See Them Answer the Same Question
We asked both models the same prompt. Here’s what they said.
“What are the most effective strategies for learning a new language as an adult, and how long does it realistically take to become conversational?”
What are the most effective strategies for learning a new language as an adult, and how long does it realistically take to become conversational?
These are questions where I can give you honest, evidence-based answers rather than just encouraging platitudes.
Effective Strategies (with realistic assessments)
What actually works:
- Comprehensible input - consuming content slightly above your current level (reading, listening)
- Spaced repetition for vocabulary (Anki, etc.) - genuinely research-supported
- Speaking practice early and often - discomfort is part of the process
- Consistent daily practice beats occasional long sessions significantly
- Focusing on high-frequency vocabulary first (top 1000-2000 words cover most conversation)
What's overhyped:
- Apps like Duolingo alone - good supplement, insufficient as primary method
- "Immersion" without structured learning for most adults
- Claims that grammar study is useless - it helps most adults when balanced with practice
Realistic Timeline
The honest answer depends heavily on:
- Language distance from your native language - Spanish for English speakers is much faster than Japanese or Arabic
- Daily time invested
- What "conversational" means to you
Rough estimates for English speakers:
- Romance languages: 6-12 months of serious study for basic conversation
- Germanic languages: similar range
- Japanese/Arabic/Mandarin: typically 2-4+ years
Important Honest Note
Most people underestimate required effort and overestimate app-based progress. Consistent daily practice of 30-60 minutes beats weekend marathons considerably.

Claude Is Better for Writing
Claude is the clear winner for writing tasks. Anthropic has specifically optimized Claude for nuanced, natural prose that follows instructions precisely — a combination that's hard to beat for drafting documents, reports, or long-form content. Claude's outputs tend to feel more polished and human, with better tonal control and stylistic consistency. Qwen is a capable writer but lacks the same refinement in English prose quality. For anyone who writes professionally or frequently, Claude's edge here is meaningful.
Read full comparisonClaude Is Better for Coding
Claude edges out Qwen on coding, backed by a higher SWE-bench Verified score of 79.6% versus Qwen's 76.4%.
