+  const { question, solution, userSolution, userMessage, apiKey, baseUrl, modelId, mode = "chat" } = req.body;

  const openai = new OpenAI({
    apiKey: apiKey,
+    baseURL: baseUrl || "https://api.openai.com/v1",
  });


baseUrl is taken directly from the request body and used as the OpenAI client baseURL. Because this route is unauthenticated, this creates an SSRF / proxy primitive and can also exfiltrate the caller-supplied apiKey to an arbitrary host via the Authorization header. Consider restricting baseUrl to an allowlist (or a server-side config), enforce https, and explicitly block localhost/private/metadata IP ranges; also consider rejecting non-POST requests here to reduce abuse surface.

  apiKey                  String?     @default("null")
+  apiBaseUrl              String?     @default("https://api.openai.com/v1")
+  modelId                 String?     @default("gpt-4o")


The Prisma schema adds apiBaseUrl and modelId, but there’s no corresponding migration checked in under prisma/migrations. If the project relies on migrations (it looks like it does), this will cause schema drift / deploy failures. Please generate and commit a migration for these new columns.

The Base URL field is rendered as type="password", but this value isn’t a secret. Using a password input can confuse users and password managers and harms accessibility. Consider using type="text" (and optionally keep a separate “reset to default” affordance) instead of hide/show behavior here.

Suggested change

type={isBaseUrlVisible ? "text" : "password"}

id="apiBaseUrl"

defaultValue={data.apiBaseUrl}

placeholder="https://api.openai.com/v1"

className="w-full px-3 py-2 bg-[#2A303C] border border-[#3A4150]/70 rounded-md shadow-sm outline-none focus:outline-none focus:border-[#06b6d4]/70 focus:ring-1 focus:ring-[#3b82f6]/50 transition-all duration-200 text-primary h-11"

The Model ID field is rendered as type="password", but model identifiers aren’t sensitive. This makes it harder to review/edit the value and can interfere with autofill/password managers. Consider switching this input to type="text" and dropping the hide/show toggle.

Suggested change

type={isModelIdVisible ? "text" : "password"}

id="modelId"

defaultValue={data.modelId}

placeholder="gpt-4o"

className="w-full px-3 py-2 bg-[#2A303C] border border-[#3A4150]/70 rounded-md shadow-sm outline-none focus:outline-none focus:border-[#06b6d4]/70 focus:ring-1 focus:ring-[#3b82f6]/50 transition-all duration-200 text-primary h-11"

hey @hussiiii, loved the project. added multi-llm support in the project, right now default is openai with gpt-4o. but i added option of adding custom opeai-compatible model, merging this pr will add this feature. so user can add any openai-compatible models, like open source models too.

Also When you deploy this with your database configured, run:

npx prisma migrate dev --name add_api_config

thanks

added multi-llm support
