# GPT-5.6 in Hermes Agent: Setup, Reasoning Level & 3 Use Cases

Alex Finn switches his Hermes Agent default from Claude Opus to GPT-5.6 "Soul," calling it smarter, dramatically cheaper (a flat subscription instead of the roughly $200/day he was spending on the Opus API), and better at agentic computer use. He walks through setting the model in the Hermes dashboard, why he runs reasoning at **medium**, and three use cases: a home AI lab, an autonomous Unity game studio, and website price-drop monitoring.

## Key Takeaways

- **Set the model in the dashboard.** Run `hermes dashboard`, open *Models*, change the main model, type `Codex`, and choose *OpenAI Codex* to select GPT-5.6 Soul. Soul is the top tier of the 5.6 family, above Terra and Luna.
- **Tune reasoning to medium.** In Telegram, send `/reasoning medium`. Alex tested every level and found medium the sweet spot; low is a solid second choice for speed. High/extra-high/ultra overthink, burn tokens, and drop instructions. On the $20/month plan he suggests low.
- **Cost and capability.** GPT-5.6 in a subscription replaces the hundreds of dollars a day he was spending on the Opus API, while giving better computer use — controlling the browser, taking screenshots, and running local models.
- **Use case 1 — home AI lab.** Prompt Hermes to read your machine's specs, browse Hugging Face for the best local model it can run, and list use cases — then build a control panel to monitor and chat with the models running on each of your computers.
- **Use case 2 — autonomous game studio.** He has Hermes drive Unity end-to-end — generating assets, characters, environments, and lighting for playable 3D games — and rates Unity the engine agents handle most completely.
- **Use case 3 — price-drop monitoring.** A Hermes cron job checks a site daily (his example: Micro Center for RTX 5090 stock and price drops) and texts him on a change — a handy pattern for scarce hardware.
- **Honest caveat:** he still finds Claude more decisive with a stronger "personality"; GPT-5.6 tends to agree and change its mind when challenged. He also frames Hermes-vs-OpenClaw as a reliability preference, not a benchmark result.
