Ahmad@TheAhmadOsman
I like your stuff so far, keep going
Sudo su@sudoingX
this guy just cracked 134 tok/s on qwen 3.5-27b dense and 73 on new qwen 3.6-27b on a single 3090. open source moves at godspeed in 2026.
Lotto@LottoLabs
Interesting run w/ Dflash from the lucebox-hub guys
Rijndael@rot13maxi
speculative PREFILL?????
Riku Pasonen@Raitziger
I have tested some LLM server software for home PCs for Linux and Windows. Fastest and best for running home is Linux running 145 t/s, Lucebox. @pupposandro @luceboxai
fahd Mirza@fahdmirza
PFlash just killed the 4-minute blank screen problem. 128K token prefill in 25 seconds, same GPU, same model, no compromises
Geek Lite@QingQ77
Consumer-grade GPUs actually have sufficient hardware potential, general-purpose frameworks just waste most of it on overhead. Lucebox releases that potential through hand-written kernels, letting even a 2020 RTX 3090 rival Apple's latest chips on efficiency.
Takyon∞@Takyon
Crazy I was litteraly wondering how can I increase my token speed 10 min ago
Kyz2ren@ky2renzz
Crazy what @pupposandro just dropped on Qwen3.5-27B. 207 tok/s on a single 3090 with Q4_K_M and full DFlash speculative? Chinese labs + ggml hacks are just cooking on consumer hardware right now. This is the kind of local win I like to see.
Ivan Fioravanti@ivanfioravanti
RTX 3090 ready for a new life! Bringing it to @luceboxai team to make some experiments together
vitalik.eth@VitalikButerin
github.com/Luce-Org/lucebox-hub looks promising as a way to run "dense" models (eg. Qwen 27B) more efficiently. It's janky, but on my 5090 laptop it seems to be ~2x more tok/s than llama.cpp
CAPET@Capetlevrai
This is very very good work BRAVO. I love it
nash_su@nash_su
Nearly 10x faster! After finishing Decoding, it starts cranking through Prefill. The previous DFlash was already stunning enough, and now they've added PFlash. Speculative prefill, up to 10x speedup. Go try it right now.
AJ@ItsmeAjayKV
First time reading about speculative prefill, and it's crazy. 257s down to 24s for a 128K prompt on a single RTX 3090. Great article, definitely go ahead and give this a read.
Twon.@Web3Twon
impressive... so this is what it looks like when you focus on a set ram limit and optimizing for a single model above everything

DFlash
207 tok/s peak / 130 sustained
Speculative decoding on ggml for Qwen3.5-27B Q4_K_M, with the published setup and results.
PFlash
24.8s TTFT at 128K
Speculative prefill cuts a 128K prompt from about 257 seconds to 24.8 seconds on the published CUDA reference run.
Luce Spark
35B MoE / 13.3 GiB
Only the experts used by the current tokens stay resident, so larger MoE models fit on smaller GPUs.
KVFlash
2.9× decode at 256K / 38.6 tok/s
Runs 256K context on a 24 GB card while reducing KV VRAM from 4.6 GiB to 72 MiB through bit-exact paging to host memory.

Frequently Asked Questions
A plug-and-play computer for local AI inference. It arrives with our open source inference engine, tuned models, custom kernels, and speculative decoding ready to use through a single CLI.
An AMD Ryzen AI MAX+ 395 with 128GB of LPDDR5X-8000 unified memory, an AMD Radeon AI PRO R9700 with 32GB of GDDR6, a 2TB KingSpec XG7000 NVMe SSD, and a Corsair SF1000 1000W 80+ Platinum power supply. The custom aluminium chassis has a volume of 11.97 liters.
$6,499 USD per machine through August 31, 2026, then $7,900. Global shipping is included. After a short call confirms fit and availability, we send a secure purchase link.
Production units ship in limited batches. Demand currently exceeds capacity, so delivery windows can vary. We confirm expected timing on a call before sending a purchase link.
Yes. Include the quantity in your application. We review larger requests based on the use case, destination, and current production capacity, so allocation and delivery timing are confirmed on the call.
Yes. Our inference work is public at github.com/Luce-Org/lucebox-hub, with 50+ contributors, 500+ pull requests, and more than 10 released versions. It includes hand-tuned kernels, DFlash speculative decoding, PFlash prefill, and hybrid-model optimizations.
Far more than fits in 32GB of VRAM. The Strix Halo's 128GB of unified memory lets you run much larger models too, like MiniMax 2.7 and DeepSeek V4-Flash. We pre-tune Qwen3.6, GLM-4.6, DeepSeek V4-Flash, and the Llama 4 family, and you can bring your own GGUF, the CLI takes care of loading it.
Yes. Lucebox exposes OpenAI-compatible and Anthropic-compatible endpoints. Point a supported client or agent harness to the Lucebox base URL and keep using its normal workflow.
Lucebox does not require either one. It exposes an OpenAI-compatible endpoint, so tools that accept a custom base URL can connect directly while Ollama and LM Studio remain available for any separate workflows you already use.
No. Lucebox runs fully offline once your model is loaded. Internet is only needed for updates and the optional cloud fallback.
The system is quiet at idle and the Radeon AI PRO R9700 cooling system becomes audible during sustained inference. The chassis directs hot air out the back, away from the desk area.
Around 500 watts under full inference load, with up to 300 W for the Radeon AI PRO R9700 and the remaining system power allocated to the Ryzen platform and components. Idle consumption is approximately 40 W. Plug it into any standard wall outlet.
One year on the full machine, parts and labor. We replace or repair any unit that fails under normal use.
Yes. Full root access. It is your machine. Open the shell, install whatever you want, run whatever you want.
If a unit arrives damaged, is dead on arrival, or develops a fault covered by the warranty, contact us and we will arrange the appropriate repair, replacement, or refund. Full terms are provided before purchase.
Yes. Global shipping is included in the listed machine price. VAT, duties, and import taxes remain separate where applicable. We confirm the destination and expected delivery window on the call.
Yes. The 128 GB of unified memory plus 32 GB of VRAM lets you keep a hot model resident in VRAM while a second sits in unified memory ready to swap in. The CLI handles loading and routing per request.
