Sonnet on Cowork for Vibe Coding?

Anyone else coding complex apps using Sonnet on Cowork?

I've achieved a fair bit in little time over the last month or so, but am becoming increasingly frustrated by hitting session, weekly and monthly limits on the Pro plan, and keep having to buy credits...

I've built a autonomous software engineering pipeline on Opencode, firstly using LLMs on Ollama, but then using Deepseek V4 Flash on Opencode Go. Kept encountering bugs on Opencode Go with Ollama.

Just wondering what other people's experiences are, particularly around cost. I'm no coder (just a Linux/Bash guy) but have found AI to be useful, though a little frustrating at times.

Need to move away from Anthropic.
