What you get from Sail Research Free Credits for free
Overview
Sail Research runs inference for open-weight models through an OpenAI- and Anthropic-compatible API, plus Sailboxes: persistent Linux VMs billed only for the CPU, RAM and disk they actually use. Every account gets $5 in free credits each month, usable for either.
Free Tier Quotas & Limits
- The full $5 per month needs a payment method on the account; sign-up alone gives a smaller promotional credit.
- The credit resets monthly and covers both inference and Sailboxes.
- Accounts using only promotional credits are limited to a reduced number of requests per minute. Buying any credits removes that limit.
- When the balance hits $0, requests stop and Sailboxes pause. There are no surprise bills.
Key Free Models
Default-window prices per 1M tokens (input / output):
- DeepSeek V4.1 Flash (
deepseek-ai/DeepSeek-V4.1-Flash-1017): $0.09 / $0.30, about 55M input or 17M output tokens for $5. - GLM-5.3 Flash (
zai-org/GLM-5.3-Flash): $0.11 / $0.35, about 45M input or 14M output tokens. - Gemma 4 31B NVFP4 (
nvidia/Gemma-4-31B-IT-NVFP4): $0.14 / $0.40, about 36M input or 12M output tokens.
Cheaper "Balanced" and "Flex" windows stretch the credit further. Larger models such as Kimi K3 ($1.50 / $10.00) are available but use $5 quickly.

Used vCPU costs $0.015/hour, RAM $0.008 per GiB-hour and NVMe disk $0.0007 per GiB-hour. Sleeping boxes are not billed. Each new Sailbox costs $0.01 on the Free plan.
