Rent a Cloud GPU with Hermes Agent or OpenClaw

说明与用途

CPU 机器人通过 Hermes Agent 或 OpenClaw 在 Vast.ai 上租用 GPU 实例，使用 SSH 运行任务，下载结果后销毁实例，控制成本。

问题

Bots running on CPU servers need GPU compute for specific jobs but lack GPU resources locally.

结果

A single chat message can trigger a full GPU rental cycle: the bot quotes, rents, runs, downloads, and cleans up an instance in under 4 minutes, costing only $0.007 for the test render.

工作流

• Describe job and limits to bot
• Bot searches Vast.ai offers and returns a quote
• User approves quote
• Bot generates SSH key, registers it with Vast, creates instance with specified Docker image
• Bot waits for SSH readiness
• Bot uploads inputs, verifies uploads via SHA‑256
• Bot confirms GPU usage with nvidia‑smi and Blender Cycles CUDA check
• Bot runs job over SSH
• Bot downloads outputs, verifies integrity
• Bot destroys instance, deletes SSH key
• Bot confirms instance removal and key deletion

证据

The whole rental, from creating the machine to releasing it, took 194 seconds. Vast posted a $0.007 charge for that instance.

The bot then compared the GPU frame with its earlier CPU preview and told us honestly what had improved and what still fell short, rather than declaring the job done.

The bot uploads its inputs, installs or unpacks the software, and runs the job. Two checks separate a real GPU run from an expensive CPU run: Verify the uploads. Comparing a hash of each file on both ends catches a truncated upload before you pay for a broken run.

The job is only finished when this job's instance ID no longer appears in your instance list and its temporary SSH key is gone.
