🚨 GPT-6.1 SOL — MY TAKE SO FAR .
Overall
Very capable for the price
Handles most everyday coding tasks without much trouble
Has the core strengths of Astra, but still feels like a step below it
3D Work
Can produce solid 3D results
Usually takes 2–3 iterations to get there
Opus 5.5 is noticeably stronger here, with Sonnet 5.5 also feeling more consistent
The Biggest Problem: Speed 💀
I’m seeing roughly 20–30 tokens/sec
Opus 5.5 can push 100+ TPS
That gap makes Sol feel much slower than it should
Best Codex Workflow
Use Astra for architecture, schemas, and planning
Hand the actual implementation over to 6.1 Sol
The combination works extremely well
If OpenAI can seriously improve Sol’s latency, this model could become a much more compelling everyday choice.
🚨 GPT-6.1 SOL:QUICK REVIEW
Solid model for the price and capable across most tasks.
The catch: 3D work often needs multiple passes, and Opus 5.5 still feels stronger there.
The real problem is speed around 20–30 TPS compared with 100+ TPS from Opus 5.5.
For Codex, I’d pair Astra for planning with 6.1 Sol for implementation.
Great model. Just needs to get MUCH faster.
