GPT-4o (“o” for “omni”) is a step towards much more natural human-computer interaction—it accepts as input any combination of text, audio, and image and generates any combination of text, audio, and image outputs. It can respond to audio inputs in as little as 232 milliseconds, with an average of 320 milliseconds, which is similar to human response time(opens in a new window) in a conversation. It matches GPT-4 Turbo performance on text in English and code, with significant improvement on text in non-English languages, while also being much faster and 50% cheaper in the API. GPT-4o is especially better at vision and audio understanding compared to existing models.

Prior to GPT-4o, you could use Voice Mode to talk to ChatGPT with latencies of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4) on average. To achieve this, Voice Mode is a pipeline of three separate models: one simple model transcribes audio to text, GPT-3.5 or GPT-4 takes in text and outputs text, and a third simple model converts that text back to audio. This process means that the main source of intelligence, GPT-4, loses a lot of information—it can’t directly observe tone, multiple speakers, or background noises, and it can’t output laughter, singing, or express emotion.

GPT-4o’s text and image capabilities are starting to roll out today in ChatGPT. We are making GPT-4o available in the free tier, and to Plus users with up to 5x higher message limits. We’ll roll out a new version of Voice Mode with GPT-4o in alpha within ChatGPT Plus in the coming weeks.

        I never had any luck with most of the extensions let alone figuring out how to format a prompt for the API. I’m just making shit up as I go.

      If you already didn’t know, you can run locally some small models with an entry level GPU.

      For example i can run Llama 3 8B or Mistral 7B on a 1060 3GB with Ollama. It is about as bad as GPT-3 turbo, so overall mildly useful.

      Although there is quite a bit of controversy of what is an “open source” model, most are only “open weight”

        Emphasis on “small” models. The large ones need over a terabyte of RAM and it has to be high bandwidth (DDR is not fast enough).

        And for most tasks, smaller models hallucinate way too often. Even the largest models are only just barely good enough.

          Llama 2 70B can run on a specc-ed out current gen MacBook Pro. Not cheap hardware in any sense, but it isn’t a large data center cluster.

        I been playing with the Mistral 7b models. About the most my hardware can reasonably run… so far. Would love to add vision and voice but I’m just happy it can run.

          I’ve been wanting to run that one on my hardware but GPT4All just refuses to start its GUI. The only thing is a “chat.exe” that sits idle in the task manager. And this is an issue I’ve seen reported in their Github from several users, on both Win 10 and 11.

          Have you find success with that frontend, or are you using one that actually works? I haven’t researched any others since this issue has me a little burnt out.

      I have this running at home on a used r630 (CPU only). oobabooga/automatic1111 for LLM/SD backends, vosk + mimic3 for tts/stt. A little bit of custom python to tie it all together. I certainly don’t have latency as low as theirs, but it’s definitely conversational when my sentences are short enough.
