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: working on getting nanochat training running with TT‑NN

the more i push my single Tenstorrent QuietBox Blackhole,

the more i see just how much headroom this thing has

counting down until my 4x TT‑QuietBox Blackhole cluster arrives

this cluster's going to be an absolute beast https://t.co/lN9VsITgDs

RT @TheAhmadOsman: the Tenstorrent QuietBox Blackhole

> is a 3.2 Tb/s Ethernet mesh

> and scales almost linearly
> when you daisy‑chain more boxes

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: My house has 33 GPUs.

> 21x RTX 3090s
> 4x RTX 4090s
> 4x RTX 5090s
> 4x Tenstorrent Blackhole p150a

Before AGI arrives:

Acquire GPUs.

Go into debt if you must.

But whatever you do, secure the GPUs. https://t.co/8U89OStknt

RT @TheAhmadOsman: can’t write code because Cursor and Codex are both down thanks to the aws-us-east-1 outage?

tired of Anthropic’s weekly limits and nerfed models?

with one command and a few GPUs,
you can route Claude Code to your own local LLM with ZERO downtime
