Thank you for supporting FC Agent Sandbox. To provide a runtime environment that better fits agent development in the AI era, Function Compute (FC) is switching FC Agent Sandbox to a new billing model. Scenario-based editions and significantly lower prices help reduce the computing costs of your AI workloads.
Change schedule
From 00:00 (UTC+8) on July 31, 2026, FC Agent Sandbox will gradually switch to the new billing model on a region-by-region basis.
Key changes
For details about the new FC Agent Sandbox pricing, see Pay-as-you-go.
Three scenario-based computing editions: match on demand, pay with precision
To meet the differing needs of business scenarios such as compute-intensive and latency-sensitive workloads, FC Agent Sandbox introduces the Eco, Std, and Pro editions. Pricing is tiered by computing quality of service (QoS), which enables on-demand matching and precise billing.
Edition | Computing features | Typical scenarios | Hibernation capability |
Eco (Economy) | Ultra-low barrier: Allows computing power fluctuations. | Ideal for AI startups, individual debugging, and Tool Use validation. | Deep hibernation |
Std (Standard) | General and balanced: Relatively stable performance with low-latency responses, ready for production environments. | Ideal for high-concurrency consumer-facing agents, complex computing, and large-scale sampling and reinforcement learning (RL) simulation. | Deep hibernation |
Pro (Professional) | Guaranteed resource delivery: A dedicated resource pool keeps computing power stable, and wake-up from shallow hibernation takes 1 ms. | Ideal for production-grade RL training, quantitative finance, and long multi-agent chains. | Deep and shallow hibernation |
Simplified billing with significantly lower prices
FC Agent Sandbox is switching to an intuitive pay-as-you-go model. Charges are based on the unit price of computing resources multiplied by the computing run duration, so your bills are simple to calculate and easy to understand. Unit prices have also been slashed, and the savings are passed on to you. This significantly reduces the cost of running workloads at scale and frees AI innovation from budget constraints.
Applicability and transition
Applicable to: The new pricing applies only to users who access FC Agent Sandbox through the E2B SDK.
Migration path: If you previously used Sandbox Functions or AgentRun Sandbox and want to use the new pricing, switch to accessing FC Agent Sandbox through the E2B SDK.
Automatic upgrade: Shallow hibernation is enabled by default. Existing FC Agent Sandbox customers who access the service through the E2B SDK are therefore automatically moved to the Pro edition after the new pricing takes effect.
