FAQ

Fugu balances quality and latency for everyday tasks like coding and chatbots. Fugu Ultra is the performance-focused version that maximizes answer quality for hard multi-step tasks by coordinating a deeper, fixed pool of expert agents, accepting higher latency and cost.

No. Fugu Ultra is not a monolithic foundation model. It is a learned orchestrator model that understands a request and constructs an adaptive workflow across a pool of specialist LLM agents, handling selection, coordination, verification, and synthesis.

Access is via a standard HTTP API. You can sign up on the website, obtain API keys, and use credits-based billing plans (Starter, Pro, Scale) to make calls compatible with the OpenAI API format.

No. Due to current restrictions, Fugu Ultra is not available for use in the European Union (EU) and European Economic Area (EEA) regions.

It is best suited for complex, high-value work where answer quality justifies higher latency, such as deep research, advanced security auditing, patent/legal analysis, and solving intricate reasoning problems.

Pricing is based on a monthly subscription for API credits (e.g., $19 for 15,000 credits). Credits are consumed based on usage, with detailed logs available. Plans scale from Starter to Pro to Scale.

The 4-step pipeline is: 1. Send request to API. 2. Fugu analyzes task. 3. Coordinates specialist agents. 4. Verifies outputs and synthesizes final answer.

For Fugu Ultra, the agent pool is fixed to ensure optimal performance. The standard Fugu model offers provider/model opt-out capabilities, but Fugu Ultra does not.

Key limitations include higher latency due to multi-agent coordination, higher cost from increased compute, and geographic restrictions preventing use in the EU/EEA.

Official benchmark scores (e.g., SWE Bench Pro 73.7%, GPQA-Diamond 95.5%) are reported on the website's benchmark page, though independent validation is pending.
