The Verdict
Claude Haiku 4.5 crushes on price. GPT-5.6 Sol dominates on context and raw capability.
Claude Haiku 4.5 ($1/$5) is dramatically cheaper than GPT-5.6 Sol ($5/$30) — 80% less on input, 83% less on output. For most production workloads (chatbots, classification, summarization), Haiku 4.5 delivers excellent performance at a fraction of the cost. GPT-5.6 Sol only makes sense if you need the 1.05M context window (5x larger than Haiku's 200K) or the absolute latest reasoning capabilities.
When to Choose Claude Haiku 4.5
- High-volume production: At $1/$5, Haiku 4.5 handles massive request volumes at minimal cost. For 10,000+ requests/day, the savings vs Sol are enormous.
- Simple-to-moderate tasks: Classification, summarization, Q&A, data extraction — Haiku 4.5 handles these well at 82% less cost.
- Startup MVPs: If you're building an AI startup and need to stretch your budget, Haiku 4.5 gives you 5.6x the requests for the same spend.
- Edge deployment: Haiku 4.5's smaller context window and lower cost make it ideal for mobile and edge AI applications.
When to Choose GPT-5.6 Sol
- Massive context needs: The 1.05M context window is 5.25x larger than Haiku's 200K. If you need to process entire codebases or 500K+ token documents, Sol is the clear choice.
- Complex reasoning: GPT-5.6 is OpenAI's latest flagship — for the most demanding reasoning tasks, Sol may have an edge. Test both for your specific use case.
- Mixed workloads: If your tasks vary from simple to very complex, and you can't route to different models, Sol's versatility may justify the premium.
