Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.\n\n**Hermes Agent.** Card payments always ask first and are refused in unattended sessions, and the messaging gateway denies every sender until an allowlist is set. Shell commands run on the host by default with a model judging risk, and sending mail through the Google Workspace skill is held back only by an instruction to the model.\n\n## Before you call either\n\n### Gemini Spark\n\n1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription\n2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one\n3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them\n4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached\n5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service\n\n### Hermes Agent\n\n1. Set `approvals.mode: manual` before giving it real accounts. The default `smart` lets an auxiliary model approve commands\n2. Run the gateway with `terminal.backend: docker` or the project's Docker image when it reads mail, web pages or group chats\n3. Set `memory.write_approval: true` and `skills.write_approval: true` to review what it saves about the owner\n4. Leave `approvals.cron_mode` and `approvals.unattended_mode` at `deny` for scheduled and webhook runs\n5. Set `TELEGRAM_ALLOWED_USERS` or the matching allowlist per channel. Never set `GATEWAY_ALLOW_ALL_USERS=true`\n\n## Questions\n\n### Which is better for AI agents, Gemini Spark or Hermes Agent?\n\nHermes Agent scores 67.9 (B) on agent readiness against Gemini Spark's 24.5 (F), and leads in every scored category.\n\n### Are Gemini Spark and Hermes Agent open source?\n\nNo open-source release is listed for Gemini Spark. Hermes Agent is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/gemini-spark-vs-hermes-agent.json, and with the fewest tokens: https://www.anchorterminal.com/compare/gemini-spark-vs-hermes-agent.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"gemini-spark\", \"b\": \"hermes-agent\"}`.
