- License
- Llama 4 Community LicenseA custom commercial license governs the checkpoint, with attribution, redistribution, derivative naming and acceptable-use obligations. A release-date monthly-active-user threshold greater than 700 million requires a separate Meta grant. Weight download requires accepting the publisher's access conditions; listing the model does not accept those terms on Aguasto's behalf.Meta Llama4Scout17B16EInstruct official model card (external source) · Llama4Community License (external source)
Theoretical weight-memory footprint
Using the publisher's approximately 109 billion total parameters at 16 bits per parameter gives 218 GB (203.0 GiB) of nominal weights.
weight GB = total parameters in billions × bits per weight / 8This estimate excludes KV cache, activations, quantization metadata, non-weight buffers and serving overhead. It is not a tested GPU fit. MoE routing activates only part of the network per token while the complete expert weights still need storage.
Explore the memory estimatorQuantization
The model card's Transformers example loads BF16 and discusses quantization as a separate deployment choice. Its conditional hardware example does not establish a full-context or production-fit result. Aguasto has not downloaded or tested gated weights.
Meta Llama4Scout17B16EInstruct official model card (external source) · Llama4Community License (external source)Serving considerations
- The publisher distinguishes 109B total from 17B activated parameters. Expert routing reduces activated work per token; it does not make the full checkpoint a 17B weight-storage problem.
- The model card advertises 10M context, but the exact numeric checkpoint position limit was not readable without gated access. The numeric context field stays unknown rather than turning the rounded advertisement into an exact config value.
- Native early-fusion text/image inputs require the correct processor and chat template. The publisher describes testing image understanding up to five images; additional-image behavior needs a separate evaluation.
- The card provides a Transformers implementation path. Model-specific vLLM/SGLang compatibility is not asserted by this record; supported model architecture, version, attention and parallelism must be checked independently.
- No Aguasto inference offering, deployment, benchmark, GPU fit or throughput is claimed. The record is a technical research reference for this exact checkpoint.
Framework documentation
These are third-party documentation starting points. Support depends on the exact checkpoint, runtime version and hardware.
Sources & verification
The register preserves each source's publication and verification date. Manufacturer claims and documentation are attributed; Aguasto has not run the cited products in production.
