Configuring OpenClaw with VAST.AI GPU Rental for Unlimited Ollama Prompts

OpenClaw Configuration Challenge with Remote AI
A user on r/openclaw wanted to test OpenClaw but found most AI options in its list were paid versions. The only free option was Ollama, which has limited prompts. Even the paid version of Ollama only offers a vague "50% more calls" without exact numbers.
To work around these limitations, the user discovered VAST.AI, a service that rents GPUs with Linux by the hour at low cost. This setup allowed unlimited prompts with Ollama through OpenClaw, running on remote RTX cards.
Configuration Hurdle
The main problem was OpenClaw's configuration limitations. According to the user, "Openclaw doesn't seem to like if you try to configure another remote ai outside of what it's setup for. It only wants to use the official Ollama website or an offline version installed on your computer."
The only successful method was direct configuration of the config .json file: "The only way I could get it to connect to my vast.ai+ollama setup was to configure the config .json file directly, which took some learning to get setup."
User Question
The user asks: "Is there an easier way to setup a vast ai+Ollama with openclaw? instead of fighting with openclaw to get it configured. Since I'm new to this, did i just miss the proper way to do it?"
