How Claude 5 Sonnet and Qwen-Max differ
What the numbers mean in practice when choosing between Claude 5 Sonnet and Qwen-Max.
-
Qwen-Max is 47% cheaper on input tokens ($1.6 vs $3 per million), which adds up quickly in document-heavy workloads.
-
Qwen-Max is 57% cheaper on output tokens ($6.4 vs $15 per million) - the bigger factor for tools that generate long documents.
-
Claude 5 Sonnet's 1M tokens context window is roughly 30.5x larger than Qwen-Max's 32.8K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
Claude 5 Sonnet
1. Anthropic's most agentic Sonnet yet
- A substantial upgrade over Sonnet 4.6 on reasoning, tool use, coding, and knowledge work - narrows the gap to Opus 4.8 while staying at Sonnet pricing.
- Early partners describe it finishing multi-step jobs end to end where prior Sonnet models used to stall halfway.
2. Clear benchmark gains over Sonnet 4.6
- 63.2% on SWE-bench Pro (vs 58.1%), 80.4% on Terminal-Bench 2.1 (vs 67.0%), 81.2% on OSWorld-Verified (vs 78.5%), and 57.4% on Humanity's Last Exam with tools (vs 46.8%).
- On the GDPval-AA v2 knowledge-work benchmark it edges past Opus 4.8 (1,618 vs 1,615).
3. Near-Opus performance at a fraction of the price
- Priced at $3/M input and $15/M output - 40% cheaper than Opus 4.8's $5/$25 - with introductory pricing of $2/$10 through Aug 31, 2026 during the rollout.
- Supports
low,medium,high, andxhigheffort levels, covering a wider cost-performance range than Sonnet 4.6 and matching Opus 4.8 on some tasks at higher effort.
4. Long-context, long-horizon reliability
- Full 1M token context window with up to 128K output tokens.
- Adaptive thinking automatically decides how long to reason; better self-correction, fewer tool errors, and steadier follow-through across long agent sessions in Claude Code and Cowork.
5. Safer and more honest than its predecessor
- Lower rates of hallucination, sycophancy, and misaligned behavior than Sonnet 4.6 on Anthropic's automated safety audits.
- Deliberately limited cyber capability compared with Opus-class models, shipped with cyber safeguards enabled by default.
6. Updated tokenizer
- Uses a new tokenizer (shared with the Opus 4.7/4.8 line) that can map the same text to up to 1.35x more tokens than Sonnet 4.6 - introductory pricing is set so the switch is roughly cost-neutral.
Qwen-Max
1. Strong general-purpose reasoning
- Great for coding, analysis, creation, and multi-step tasks.
2. Stable commercial-grade model
- Predictable output quality and long-term stability.
3. Supports batch operations
- Batch inference is 50% cheaper.
4. Good for production agents
- Reliable instruction following and structured output.

FAQs
Qwen-Max is generally cheaper: $1.6 input / $6.4 output per million tokens, versus $3 / $15 for Claude 5 Sonnet. Actual cost depends on how many tokens your workload reads and writes.
Claude 5 Sonnet has the larger context window at 1M tokens, compared to 32.8K tokens for Qwen-Max. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
