- What changed
- An evaluation of coding models on 904 software engineering tasks shows that Anthropic's Claude Fable 5 leads in single-attempt accuracy at roughly ninety times the cost of DeepSeek V4 Pro 0813, while the DeepSeek model wins on multi-attempt success and routing strategies.
- Why you should care
- Engineering leaders can significantly cut software development tool budgets by routing routine programming tasks to cheaper models without sacrificing final success rates when multiple attempts are allowed.
- Your move
- Watch. Test a multi-model routing strategy in your software development workflows, sending simpler coding requests to lower-cost models first and escalating only when needed to optimize API budgets.
- What to watch next
- Watch for further verified reporting or independent evidence.
