I've been using V4 flash consistently with Claude. Pretty great fast and darn cheap. I use it about 3h/day and so far haven't crossed $1 USD/week.

FWIW, I this is what I have in my settings.json

3h/day and how many parallel agents? 1/3/10?

I think out tokens would be a better metric.

[BiraIgnacio]

Max 2 parallel agents, usually.

As for out tokens, it's about 200k/day

Why not use higher thinking effort?

[BiraIgnacio]

Just cause that level seems to be working fine for me and it's usually faster.

Hi, is it comparable to Opus?

[chewz]

V4 Pro is between Sonnet and Opus. But it is cheap. Slow but very cheap. Very diligent.

I run a proxy that allows me switching back to Opus when necessary.

Deepseek isn't like Z.ai which is bit cheaper only on the surface. Or like Qwen 3.7 Max which is Opus-level but very expensive.

Deepseek is my favorite since V3 but V4 is definitely catch-up to newer Anthropic models
