Fireworks AI alternatives
Fireworks AI is a fast inference host for mainstream open-weight models. The alternatives below are the hosts it is usually compared with, and what MagmaRouter does differently: a short line of uncensored models that all call tools, per token, with a hard spend cap on every key.
What Fireworks AI is, and where it stops
Fireworks serves open-weight models quickly and supports custom deployments, but the serverless catalogue is curated to mainstream instruct models, so an uncensored finetune generally means renting dedicated capacity.
Other options people compare with Fireworks AI
| Option | What it is |
|---|---|
| Together AI | Large catalogue of mainstream open-weight models, per token on serverless or on dedicated endpoints, plus fine-tuning. |
| DeepInfra | One of the cheaper per-token hosts for open-weight models, with a wide catalogue that changes as models are added and retired. |
| Groq | Very fast inference on its own LPU hardware, over a short list of models compiled for it. |
| Baseten | Per-token Model APIs over a short list of mainstream open models, and dedicated deployments billed by the minute. |
| Cerebras | Very fast inference on wafer-scale hardware, over two shared models (GPT OSS 120B and Qwen 3.8 27B) plus dedicated capacity. |
| Novita AI | Low-cost open-weight host, including some uncensored builds, and an upstream that gateways route to. |
| OpenRouter | A router over many providers: one key and one bill for hundreds of models, each served under its provider's policy. |
| Featherless | Flat monthly subscription over tens of thousands of open Hugging Face models, hundreds of them abliterated or uncensored, hosted by Featherless itself. |
Weighing the two directly? MagmaRouter vs Fireworks AI puts pricing, endpoints, spend caps and model policy side by side, checked against Fireworks AI's own site.
What MagmaRouter carries instead
MagmaRouter sells 6 uncensored models on one OpenAI-compatible endpoint, every one able to call tools. Ordered for this particular job rather than by a single ranking: GLM 5.3 Flash Xploded leads because it is the cheapest of the set on output at $1.00 per million tokens.
| Model | Context | In | Out | Tools |
|---|---|---|---|---|
| GLM 5.3 Flash Xploded glm-5.3-flash-xploded |
1.05M | $0.30 | $1.00 | Yes |
| DeepSeek V4.1 Flash Xploded deepseek-v4.1-flash-xploded |
1.05M | $0.30 | $1.50 | Yes |
| MiMo V2.6 Flash Xploded mimo-v2.6-flash-xploded |
1.05M | $1.00 | $2.00 | Yes |
| Qwen3.8 27B Fast Xploded qwen3.8-27b-fast-xploded |
524k | $1.50 | $5.00 | Yes |
Switching takes one base URL
Anything that speaks the OpenAI chat completions format works unchanged. Point it here, use a MagmaRouter key, and name the model from the table.
curl https://api.magmarouter.com/v1/chat/completions \ -H "Authorization: Bearer sk-mr-..." \ -H "Content-Type: application/json" \ -d '{ "model": "glm-5.3-flash-xploded", "messages": [{"role": "user", "content": "Hello"}] }'
FAQ
Is MagmaRouter actually uncensored, or does it just say so?
MagmaRouter does not moderate requests. It prices the call, holds the money against your key cap and passes the request to the model. What comes back is whatever that model does: an uncensored build refuses far less than a frontier model but can still decline, and only an abliterated build has the refusal direction removed outright. Neither tag is a promise that any given answer will arrive.
What does it cost compared with Fireworks AI?
You pay per token at the rates in the table above, with no subscription. $0.30 in and $1.00 out per million tokens for GLM 5.3 Flash Xploded.
Can I cap what a key is allowed to spend?
Yes, and the cap is enforced before the request goes upstream rather than reconciled afterwards. The reply cannot physically cost more than the hold placed before it was sent.
Will it work with my existing client?
If the client takes an OpenAI-compatible base URL, yes: point it at https://api.magmarouter.com/v1 with a MagmaRouter key. Claude Code and the Anthropic SDKs use the Anthropic format, which is served too.
