Question 1

What is Fusion Code AI?

Accepted Answer

Fusion Code AI is a developer-first, unified AI gateway and CLI. It provides drop-in OpenAI-compatible access to frontier intelligence—including DeepSeek-V4-Flash-0731, GLM 5.3 Flash, and MiniMax-M2.7—powered by sub-millisecond Cloudflare edge routing and automatic prompt caching.

Question 2

How much does DeepSeek-V4-Flash-0731 cost on Fusion?

Accepted Answer

DeepSeek-V4-Flash-0731 is priced at $0.010 per 1M input tokens, $0.018 per 1M output tokens, and only $0.0014 per 1M cached prompt tokens. This is over 90% cheaper than OpenAI GPT-4o Mini or Claude 3.5 Haiku.

Question 3

Are there any monthly subscriptions or recurring fees?

Accepted Answer

No. Fusion operates 100% on a Pay-As-You-Go prepaid credit balance. There are zero monthly commitments, no recurring subscription charges, and your credits never expire.

Question 4

Can I use Fusion with Cursor, Zed, Cline, or Aider?

Accepted Answer

Yes. Fusion is 100% OpenAI-compatible. In Cursor, Zed, Cline, Roo Code, or Aider, simply set your API Base URL to https://api.fusioncode.app/v1 and enter your Fusion API key. All frontier models and prompt caching work immediately with zero custom code.

Question 5

How do I achieve up to 95% cache hit rates?

Accepted Answer

Fusion's gateway engine incorporates prefix-stable context compaction. In interactive coding loops where project file trees and earlier conversation history repeat, the gateway aligns byte-identical prefixes so requests hit the edge KV cache, delivering near-instant responses and up to 90%+ cost savings.

Question 6

What payment methods are supported?

Accepted Answer

We support global and local payment methods: USDC and USDT cryptocurrency (via Suby on Base), international credit and debit cards (Visa, Mastercard), and Myanmar local payments (KBZPay, WaveMoney, and AYA Pay).
