Runtime profiles and requirements

Active parameters do not equal the weights you must store. Plan memory for the full checkpoint and validate long-context behavior on the runtime you choose.

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 30B total parameters, 16-bit weights alone occupy about 60 GB (parameters × 2 bytes). The shared sizing helper rounds a 20% planning reserve to 72 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.

Include tool definitions, source files and tool results in the context budget. Use the checkpoint's chat and tool-call format when testing your agent.

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.
