In my experience, Deepseek is my favourite model to use for coding tasks. it is not as smart of an assistant as 4o or Sonnet, but it has outstanding task adhesion, code quality is consistently top notch & it is never lazy. unlike GPT4o or the new Sonnet (yuck) it doesn't try to be too smart for its own good, which actually makes it easier to work with on projects. the main downside is that it has a problem with looping, where it gets some concept or context inside its context and refuses to move on from it. however if you remember the old GPT4 ( pre turbo ) days then this is really not a problem, just start a new chat.
