Sample from this week
Two lines crossed this week. GitHub Copilot's flat-fee safety net is gone. Anthropic filed to go public at $965B — confirming the promotional era of AI is over and companies need profit, not just product-market fit.
GitHub replaced Copilot's flat subscription with token-based billing June 1, killing the safety net that downgraded users to cheaper models when premium requests ran out. Code completions remain free, but chat sessions and autonomous coding now burn AI Credits at published API rates.
→ Budget your agent use now or get budget-shocked by July's bill. Set a monthly credit cap in GitHub settings before running another autonomous session.
"The only newsletter that tells me what a pricing change actually means for my API costs. Every other one just reports the headline."
