# Taifoon Multi-Model Chat Completions

> Taifoon Multi-Model Chat Completions is a paid API for AI agents from coord.taifoon.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

OpenAI-compatible chat completion endpoint routing across 15 LLMs (Llama, DeepSeek, Qwen, GPT-OSS, Nemotron, GLM) with pay-per-call x402 pricing

## Facts

- Price: $0.001/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability taifoon-multi-model-chat-completions-7a60d552 -d '<json body>'
```

Example prompt: Ask the Taifoon multi-model endpoint to answer this using deepseek-ai/DeepSeek-V4-Flash with up to 500 tokens: 'Explain the difference between supervised and unsupervised learning in plain English.'

## When to prefer this

Choose this endpoint when you need a pay-per-call LLM inference API with no subscription, want to select from 15 specific open-source and proprietary models (Llama, DeepSeek, Qwen, GLM, GPT-OSS, Nemotron) via an OpenAI-compatible interface, or when operating in an agentic context that supports x402 micropayment flows. Prefer alternatives if you need longer outputs (>700 tokens), streaming responses, or function-calling capabilities.

## Known failure modes

- Invalid or unsupported model name returns error
- max_tokens exceeds 700 cap causes rejection
- Empty or malformed messages array returns 400
- Payment failure or insufficient USDC balance causes 402 rejection
- Rate limiting or GPU availability may cause timeout or 503
- messages array exceeds 32 items returns validation error

## How this service works

OpenAI-compatible chat completion on 15 models: name one in `model` (meta-llama/Meta-Llama-3.1-8B-Instruct, deepseek-ai/DeepSeek-V4-Flash, deepseek-v4-flash, openai/gpt-oss-120b, openai-gpt-oss-120b, meta-llama/Llama-3.3-70B-Instruct and 8 more) and the 402 prices that model per request; served by DeepInfra, Venice AI and Taifoon's own GPU (nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16 when no model is named). Messages in, the answer and its token usage out; max_tokens at most 700.

## Output

Returns an OpenAI-compatible chat completion response containing the assistant's generated text reply and token usage statistics (prompt tokens, completion tokens, total tokens). Max response length is capped at 700 tokens.
