I would be interested in "productive" in this sense, demonstrating a gain vs your overall API spend.

Exactly. Most folks are trying force openclaw on their workflow which would have been way cheaper and better without it

Can you not use it for free?

The harness (OpenClaw) is free, but you have to run a local model or pay for a remote one. Local models just aren't smart or fast enough for good results in this space yet.

Minimax is $10/month. OpenAI/Claude have $20/month. You likely spend more on coffee these days
