Qwen3 14B: GPU requirements and hosting
A Qwen text model between the smaller and larger dense checkpoints. Compare it on your own assistant or coding prompts before committing to a larger machine.

Runtime profiles and requirements
These profiles have different memory and context settings. Selecting a runtime updates the figures below; a shared model name does not make their requirements interchangeable.

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 14B total parameters, 16-bit weights alone occupy about 28 GB (parameters × 2 bytes). The shared sizing helper rounds a 20% planning reserve to 34 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.
See the assumptions →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.
Explore machinesBefore deployment
Test the workload you need.
Hold precision, thinking mode and context fixed when comparing runtimes. An Ollama default download and an operator-managed vLLM checkpoint are different configurations.
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.
