Developer commentary on VS Code 1.118 and Copilot billing pressure, focused on token efficiency, caching, and agent workflow changes.
Shows token waste becoming a product-design constraint in everyday developer tooling, not just an abstract FinOps concern.
When billing moves closer to actual token burn, IDEs and agents start optimizing prompts, tools, and context loading as first-class work.
Use as commentary rather than a primary release source; pair it with official GitHub or VS Code notes for exact billing details.

Mahnoor Faisal opened a new Claude Code session, ran /context, and found 51,400 tokens already loaded. Disabling four test plugins and auto-memory got the starting context down to roughly 41,400 before any real prompt.
At Splunk .conf on Sept. 15, Cisco added a Tokenomics module to Splunk Agent Observability. It attributes token spend across AI agents and across employees' use of coding agents, naming Claude Code, Codex and Cursor.
XDA's Mahnoor Faisal ran five coding jobs on Sonnet 5 twice from an identical starting codebase, changing only the effort level. High spent about 26,000 output tokens; Medium finished the same work on roughly 14,300.
