How this service works
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.
Output
Returns an OpenAI-compatible chat completion object containing the assistant's reply text and the name of the serving model (nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16). The response is only billed (0.001 USDC) if the answer is successfully returned; failed calls are not charged.
Example use cases
Arithmetic calculation via small LLM
“I need a quick calculation: what is 15% of 4,892 plus 37.5? Ask the Taifoon Nemotron Nano model and keep the reply under 100 tokens.”
Short creative text generation
“Use the Taifoon Nano model to write me a two-sentence product tagline for a reusable water bottle brand called ClearFlow — limit the response to 150 tokens.”
Simple factual Q&A in an agent pipeline
“Send this to the Taifoon Nemotron chat endpoint: 'Explain in one paragraph what a binary search algorithm does' — cap the answer at 300 tokens.”
Technical details
Endpoint
POSThttps://coord.taifoon.dev/v1/x402/class/inference.metered?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cheap, pay-per-call LLM inference on a small (4B parameter) open model without provisioning your own GPU, especially for short conversations, arithmetic, or basic text tasks where recent factual knowledge is not required. It is ideal for agent pipelines that need cost-predictable inference at $0.001 per call with the guarantee of no charge on failure. Prefer a larger hosted model if the task demands broad world knowledge, long context, or high accuracy on complex reasoning.
Side effects
- max_tokens exceeds 700 — request rejected
- messages array is empty or missing required role/content fields
- total token budget (prompt chars/4 + max_tokens) exceeds 5,000 — request rejected
- payment via x402 fails — no inference performed
- model unavailable or GPU offline — service error returned without charge
- malformed JSON body — 400-level error
