Comparison

FastMetal compared with the alternatives

There is more than one good way to use AI models over an API, and each has cases it genuinely wins. Here is an honest look at the four alternatives we get compared with most.

FastMetal vs OpenRouter

Two gateways with the same idea, built for different markets.

Claude API: FastMetal vs contracting Anthropic directly

Claude Code and the official SDK work unchanged. What differs is the contract and the invoice.

GPT-family models: FastMetal vs contracting OpenAI directly

Chat completions through the gateway. Features only the direct API has, through the direct API.

Models processed in Japan: FastMetal vs overseas hosting

For a set of models, prompts are processed entirely inside Japan.

FastMetal vs self-hosted LLMs (Ollama and friends)

Local inference and an API gateway solve slightly different problems.
