> Root index: https://developers.telnyx.com/llms.txt · AI index: https://telnyx-openapi-ng.s3.us-east-1.amazonaws.com/llms/ai.txt · Full content for this subsection: https://telnyx-openapi-ng.s3.us-east-1.amazonaws.com/llms/ai/inference-full.txt

## Models

- [Models](https://developers.telnyx.com/docs/inference/models.md): Open-source 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 four regions across three 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 & 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.
- [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.
- [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
