Multos Team

With 65+ AI models across 11 providers available, choosing the right one matters. We tested GPT-5.6 Sol, Claude Opus 4.8, and Gemini 3.1 Pro on real-world coding tasks.

GPT-5.6 Sol: Best for Complex Architecture

Strengths: System design, multi-file refactoring, architectural decisions. The Sol variant excels at deep reasoning. Weaknesses: Higher token cost (premium multiplier). Best for: Enterprise applications, microservices, complex backends.

Claude Opus 4.8: Best for Code Quality

Strengths: Clean code output, excellent at following instructions, great refactoring. Weaknesses: Can be conservative with experimental approaches. Best for: Production code, API development, code reviews.

Gemini 3.1 Pro: Best for Multi-Modal

Strengths: Understands images/diagrams, great for UI work, strong at data analysis, large context window. Weaknesses: Newer, less battle-tested for complex backends. Best for: UI/UX implementation, data pipelines, visual debugging.

Our Recommendation

Use Auto mode. It routes each task to the optimal model automatically — cheap models for file reads and simple edits, premium models for architecture and complex reasoning. Or pick manually with transparent multipliers. Multos Elite ($200/month) includes access to all 65+ models across OpenAI, Anthropic, Google, xAI, Mistral, Zhipu, MiniMax, Moonshot, Alibaba, Xiaomi, and more.
