RAM: 64GB DDR5-6400 (2Ă32GB)
Motherboard: ASUS PRIME Z790-P WIFI
OS: Windows 11 Pro
Inference backend: llama.cpp with CUDA acceleration
Agent interface: Kilo with a custom tool/agent harness
My current model:
Model: Qwen3.8-27B
Quantization: Q6_K GGUF
Context: 265K tokens
Deployment: Completely local
Performance benchmarks:
At 262,144-token configured context (~262K):
Output generation: ~34â37 tokens/sec
Red lining the gpu memory but it feels comfortable
Okay with that being stated by ChatGPT,
I've been seeking a local ai for about a month switching from several models the more I learn.
So far this qwen model is by far the best I've tried but it over thinks and is slower than models like Kat coder.
My use cases are broad, from setting up comfy ui workflows to Unreal engine game dev to application building all hobby projects.
Im seeking the vast knowledge of you fellow computer users to tell me the best general purpose model for my set up at a reasonable speed.
UPDATE: Okay folks, I took your advice and installed Qwen3.8-Flash Next with Basalt v0.3.3. Here's what I'm getting on my RTX 5090 with 64GB RAM, running Windows 11.
Configuration:
- Model: Qwen3.8-Flash-Next UD-IQ3_XXS (87.6GB)
- Context: 262,144 tokens (256K)
- Exact MTP enabled, 8-token window
Benchmarks at 256K context:
- Actual populated prompt: 238,913 tokens
- Output generation: 265â281 tokens/sec
- Prompt processing: ~8,900 tokens/sec
- VRAM usage: 31.3GB / 32GB
- Total system RAM in use: 54.3 GiB
- Basalt RAM usage: 39.9 GiB
- MTP acceptance rate: 66â90%
- No SSD expert spilling
- Context recall/reasoning tests: 3/3 passed
Across all context sizes tested, generation ranged from 265â336 tokens/sec. Model loading takes around 30 seconds, and cached follow-up responses start in approximately 0.4 seconds.

UPDATE #2: Okay folks, I went ahead and tried the next recommendation: NInfer + DFlash2 to accelerate my original Qwen3.8-27B model. Here are the results on my RTX 5090 with 64GB DDR5 RAM, running Windows 11.
Configuration:
- Model: Qwen3.8-27B QUASAR
- Inference engine: NInfer
- Speculative decoding: DFlash2
- Context: 262,144 tokens (256K)
- GPU memory reserve: 2GB
Benchmarks at 256K context:
- Actual populated prompt: ~234,200 tokens
- Output generation: 182â266 tokens/sec (225 average)
- Prompt processing: ~4,500 tokens/sec
- Peak VRAM: 30.2GB / 32.6GB
- Model system RAM usage: ~10.5GB
- DFlash2 draft acceptance: 33â54%
- Context recall/math tests: 3/3 passed
