LocalAI vs Together AI
Both are alternatives to OpenAI API (ChatGPT). Here's how they stack up — verified facts, no spin.
Also searched as Together AI vs LocalAI — same comparison, one verdict.
LocalAI is open source (MIT) and Together AI is not (Proprietary (platform); serves open-weight models) — so the real question is whether you want to own the local & sovereign ai stack or rent it.
LocalAI
A drop-in, OpenAI-compatible API you host yourself.
LocalAI mirrors the OpenAI REST API — chat, embeddings, images, audio — but runs entirely on your own infrastructure across CPU or GPU. Point existing OpenAI-SDK code at it and nothing else changes.
Together AI
One API for the whole open-model universe — Llama, DeepSeek, Qwen and more.
Together AI is a hosted inference cloud for open models: one OpenAI-compatible API serving Llama, DeepSeek, Qwen, Mistral and dozens more, priced from about $0.05 to $9 per million tokens (Llama 3.3 70B around $0.88). The platform itself is commercial, but everything it serves is open-weight — so unlike a closed lab API, your exit is real: the same model you call today can run on your own GPUs tomorrow. A strong bridge for teams not ready to operate vLLM themselves.
Side by side
10 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

Weighing both against staying on OpenAI API (ChatGPT)? Is OpenAI API (ChatGPT) free? What it actually costs →
LocalAI
Strengths
- +True drop-in for OpenAI SDKs
- +Chat, embeddings, images, and audio in one server
- +CPU or GPU
Trade-offs
- −More moving parts to configure than Ollama
- −Throughput depends on your setup
Together AI
Strengths
- +Huge open-model catalog behind one OpenAI-compatible API
- +The models are open — migrating to self-hosting later is realistic
- +Often far cheaper than closed frontier APIs for comparable tasks
Trade-offs
- −A hosted US cloud — your prompts transit their infrastructure
- −Quality/cost varies widely across the catalog; you do the picking
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose LocalAI
if you want the source and the option to fork it, and you would rather run it on your own hardware, and your data should stay on machines you control.
Choose Together AI
if huge open-model catalog behind one OpenAI-compatible API.
Neither, yet
if both carry a real cost you should weigh first — more moving parts to configure than Ollama, and a hosted US cloud — your prompts transit their infrastructure. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
LocalAI vs Together AI — common questions
Is LocalAI a better fit than Together AI for local & sovereign ai?
It depends on what you are optimising for, and the honest split is this: LocalAI scores 90 to Together AI's 46 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Together AI earns its place on a different axis — huge open-model catalog behind one OpenAI-compatible API. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
LocalAI keeps its data local or in open formats, so leaving is an export rather than a negotiation. Together AI keeps your data on its own infrastructure, which is the part to plan for: confirm the export path before you commit, not when you are already trying to leave.
Is LocalAI free?
LocalAI: Free / self-host. The other side of this comparison, Together AI, is priced as Usage-based, ~$0.05–$9 per 1M tokens by model; intro credits for new accounts. "Free" here means no licence fee — if you self-host it you still pay for the server, and the running cost row above is our honest estimate of that.
Can I self-host LocalAI?
LocalAI can be self-hosted; Together AI cannot, so it stays on the vendor's infrastructure whatever you do.
Are LocalAI and Together AI both alternatives to OpenAI API (ChatGPT)?
Yes — both appear in our OpenAI API (ChatGPT) comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off OpenAI API (ChatGPT) and now choosing between the two replacements, which is a narrower and much easier question.
