DeepSeek v4 Pro should be taken seriously
For the last 2 days, I have been using the DeepSeek v4 Pro model via OpenCode Go and it has been a fantastic experience. I never expected the model to be this good at UI as well as logic.
For example, I am creating a custom blog publishing CMS powered entirely by Cloudflare (D1, R2, and Workers). Initially, I used Codex for this and Codex did get the first working version ready, but the UI was very bad and cluttered and the user-experience wasn't great either. I didn't even like the CMS a bit.
But then I fired up OpenCode and gave everything to the DeepSeek v4 Pro model, and asked it to re-do and re-design everything by keeping user-experience in mind. I, then, went to the gym and the model had done its magic by the time I returned. It ran for ~35 mins and completed everything in one go, and the design was already looking much cleaner and just better.
I still had to give a few more prompts to refine some things, and it did everything perfectly. Just for your information, while working, I kept the thinking effort as default, as you see in the screenshot.
From the next month, I think I am going to save a decent amount of money on AI tools subscriptions. Currently, I am subscribed to Codex $100 plan but now I think Codex $20 with OpenCode $10 (+ $10-20 for extra usage) should be enough for my use case.
Lastly, I think the DeepSeek v4 models should be taken more seriously by everyone. Their API pricing is also currently discounted by 75%, and there is absolutely no reason to not use this model.
