Together AI Alternatives in 2026: 10 Gateways Compared
If you are leaving Together AI over billing — wanting a hard ceiling rather than a bill settled afterwards — SuperbAPI is the closest fit: prepaid credit, no subscription, and a budget cap per key. If you are leaving over what Together AI covers, Fireworks AI is the nearest substitute, being a platform that hosts and serves open-weight models itself. Both, and eight more, are ranked below — with a straight account of where Together AI is still the better answer.
Why do people look for Together AI alternatives?
The usual reason is coverage. Together is excellent at open-weight models and does not aim to be your route to the frontier closed models, so teams that started there often end up holding a second account for Claude or Gemini — which is exactly the fragmentation a gateway is supposed to remove. The other reason is billing: usage is invoiced after the fact, which is hard to cap.
The 10 alternatives at a glance
| # | Gateway | Billing | Best for |
|---|---|---|---|
| 1 | SuperbAPI | Prepaid credit, no subscription | One prepaid wallet across every major model, with per-key budget caps |
| 2 | Fireworks AI | Postpaid, pay-as-you-go | Low-latency open-model serving with production tuning |
| 3 | Groq | Postpaid, with a free tier | The fastest tokens per second on a curated open-model set |
| 4 | OpenRouter | Credits, plus bring-your-own-key | The widest model catalogue behind a single OpenAI-compatible key |
| 5 | Replicate | Per-second compute | Image, video and audio models, plus custom model deploys |
| 6 | Portkey | SaaS or self-hosted; you bring provider keys | Routing, caching, guardrails and observability over your own keys |
| 7 | LiteLLM | Open source, self-hosted; paid enterprise tier | A self-hosted proxy normalising many providers to one format |
| 8 | Helicone | Open source or cloud; you bring provider keys | Logging, tracing and cost attribution for LLM calls |
| 9 | Eden AI | Usage plus a platform fee | Aggregating AI beyond LLMs — OCR, speech, translation, vision |
| 10 | AI/ML API | Subscription plus usage | A large single-key catalogue on a subscription plan |

The 10 alternatives in detail
1. SuperbAPI
An independent, prepaid, OpenAI-compatible aggregator: one balance, one base URL, and text, code, image and video models behind a single key.
You top up once and every call draws down that balance at the model's own rate — no subscription, no monthly minimum, and no invoice arriving after the fact. Keys can be scoped to specific models and given a budget cap, so a test key cannot spend production's money, and credit is valid for 12 months. Requests fail over to another upstream serving the same model, and a call that ultimately fails bills nothing.
2. Fireworks AI
An inference platform focused on serving open-weight models fast, with fine-tuning and enterprise deployment options.
Same category as Together AI — a platform that hosts and serves open-weight models itself — so the switch is a like-for-like one. The difference that matters is billing: postpaid, pay-as-you-go, against Together AI's postpaid, pay-as-you-go.
3. Groq
Inference on custom LPU hardware, offering exceptional tokens-per-second on a deliberately narrow set of open models.
Same category as Together AI — a platform that hosts and serves open-weight models itself — so the switch is a like-for-like one. The difference that matters is billing: postpaid, with a free tier, against Together AI's postpaid, pay-as-you-go.
4. OpenRouter
The gateway that popularised one API key for every model, and still the broadest catalogue in the category.
A different shape of product from Together AI: one key and one balance across many vendors' models. Worth the move only if what you actually need is the widest model catalogue behind a single openai-compatible key — otherwise it solves a problem you do not have.
5. Replicate
A platform for running a very large community catalogue of models, strongest well outside text — diffusion, video, speech — and for deploying your own.
A different shape of product from Together AI: an aggregator reaching well beyond text, into image, video and audio. Worth the move only if what you actually need is image, video and audio models, plus custom model deploys — otherwise it solves a problem you do not have.
Also worth knowing
These are further from what Together AI does, but each is the right answer to a specific question:
- 6. Portkey — Routing, caching, guardrails and observability over your own keys. SaaS or self-hosted; you bring provider keys.
- 7. LiteLLM — A self-hosted proxy normalising many providers to one format. Open source, self-hosted; paid enterprise tier.
- 8. Helicone — Logging, tracing and cost attribution for LLM calls. Open source or cloud; you bring provider keys.
- 9. Eden AI — Aggregating AI beyond LLMs — OCR, speech, translation, vision. Usage plus a platform fee.
- 10. AI/ML API — A large single-key catalogue on a subscription plan. Subscription plus usage.
Where Together AI still wins
Running open models at volume. If your workload is mostly Llama, Qwen or DeepSeek and you care about tokens per second and cost per million, Together is a stronger answer than any aggregator, and fine-tuning plus dedicated capacity is something a pure router structurally cannot offer. Keep it for that and put a gateway in front for everything else.
How to migrate off Together AI
Together is OpenAI-compatible, so the client change is the base URL and key. The real decision is whether to move at all: if you are there for fine-tuned or dedicated models, those do not exist elsewhere. The common pattern is to keep Together for the open-model workload and route the closed frontier models through a gateway.
Together AI alternatives: common questions
What is the best Together AI alternative?
It depends what you use it for. For reaching closed frontier models such as Claude and Gemini alongside open ones, an aggregator like SuperbAPI covers more ground. For raw open-model throughput, Fireworks AI and Groq are the direct competitors.
Does Together AI serve Claude and GPT?
Together specialises in hosting open-weight models itself. Reaching the closed frontier models generally means a second account or an aggregator that routes to them.
Can I keep my fine-tuned Together models if I switch?
No. A model fine-tuned and hosted on Together exists on Together. That is a genuine reason to keep the account rather than migrate away from it.
Where SuperbAPI fits
SuperbAPI is an independent, prepaid, OpenAI-compatible aggregator: one wallet, one base URL, and text, code, image and video models behind a single key. Keys can be scoped to specific models and capped with a budget, so the balance is a hard ceiling rather than a starting point.
SuperbAPI is an independent aggregator and is not affiliated with, endorsed by, or partnered with any model owner. Third-party product names are used nominatively to describe compatibility and routing. Comparisons reflect our understanding at publication and may change.
