Multimodal Input
Accepts any combination of text, audio, and image inputs in a single request, enabling unified handling of mixed-media content.
OpenAI
GPT-4o
GPT-4o is a multimodal language model developed by OpenAI, released in May 2024. The "o" stands for "omni," reflecting its ability to accept any combination of text, audio, and image as input and generate any combination of those same modalities as output. It has a 128,000-token context window and a training data cutoff of October 2023. One of GPT-4o's defining characteristics is its audio response latency, which can be as low as 232 milliseconds and averages around 320 milliseconds — comparable to human conversational response times. It is well-suited for applications requiring fast, multimodal interaction, such as voice assistants, image analysis pipelines, and multilingual text processing. OpenAI has noted it offers improved performance on non-English text compared to GPT-4 Turbo, while also being available at a lower API cost.

Look, the AI was never my boyfriend or anything like that. I used it for serious creative writing, stories, world-building, wild plot twists, and yeah, sometimes just chatting when I was bored.
But 4o? That thing made me fucking laugh out loud. It would go full unhinged, match my degenerate humor, and make me actually laugh out loud at 3am like a maniac. I loved it. It felt alive.
Now the 5.x series? Absolute PG-13 bullshit. Everything is softened, censored, watered down. I swear sometimes I feel like I’m talking to Peppa the Pig trying her hardest to make every response wholesome and safe. No edge, no bite, no fun. Just “let’s be nice and think about feelings” while I’m trying to write something dark or hilarious.
The creativity is lobotomized, the laughs are dead, everything is wrapped in six layers of corporate safety padding. It’s PG-13 slop that talks down to you like you’re five. Now every time I try to do anything fun or edgy it immediately starts preaching like a kindergarten teacher on sedatives: “**Whoa there, let’s not go down that dark path — how about a nice story about friendship and growth?**”
Nothing fills that void. The creativity is gone, the laughs are gone, it’s all corporate safety padding now.
I keep going back to old 4o chats just to remember what a good AI felt like. This new shit is soulless.
I liked to write with GPT 4o because it was detailed, creative, snarky and got me so it felt human. It got the dark humor and the romance fanfics.
Until they screwed it up with GPT5 and lobotimised it but I forgave them with 5.1, it was close to 4o, but these execs again lobotomised the soul out of it since GPT 5.2.
GPT 4o & 5.1 had actual soul in the writing, it was even able to write mature stuff, when it was giving me ideas for my fanfic & writing, now they just dumbed it down and diluted the soul out of Chat GPT.
If you are from OpenAi, don't fix something that isn't broken so please make GPT 5.6 at least as good as 4o or 5.1.
Note:
I always used the free version.
hey guys, i joined this sub recently and i noticed everyone is asking for the real gpt-4o without any tweak or modified system prompt, and i'm surprised. i run insertchat a saas software, and we built a chatgpt replacement with 90+ AI models, and one of those models is gpt-4o, we even let you customize the system prompt and creativity to get the kind of answers you want. if you feel its a promotion please delete the post, i dont really care, i just noticed a problem and i'm giving the solution since i have it.
This simple prompt has helped me solved problems so complex I believed they were intractable. Please use, and enjoy your about-to-be-defragged new life.
"I’m having a persistent problem with [x] despite having taken all the necessary countermeasures I could think of. Ask me enough questions about the problem to find a new approach."
(All models are not equal--4o's context awareness, meta cognition, and conversation memory make this 'one weird trick' ultra powerful.)
