SiliconFlow

Truly Free

Inference platform with a mix of free and paid open-source models, plus a small starter credit for new signups. SiliconFlow's own docs confirm free models exist ("$0" calls with fixed rate limits) after identity verification, but the exact free-model list isn't published on the public pricing page and requires a login to view — treat rate limits/model names as unconfirmed until verified in your own dashboard.
