Meta Llama
Meta's open-source large language model family for building custom AI applications and workflows.
What it does
Meta's Llama series is the leading family of open-source large language models, released with weights that developers can download, modify, and deploy on their own infrastructure. Llama 3 models range from 8B to 405B parameters and match or approach proprietary model quality on many benchmarks. The open-weights approach makes Llama the foundation of thousands of fine-tuned models and AI products built by the developer community.
Why AI-NATIVE
Llama is a foundation model released specifically as an AI capability; Meta built it as the core of its AI research and product strategy.
Best for
Small technical teams fine-tune Llama on their own data for specialized use cases - customer service, document processing, domain-specific Q&A - without ongoing API costs.
Mid-market companies self-host Llama for cost control at scale and data privacy - avoiding per-token costs that compound quickly with high-volume applications.
Enterprises with data sovereignty requirements, regulated data, or very high volume use cases deploy Llama on private infrastructure for full control with no data leaving their environment.
Limitations
Meta Llama is an open-weight model, not a product — deploying it in production requires infrastructure, fine-tuning, safety evaluation, and ongoing maintenance that demands dedicated engineering resources.
The base Llama models have fewer safety guardrails than commercial alternatives — production deployments targeting consumer-facing use cases need additional alignment and moderation work.
Meta provides the model weights but no production support, uptime guarantees, or incident response — organizations need a third-party hosting arrangement or internal SRE capability to operate it reliably.
