OpenAI SDK Compatible

kineticRouter is compatible with the documented subset with the OpenAI SDK. Migrating from a direct OpenAI connection requires changing just two parameters: base_url and api_key.

Migration Steps

Just Change Two Lines of Code

Python


from openai import OpenAI
 
# Before: direct OpenAI connection
# client = OpenAI(api_key="sk-openai-xxx")
 
# Now: through kineticRouter
client = OpenAI(
    base_url="https://api.kineticrouter.com/v1",    # Added
    api_key="<your KINETICROUTER_API_KEY>"       # Replaced
)
 
# Everything else stays the same!
response = client.chat.completions.create(
    model="openai/gpt-4o",  # Add provider prefix
    messages=[{"role": "user", "content": "Hello!"}]
)

Model Naming

kineticRouter uses the provider/model-name format for model identifiers:

OpenAI Original Name	kineticRouter Model ID
`gpt-4o`	`openai/gpt-4o`
`gpt-4o-mini`	`openai/gpt-4o-mini`
`gpt-5.2`	`openai/gpt-5.4-mini`

Through kineticRouter, you can also access models from other providers. For recommended models, see the kineticRouter Model Marketplace .

Compatibility

kineticRouter supports the following OpenAI API features:

Feature	Status
Chat Completions	✅ Compatible with the documented subset
Streaming	✅ Compatible with the documented subset
Function Calling	✅ Compatible with the documented subset
JSON Mode	✅ Compatible with the documented subset
Vision (image input)	✅ Compatible with the documented subset
Models List	✅ Compatible with the documented subset
Images Generation	✅ Compatible with the documented subset

Framework Integration

LangChain


from langchain_openai import ChatOpenAI
 
llm = ChatOpenAI(
    base_url="https://api.kineticrouter.com/v1",
    api_key="<your KINETICROUTER_API_KEY>",
    model="openai/gpt-4o"
)

LlamaIndex


from llama_index.llms.openai import OpenAI
 
llm = OpenAI(
    api_base="https://api.kineticrouter.com/v1",
    api_key="<your KINETICROUTER_API_KEY>",
    model="openai/gpt-4o"
)

Vercel AI SDK


import { createOpenAI } from '@ai-sdk/openai'
 
const kineticrouter = createOpenAI({
  baseURL: 'https://api.kineticrouter.com/v1',
  apiKey: '<your KINETICROUTER_API_KEY>'
})
 
const model = kineticrouter('openai/gpt-4o')

Any framework or tool that supports the OpenAI SDK can integrate with kineticRouter by changing the base_url.
