Llama 3.1 8B GPU requirements and hosting.
A text assistant checkpoint for chat, summarization and retrieval-backed answers. Start here when you want a smaller Llama deployment to evaluate with your own prompts.

The creator identifies the original checkpoint. Runtime profiles may use separately packaged artifacts; their publishers and configuration can differ. Check the selected profile below.
Configuration matters
Choose a runtime profile.
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.

- 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.
Memory components
Account for the whole workload.
ollamallama3.1:8b
Total GPU allocation Not established
Weights = 8 billion parameters × 2 bytes. This reference does not describe the selected artifact’s unrecorded precision. Cache and runtime reserve need the exact workload. Band widths are schematic, not memory shares; the separate 8 GB catalog threshold is guidance. A multi-GPU total needs a supported model split and topology.
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.

Memory-based machine candidate
1× RTX 5090
32 GB total GPU memory · 32 GB per GPU
8 GB sizing figure · 32 GB installed GPU memory. Remaining capacity is not a measured runtime reserve.
This configuration includes 64 GB system RAM. Memory capacity alone does not establish runtime compatibility, latency or throughput.

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.

The reviewed revision identifies the source used for this guide. It is not a claim that this revision is installed on a B3IQ machine. Review the publisher's current license and acceptable-use terms for your application.
Guide updates and corrections.
These are changes to the guide. Source-review dates and workload-test evidence are recorded separately.
- · Update
Added creator attribution and a canonical checkpoint overview. The guide now explains how the original creator differs from a runtime artifact publisher.
