Use QuickSilver Pro from your favorite tool
Anything that speaks the OpenAI Chat Completions API works with QSP. GPT-6.1 Sol also supports the Responses API used by Codex.
The two values you always need
Every tool below just wants these two strings — the rest of the config is the tool's own UI:
Base URL → https://api.quicksilverpro.io/v1
API key → sk-... (from your dashboard)Don't see your tool below? Anything OpenAI-compatible works.
Codex (Responses API)
GPT-6.1 Sol is available through the Responses API used by Codex. Add a QSP provider to ~/.codex/config.toml:
model = "gpt-6.1-sol"
model_provider = "quicksilverpro"
preferred_auth_method = "apikey"
forced_login_method = "api"
model_reasoning_effort = "high"
[model_providers.quicksilverpro]
name = "QuickSilver Pro"
base_url = "https://api.quicksilverpro.io/v1"
wire_api = "responses"
experimental_bearer_token = "<your QSP API key>"Codex sends requests to /v1/responses; the same QSP key and model ID also work through Chat Completions.
Aider (terminal pair-programmer)
Aider speaks OpenAI natively. Point it at QSP with two env vars and a model flag — that's it.
export OPENAI_API_BASE="https://api.quicksilverpro.io/v1"
export OPENAI_API_KEY="$QSP_KEY"
aider --model openai/deepseek-v4.1-flashThe openai/ prefix tells Aider to route through the OpenAI client; everything after it is the QSP model ID (see the list).
Cline / Roo Code (VS Code agent)
Open the Cline (or Roo Code) sidebar → settings cog → API Provider:
API Provider: OpenAI Compatible
Base URL: https://api.quicksilverpro.io/v1
API Key: <your QSP key>
Model ID: deepseek-v4.1-flash (or any QSP model)Reasoning-by-default models (GPT-6.1 Sol, GPT-6 Luna, Claude Opus 5.5, Claude Sonnet 5.5, Gemini 3.8 Flash) work as Cline's "Thinking" provider out of the box.
Continue.dev (VS Code / JetBrains)
Add QSP as a model in ~/.continue/config.json:
{
"models": [
{
"title": "DeepSeek V4 Pro (QSP)",
"provider": "openai",
"model": "deepseek-v4.1-flash",
"apiBase": "https://api.quicksilverpro.io/v1",
"apiKey": "$QSP_KEY"
}
]
}Open WebUI
In Open WebUI: Admin Panel → Connections → OpenAI API, add a new connection:

Key: <your QSP key>Save and reload — all 71 QSP models will appear in the model picker.

LangChain / LlamaIndex / Vercel AI SDK
Pass QSP's base URL into the OpenAI provider for any of these frameworks. Example (LangChain Python):
import os
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(
model="deepseek-v4.1-flash",
base_url="https://api.quicksilverpro.io/v1",
api_key=os.environ["QSP_KEY"],
)Anything else
QSP is OpenAI-compatible — Chat Completions, streaming, tool calling and usage accounting across the catalog, plus the Responses API for DeepSeek V4.1 Flash. Structured output is model-dependent: the Claude models do not support json_schema, so a schema there is advisory and the enforced path is a tool with strict: true — see structured output. If your tool talks to api.openai.com/v1, changing base_url to https://api.quicksilverpro.io/v1 is almost always all you need.
