Pricing
Alien routes inference to the AI service in your customer's cloud. The customer pays the cloud provider for the tokens, and Alien charges a small management fee. See Pricing for Alien's current rates.
Global-endpoint rates. Last verified: August 2026.
Token Pricing
Inference is billed per token, priced per model. Output costs several times more than input on every provider.
| Model | Provider | Input | Output |
|---|---|---|---|
| Claude Sonnet 4.5 | AWS, GCP, Azure | $3.00 per million | $15.00 per million |
| GPT-OSS 120B | AWS | $0.15 per million | $0.60 per million |
Claude costs the same wherever it is served — Anthropic sets the rate and the clouds resell it. The figures above are the global-endpoint rate; pinning a model to one region adds roughly 10% on every cloud. Model choice still moves the bill far more than cloud or region does: the two rows above are the same workload more than 20× apart.
Infrastructure Pricing
| Platform | Standing charge |
|---|---|
| AWS | None. Bedrock is an account-level API with nothing provisioned. |
| GCP | None. Enabling the Vertex AI API is free. |
| Azure | None. The AI Foundry account and its deployments bill per token, not per hour. |
An AI resource that nothing calls costs nothing, on all three clouds.
Example: 5M Input + 1M Output Tokens/month
A support assistant handling about 5,000 conversations a month, at roughly 1,000 input and 200 output tokens each.
| Model | Input | Output | Monthly |
|---|---|---|---|
| Claude Sonnet 4.5 | $15.00 | $15.00 | $30.00 |
| GPT-OSS 120B | $0.75 | $0.60 | $1.35 |
Same traffic, same code, one line different in the request.
Local and Kubernetes
No cloud charges. Both use a bring-your-own-key binding, so you pay your provider directly at their published rates.
Free Tiers
- AWS: no free tier for Bedrock on-demand inference.
- GCP: new-account credits apply to Vertex AI; there is no always-free inference allowance.
- Azure: new-account credits apply to Foundry; there is no always-free inference allowance.
