Engineer / developer observations of Gemma4-31B, Qwen3.8-27B, and 6.1-Sol for software engineering work

Models: Gemma4-31B vs Qwen3.8-27B at the same quantization (an Unsloth flavor of Q4).

Proof1 community thread

Key points

  • Today I decided to do a few tests on things that I'd consider analogous to "real" work that I do, trying out some different combinations of models and harnesses.
  • Harnesses: Codex CLI vs OpenCode CLI
  • Types of Work: "Tell me about this code" and "Let's make something new"
  • I thought of an application that's concisely scoped, doesn't rely on a legacy codebase or significant external dependencies, and would probably take me ~1-2 days to hammer out by hand. ~8 paragraphs of prompt covering general concept, user experience in a couple different roles, design constraints and future-proofing needs.
