# Telnyx AI: Inference — Documentation Index > Inference documentation within the AI section of the Telnyx developer docs (https://developers.telnyx.com). > This file: https://developers.telnyx.com/docs/development/llms/ai-inference-llms-txt.md · Root index: https://developers.telnyx.com/llms.txt ## Inference - [Models](https://developers.telnyx.com/docs/inference/models.md): Open-weight LLMs available through the Telnyx Inference API, hosted on Telnyx GPUs and accessible via an OpenAI-compatible Chat Completions endpoint. - [Regions & Availability](https://developers.telnyx.com/docs/inference/models/regions.md): GPU regions and routing behavior for the Telnyx Inference API, spanning five regions across four continents with automatic nearest-region routing. - [Pricing](https://developers.telnyx.com/docs/inference/models/pricing.md): Pay-per-token pricing for the Telnyx Inference API with no minimums or commitments. See current per-model rates and available regions. ## Data Residency - [Data Residency & Compliance FAQ](https://developers.telnyx.com/docs/inference/data-residency.md): How Telnyx handles processing location, storage at rest, self-hosted vs third-party STT/TTS/LLM providers, data retention, and model training across the Inference API and Voice AI Assistants. ## Integrations - [Integrations](https://developers.telnyx.com/docs/inference/integrations.md): Use the OpenAI-compatible Telnyx Inference API with popular AI frameworks by swapping base_url and api_key — works with LangChain, LlamaIndex, and others. - [OpenAI Migration](https://developers.telnyx.com/docs/inference/openai.md): Migrate from the OpenAI API to the Telnyx Inference API by changing two environment variables and a model name — no code rewrites required. - [Anthropic Migration](https://developers.telnyx.com/docs/inference/anthropic.md): Migrate from the Anthropic API to the Telnyx Inference API by changing the base URL and passing your Telnyx API key in an Authorization header — no code rewrites required. - [LangChain](https://developers.telnyx.com/docs/inference/langchain-integration.md): Use Telnyx Inference as an LLM provider in LangChain. Configure ChatOpenAI with the Telnyx base URL to power chains, agents, and retrieval pipelines. - [LlamaIndex](https://developers.telnyx.com/docs/inference/llama-index.md): Use Telnyx Inference with LlamaIndex to build RAG applications. Configure the OpenAI-compatible client to index documents and run retrieval-augmented queries. - [CrewAI](https://developers.telnyx.com/docs/inference/crewai.md): Integrate Telnyx Inference with CrewAI to build multi-agent workflows. Use Telnyx as the LLM provider for autonomous agents and crew orchestration. - [LiveKit](https://developers.telnyx.com/docs/inference/livekit.md): Integrate Telnyx STT, TTS, and LLM services into LiveKit agents using the Telnyx LiveKit Plugin. ## Tutorials - [Inference API](https://developers.telnyx.com/docs/inference/getting-started.md): Quickstart for the Telnyx Inference API. Get an API key, send your first chat completion request, and explore models for text, embeddings, and audio. - [Function Calling](https://developers.telnyx.com/docs/inference/functions.md): Use function calling with the Telnyx Inference API to let LLMs invoke your tools. Define JSON schemas, handle tool calls, and return structured outputs. - [Streaming and Parallel Calls](https://developers.telnyx.com/docs/inference/streaming-functions.md): Stream tool calls and run multiple functions in parallel with the Telnyx Inference API. Handle partial JSON, deltas, and concurrent tool invocations. - [JSON Mode and Beyond](https://developers.telnyx.com/docs/inference/json-mode.md): In this tutorial, you'll learn how to: Start building on Telnyx today. - [Fine Tuning](https://developers.telnyx.com/docs/inference/fine-tuning.md): Fine-tune open-source models on the Telnyx Inference platform. Upload a training dataset, run a job, and deploy your customized model for inference. - [Audio Language Models](https://developers.telnyx.com/docs/inference/audio-language-models.md): Use Telnyx audio language models for speech-to-text, translation, and audio understanding. Send audio files or streams and receive transcripts and analysis. - [PR Reviewer - Github Action](https://developers.telnyx.com/docs/inference/pr-reviewer.md): Telnyx Inference tool for automatically reviewing Pull Requests at GitHub - [AI SMS Outfit Recommender with OpenMeteo](https://developers.telnyx.com/docs/inference/ai-outfit-recommender.md): Telnyx Inference + AI offering SMS outfit recommendations using ## API Reference (Inference) ### OpenAI Chat - [Create a chat completion (OpenAI-compatible)](https://developers.telnyx.com/api-reference/openai-chat/create-a-chat-completion-openai-compatible.md): Chat with a language model.
