About the product
Balance Top-Up | API KEY | Sakana Fugu Ultra
⚠️ This is not an official Sakana AI key — it's an API aggregator (many models) at below-official prices
Access to Fugu Ultra — Sakana AI's flagship model — through a single API key and shared balance. Deep reasoning and a 1M-token context: an entire codebase or a book fits in one session. Pay only for actual requests: your USD balance never expires, no subscriptions, no monthly fees. Fully OpenAI-compatible — change only the base URL and key, the rest of your code stays untouched.
💰 Prices per 1M tokens (input / output)
• Fugu Ultra — $0.77 / $4.64
💸 The same Fugu Ultra 5–6× cheaper than direct or via OpenRouter. One balance instead of a dozen separate subscriptions and keys.
