the TT-QuietBox Blackhole comes with

> ~80 lbs liquid-cooled chassis
> AMD EPYC 8124P, 16c/32t
> 512 GB DDR5 ECC
> 4 TB NVMe
> ASRock Rack SIENAD8‑2L2T w/ 2x 10 GbE + IPMI

> 4x Blackhole p150c cards, totalling:
> 560 Tensix Cores
> 64 “big” RISC-V cores
> 128 GB GDDR6
> 840 MB On‑Chip SRAM
> 3.2 Tb/s Ethernet mesh
> 16x QSFP‑DD 800G ports for card⇔card comms
> 8x passive direct‑attach copper (DAC) cables (0.6m)

> all of this is powered by a single
> 1650W Platinum PSU, passively cooled
> ready to daisy-chain to the next QuietBox
> also, opensource stack (TT‑Forge → TT‑NN → TT‑Metalium)

the interconnect is the star

> what does “4x QSFP‑DD 800G” actually mean?

> QSFP‑DD = Quad Small Form‑Factor Pluggable — Double Density
> 8 electrical lanes per port
> ~100 GB/s per lane using PAM4 signalling
> total: 800 Gb/s full‑duplex per port → ~100 GB/s usable each way after Ethernet framing + FEC

each card talks directly to its siblings over QSFP‑DD 800G

> 4 ports per card x 800 Gb/s each =
> 3.2 Tb/s of aggregate bidirectional fabric per card

> 16 ports total per “quietbox” =
> 3.2 Tb/s internal mesh across all 4 cards

> this is your NVLink replacement
> no PCIe bottlenecks, no host-side relays
> just a true east-west ethernet fabric

there’s a hard rule
> the QSFP‑DD 800G ports are passive
> they only connect to other Blackhole cards via direct‑attach copper (DAC)
> max length = 2 meters, not optics, not switches, not uplinks to your ethernet fabric
> Blackhole fabric is its own world: card⇔card, box⇔box, nothing else

daisy‑chain the DACs and you’re all set, add more boxes and enjoy the 3.2 Tb/s ethernet mesh that pools memory and scales almost linearly

pretty sleek hardware UX, more soon

RT @TheAhmadOsman: i built a simple tool that makes

Claude Code work with any local LLM

full demo:
> vLLM serving GLM-4.5 Air on 4x RTX 3090s
> Claude Code generating code + docs via my proxy
> 1 Python file + .env handles all requests
> nvtop showing live GPU load
> how it all works

RT @TheAhmadOsman: who here would like to see a build video guide for multiple RTX PRO 6000s?

already got the hardware ordered for a couple of 3090s and 5090s build guides btw

yes, there'll be GPU giveaways ;)

first video guide before Thanksgiving

anyway, Buy a GPU keeps on winning

@TheAhmadOsman Probably nothing 👀🔥 https://t.co/sCr29jVV7J - Mike Bradley

top 5 local LLMs to run at home in October 2025

> GLM-4.5-Air at #1
> daily driver & all-around MVP
> budget legend, agentic and coding, fits on 4x 3090s
> nearly as good as big brother, however, not as power hungry

> GPT-OSS-120B at #2
> feels like a GPT-5 at home
> big brain, smart and consistent
> agentic, coding, but feels dry in writing

> GPT-OSS-20B at #3
> absolute speed monster
> holds up well at tool calling (short context preferred)
> pretty good at instruction following, quick bug fixes, and general use

> Qwen3-30B-A3B at #4
> best for trivia and knowledge dumps
> not as fast as GPT-OSS-20B, but way more book smart

> Qwen3-Coder-30B at #5
> very capable at coding
> will run on 16GB VRAM quantized

> GLM-4.6 honorable mention
> the local king if you’ve got 4x Pro 6000 Max-Qs
> “beast mode” for tool use, workflows, and bug fixing
