langchain-telnyx

An integration package connecting Telnyx AI Inference and LangChain.

Telnyx provides OpenAI-compatible LLMs hosted on its own GPU infrastructure. See the Available Models page for the full list.

Installation

pip install langchain-telnyx

Chat Models

from langchain_telnyx import ChatTelnyx

chat = ChatTelnyx(model="moonshotai/Kimi-K2.6")
response = chat.invoke("Hello!")

Embeddings

from langchain_telnyx import TelnyxEmbeddings

embeddings = TelnyxEmbeddings(model="thenlper/gte-large")
vectors = embeddings.embed_query("Hello world")

Configuration

Set the TELNYX_API_KEY environment variable with your Telnyx API key, or pass it via the api_key parameter.

Get an API key at telnyx.com.

By default, langchain-telnyx uses the following OpenAI-compatible base URL:

https://api.telnyx.com/v2/ai/openai

You can override it either with the base_url parameter or with the TELNYX_API_BASE environment variable.

Example:

from langchain_telnyx import ChatTelnyx

chat = ChatTelnyx(
    api_key="YOUR_API_KEY",
    base_url="https://api.telnyx.com/v2/ai/openai",
    model="moonshotai/Kimi-K2.6",
)
