OpenAI-compatible chat completion on NVIDIA Nemotron-3-Nano-4B (nvidia/NVIDIA-Ne
OpenAI-compatible chat completion on NVIDIA Nemotron-3-Nano-4B (nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16, base weights), a small open model served from Taifoon's own GPU: short chat, text and arithmetic, not facts about recent technology. 0.001 USDC per request of up to 5,000 tokens (prompt chars/4 + max_tokens, max_tokens ≤ 700). Send { messages, max_tokens }. The answer is checked before you are charged: a failed answer is not charged.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
