Meta AI Models

Overview of Meta's AI models: the newer proprietary Muse family, plus the still widely self-hosted, open-weight Llama 4 generation.

Latest: Muse Spark 1.3

Muse Spark 1.3 (Sep 2026) is Meta Superintelligence Labs' most capable model to date, positioned as competitive with current Anthropic/OpenAI frontier models. It marks Meta's shift from fully open Llama weights toward a proprietary model strategy served via the Meta Model API.

Strengths

  • Agentic automation and coding
  • Competitive with frontier labs
  • Multimodal understanding

Best For

  • General-purpose agents
  • Coding automation
  • Meta AI app integrations

Model Lineup

Muse Spark 1.3

Meta's latest proprietary flagship, via the Meta Model API.

Muse Glimmer

Open-weight (Apache 2.0), ~30B local agent model that runs on a single consumer GPU.

Llama 4 Maverick / Scout

Meta's last fully open-weight generation; still widely self-hosted for on-premise and private deployments.

Practical Guidance

  • Use Llama 4 (open weights) when you need full on-prem/self-hosted control; use Muse Spark via the API for the latest capability.
  • Muse Glimmer is a good fit for local, always-on coding/function-calling agents on a single GPU.
  • Adopt guardrails and evaluation suites for safety and reliability.
