Bottom line first: if you use Claude Code / Codex for everyday coding, you should no longer treat “#1 on SWE-bench” as the only yardstick for choosing your main model. In 2026, the more reliable public stack is Terminal-Bench + SWE-rebench/DeepSWE + a cost dashboard; the final verdict still has to come from tasks in your own repositories. What you’re evaluating is not “can it write a function,” but “can it act like an engineer over time” If your workflow looks like this:

Coding Agent Candidate Scorecard: Grok 4.6 / Qwen3.8-Max / DeepSeek-V4 Pro / GLM-5.2

TL;DR: This is the targeted follow-up to “How to pick your daily Coding Agent model — stop worshipping SWE-bench #1” — we put four candidates (grok-4.6, qwen3.8-max, deepseek-v4-pro, glm-5.2) on official leaderboards and pinned down each score. None of the four beats the public frontier (claude-opus-5 74% / gpt-5.6-sol 73% / fable-5 70%); but on “cheap + good enough” there is a clear route: GLM-5.2 for 80% daily work, Grok 4.6 for hard tasks, DeepSeek-V4 Pro as the cheap sub-agent.
