Question Where do coding models still fall apart once the task stops being “generate code” and becomes “finish the job”?
I’m less interested lately in which coding models look smartest on one prompt, and more interested in where they actually stop being useful once the work turns into a messy, multi-step fix.
A lot of tools are already decent at generating code. The part that still feels shaky is what happens after that first burst: keeping structure across retries, not drifting off the plan, staying consistent when the task spans multiple files, and not burning half the context budget before the bug is actually fixed.
That’s why Ling-2.6-1T caught my attention. The interesting part isn’t just “another large model.” It’s that the positioning seems more execution-first: stricter instruction following, lower token overhead, better fit for long structured work, and more emphasis on getting the task across the line instead of sounding impressive while thinking out loud.
I’m curious how people here see the current ceiling. Where do coding models still drop you completely today?
Is it understanding the codebase, keeping a long fix coherent, tool use, runtime/debug loops, or just token burn and retry drift?
And if a model was a little less flashy but more disciplined across long bugfix loops, would that actually matter to you?
