The main thing I always get away from the comparison tables of these "big" models, is how well Deepseek v4.1 Flash performs. While still being the cheapest model by a long shot.
Will say their research is some of the best reads in the industry and I could not care less about their model release cadence as long as papers keep coming.
Maybe it is due to us being all very experienced devs. And can steer the model. But my daily routine is just to have 8-9 Zellij tabs open, DeepSeek in omp in each, and grind research and code day and night. Really nice model...
With structured tool calls you do want to be lenient on parsing, but that is a very small price to pay when the model is 100x cheaper.
It is great on creating summaries and content.
