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.
Volcano Engine Doubao FAQs
What is Doubao Seed 2.1?
Doubao Seed 2.1 is ByteDance's latest LLM series, available via Volcano Engine. Pro is the frontier reasoning tier and Turbo is the balanced tier. Both support Chinese and English.
How much does the Doubao API cost?
Doubao Seed 2.1 Pro is $6.00/$30.00 per 1M input/output tokens. Doubao Seed 2.1 Turbo is $3.00/$15.00 per 1M tokens. See the Volcano Engine pricing page for current rates.
Is Doubao available outside China?
