Intern-InternLM InkStone Token Plan: monthly free tokens during the preview

What the preview includes

• Eligibility: Users who register for the Intern-InternLM InkStone preview. The Shanghai AI Laboratory announcement says each user receives free tokens monthly during the preview.
• Billing unit: Ink Points. The console says one point can cover up to about 50 million tokens for DeepSeek-V4-Flash; the exchange varies by model and is not 1:1.
• Preview-free models: Intern-S2, Atria-Dawn-Preview, and Agents-A1 are marked temporarily free in the official documentation.
• Other models: DeepSeek-V4-Flash / Flash-Vision / Pro, GLM-5.3, Kimi-K2.6, MiniMax-M3, and Qwen3.8-27B use the model-specific Ink Point rates.
• API endpoints: OpenAI-compatible https://discovery-api.intern-ai.org.cn/v1 and Anthropic-compatible https://discovery-api.intern-ai.org.cn.
• Expiry: The preview has no published end date. One-time Ink Points clear at 24:00 on their expiry date; monthly grants follow the calendar-month cycle.

How to use it

1. Open the InkStone web app and register.
2. Enter the Research Models / Token Plan area, claim the preview points, and create an API key. The full key is shown only once, so store it safely.
3. Use the compatible Base URL and key in Claude Code, Codex, WorkBuddy, or another supported client, or use the web chat. Confirm model IDs in the console.

Check the Token Plan console, the Shanghai AI Laboratory announcement, and the related community discussion. Availability, quotas, and model pricing may change during the preview.
