Precision is what each provider reports. Some models ship in fp8 or fp4, so a low number alone does not mean a cut-down copy. If a provider runs lower precision than the release, its answers can differ from the version you tested. "unknown" means the provider does not say.

Where these prices come from
Prices, precision, context, uptime and throughput are read live from OpenRouter's public endpoint list for z-ai/glm-5.3-flash each time this page loads, so they match what the providers charge today. If that request fails, the page shows the snapshot taken when it was built, and says so. Prices are per million tokens in US dollars, before any provider discounts or free tiers.
