Meta's open-weights frontier model. Self-host GPT-5-class intelligence.
Meta's open-weights frontier model. Self-host GPT-5-class intelligence. Llama 4 405B (February 2026) is Meta's largest open-weights release yet — matches GPT-5 on most reasoning benchmarks, runs on 8x H100s, and is free for commercial use. The first time open-weights is genuinely competitive at the frontier.
Who it's for: enterprises with strict data residency requirements, anyone who can't send data to OpenAI/Anthropic, researchers and fine-tuners
Download, fine-tune, distill, and self-host commercially. The license is the most permissive of any frontier model.
Mixture-of-experts architecture — only 17B active per token, but the full 405B knowledge is available on demand.
Run on your own hardware. Logs never leave your VPC. Critical for finance, healthcare, and government.
Supports text, image, and audio. 128K context window — less than Gemini but more than GPT-5's default.
Meta ships reference fine-tuning recipes. Train on a single 8x H100 node for most domain adaptations.
Llama 4 405B is the first open-weights model where you don't have to apologize for the quality gap. It matches GPT-5 on most benchmarks, lags Claude Sonnet 4 on the hardest agentic tasks, but wins on sovereignty and cost-at-scale. If your data can't leave the building, this is your model. If you're a startup with no GPU budget, keep using Claude or GPT-5.
Rating: ★ 4.6/5 · Best for: enterprises with strict data residency requirements, anyone who can't send data to OpenAI/Anthropic, researchers and fine-tuners
