398-402:⚠️ Potential issue | 🟠 Major | 🏗️ Heavy liftUpdate narrative to match the actual implementation.
The text describes a custom
URLLib3Transportclass that no longer exists in the code. The Python code comment (lines 296-299) explicitly states that "Modern Pyodide (>= 0.27.2) shipsopenai,httpx, andurllib3as bundled packages with built-in Emscripten/Fetch transports, so no custom HTTP transport is needed anymore."This section should be rewritten to describe the actual implementation: using the built-in httpx transport with an event hook to strip stainless headers for OpenRouter CORS compatibility.

The conclusion still mentions "GPT-3" but the entire tutorial has been updated to use GPT-5.4-mini. This should be corrected for consistency.

OpenRouter API token is required: change the text at the locations that
currently read "tokens de OpenRouter" and "Necesitas un token de OpenAI" to
explicitly say "token de OpenRouter (OpenRouter API key)". Also ensure any
explanatory text or links referencing authentication align with the code's
base_url="https://openrouter.ai/api/v1" and the prompt label "OpenRouter API
key" so readers aren’t directed to use an OpenAI token by mistake.

| (Necesitas un token de OpenAI) |
There was a problem hiding this comment.
Clarify which API token is required.
There's confusion about which API token users need:
- Line 460 says: "Con este código, puedes probarlo con tokens de OpenRouter"
- Line 463 says: "Necesitas un token de OpenAI"
Since the code uses base_url="https://openrouter.ai/api/v1" (line 339) and prompts for an "OpenRouter API key" (line 214), both links should consistently indicate that an OpenRouter token is required, not an OpenAI token.
