What is Faster Claude

Faster Claude lets you run your Claude Code sessions on Cursor Composer 2.5 through an Anthropic-compatible endpoint. You point your existing setup at us and keep every tool, command, and habit you already have. Nothing about how you work changes. Your sessions just run faster and cost less.

The model: Cursor Composer 2.5 (fast)

Cursor Composer 2.5 is a frontier coding model built for agentic work: long-running tasks, multi-file edits, and reliable tool use. We serve the fast variant of it, which is the only model we offer. There is no model picker, and you never have to think about which engine to choose.

What the fast variant gives you:

• High generation speed. It keeps the same intelligence as the standard tier but runs at much higher throughput, so the first tokens arrive sooner and long edits finish faster. This matters most in agentic loops, where a session makes many calls back to back.
• Strong agentic behavior. Cursor Composer 2.5 is a large step up from Composer 2. It sustains focus on long tasks, follows complex instructions more reliably, and calibrates its effort well, which makes it pleasant to drive from Claude Code.
• Built for coding. It is trained for real codebases and the kinds of edit, refactor, and tool-call patterns coding agents produce.

How it works

You change one environment variable. Your Claude Code client keeps speaking the same Anthropic API it always has. We translate that to Cursor Composer 2.5 behind the scenes and stream the response back.

• Drop-in. Compatible with the Anthropic API your tools already speak.
• Metered. Pay only for what you use. No subscription, no seat fees, no lock-in.
• Unchanged workflow. Same CLI, same editor integration, same commands.

Where it runs

We expose two endpoints that reach the same engine:

• United States (api.fasterclaude.com) is the global default.
• Singapore (api-sg.fasterclaude.com) is a closer entry point for users in Asia, which cuts the round-trip latency to first token.

Both share one account, one balance, and one set of API keys. You only change the base URL to switch between them. Pick the one nearest you.
