Why do autonomous agent tasks in Roo Code consume so many tokens?

Roo Code runs iterative agentic loops: tool execution, shell command output, terminal stderr, and multi-file code reads. In a 30-turn refactoring task, the entire cumulative conversation history (often 80k to 150k tokens) is re-sent on every single turn, multiplying cost exponentially without prompt caching.

How does Newton's pass through prompt caching in Roo Code?

Newton's edge gateway detects cacheable system prompts and repetitive workspace context, retaining prefix cache markers at the upstream provider. Cached tokens are billed at up to a 90% discount (e.g. $0.065/M for Claude Sonnet 5 instead of $0.65/M), and all savings are credited directly back to your balance.

How do I configure Roo Code to use Newton's?

In the Roo Code extension settings, select 'OpenAI Compatible' as your API provider. Set Base URL to https://newtons.dev/api/v1, enter your Newton's API key, and choose your preferred model ID (such as gpt-5.6-sol or claude-sonnet-5).

Roo Code & Cline: Slash Autonomous Agent Costs by Up to 90%

How to configure native prompt caching, eliminate token waste in 50-turn agentic loops, and monitor real-time dollar savings with Newton's edge gateway.

Without Prompt Caching

Every loop turn re-charges 100% of the workspace context, file ASTs, and terminal outputs at full price.

~$14.50 / task

With Newton's Cache Pass-Through

Repeat turns hit cached memory prefixes, discounting input tokens by up to 90% across your entire run.

~$1.85 / task
