Runtime profiles and requirements

The catalog profile uses an Ollama tag. Its configured context and unspecified download precision are not a claim about the upstream checkpoint's maximum context or a fixed weight revision.

Deployed artifact revision: Not verified

Catalog thresholds are configuration guidance, not measured peak memory. A positive GPU requirement is not recorded for every profile; unspecified is not zero. Context, concurrency and runtime overhead can increase memory use. Configured context is a profile setting, not the upstream maximum. Concurrency is configuration, not a load-test result.

Weight-only arithmetic and a planning estimate

Using the catalog's approximate 8B total parameters, 16-bit weights alone occupy about 16 GB (parameters × 2 bytes). The shared sizing helper rounds a 20% planning reserve to 19 GB.

This arithmetic does not describe the selected quantized artifact. It excludes a workload-specific KV-cache calculation and cannot guarantee fit at the configured context or concurrency. A mixture-of-experts model still stores its full weights.

Plan the machine.

Memory-based machine candidates depend on the current visible store configurations. Confirm runtime compatibility, GPU count, interconnect and workload before purchase. Pricing and availability are shown on the machine page.

Before deployment

Test the workload you need.

Test answer quality on your documents before increasing model size. Keep retrieval, prompt format and output limits fixed when comparing it with Llama 3.3 70B.

These are catalog profiles and planning figures. No B3IQ performance measurement or live capacity is claimed. Confirm the artifact, runtime, workload and machine before deployment.
