Cheaper, efficient inference at scale
Google's custom AI chips, rented through Google Cloud, are recommended for cheap, energy-efficient inference and large-scale clusters. Common caveat: hard to program and behind Nvidia at top performance.
Very high token speed
Model-in-silicon chip praised for very fast, low-power inference; the main caveat is that the model cannot be updated without replacing the chip.
Extremely fast token generation speed
People recommend it for very fast LLM inference from a model etched into silicon. Critics note the chip is locked to one model and updates are limited.

How we rank
Rank is the number of separate people who recommend a product in a Hacker News comment over the past year. Someone who praises the same AI accelerator in five threads counts once.
The badge goes to AI accelerators that at least 10 people recommend, with recommenders outnumbering critics at least 2 to 1, recommended in at least 4 of the 13 months.
