gpt-6-sol

New GPT88 featured GPT-6 Sol route for complex coding, deep reasoning, and long-running agent workflows.

Get API Key on gpt88.ccQuickstart

Overview

  • GPT-6 Sol is the complex-work route in OpenAI’s latest GPT-6 family, intended for deeper reasoning, code understanding, tool use, and multi-stage execution.
  • GPT88 has added GPT-6 Sol to the featured lineup so developers can evaluate complex coding, research, and agent workflows through the same OpenAI-compatible integration.
  • This page does not hardcode dynamic context, limits, tools, vision support, or pricing. Confirm the current API key access with GET /v1/models and the GPT88 console.

Best Use Cases

  • Handle complex code generation, refactoring, debugging, and code review
  • Run agents that call tools, inspect results, and progress through multiple stages
  • Produce technical plans, research analysis, and high-quality structured output
  • Compare it with gpt-6-astra, gpt-6-luna, or a validated fallback on a fixed workload
  • Use it for high-value work where access, stability, latency, and usage can be validated first

Integration Notes

  • Use the GPT88 OpenAI-compatible base URL and set model to gpt-6-sol.
  • Call GET /v1/models to confirm that the current API key can access gpt-6-sol before sending a minimal non-streaming request.
  • Enable plain text, structured output, streaming, tools, and long context progressively while recording success rates and error types.
  • For agent tasks, keep the tool schema, permissions, initial context, and acceptance criteria fixed; do not conflate model quality with harness or tool permissions.

Usage Notes

  • gpt-6-sol is a newly launched model and the current local backend catalog has not synced it yet. Access, groups, quota, pricing, limits, and routes are determined by the GPT88 console and API key.
  • Keep a validated fallback route until the model passes your own quality, latency, cost, and reliability checks.
  • High-risk code, database, payment, permission, and production actions still require independent review, deterministic tests, and human authorization.

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/chat/completions
Model ID
gpt-6-sol
Content-Type
application/json
Protocol
OpenAI-compatible chat completions endpoint with streaming and non-streaming output.
Base URL
Use https://api.gpt88.cc for 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 CompatibleRecommended
Base URL
https://api.gpt88.cc
Endpoint
POST /v1/chat/completions
Body
{ "model": "gpt-6-sol", "messages": [...] }
Anthropic / Claude
Base URL
https://api.gpt88.cc
Endpoint
POST /v1/messages
Body
{ "model": "gpt-6-sol", "messages": [...] }

This model is usually best accessed through the OpenAI-compatible protocol. Only use the Anthropic-style path when the target tool explicitly requires it.

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: gpt-6-sol. 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 gpt-6-sol.
  • 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 gpt-6-sol 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.
