Tiered Model Routing Cuts Claude API Costs
A developer-author describes a four-tier model-routing architecture to reduce costly use of Anthropic’s Claude Sonnet in autonomous Claude Code agents. The system routes tasks to the cheapest capable model: Tier 0 uses local Ollama inference (qwen2.5:7b) for classification, extraction and summarization; Tier 1 uses Claude Haiku for reliable structured outputs; Tier 2 reserves Claude Sonnet for multi-step reasoning, code, and synthesis; Tier 3 uses Claude Opus only for irreversible, highest-stakes actions. The article includes a decision tree, example routing code, Ollama setup steps, instrumentation advice, and a day-in-the-life cost comparison showing roughly a 95% reduction in API token usage for background tasks. The author packages the routing configuration as a skill on ClawMart.
Anthropic Claude Opus 5: Cheaper, Better Code
Anthropic released Claude Opus 5, a new model the author found ~33% cheaper than Opus 4 and improved for production-focused code generation and tool calling. In hands-on tests for a cross-border e-commerce workflow, Opus 5 produced cleaner multi-file FastAPI scaffolding (including TTL-based caching and type hints), showed ~15–20% higher code accuracy, and delivered ~20–25% better multi-step/tool orchestration reliability versus Opus 4. The author also observed improved tool-calling behavior (more consistent parameter extraction and more frequent retries on tool errors). Cost reductions (input: $15/M → $10/M tokens; output: $75/M → $50/M tokens) make additional automation steps economically viable for high-volume pipelines. The article concludes that the combination of lower cost and increased reliability shifts trade-offs toward broader automation in production pipelines.
Auto Router: 45% Lower Cost on 25 SWE-bench Tasks
We solved 23 of 25 SWE-bench Verified tasks with LiteLLM's experimental capability router for $11.15, compared with $20.27 using Opus 5.
