Frequently asked questions

Anthropic FAQs

What are the latest Anthropic Claude models?

The Claude 5 family includes Fable 5.1 and Opus 5 (frontier reasoning), Claude Sonnet 5 (balanced), and Haiku 4.5 (efficient tier). Claude Code is a specialised agentic coding product. Check docs.anthropic.com/en/docs/about-claude/models for current pricing.

What is the context window for Claude 5 models?

Claude 5 Opus, Fable 5, and Mythos 5 all support 1M+ token context windows, enabling full-codebase and book-length document analysis in a single call.

How does Anthropic prompt caching work?

Anthropic's prompt caching lets you mark portions of your prompt (system prompts, documents, tool definitions) to be cached server-side. Cached tokens are billed at 10% of the standard input price after the first write, making repeated long-context calls dramatically cheaper.

RouterPlus FAQs

Are RouterPlus prices guaranteed?

No. RouterPlus prices shown are published base catalog rates. Actual price depends on the selected route and context. 27 models have numerically different route prices. Check route details before production use.

What models does RouterPlus offer?

RouterPlus offers 117 text models including Claude 5 (Fable 5.1, Opus 5-5, Sonnet 5-5, Haiku 5-5), GPT-6 Astra, Gemini 3.x, Grok 4.x, Kimi K3, GLM-5.3, Qwen 3.8 Max, DeepSeek V4 Pro, Mistral Large 4, and many more. See the model table for current rates.

What is the RouterPlus API base URL?

Provider category context

Anthropic is a frontier lab, founded in 2021. RouterPlus is a inference api. Anthropic as a frontier lab trains and serves its own proprietary models. RouterPlus as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers but without access to proprietary frontier models.

How to choose between them

Choose Anthropic if you need claude 5 family leads on coding and reasoning benchmarks. Choose RouterPlus if you need wide catalog: 117 text models including claude, gpt, gemini, grok, kimi, glm, qwen, mistral, and more. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
