Who we are

Hunan Pufan Information Technology Co., Ltd. is an IT company focused on AI infrastructure and software services, registered at Room 1001-410, Building 1, No. 41 Yannong Road, Changsha High-Tech Development Zone.

Our brand, Pufan AI TokenHub, is a Chinese LLM token aggregation platform: it consolidates model capabilities scattered across vendors behind a single OpenAI-compatible endpoint, so developers can reach DeepSeek, Qwen, Kimi, Doubao, Zhipu AI and every other major Chinese LLM with one API key and one SDK.

We believe model selection should be a business decision, not an engineering burden. As upstream vendors iterate constantly and prices and availability keep shifting, it makes more sense to pull "which model, how to connect, at what cost" out of application code and let a stable aggregation layer absorb that complexity.

What we do

  • Unified access layer: OpenAI-compatible protocol; migration is a Base URL change with zero application code changes.
  • Multi-vendor routing: weighted routing and failover based on model capability, price and live availability, so a single vendor outage does not take down requests.
  • Aggregated token billing: dual-track billing with pay-as-you-go and Token Plan subscriptions, credits that work across models, and itemised usage records.
  • Coding Plan: dedicated quotas and context policies for coding agents such as Claude Code and Codex.
  • Dedicated line: exclusive channel, high-concurrency guarantees and an SLA, plus custom integration and self-hosted deployment.
PRINCIPLES

Three principles we work by

1
Predictable billing

Pay first, consume later; service stops when credit runs out and plans never auto-renew. No pre-ticked boxes, no silent renewals.

2
Usage is traceable

Every request logs its model, token count and charge, exportable by time range, model or sub-account for reconciliation.

3
Failures are visible

Upstream failures fail over to backup channels automatically; platform status and incident history are public, and we proactively notify you of major incidents.
