Free aggregator routes

These are the aggregator routes recorded in the current or last published catalog. Each route keeps its exact model ID and thinking information.

The exact route uses TokenHarbor's free allowance and is not billed; availability, quotas and model access remain account-dependent.

Limits above: TokenHarbor. Available gateway routes are listed below.

TokenHarbor explicitly states at https://www.tokenharbor.ai/blog/deepseek-v4-flash-0731-vs-pro-new-agent-benchmarks-explained that both deepseek-v4-flash and deepseek-v4-flash:free serve Flash 0731. This establishes the same advertised dated model as the supplied Infron 0731 entry and https://huggingface.co/deepseek-ai/DeepSeek-V4-Flash-0731. The unchanged runtime ID does not identify the original preview. Undated Infron and OpenCode identities are not merged.
