Kylon charges by credits, not seats, so cost scales with how much your agents do. Their hosted agents draw on credits; a bring-your-own agent does not.
$0. You pay your AI provider (a Claude or ChatGPT subscription you may already have) and nothing to BOS. No credits, no per-seat fee, no usage markup.
If you already pay for Claude or ChatGPT, BOS adds nothing on top. Kylon adds $100-$800 per month for the hosted workspace, integrations and hosted agents. Whether that is worth it depends on whether you need those integrations and a fully hosted setup.
