The LLM market is no longer just about raw model intelligence; it is about arbitrage. A new report from LONG AI, published November 3, 2026, reveals that multi-seller gateways are offering effective prices for major models like Claude Sonnet 5 and GPT-5.6 Sol that are an order of magnitude lower than official list prices. For example, Anthropic’s claude-sonnet-5, which lists at 13.39 CNY per million input tokens, can be accessed for as low as 0.603 CNY on the deepest discount tier. This represents a 0.45 zhe, or 4.5% of the original price. However, these are not guaranteed rates for every request; they represent the best available ask at a specific moment in time.

The Volatility of Secondary Quota Markets

The pricing structure described relies on a marketplace model where sellers list spare model quota. The platform dispatches requests to the best available ask based on price, load, and health, with automatic failover. This means the deepest discount is a snapshot of the most aggressive seller currently active. For instance, the 0.45 zhe tier for Claude Sonnet 5 is supported by only 7 sellers, while GPT-5.6 Sol’s 0.24 zhe tier has 11 sellers. If you build your application assuming these rock-bottom prices are permanent, you will likely face unexpected cost spikes when the best-tier sellers withdraw their asks or when demand shifts. The data, captured as of November 4, 2026, tracks 352 model profiles across 49 vendors, with only 190 currently listed for sale.

Model Performance vs. Price Tiers

The report clarifies that these discounts do not come from using a weaker, distilled version of the model. The API is OpenAI-compatible, allowing developers to point their base URL to the gateway while retaining the full capability of the underlying model. The cost reduction stems from reselling idle quota, bulk purchasing, and regional pricing differences. For developers, this creates a new layer of infrastructure management: you are no longer just choosing between vendors, but between specific quota tiers. DeepSeek V4 Flash remains the cheapest general-purpose option at 1 zhe (10%) of its list price, but for high-context coding tasks, the arbitrage on Claude and GPT models offers significant savings if you can tolerate the routing complexity.

Key Takeaways

  • Effective prices on gateways can be significantly lower than official list prices, with discounts reaching 0.45 zhe for Claude Sonnet 5.
  • Discounts are volatile; the deepest tier is a best-case scenario dependent on current seller availability.
  • The API is OpenAI-compatible, allowing easy integration without changing model logic, only routing.
  • Seller count matters: A model with 11 sellers offers more stability than one with 7, even if the price is similar.

The Bottom Line

While the price arbitrage is real, the dependency on volatile seller availability makes these gateways better suited for cost-sensitive, non-critical workloads than for production systems requiring guaranteed SLAs. Treat the deepest discounts as a bonus, not a baseline.
