Model-Routing

A single developer running Claude Code full-time can burn $3,000-$13,000/month in API costs. A 20-person team using coding agents at the same intensity hits $47K/month before they realize something is wrong. The research across Beam, AgentMarketCap, and Stanford’s Digital Economy Lab points to the same number: 60-70% of that spending is waste — redundant context loading, fat prompts, wrong model choices, and bloated session histories. This guide covers the eight strategies that actually move the needle, ranked by impact, with code and configs you can apply today. ...

Claude Fable 5 cost pricing is premium-model pricing: $10 per million input tokens and $50 per million output tokens, currently best treated as a planning and routing target while access is suspended. Use it only when stronger autonomy, fewer retries, or lower human review time can offset the 2x Opus 4.8 and 10x Haiku 4.5 list price. What is the current status of Claude Fable 5 pricing and availability? Claude Fable 5 pricing is published by Anthropic, but Fable 5 access is suspended as of the June 12, 2026 access update, so cost optimization is currently a design, budgeting, and fallback-routing exercise rather than a live migration plan for most teams. The published rate is $10 per million input tokens and $50 per million output tokens, with prompt-cache hits receiving the existing 90% input-token discount. Anthropic also stated that Fable 5 and Mythos 5 were disabled for all customers after a US government directive affected access for foreign nationals, while other Claude models were not affected. That matters operationally: a production app cannot assume Fable 5 will be callable, even if pricing tables still exist. The practical takeaway is simple: design your routing policy now, but keep Opus 4.8 and Haiku 4.5 as the working production path until Fable 5 availability is restored. ...

The fastest path to cutting your LLM API bill by 70% is stacking five to six optimization levers simultaneously—no single strategy gets you there alone. Model routing alone saves 40–70%. Prompt caching alone saves 50–90% on cached tokens. Combine them with batch processing, semantic caching, and token compression, and the compound effect easily clears 70% total reduction. This guide walks through all ten strategies with concrete implementation steps, real savings numbers, and guidance on sequencing them for maximum impact. ...
