Google TPU 8t and TPU 8i
Two TPUs built for the era of millions of concurrent agents
Google's eighth-gen TPUs split into two chips: TPU 8t for frontier model training and TPU 8i for low-latency inference at agent scale. Built for AI teams running production workloads on Google Cloud.
Google just announced its eighth generation of TPUs, and for the first time they're two separate chips: TPU 8t optimized for training, TPU 8i optimized for inference.
The reason this matters: every previous TPU generation was a single architecture asked to do both jobs. That works until scale exposes the tradeoffs. Training needs maximum compute throughput. Inference at agent scale needs memory bandwidth and low latency. One chip can't optimize for both without compromising on at least one.
What it is: TPU 8t and TPU 8i are Google's eighth-generation custom AI accelerators, purpose-built for training and inference respectively, available on Google Cloud later this year.
What makes them different: The split is the differentiator. TPU 8t scales to 9,600 chips in a single superpod with 121 ExaFlops of compute and near-linear scaling up to a million chips via Google's Virgo Network. TPU 8i connects 1,152 chips in a single pod with 288 GB of high-bandwidth memory per chip, 3x more on-chip SRAM than the previous generation, and a new Boardfly topology that cuts network diameter by over 50%.
80% better performance-per-dollar on inference vs. previous generation
2x better performance-per-watt across both chips vs. Ironwood
Supports JAX, PyTorch, SGLang, vLLM natively; bare metal access available
New Collectives Acceleration Engine reduces on-chip latency up to 5x
Benefits:
Specialization means teams aren't paying training-grade compute costs for inference jobs
1,152-chip inference pods mean concurrent agent workloads that would previously require multiple clusters can run as one logical unit
Near-linear scaling to a million chips removes the ceiling on model parallelism for training runs
97% goodput target on TPU 8t means frontier training runs lose less time to hardware failures and restarts
Who it's for: AI infrastructure engineers and ML platform teams at organizations running frontier model training or large-scale agentic inference on Google Cloud.

Who hunted Google TPU 8t and TPU 8i?
Google TPU 8t and TPU 8i was hunted by Raghav Mehra. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
