Qwen3.6 27B for running locally (16GB 4060 Ti) and I do often cheat and use Ollama Cloud to run gpt-oss:120B which is still surprisingly good but I've been trying to use GLM 5.2 lately just to try it out.
The trick is to pit these models against themselves as adversaries to spot hallucinations. That really improves the output.
Over time, though I've found that I've gotten better at using these models. Once you've got some solid .md files for context and you get used to the types of prompts that work best (with these models) I seem to be having less and less trouble over time. As in, I have to make fewer fixes or re-runs.
Note: You have to fix stuff constantly with the big models too. So it's not like any of them are perfect. You have to get used to using them effectively over time or you'll just end up with problems down the line.
