About Reflex Hub

What this site is

Reflex Hub is an independently maintained project of developer tools focused on LLM API cost estimation, model-spec comparison and AI tool selection. We want developers to understand published model pricing, the conditions behind cost calculations, and usage limits — with verifiable sources behind every decision.

The site currently offers: an LLM API cost calculator, a model pricing & spec library, a model comparison tool, an AI tool directory, a prompt library (Chinese prompts) and an AI literacy rank test. All tools are free and need no account.

Data sources and calculation method

· Model prices, specs and related product information reference vendors' public materials wherever possible; each record carries a source link and a verification date, as shown on the corresponding page;
· The cost calculator estimates charges from call volume, input/output tokens, cache hit rate and billing assumptions; estimates do not equal a provider's actual invoice and do not constitute purchase advice;
· Where a source cannot be verified or is not yet updated, the limitation is stated explicitly instead of presenting unknowns as facts; prices follow the vendors' official pages and may change;
· The full data rules (billing units, tiers, reference rates, verification-date semantics, unknown-value handling) are documented in the pricing methodology.

Independence and commercial relationships

Reflex Hub is an independent product and does not represent any model vendor or third-party tool provider. Third-party names and trademarks (DeepSeek, GLM, Kimi, Qwen, etc.) belong to their respective owners; this site is a third-party data compilation with no vendor affiliation. If pages ever contain affiliate or sponsored links, the commercial relationship will be disclosed next to the recommendation, and official information, verifiable data and editorial judgment will be kept distinct.

Privacy and usage

No account is required; every tool computes locally in your browser. Analytics (Cloudflare Web Analytics — cookieless, no personally identifiable information) is currently not enabled on the pages; if it is ever enabled in the deployment configuration, it will be used for anonymous traffic statistics only and this statement will be updated. See the privacy policy for local storage, third-party links and affiliate handling, the affiliate disclosure for promotion principles, and the terms of use for usage limits.
