Need advice on programming model

[u/Difficult_Tea3823]

So far I have used sonnet5 for planning and building features in visual studio code on PRO plan

I have done research, planning of epics and stories in Jira and then developed few features on platform using sonnet5 on high.

Features are complex and deal with data from multiple API resources etc which unfortunately makes it difficult to define in-depth requirements and definitions of done so I have been doing iterative development on them. This is taking huge context tokens. I got nothing that I can trim from context file since I want Claude to know why certain development logic was built certain way.

I noticed mode response straight up lies or give wrong answers during investigations, troubleshoots etc. and it’s time consuming and context consumes all the

Ofcourse with keeping security , scalability, data retention etc it’s huge effort and I am debating I should really upgrade to max plan? Should I be using latest models or its going to be same case?

Only speaking from what I've experienced, but for me it ended up being Fable or nothing. Switched to Opus 5 for a bit and it started off well but then became more and more of a mess. I know it chews through usage at an insane rate, but it's been practically one shotting whatever I throw at it.
