Reddit r/opencodeCLI: Discussion of Grok 4.6 on DeepSWE and Terminal-Bench

Scores discussed

The comments cite a 65.9% score for Grok 4.6 on DeepSWE v1.1, noting that it is higher than DeepSeek V4 Pro 0813's 62.7%. This indicates a clear improvement over Grok 4.5's 54%, but it remains below GPT-5.6 Sol Max's 73%.

The post also discusses version changes in Terminal-Bench: after the move from 2.1 to 3.0, models that had originally scored close to 90% could fall back to around 30%. Scores from different versions therefore cannot be compared directly.

User feedback

• One user uses Grok 4.6 in Cursor Enterprise and considers it suitable for work involving large numbers of tokens.

• One user considers Grok 4.6's capabilities close to Opus 5's, but says the 500K context window remains limiting for some architect-type work.

• Another group of comments uses Grok 4.6 for simple E2E tasks and sub-Agents, describing it as "smart enough and very fast."

• Some comments argue that DeepSWE reflects only repository tasks and hidden tests, and cannot represent architecture, maintainability, or long-term collaboration in real development.

Conclusion

This post is more of a quick community interpretation of public scores than an independent rerun. Its value lies in reminding readers to consider DeepSWE, the Terminal-Bench version, and the test objective together when assessing Grok 4.6's coding results, and to evaluate "speed suitable for sub-Agents" separately from "stability when completing complex engineering work independently."
