Deep dive
The capability footprint differs most on vision: Claude Sonnet 4.6, multimodal input: Claude Sonnet 4.6, reasoning mode: Claude Sonnet 4.6, function calling: Claude Sonnet 4.6, tool use: Claude Sonnet 4.6, structured outputs: Claude Sonnet 4.6, and code execution: Claude Sonnet 4.6. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Sonnet 4.6 lists $3/1M input and $15/1M output tokens on the cheapest tracked provider, while Llama Guard 3 1B lists $0.10/1M input and $0.10/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Llama Guard 3 1B lower by about $6.50 per million blended tokens. Availability is 6 providers versus 1, so concentration risk also matters.
Choose Claude Sonnet 4.6 when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose Llama Guard 3 1B when provider fit and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which has a larger context window, Claude Sonnet 4.6 or Llama Guard 3 1B?
Claude Sonnet 4.6 supports 1m tokens, while Llama Guard 3 1B supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
