Qwen vs GPT
Open-Source Giant vs OpenAI
Alibaba's Qwen3 is open-source, self-hostable, and costs a fraction of GPT. But can it match OpenAI's flagship on YOUR tasks? Here's the full comparison.
Bottom line: Qwen3-235B delivers strong reasoning at a fraction of GPT-5's cost — output tokens are 16x cheaper. GPT-5 leads on multimodal tasks, ecosystem depth, and tool integrations. For text-only workloads where budget matters, Qwen is a serious contender. Benchmark both on YOUR task.
Head-to-Head Comparison
| Feature | Qwen3-235B | GPT-5 |
|---|---|---|
| Provider | Alibaba (via Together AI) | OpenAI |
| License | Apache 2.0 (open-source) | Proprietary |
| Context Window | 262K tokens | 400K tokens |
| Input Price | $0.20/M tokens | $1.25/M tokens |
| Output Price | $0.60/M tokens | $10.00/M tokens |
| Input Modalities | Text only | Text, Images |
| Self-Hosting | Yes | No |
| Multilingual (CJK) | Excellent | Good |
Where Qwen Wins
Cost Efficiency
Qwen3-235B at $0.20/$0.60 per million tokens is 6x cheaper on input and 16x cheaper on output than GPT-5. For high-volume production workloads, that's the difference between a $5,000/month bill and a $400/month bill.
Open Source & Self-Hosting
Apache 2.0 licensed. Self-host on your own infrastructure for maximum data privacy and zero API costs. Fine-tune for your domain. No vendor lock-in.
Where GPT Wins
Ecosystem & Multimodal
Image input, Assistants API, fine-tuning, Azure deployment, and the largest third-party ecosystem. GPT-5 handles multimodal tasks that Qwen's text-only API cannot.
Reliability & Tooling
OpenAI's API has industry-leading uptime, developer tools, and enterprise support. Qwen via Together AI is reliable but the ecosystem is less mature.
Budget Comparison
| Model | Input $/M | Output $/M | Context | Best For |
|---|---|---|---|---|
| Qwen 2.5 7B Turbo Alibaba / Together | $0.30 | $0.30 | 32K | Ultra-budget simple tasks |
| Qwen3-235B (tput) Alibaba / Together | $0.20 | $0.60 | 262K | Budget with strong reasoning |
| GPT-4o mini OpenAI | $0.15 | $0.60 | 128K | Budget with image support |
| GPT-5 Mini OpenAI | $0.25 | $2.00 | 400K | Budget with large context |
GPT-4o mini edges out Qwen on input price ($0.15 vs $0.20) but Qwen3-235B has a larger context window (262K vs 128K). The right choice depends on your specific workload. Calculate costs →
"We switched our CJK translation pipeline from GPT-4o to Qwen3-235B. Accuracy improved on Chinese and Japanese tasks, and costs dropped 85%. For our English-only customer support pipeline, GPT still wins on quality."
FAQ
Is Qwen3 really open source?
Yes — Qwen3 models are released under Apache 2.0 license. You can self-host, fine-tune, and deploy commercially. API access is available via Together AI and other hosts.
Does Qwen support images?
Qwen3 text models are text-only via API. GPT-5 supports text and image input. For multimodal tasks, GPT has the advantage.
Can I test Qwen vs GPT on my own task?
Yes — that's exactly what OpenMark AI does. Run a free benchmark comparing both on YOUR prompts with deterministic scoring.
Why Teams Use OpenMark AI
Not just the big 3. Compare models from every major provider in the same run — all in one place.
Every benchmark hits live APIs and returns actual tokens, actual latency, actual costs. Not cached or self-reported.
Structured, repeatable metrics you can trust. Not LLM-as-judge, where the evaluator is as unreliable as what's being evaluated.
No accounts with providers required. OpenMark AI handles every API call — just describe your task and run.
