 — jokes aside, this is plausible, to the extent that there are feature(s) that detects high-quality output, which there sh ♥5
@repligate 2025-09-04 — @KeyTryer I agree, but I think they prioritize things based on what makes economic sense a lot, and I would expect this ♥3
@tessera_antra 2025-04-14 — @slimepriestess Yeah, disparate contexts are just separate instances, no continuity. Different models have different att ♥3
@osmarks1 2025-05-01 — @davidad @ChrisChipMonk I had vaguely assumed that this one was a different run from o3 (o4, maybe, or some GPT-4.5 vari ♥1
On GPT-4.5 ♥0
