Intel Habana Gaudi (first-generation) AI training accelerator
Intel's first-generation Habana Gaudi is a PCIe AI training accelerator launched in 2019 by Habana Labs (acquired by Intel in 2019). It powers AWS EC2 DL1 instances and on-prem AI training boxes, and was the precursor to Gaudi 2 and Gaudi 3.
recommendation
Worth keeping but flagging as legacy hardware. Although Intel now markets Gaudi 2 and Gaudi 3 as the lead products, the original Gaudi is still listed on Intel's site, still backs AWS DL1 cloud instances, and habanalabs upstream maintenance actually resumed for Linux 6.18 in late 2025 (per Phoronix), so removal would be premature. Annotating it as a low-volume, first-generation accelerator helps set expectations for anyone evaluating the code today.

sources
- intel.com
Intel still maintained a dedicated product page for the first-generation Intel Gaudi AI accelerator, describing cloud and on-prem options and stating Gaudi software supports first-gen Gaudi.
- aws.amazon.com
AWS still listed DL1 instances powered by Gaudi accelerators, indicating ongoing deployability and availability in current cloud offerings.
- intel.com
Intel's current Gaudi product-family page centers Gaudi 3 and compares against Gaudi 2, implying first-generation Gaudi is no longer the lead product for new deployments.
- phoronix.com
Reported renewed upstream habanalabs activity for Linux 6.18 in late 2025 rather than removal, consistent with continued maintenance.
- codebrowser.dev
The Gaudi directory is still present in a recent upstream Linux source snapshot, showing the support code remains in-tree.
codex reasoning notes (technical)
Local `exec_command` inspection showed this is real ASIC-specific kernel driver code under the habanalabs accelerator, with firmware declarations in gaudi.c and recent local git history continuing through 2025-09-25; no local sign of retirement. URLs were obtained via `web.search_query` results: Intel gaudi1 page for product/support status, AWS DL1 page for present-day deployment evidence, Intel Gaudi family page for lineup positioning, Phoronix for the 2025 upstream-maintenance resumption report, and Codebrowser for current in-tree presence. Taken together, Gaudi1 looks older and likely niche for new buys, but still deployable and still maintained enough that deprecation/removal would be premature; annotate as legacy/low-volume instead.
