GPT-4o ("o" for "omni") and GPT-4o mini are natively multimodal models designed to handle a combination of text, audio, and video inputs, and can generate outputs in text, audio, and image formats. GPT-4o mini is the lightweight version of GPT-4o.
Before GPT-4o, users could interact with ChatGPT using Voice Mode, which operated with three separate models. GPT-4o integrates these capabilities into a single model that's trained across text, vision, and audio. This unified approach ensures that all inputs — whether text, visual, or auditory — are processed cohesively by the same neural network.
GPT-4o mini is the next iteration of this omni model family, available in a smaller and cheaper version. This model offers higher accuracy than GPT-3.5 Turbo while being just as fast and supporting multimodal inputs and outputs.
Currently, the gpt-4o-mini model supports {text, image}, with {text} outputs, the same modalities as gpt-4-turbo. As a preview, we will also be using the gpt-4o-audio-preview model to showcase transcription though the GPT4o model.
Once we have this setup, let's start with a simple {text} input to the model for our first request. We'll use both system and user messages for our first request, and we'll receive a response from the assistant role.
from openai import OpenAI import os## Set the API key and model nameMODEL="gpt-4o-mini"client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY", "<your OpenAI API key if not set as an env var>"))
completion = client.chat.completions.create(model=MODEL,messages=[ {"role": "system", "content": "You are a helpful assistant. Help me with my math homework!"}, # <-- This is the system message that provides context to the model {"role": "user", "content": "Hello! Could you solve 2+2?"} # <-- This is the user message for which the model will generate a response ])print("Assistant: "+ completion.choices[0].message.content)
# Open the image file and encode it as a base64 stringdefencode_image(image_path):withopen(image_path, "rb") as image_file:return base64.b64encode(image_file.read()).decode("utf-8")base64_image = encode_image(IMAGE_PATH)response = client.chat.completions.create(model=MODEL,messages=[ {"role": "system", "content": "You are a helpful assistant that responds in Markdown. Help me with my math homework!"}, {"role": "user", "content": [ {"type": "text", "text": "What's the area of the triangle?"}, {"type": "image_url", "image_url": {"url": f"data:image/png;base64,{base64_image}"} } ]} ],temperature=0.0,)print(response.choices[0].message.content)
To find the area of the triangle, you can use the formula:
\[
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
\]
In the triangle you provided:
- The base is \(9\) (the length at the bottom).
- The height is \(5\) (the vertical line from the top vertex to the base).
Now, plug in the values:
\[
\text{Area} = \frac{1}{2} \times 9 \times 5
\]
Calculating this:
\[
\text{Area} = \frac{1}{2} \times 45 = 22.5
\]
Thus, the area of the triangle is **22.5 square units**.

While it's not possible to directly send a video to the API, GPT-4o can understand videos if you sample frames and then provide them as images.
Since GPT-4o mini in the API does not yet support audio-in (as of July 2024), we'll use a combination of GPT-4o mini and Whisper to process both the audio and visual for a provided video, and showcase two usecases:
We'll use two python packages for video processing - opencv-python and moviepy.
These require ffmpeg, so make sure to install this beforehand. Depending on your OS, you may need to run brew install ffmpeg or sudo apt install ffmpeg
import cv2from moviepy import*import timeimport base64# We'll be using the OpenAI DevDay Keynote Recap video. You can review the video here: https://www.youtube.com/watch?v=h02ti0Bl6zkVIDEO_PATH="data/keynote_recap.mp4"
defprocess_video(video_path, seconds_per_frame=2): base64Frames = [] base_video_path, _ = os.path.splitext(video_path) video = cv2.VideoCapture(video_path) total_frames =int(video.get(cv2.CAP_PROP_FRAME_COUNT)) fps = video.get(cv2.CAP_PROP_FPS) frames_to_skip =int(fps * seconds_per_frame) curr_frame=0# Loop through the video and extract frames at specified sampling ratewhile curr_frame < total_frames -1: video.set(cv2.CAP_PROP_POS_FRAMES, curr_frame) success, frame = video.read()ifnot success:break _, buffer = cv2.imencode(".jpg", frame) base64Frames.append(base64.b64encode(buffer).decode("utf-8")) curr_frame += frames_to_skip video.release()# Extract audio from video audio_path =f"{base_video_path}.mp3" clip = VideoFileClip(video_path) clip.audio.write_audiofile(audio_path, bitrate="32k") clip.audio.close() clip.close()print(f"Extracted {len(base64Frames)} frames")print(f"Extracted audio to {audio_path}")return base64Frames, audio_path# Extract 1 frame per second. You can adjust the `seconds_per_frame` parameter to change the sampling ratebase64Frames, audio_path = process_video(VIDEO_PATH, seconds_per_frame=1)
MoviePy - Writing audio in data/keynote_recap.mp3
MoviePy - Done.
Extracted 218 frames
Extracted audio to data/keynote_recap.mp3
## Display the frames and audio for contextdisplay_handle = display(None, display_id=True)for img in base64Frames: display_handle.update(Image(data=base64.b64decode(img.encode("utf-8")), width=600)) time.sleep(0.025)Audio(audio_path)
Now that we have both the video frames and the audio, let's run a few different tests to generate a video summary to compare the results of using the models with different modalities. We should expect to see that the summary generated with context from both visual and audio inputs will be the most accurate, as the model is able to use the entire context from the video.
The visual summary is generated by sending the model only the frames from the video. With just the frames, the model is likely to capture the visual aspects, but will miss any details discussed by the speaker.

The results are as expected - the model is able to capture the high level aspects of the video visuals, but misses the details provided in the speech.
The audio summary is generated by sending the model the audio transcript. With just the audio, the model is likely to bias towards the audio content, and will miss the context provided by the presentations and visuals.
{audio} input for GPT-4o is currently in preview, but will be incorporated into the base model in the near future. Because of this, we will use the gpt-4o-audio-preview model to process the audio.

The audio summary is biased towards the content discussed during the speech, but comes out with much less structure than the video summary.
The Audio + Visual summary is generated by sending the model both the visual and the audio from the video at once. When sending both of these, the model is expected to better summarize since it can perceive the entire video at once.

After combining both the video and audio, we're able to get a much more detailed and comprehensive summary for the event which uses information from both the visual and audio elements from the video.
For the Q&A, we'll use the same concept as before to ask questions of our processed video while running the same 3 tests to demonstrate the benefit of combining input modalities:
Visual Q&A
Audio Q&A
Visual + Audio Q&A
QUESTION="Question: Why did Sam Altman have an example about raising windows and turning the radio on?"
qa_visual_response = client.chat.completions.create(model=MODEL,messages=[ {"role": "system", "content": "Use the video to answer the provided question. Respond in Markdown."}, {"role": "user", "content": ["These are the frames from the video.",*map(lambda x: {"type": "image_url", "image_url": {"url": f'data:image/jpg;base64,{x}', "detail": "low"}}, base64Frames),QUESTION ], } ],temperature=0,)print("Visual QA:\n"+ qa_visual_response.choices[0].message.content)
Visual QA:
Sam Altman used the example of raising windows and turning the radio on to illustrate the concept of function calling in AI. This example demonstrates how AI can interpret natural language commands and translate them into specific function calls, making interactions more intuitive and user-friendly. By showing a relatable scenario, he highlighted the advancements in AI's ability to understand and execute complex tasks based on simple instructions.
qa_audio_response = client.chat.completions.create(model=MODEL,messages=[ {"role": "system", "content":"""Use the transcription to answer the provided question. Respond in Markdown."""}, {"role": "user", "content": f"The audio transcription is: {transcription}. \n\n{QUESTION}"}, ],temperature=0,)print("Audio QA:\n"+ qa_audio_response.choices[0].message.content)
Audio QA:
The transcription provided does not include any mention of Sam Altman discussing raising windows or turning the radio on. Therefore, I cannot provide an answer to that specific question based on the given text. If you have more context or another transcription that includes that example, please share it, and I would be happy to help!
qa_both_response = client.chat.completions.create(model=MODEL,messages=[ {"role": "system", "content":"""Use the video and transcription to answer the provided question."""}, {"role": "user", "content": ["These are the frames from the video.",*map(lambda x: {"type": "image_url", "image_url": {"url": f'data:image/jpg;base64,{x}', "detail": "low"}}, base64Frames), {"type": "text", "text": f"The audio transcription is: {transcription}"},QUESTION ], } ],temperature=0,)print("Both QA:\n"+ qa_both_response.choices[0].message.content)
Both QA:
Sam Altman used the example of raising windows and turning the radio on to illustrate the new function calling feature in GPT-4 Turbo. This example demonstrates how the model can interpret natural language commands and translate them into specific function calls, making it easier for users to interact with the model in a more intuitive way. It highlights the model's ability to understand context and perform multiple actions based on user instructions.
Comparing the three answers, the most accurate answer is generated by using both the audio and visual from the video. Sam Altman did not discuss the raising windows or radio on during the Keynote, but referenced an improved capability for the model to execute multiple functions in a single request while the examples were shown behind him.
Integrating many input modalities such as audio, visual, and textual, significantly enhances the performance of the model on a diverse range of tasks. This multimodal approach allows for more comprehensive understanding and interaction, mirroring more closely how humans perceive and process information.
Currently, GPT-4o and GPT-4o mini in the API support text and image inputs, with audio capabilities coming soon. For the time being, use the gpt-4o-audio-preview for audio inputs.
