What you can run on the B300

The NVIDIA B300 is a Blackwell Ultra datacenter GPU with HBM3e memory, up to 288 GB per GPU, and hardware support for FP8 and FP4. The large memory suits the biggest models and long contexts. Rent it here by the hour, paid in crypto, with root access over SSH.

Typical tasks

  • Serving the largest language models with room for long contexts
  • Models that need the most memory per card
  • Full fine-tuning and large training runs
  • FP8 and FP4 inference, where your framework and model support them
  • Batch jobs: embeddings, evaluation, data processing

What fits

A rough inference guide, in billions of parameters: weights only, about 20% left for context; real limits depend on context length and the serving engine. It assumes the weights take up to 80% of the total memory, at 2 bytes per parameter for BF16, 1 byte for FP8 and half a byte for 4-bit. With several cards, the serving engine splits the model across them.
