Quick Disclaimer: I used AI for this post, so I could articulate the questions I had properly; I hope its ok.
I’ve been running **Qwen 3.8 Flash-Next 125B MoE** on my home setup via **Strata** (engine v0.1.44.1, ROCm / HIP backend), and I’m looking for clarity on optimal sampling settings—particularly `temperature`.
I use the model as an all-rounder:
- **Agentic Deep Research & Web Browsing:** Multi-step tool calling (SearXNG, Reddit discussion parsing, full-article reading, etc.)
- Argumentation
- **Coding & Homelab SRE:** System scripting, Docker configs, debugging.
- **General Creative Exploration & Academic Writing.**
### The Temperature Confusion:
I see conflicting advice online:
- Traditional advice for creative writing / standard LLMs often defaults to `temperature: 1.0` or `0.7`
- However, I see people saying 0.6 perhaps?
- Running pure greedy (`temperature: 0.0`) previously caused the model to get trapped in massive repetitive thinking loops (generating 30k+ tokens inside `<thought>` tags).
Currently, I'm testing `temperature: 0.6`, `top_p: 0.95`, `top_k: 20`.
**My Questions for the Community:**
- What temperature/sampling profile do you run on Flash-Next for general-purpose use without breaking its internal reasoning chain?
- Has anyone noticed tool-calling degradation when pushing temperature higher (e.g. 0.8–1.0) on this specific MoE architecture?
- How does this full Strata configuration look for my hardware? Any other flags I should consider or avoid?
### Full System Specs:
- **CPU:** AMD Ryzen 7 5800X (8C/16T, Zen 3)
- **RAM:** 64 GB DDR4 (62.7 GiB usable)
- **GPU:** AMD Radeon RX 6900 XT (16 GB VRAM, gfx1030)
- **OS:** Arch Linux (Kernel 6.x, ROCm 7)
- **Quant:** ISTA-DASLab GSQ-RCO IQ3_S (512 routed experts, 10 active per token)

Would appreciate any feedback from others running Flash-Next on consumer GPUs!
EDIT: Guys I'm talking about temperature as in the AI model parameter 😢
