OpenAI-compatible APIs over 24 models, GLM 5.3 Flash, Kimi K3 and MiniMax M3 among them, with $2 of free credit for every user — $4 with the vendor’s invite code — at 5 requests a minute until a first deposit
The page this row is verified against names no free model, so the column stays empty; callable ids, where the row has them, are under Connect.
The Model APIs page answers its FAQ “Do you offer a free trial for users?” in the page’s data rather than its text: every user receives $2 “in free credits. New accounts using the invite code” HPCAI-MAPI get $4, and “Supplies are limited”. The console’s welcome message, shipped in the same page, reads “Free credits have been added to your account — start calling open-source models right away.” and “Make your first deposit to unlock higher RPM limits.” The keyless model list gives the L0 tier, an account before its first deposit, 5 requests and 2M tokens a minute on 23 of its 24 models (DeepSeek V4 Pro gets 0), and the rate-limit docs say the move to L1 “is triggered by your first deposit rather than by spending”. The credit buys list prices, GLM 5.3 Flash at $0.15 in and $0.50 out per million tokens and Kimi K3 at $3 and $15. No page read asks for a card before the credit is spent, and none gives it an expiry. Read 2026-09-17
