Compare OpenCode Go vs. Command Code GOAT. Please check the latest official infos and various user opinions on communities and SNS (e.g., Reddit, X). Especially check and summarize the following topics: 1. Pricing 2. Included model usage 3. Usage rate limits 4. Supported models 5. Provide a generous free tier? 6. Privacy (training opt-out and ZDR) 7. Do they allow to use third-party harnesses (e.g., Claude Code, Codex, Pi)? 8. Any other key aspects FYI, I prefer to use DeepSeek V4.1 Flash (1017), GLM-5.3, and GLM-5.3 Flash but if some good proprietary models like Claude, GPT, Gemini it's better.
