Kimi API Nvidia — Access Kimi K2.5 for Free
Quick Answer
The **Kimi API** is accessible for free through Nvidia's NIM inference catalog.
Nvidia hosts the **nvidia kimi 2.5 api** on its high-speed infrastructure, granting developers access to the flagship model with free starter credits.
By generating a key on the Nvidia developer portal, you can utilize the **nvidia kimi 2.5 api free** tier and make compatible calls using the base URL https://integrate.api.nvidia.com/v1.
What is Kimi API Nvidia
The nvidia kimi api is a deployment partnership between Moonshot AI and Nvidia. It brings the Kimi K2.5 language models to Nvidia's NIM (Nvidia Inference Microservice) catalog. This enables developers to build and test projects using the **nvidia kimi k2.5 api** without needing credit cards or upfront billing setup on Moonshot's direct console.
By deploying the **kimi k2 5 api nvidia** model group across Nvidia's optimized GPU data centers, this service delivers exceptional throughput and low token latency.
How Nvidia Kimi API Works
When you query the **nvidia kimi api**, requests are sent to Nvidia's central routing engine instead of Moonshot's Chinese servers. The response formatting remains fully OpenAI-compatible. This means you only need to update the authorization header and base URL in your existing scripts to start testing for free.
How to Access Nvidia Kimi API Free
To integrate the **nvidia kimi 2.5 api free** version, perform the following steps:
- Visit the Nvidia API Catalog at
build.nvidia.com. - Locate the Kimi K2.5 model listing page.

import openai
client = openai.OpenAI(
api_key="your_nvidia_nim_api_key_here",
base_url="https://integrate.api.nvidia.com/v1"
)
response = client.chat.completions.create(
model="deepmind/kimi-k2-5", # Model namespace on Nvidia NIM
messages=[
{"role": "user", "content": "Write a fast script to sort a list in Python."}
],
