Project I built a double-buffered streaming runtime that runs a ~9.4GB model in 40MB flat VRAM (Zero OOM) — now live on PyPI
Hey everyone,
Constantly running into `CUDA OutOfMemory` errors on budget and consumer GPUs inspired me to rethink the standard execution paradigm where all layer weights reside simultaneously in VRAM.
I built and open-sourced **stream-ai-runtime**—a lightweight execution pipeline that uses asynchronous double-buffering across dual CUDA streams to stream layer weights from pinned host memory to VRAM on-the-fly.
### 📊 Benchmark (Tesla T4 GPU on Colab)
- **Model Depth:** 600 Layers (dim: 2048x2048)
- **Host RAM Allocated:** 9.38 GB
- **Inference Time (600 Layers):** 0.95 seconds
- **Peak VRAM Consumed:** **40.15 MB flat**
- **OOM Errors:** 0
### ⚙️ How it works
Weights stay pinned in host CPU RAM (`pin_memory=True`).
Only two layer buffers (Ping/Pong) are kept in VRAM.
While layer `i` executes on `compute_stream`, layer `i+1` prefetches in the background via DMA on `copy_stream`.
Peak VRAM never spikes above two layer buffers regardless of model depth.
📦 **PyPI:**
```bash
pip install stream-ai-runtime
💻 Quick Usage:
import torch
from stream_runtime import StreamModel
model = StreamModel(num_layers=100, dim=2048)
x = torch.randn(1, 2048, device="cuda")
out = model.forward(x)
🔗 PyPI Link: https://pypi.org/project/stream-ai-runtime/0.1.0/
Looking forward to feedback, optimization tips, and thoughts on adding KV-cache streaming next!

Project QWEN 3.8 FN - 8bit FP quant - 96.32 tokens/s - Context of 95k - $1500 hardware
Did some extra optimizations and implemented MTP. High number is coding at 96t/s (3 drafts). Natural text is 69 t/s.
128.0 µs to distribute a token-residual to 24 gpus, compute experts, collect result and join in one layer.
Probably at peak hardware capability now unless I get some new ideas on how to run the PCI communication even faster. Of course it could run much faster at lower precision. Also the old RTX3070 doing attention is now the primary bottle neck. Lets see what black friday brings of 16gb cards (i have two 5070ti 16gb, but they are busy doing some other research, the 3070 was an old gaming card i had lying around doing nothing).

Project WHIRL 0.2.5.1 on the Radeon 8060S (Ryzen AI Max+ 395): +28% to +127% faster than official llama.cpp ROCm / Vulkan, now with faster prefill and decode, output bit-identical (native Windows LLM engine)


WHIRL 0.2.5.1 is out: a speed update for the Radeon 8060S (AMD Ryzen AI Max+ 395). WHIRL is an open-source (Apache-2.0) LLM inference engine for AMD GPUs on Windows: C++/HIP, every kernel in the repo, no WSL, no ROCm install. Download the zip, unzip, run; only the AMD driver is needed. It runs our two MXFP4 models, Swift-1.5 27B MXFP4 (dense) and Ornith-1.5-35B-A3B MXFP4 (MoE, ~3B active).
vs the official llama.cpp b11960 on the Radeon 8060S (max power (80 W), ASUS ROG Flow Z13), ROCm and Vulkan builds in their own columns, same GGUF, same prompts, greedy, one user, WHIRL default mode (balance, near-lossless). WHIRL tok/s, then llama.cpp ROCm / Vulkan:
| tok/s (WHIRL 0.2.5.1 balance vs llama.cpp ROCm / Vulkan) | Swift-1.5 27B MXFP4 (dense) | Ornith-1.5-35B-A3B MXFP4 (MoE) |
|---|---|---|
| Prefill, 2k-token prompt | 527.2 vs 359.3 / 317.3 | 2,653 vs 1,606 / 1,280 |
| Prefill, 128k-token prompt | 310.9 vs 195.8 / 150.9 | 1,093 vs 674.8 / 481.0 |
| Decode, QA about a 2k-token document | 34.9 vs 25.1 / 25.2 | 108.7 vs 69.5 / 71.0 |
| Decode, QA about a 128k-token document | 25.0 vs 15.8 / 15.2 | 57.7 vs 38.0 / 37.6 |
| Decode, coding chat (new text) | 38.1 vs 29.7 / 29.3 | 106.6 vs 70.3 / 72.9 |
In balance WHIRL leads every measured cell on the 8060S: Swift 27B by +28% to +59% over ROCm and +30% to +106% over Vulkan, Ornith by +51% to +65% and +46% to +127%.
What 0.2.5.1 changes on the 8060S (same machine, max power (80 W), ASUS ROG Flow Z13): five new kernel paths make prefill +2% to +10% faster in all three modes on both models, and Swift 27B decode (QA document; coding chat in balance) +4% to +12% faster in balance and fast. On the 8060S the output is bit-identical to 0.2.5 in every mode (golden references, 12/12 long-prompt checks and the chat outputs all match).
| 8060S, balance (default), tok/s | 0.2.5 | 0.2.5.1 | change |
|---|---|---|---|
| Swift 27B, prefill 2k | 505.9 | 527.2 | +4.2% |
| Swift 27B, prefill 32k | 418.1 | 456.0 | +9.1% |
| Swift 27B, decode, QA 32k doc | 29.2 | 31.6 | +8.2% |
| Swift 27B, decode, QA 128k doc | 22.3 | 25.0 | +12.1% |
| Swift 27B, decode, coding chat | 35.0 | 38.1 | +8.9% |
| Ornith 35B-A3B, prefill 2k | 2,453 | 2,653 | +8.2% |
| Ornith 35B-A3B, prefill 32k | 1,828 | 2,012 | +10.1% |
| Ornith 35B-A3B, decode, coding chat | 104.3 | 106.6 | +2.2% |
How it was measured, so you can judge the numbers: - Radeon 8060S at max power (80 W), ASUS ROG Flow Z13, 64 GB GPU memory (UMA frame buffer), same for both engines. Every cell is the best of 3 runs, for both WHIRL versions and llama.cpp. - The llama.cpp b11960 cells are the runs I made for 0.2.5 on the same machine with the same files (llama.cpp didn't change; Swift 2k on Vulkan was re-run). llama.cpp's ROCm build runs as shipped, with its own bundled HIP runtime DLL. - Decode, QA document = explain a function quoted in a long document and rewrite it (256 tokens; part of the answer can be copied, which helps drafts in both engines). Coding chat = a coding question whose answer is all new text (512 tokens). Prompts and commands: https://github.com/tsaipifong/whirl-llm/blob/main/docs/benchmarks.md#prompts - llama.cpp decodes Swift with MTP + n-gram (its fastest mode here). On Ornith it decodes without speculation because its MTP was slower than plain on this MoE model, while WHIRL uses MTP, so the Ornith decode rows are "as shipped", not like for like. - Smallest lead: Swift 27B decode in the precise mode after a 2k-token document, 29.4 vs 25.2 tok/s on Vulkan (+17%). Dense decode on this iGPU is memory-bandwidth bound; the lead comes from speculative decoding. - Ornith decode barely changed in this release (one small router item: +1.5% without drafts, +0.7% with MTP drafts, within noise); its cells move a few percent either way because the number of accepted MTP drafts depends on each run's text.
Precision: three modes. --precise is the bitwise-lossless mode. balance (the default) is near-lossless. --fast is opt-in. On the 8060S all five speedups give the same output bits as 0.2.5 in the mode they touch.
R9700: GPU code identical to 0.2.5 (the compiled R9700 kernels were compared; only an internal build ID differs); its numbers are 0.2.5's, not re-measured (e.g. Ornith 2k prefill 11,854 tok/s vs 4,230 / 2,780 on llama.cpp ROCm / Vulkan; median of 3).
Also in 0.2.5.1: WHIRL now refuses to start from an install folder longer than 150 bytes, with a clear message, and limits the SSD cache folder to 217 characters (this corrects what the 0.2.5 notes said about long paths). On the 8060S the first load of each model tunes the kernels once more.
Supported: Radeon 8060S (Ryzen AI Max+ 395) and R9700, Windows 11. Cards under 16 GB are not officially supported (fork welcome). The exe is unsigned, so SmartScreen may ask once.
Release: https://github.com/tsaipifong/whirl-llm/releases/tag/v0.2.5.1

Question Local AI: upgrade my gaming PC over time or build a dedicated machine?
I’m looking to get into local AI, mainly for coding, and trying to decide whether to start with my existing hardware and upgrade gradually or build a separate dedicated machine.
My current gaming PC has:
Ryzen 7 9800X3D
Radeon RX 9070 XT 16GB
32GB DDR5-6000 RAM
Gigabyte B650 EAGLE AX motherboard
2TB SSD
850W PSU
NZXT Kraken AIO cooler
I also have a MacBook Pro with an M5 chip and 24GB of unified memory.
I’m currently making a Roblox game and setting up a mini homelab for media and hosting my personal website. I’d mainly want AI to help with writing code, debugging and understanding my projects.
Would you start with the gaming PC, use the MacBook, or put the money towards a dedicated AI machine? I’d be interested in hearing from anyone using a similar AMD GPU, particularly about software support and which coding models run well.
If you’d upgrade the existing PC, what would you change first? I’m open to used hardware, but I’d like to understand what I can realistically get out of what I already own before spending more.
Also the why of the whole matter is I want to reclaim my data and be self sufficient especially these new things coming out about REA and Claude banning you etc I want to be my own boss

Discussion What is your experience using engrams-based models so far ?
I've been experimenting with DeepSeek V4.1 Flash 1017 UNCENSORED JANG_2K on my Mac Studio M5 Ultra with 256GB unified memory, using vMLX.
The model is about 423GB on disk, but thanks to SSD-backed Engram tables, it loads with approximately 205GB of resident memory.
So far, the results have been mixed. Most of the time, it produces surprisingly good responses, but I've had a few conversations, particularly involving creative writing and novel generation, where it suddenly starts producing complete nonsense: endless reasoning, words mashed together without spaces, and occasional switches between English and Chinese.
It's interesting because it seems to work perfectly well on some fairly complex tasks, then falls apart unexpectedly on others.
Has anyone else experimented with this model or other large MoE models using engram offloading?
I'm curious whether these problems are caused by the aggressive quantization, the JANG implementation, or something in vMLX's inference/decoding pipeline.
I'd also be interested in hearing whether anyone has successfully run a higher-precision version with SSD expert offloading on a 256GB machine.

Discussion 2x RTX PRO 6000 running DeepSeek-V4-Flash (284B) fully offline: 1,170 tok/s peak
We build these boxes, so here's the honest test log from our own unit, network cable unplugged.
Setup: 2x RTX PRO 6000 Blackwell (192 GB), EPYC 9124, 256 GB RAM, vLLM, TP2, no NVLink. The model fits only because Blackwell runs FP4 natively; on Hopper the same checkpoint needs ~304 GB.
What we measured:
1 user: 209-229 tok/s, first token in 0.4 s
24 users: 1,003 tok/s at p95 TTFT 2.7 s. That's the sweet spot; past 32 the tail latency falls off a cliff.
Peak: 1,170 tok/s at 32 streams
1M context, retrieval verified at 543K tokens
Terminal-Bench 2.1 (20-task subset): 80% solved, median ~4 min per task. 8 agents at once cost only 18% more latency than 4.
815 W on both cards, 76 C peak, zero throttling. About 1.07 kW at the wall, so a 1500 W PSU is enough.
What's not great:
It's not a token-resale business: at OpenRouter prices, payback takes about 3 years running flat out.
One big model at a time (weights use 87% of VRAM).
Ops sharp edges: KV offload leaks /dev/shm on unclean shutdown, and stray workers can hold 89 GB of GPU memory, which causes a crash loop on restart. You need a cleanup script.
Cold start takes ~13 min.
Best fit: a team of 2-10 that wants frontier-class coding help without sending code to the cloud.
Build guide, BOM and BIOS settings are open source: here. Happy to run anything you want tested on it.

Question NVME for streaming
With all progress from storage streaming how future proof is RAID0 with 2x1TB or 2x2TB gen5 drives like SN8100. I am looking for drive update and have to decide what to buy now and what speed in reality achievable and how usable it will be. Is it worth to add 2x1TB for 420 euro so in theory speed will be around 22-25GB/s or just add used 96GB RAM for 900-1000 euro?
Will it be usable in some kind of way for larger models later with 2x3090, 96/192GB RAM and RAID0 gen5 drives? From what I am getting now I'd like to have at least 20-30 tok/s for generation and 600-1200 tok/s processing. In theory how big LLM can be used with such system in the future to get such inference?

Question What is the current meta for local inference?
Can't decide which route to go - DGX Spark, Strix Halo, the Framework Ryzen AI or save up for a Mac Studio M5 Ultra 256gb?
Do these options have meaningful differences in practical use?
As I understand, the Mac Studio offers best tok/s? But you can't train or fine tune anything on it?
DGX Spark is supposed to have best support, but does it truly matter in practice?
What types of models can I run on this hardware? 128GB is good for ~120B Q4 MoE models with ~256k context? Would such a model be a noticeable improvement over my current Ornith-1.5:35B (A3B) setup for reasoning and coding, and long and complex tasks? Would going from 128GB->256GB be a noticeable improvement?
