DeepInfra raises $107M Series B to scale the inference cloud — read the announcement

Imagine going to an art gallery where paintings tell their stories. That’s what "Talking Images" do in practice. This tutorial shows you how to make art speak using DeepInfra models. We are going to use:
1-) deepseek-ai/Janus-Pro-7B
2-) hexgrad/Kokoro-82M
First, let’s set up your environment. You’ll need these packages. Here’s the content of requirements.txt:
gradio
requests
python-dotenv
pillow
scipy
numpy
python -m venv venv && (venv\Scripts\activate.bat 2>nul || source venv/bin/activate) && pip install -r requirements.txt
Next, create a .env file in your project folder. Copy your DEEPINFRA_API_TOKEN into it. Your .env file should look like this:
DEEPINFRA_API_TOKEN=your-api-token-here
Replace your-api-token-here with your actual DeepInfra API token.
Here’s the Python code that makes your images talk. It uses Janus-Pro-7B to describe the image and Kokoro-82M to turn that description into audio.
import os
from io import BytesIO
import gradio as gr
import base64
import requests
from dotenv import load_dotenv, find_dotenv
from scipy.io import wavfile
import numpy as np
_ = load_dotenv(find_dotenv())
def analyze_image(image) -> str:
url = "https://api.deepinfra.com/v1/inference/deepseek-ai/Janus-Pro-7B"
headers = {"Authorization": f"bearer {api_token}"}
buffered = BytesIO()
if image.mode == "RGBA":
image = image.convert("RGB")
format = "JPEG" if image.format == "JPEG" else "PNG"
image.save(buffered, format=format)
files = {"image": ("my_image." + format.lower(), buffered.getvalue(), f"image/{format.lower()}")}
data = {
"question": "I am this image. You must describe me in my own voice using 'I'. State my colors, shapes, mood, and any notable features with precise detail. Examples: 'I have clouds,' 'I contain sharp lines.' Be vivid, thorough, and factual."
}
response = requests.post(url, headers=headers, files=files, data=data)
return response.json()["response"]
def text_to_speech(text: str) -> tuple:
url = "https://api.deepinfra.com/v1/inference/hexgrad/Kokoro-82M"
headers = {
"Authorization": f"bearer {api_token}",
"Content-Type": "application/json"
}
data = {
"text": text
}
response = requests.post(url, json=data, headers=headers)
res_json = response.json()
audio_base64 = res_json["audio"].split(",")[1]
audio_bytes = base64.b64decode(audio_base64)
audio_io = BytesIO(audio_bytes)
sample_rate, audio_data = wavfile.read(audio_io)
return sample_rate, audio_data
def make_image_talk(image):
description = analyze_image(image)
sample_rate, audio_data = text_to_speech(description)
return sample_rate, audio_data
if __name__ == "__main__":
api_token = os.environ.get("DEEPINFRA_API_TOKEN")
interface = gr.Interface(
fn=make_image_talk,
inputs=gr.Image(type="pil"),
outputs=gr.Audio(type="numpy"),
title="Art That Talks Back",
description="Upload an image and hear it talk!"
)
interface.launch()

Nemotron 3 Nano vs GPT-OSS-20B: Performance, Benchmarks & DeepInfra Results<p>The open-source LLM landscape is becoming increasingly diverse, with models optimized for reasoning, throughput, cost-efficiency, and real-world agentic applications. Two models that stand out in this new generation are NVIDIA’s Nemotron 3 Nano and OpenAI’s GPT-OSS-20B, both of which offer strong performance while remaining openly available and deployable across cloud and edge systems. Although both […]</p>
Best API Providers for NVIDIA Nemotron 3 Super 120B<p>Nemotron 3 Super 120B is available across a growing number of hosted APIs and deployment platforms. At 120B total parameters with 12B active per inference pass, the right provider matters: latency, throughput, and cost vary significantly depending on where you run it. This guide covers the top options by use case — from fully managed […]</p>
Best API Providers for GLM-5.1 in 2026<p>GLM-5.1 is available across a growing number of API providers, and the choice between them materially affects cost, latency, and what features you can actually use. The benchmark spread is real: blended pricing runs from $0.74 to $1.70 per 1M tokens across tracked providers, output speed ranges from 33 to 175 t/s, and not every […]</p>
