404s, click-bots, and sticker shock
GPT-5.4 Thinking System Card
It clicks through Gmail; crowd splits over sky-high prices, 1M memory, and a military vibe
TLDR: OpenAI’s GPT‑5.4 adds cyber safety features and can click through Gmail like a human while boasting a huge 1M “memory.” The crowd is split: some love the power, others slam the clicky interface, balk at pricing, and worry about military use—plus a 404 turned into a meme.
OpenAI dropped its shiny new “GPT‑5.4 Thinking” and the vibes are chaotic. The first general model with added cyber‑safety got people peeking at its system card—only for one commenter to hit a 404 and turn it into a meme. Then came the flex: a gigantic 1 million‑token “memory” (think: it can read and remember a huge amount of text), which fans like minimaxir say doesn’t cost extra past 200k on the pricing page. But the real brawl is about how the bot clicks around Gmail like a human using screenshots and coordinates. One camp cheers the “robot intern” energy; the other screams, “Use the Gmail API, not whack‑a‑mole clicks!”
Money talk lit the comments on fire. denysvitali’s “Wtf” landed after seeing $2.50 per million tokens to input and $15 to output for gpt‑5.4, while the pro tier jumps to $30 in and $180 out—tokens are the tiny pieces of text AI uses. Security vibes? Chance‑Device dropped the cold take: “I’m sure the military will enjoy it,” which sent a chill. So yes, bigger brain, safer cyber, and a bot that literally clicks send—but the crowd is split between awe, anxiety, and sticker shock.
Key Points
- •GPT‑5.4 Thinking is introduced as the latest reasoning model in the GPT‑5 series.
- •It adopts comprehensive safety mitigations similar to prior GPT‑5 models.
- •It is the first general‑purpose model to implement mitigations for high‑capability cybersecurity.
- •Its cyber safety builds on approaches from GPT‑5.3 Codex used in ChatGPT and the API.
- •The model is also referred to as gpt-5.4-thinking; baseline comparisons use GPT‑5.2 Thinking since no GPT‑5.3 Thinking exists.
