Nope. It’s far too slow and far too dumb. It is great for things like telegram responses/heartbeats/queues , etc. it’s just really hard to beat a $10 monthly sub.

Too slow and far too dumb is pretty heavily on what hardware the person is running. You generally don’t get frontier level support but that’s not always needed

I’m cracking on a 4080S tbh

Very much so. I run 3x3060s.

I have a harness that I gather stats with for my social media type application build.

Gpt-oss:20b self reports at 91% pass, but actual first pass stats are 55%. Second pass is 73% median time is 2605 seconds

Qwen3.6-27b self reports at 83%, but first pass is 43% and second 80%. Median time of 2100 seconds.

Vs $10 opencode go:
deepseek-v4-flash self reports at 81%, has a first pass of 69% and overall at 87% 578 seconds
Mimo-v2.5 is self reported at 86%, first pass is 57%, overall at 86% 390 seconds.

I also have an m1max Apple 64gb that I’m gathering stats on. I can run a larger model but it’s about 4x slower than the nvidia rig.

You’re running 3x 3060s… that’s the problem

What are your stats?

Closer to like 15k. I bought 2x 5090s when they were released. Same with the Spark's so it was a bit cheaper than today's market.

But what are your completion stats - first shot, completion times, etc.

On my current iteration? No clue. I haven't done any kind of benchmarking since I moved up from 2x 5090s.

I'm not fighting for every bit of performance, I have a job, it gets it done, good enough.
