Claude Sonnet 4.6 — Balanced AI Model on Craze

About Claude Sonnet 4.6

Claude Sonnet 4.6 sits in the middle of the Claude lineup and is the one most teams end up living in. It's a strong reasoner that's still fast and affordable enough for everyday chat, code review, drafting, and the kind of agent work where you don't want to think about cost per call.

Like the rest of the Claude family, Sonnet 4.6 supports tool calling, MCP, vision, and streaming on Craze. Connect Gmail, Calendar, Notion, Slack, Linear, GitHub — Sonnet reads context and takes action without you wiring integrations.

If Opus is the deep-thinking specialist and Haiku is the speed demon, Sonnet is the workhorse you'll actually default to. Most Craze users keep Sonnet selected for chat and only swap up to Opus when a task genuinely needs the extra reasoning, or down to Haiku when latency matters more than depth.

What Claude Sonnet 4.6 is good at

Balanced intelligence and speed

Strong enough to handle most reasoning tasks while being quick and affordable enough to use it for everything. The default Claude tier most teams pick on Craze.

Solid code review and editing

Reads diffs, explains intent, and writes clean refactors. A reliable model behind a code-review or pair-programming agent.

Everyday writing and chat

Holds tone over long conversations and produces clean drafts on the first pass. Useful as the default chat model for a team that switches tasks all day.

Tool use, MCP, and structured output

Calls functions, returns strict JSON, and works with MCP servers — same agentic surface as Opus, at a fraction of the cost.

Vision and document reading

Reads screenshots, charts, and PDFs alongside your text. Strong for design feedback, document Q&A, and quick data sanity checks.
