Test Everything. Pick the Best.
Our Testing Philosophy
We don't pick favorites based on brand names. Every model gets tested: Qwen 3 Coder, GPT OSS, OpenAI, and Gemini. We measure speed, quality, reasoning ability, and real-world performance.
Our conclusion? Gemini and Qwen 3 consistently deliver the best balance of speed and quality. GPT OSS is lightning fast but often produces poor results. OpenAI has decent quality but slower performance.
We choose the right model for each task, not the most popular brand.
What Quality AI Actually Means
After testing hundreds of thousands of requests across all major models, we've learned what separates good AI from great AI:
- Consistent reasoning - Not just pattern matching
- Natural language - Responses that don't scream "AI"
- Context understanding - Gets nuance and subtext
- Reliable performance - Same quality every time
Speed vs Quality: The Real Trade-offs
Here's what our testing revealed about each model's performance:
🥇 Gemini 2.5 Flash
- • Best overall quality
- • 1M token context window
- • Excellent for RAG tasks
- • Fast and cost-effective
- • Multimodal capabilities
🥈 Qwen 3 72B
- • Natural, human-like responses
- • Strong reasoning capabilities
- • Good speed-quality balance
- • Less corporate "AI-speak"
- • Creative problem solving
⚡ GPT OSS (Cerebras)
- • Incredibly fast (3000 TPS)
- • Low cost per token
- • BUT: Inconsistent quality
- • Often generic responses
- • Good for simple tasks only
📊 OpenAI GPT-4
- • Decent quality responses
- • Wide knowledge base
- • BUT: Slower API responses
- • Higher costs
- • More templated output
