Data policy

Prompt retention
Unknown — we could not confirm
Training
Not used for training

"Unknown" does not mean "safe". It means we could not confirm it.

Whether a provider trains on prompts is a declared value from our terms with them. Retention is determined from the upstream listing for every host this model can reach. Neither is guessed.

How MiMo-V2.6-Pro actually answers

Real responses to our standard prompts, recorded on FastMetal.

Count the number of 'r's in 'strawberry'

Count the number of 'r's in 'strawberry'. Explain your reasoning step by step.

# Counting the 'r's in "strawberry" ## Step 1: Spell out the word letter by letter | Position | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | |----------|---|---|---|---|---|---|---|---|---|----| | Letter | s | t | r | a | w | b | e | r | r | y | ## Step 2: Identify every 'r' - **Position 3** → **r** ✅ (1st 'r') - **Position 8** → **r** ✅ (2nd 'r') - **Position 9** → **r** ✅ (3rd 'r') All other letters (s, t, a, w, b, e, y) are not 'r'. ## Answer There are **3** 'r's in "strawberry."

Debug This Error

I'm getting the following error in my Node.js application: TypeError: Cannot read properties of undefined (reading 'map') at UserList (/app/components/UserList.js:12:25) at renderWithHooks (/app/node_modules/rea…

# Fixing `Cannot read properties of undefined (reading 'map')` ## The Problem The `users` prop is `undefined` when the component renders. This happens because `.map()` is being called on something that doesn't exist — JavaScript can't iterate over `undefined`. This typically occurs when: - The parent component doesn't pass the `users` prop at all - The data is still loading (e.g., from an API call) - A destructuring default doesn't exist ## The Fix ### Option 1: Provide a default value (simplest) ```jsx function UserList({ users = [] }) { return ( <ul> {users.map(user => <li key={user.id}>{user.name}</li>)} </ul> ); } ``` ### Option 2: Add a safety check with conditi…

Code Review

Please review the following Python function and suggest improvements for readability, performance, and best practices: def get_data(url, retries=3): import requests import time for i in range(retries):…

# Code Review: `get_data` Function ## Issues Identified Here's my review organized by category, with a final improved version at the end. --- ### 🔴 Best Practices 1. **Imports inside the function** — `import requests` and `import time` are executed on *every* call. Move them to the top of the file (module-level). 2. **Bare `except:`** — This catches *everything*, including `KeyboardInterrupt` and `SystemExit`. Always catch specific exceptions. 3. **`== True` comparison** — Verbose and unnecessary. Use the object's truthiness directly. 4. **No logging** — Silent failures make debugging nearly impossible. 5. **Magic numbers** — `timeout=10` and `time.sleep(2)` are unexplained constan…
