claude-opus-4-7

Quality-first Claude model for complex reasoning, long documents, agent decisions, and careful code review.

Overview

  • Claude Opus 4.7 is positioned in the current GPT88 catalog as a flagship Claude model for complex reasoning, long-document understanding, and difficult task decomposition.
  • It is a quality-first candidate when complex inputs, logical completeness, and reduced rework matter more than receiving the fastest response.
  • Model access and the exact limits of context, vision, tools, and sampling parameters must still be confirmed for the current GPT88 route.

Best Use Cases

  • Use it for long materials, long-running conversations, or multi-turn planning
  • Evaluate it when output quality, logical completeness, and clear explanations are important
  • Place it in agent or tool-use workflows that require difficult decisions
  • Test it on quality-sensitive workflows that combine text and image inputs

Integration Notes

  • OpenAI-compatible tools can use https://api.gpt88.cc with model set to claude-opus-4-7.
  • Claude- or Anthropic-style tools such as Claude Code should use the same GPT88 Base URL and the request format expected by that client.
  • Call GET /v1/models and send a minimal request before adding long documents, images, or a large tool set.
  • Use a fixed evaluation set when comparing Claude Opus 4.7 with Opus 4.8 or a lighter Claude model.

Usage Notes

  • Availability, pricing, context limits, rate limits, routes, permissions, vision, and tool support are determined by the current GPT88 console configuration.
  • A flagship positioning does not guarantee the best latency or usage profile for every workload; compare a lighter model where throughput matters.
  • Introduce model changes through a staged rollout and measure errors, tool-call reliability, quality, latency, and usage before expanding traffic.

Endpoint Path

POSThttps://api.gpt88.cc/v1/chat/completions

The endpoint path is determined by the model category. Chat, image, video, and audio models use different endpoints.

Send requests with Authorization: Bearer <API_KEY>. See Chat Completions API for the full parameter reference.

API Docs

Endpoint
POST /v1/messages or POST /v1/chat/completions
Model ID
claude-opus-4-7
Content-Type
application/json
Protocol
Claude family model. Claude-native tools should prefer the Anthropic Messages protocol; OpenAI-compatible tools can use the compatibility path.
Base URL
Use https://api.gpt88.cc for Claude Code / Anthropic SDK, OpenAI SDK, Cursor, and cURL.

Headers / Auth

  • AuthorizationstringRequired
    Send Bearer <GPT88_API_KEY>. Create the API key in the gpt88.cc console.
  • Content-TypestringRequired
    Request body format. Audio transcription uploads use multipart/form-data.
    Default:application/json
  • Acceptstring
    Non-streaming requests return JSON; streaming chat requests return SSE chunks.
    Default:application/json or text/event-stream

Chat Protocol Differences

For chat models, the protocol used by the client matters as much as the model name. Claude Code / Anthropic SDK and OpenAI SDK build different request paths.

OpenAI Compatible
Base URL
https://api.gpt88.cc
Endpoint
POST /v1/chat/completions
Body
{ "model": "claude-opus-4-7", "messages": [...] }
Anthropic / ClaudeRecommended
Base URL
https://api.gpt88.cc
Endpoint
POST /v1/messages
Body
{ "model": "claude-opus-4-7", "messages": [...] }

This model is in the Claude family. Claude Code, Anthropic SDK, OpenClaw, and similar tools should prefer the Anthropic / Claude path.

Request Parameters

The fields below are generated by model category. Pricing, context limits, rate limits, and available routes should be confirmed in the gpt88.cc console.

  • modelstringRequired
    Current model ID: claude-opus-4-7. Preserve the exact casing when copying.
  • messagesarray<Message>Required
    Conversation history. Each message includes role and content.
  • streamboolean
    Enable SSE streaming. Useful for chat interfaces and long responses.
    Default:false
  • temperaturenumber
    Sampling temperature. Higher values produce more variation; production workloads usually start with a fixed value.
    Default:1
  • max_tokensinteger
    Maximum output tokens for this request. Real context limits should be confirmed in the console.
  • response_formatobject
    Structured output config, for example { "type": "json_object" }.
  • toolsarray<Tool>
    Function-calling tool definitions. Availability depends on the model and account configuration.

Response Fields

Response bodies generally follow OpenAI-compatible shapes. Media models may return async task IDs or resource URLs.

  • idstringRequired
    Unique completion ID for tracing and debugging.
  • objectstringRequired
    Usually chat.completion or a streaming chunk type.
  • modelstringRequired
    Actual model ID that handled inference.
  • choicesarray<Choice>Required
    Generated choices including message, delta, and finish_reason.
  • usageobject
    Token usage statistics. Streaming calls may return this only at the end or in non-streaming mode.

Status Codes

  • 200OKRequired
    Request succeeded. See the response field table above for the response body shape.
  • 400Bad Request
    Invalid request fields, such as missing required fields, unsupported image size format, or unsupported file type.
  • 401Unauthorized
    API key is missing, invalid, or malformed.
  • 404Not Found
    Endpoint or model not found. Confirm the path is /v1/chat/completions and the model ID is claude-opus-4-7.
  • 429Rate Limited
    Rate limit, concurrency cap, or insufficient balance. Check the console for the current allowance.
  • 5xxUpstream Error
    Upstream or request failure. Retry with the same Base URL and keep the request ID for debugging.

Errors and Troubleshooting

  • 401: verify Authorization is Bearer <API_KEY> and the key is still valid.
  • 404: confirm the endpoint is /v1/chat/completions and the model ID claude-opus-4-7 is available in the console.
  • 429: reduce concurrency, shorten requests, or check balance and quota in the console.
  • 5xx: retry with the same Base URL and keep the request ID for debugging.
