Walmart put a token allowance on its in-house coding AI News
Walmart replaced unlimited access to its in-house AI coding tool with a fixed per-employee token allotment, and its CTO says the reason is duplicated requests rather than the bill.
A $500 fine-tune of a 9B open model beat all five frontier models it was tested against News
A consultancy reinforcement-trained a 9-billion-parameter open model on a simulated product-catalog review workflow for about $500 of GPU time, and it outscored the best of five frontier configurations while costing $0.50 per thousand listings against $34.
Someone put a wiretap on two coding agents. One sends five times more before you type a word. News
An applied-research firm metered the traffic of two AI coding agents and found Claude Code sends about 33,000 tokens of fixed overhead before your prompt arrives, versus about 7,000 for OpenCode.
Prompt Caching: Why AI Agents Pay Once to Read, Then Read for Pennies Lesson
Prompt caching lets an AI provider store the processed form of a repeated chunk of text -- like a long system prompt -- so it can be reused across requests at a fraction of the cost, instead of being re-processed every time.
Meta caps employee AI token use after a 'Claudeonomics' leaderboard drove costs toward billions News
Meta imposed centralized quotas on employee AI usage after staff burned an estimated 73.7 trillion tokens in about a month, gamifying consumption on an internal leaderboard, with costs projected to reach billions in 2026.
Caveman Tool
A skill that compresses AI agent responses into terse output, cutting roughly 65% of output tokens while preserving technical accuracy across 30-plus coding agents like Claude Code, Cursor, and Gemini.
