AI model family

Llama 4 model family

Meta's downloadable Llama 4 family, with multimodal model variants and provider-specific hosting paths.

Editorially reviewedVerified 2026-08-112 official or primary sources

What the family record covers

Meta's Llama documentation currently identifies Llama 4 Scout and Llama 4 Maverick as multimodal models for image and text understanding. The family can be obtained directly or through multiple model and cloud partners.

Downloadable weights create deployment choices that hosted-only comparisons miss. Hardware, quantization, serving software, prompt format, safety layers, and operator updates become part of the evaluated system.

Documented access paths

  • Model access directly from Meta or named distribution partners
  • Self-managed or third-party hosted inference under the applicable model license
  • Separate Llama Guard resources for safety-layer evaluation

Capabilities to verify

  • Image-and-text behavior for the selected checkpoint and prompt format
  • Throughput, memory, and latency on the actual serving stack
  • Quantization impact on task quality and structured output
  • Safety controls, monitoring, and upgrade ownership in the chosen deployment

Decision questions

  1. Will the organization self-host or use a named inference provider?
  2. Which checkpoint, license terms, quantization, and serving version define the pilot?
  3. Who owns safety-layer configuration, patching, and model replacement?

Evaluation cautions

  • The same checkpoint can behave differently across serving and quantization choices.
  • Open or downloadable access does not remove license, security, or governance obligations.
  • Provider benchmark claims need independent replication on the intended stack.

Latest releases

IndexNow root-proof request compatibility

After v4.3.3, the exact root-level {key}.txt proof returned HTTP 200, but a full request carrying keyLocation still returned HTTP 403; a minimal homepage request with the same production key and no keyLocation returned HTTP 202. This release omits that field, while the automatic full run and idempotent rerun remain deployment checks.

IndexNow key-proof compatibility

Changed IndexNow verification to the official root-level {key}.txt convention after the first production notification returned HTTP 403; revalidation remains pending, while the website, sitemaps, and Bing sitemap processing are unaffected.

Bing sitemap discovery and IndexNow change notifications

Prepared canonical sitemap discovery for Bing and added automatic IndexNow change notifications while keeping segmented sitemaps authoritative and making no claim that a notified URL has been crawled or indexed.
