Comparing Claude Code vs OpenCode (and testing different models)

Read Original

The article details a hands-on comparison of the Claude Code AI coding assistant and the multi-provider OpenCode tool. The author tests OpenCode configured with different AI models (Anthropic's Sonnet-4, Google's Gemini Pro, and OpenAI's GPT-4.1) on a real-world software development task involving entity updates, migrations, and tests. It evaluates the correctness, reliability, and workflow integration of each model, noting Claude's overall superiority and specific issues with other models.
