20260417 Claude Opus 4.7 Now Supported

[New Model Launch] CloudRouter Now Supports the Claude Opus 4.7 Model

Dear CloudRouter users,

CloudRouter now officially supports the Claude Opus 4.7 model. The resource availability and usage instructions for each channel are described below.

1. Channel Support Status

Channel	Opus 4.7 Support	Primary Model
x6 Official Flagship Channel	Ample resources, fully available	Opus 4.7
x4 Official Premium Channel	Only a limited number of accounts are open for users to try; resources are being continuously replenished	Opus 4.6

2. Usage Guide

x6 Official Flagship Channel

For Claude Code users:

Run /model in Claude Code:

• If the Opus 4.7 option already appears in the list, you can select and use it directly
• If the option does not appear, please upgrade Claude Code to the latest version and try again

For API users:

When calling the x6 channel via API, set the model name to:

claude-opus-4-7

x4 Official Premium Channel

The primary model for this channel is still Opus 4.6. Opus 4.7 account resources are limited and available for trial only.

If you only see Opus 4.7 and not Opus 4.6 in the /model list, you can switch back to 4.6 using the following command:

/model claude-opus-4-6

We are continuously replenishing the Opus 4.7 resources for the x4 channel. Thank you for your patience.

3. API Parameter Differences

CloudRouter only provides model relay services; request parameters must remain consistent with the official Anthropic specification. When switching from Opus 4.6 to Opus 4.7, the following breaking changes apply; otherwise a 400 error will be returned.

⚠️ The following content is for reference only. Please refer to the official Anthropic migration guide for the authoritative details.

Item	Opus 4.6	Opus 4.7
Extended Thinking	thinking: {type: "enabled", budget_tokens: N}	Must be changed to thinking: {type: "adaptive"}, and the thinking depth is controlled via output_config.effort (low/medium/high/xhigh/max)
Sampling Parameters	Supports temperature / top_p / top_k	Non-default values are not supported and must be removed from the request, otherwise it will error
Thinking Content Display	Returns a summarized summary by default	Omitted by default; to display thinking content, you must explicitly set thinking.display: "summarized"
Tokenizer	Legacy tokenizer	Uses a new tokenizer; the same text produces approximately 1x to 1.35x more tokens. It is recommended to raise max_tokens and re-evaluate costs
Prefill (assistant prefill)	Removed	Still not supported; use structured outputs or system prompts instead

Capabilities that remain unchanged: 1M context window, 128k maximum output, Prompt Caching, Batch API, Files API, PDF / Vision, and the full suite of tool calls (bash / code execution / computer use / text editor / web search / web fetch / MCP / memory).

4. Friendly Reminders

• We recommend upgrading Claude Code to the latest version to get full support for Opus 4.7
• If you encounter any issues during use, please feel free to contact our technical support team

Thank you for your support and trust!
