A developer's analysis of published rate sheets shows effective costs can jump 10x to 50x depending on model choice, with Opus-class models becoming roughly 27x more expensive under the new system.", "body_md": "Three months ago, almost every AI coding tool had the same deal: pay a flat monthly fee, use it until you hit a wall. That era is over. On June 1, 2026, GitHub flipped Copilot from counting requests to metering tokens, and the reaction was immediate and ugly. The GitHub community discussion announcing the change has 24 thumbs up and 958 thumbs down. Some developers reported their effective costs jumping 10x to 50x overnight because of which model they had selected.\n\nMeanwhile Claude Code never left the flat-rate model. It just quietly throttles you instead: a five-hour rolling usage window, a weekly cap, and since March, reduced limits during weekday peak hours.\n\nSo which billing model actually costs you less? I spent an evening with GitHub's published rate sheets, Anthropic's plan limits, and the third-party calculators that have emerged to track both. Before we start, one disclosure: I run my own AI agent infrastructure on a rented VPS and pay per token through APIs, so I have lived with metered AI billing for two years. I have not personally subscribed to Copilot's new credit system. Every number below comes from primary sources and published rate cards, linked so you can check me.\n\nThe new unit is the GitHub AI Credit, and the conversion is simple: **one credit equals $0.01 of metered model usage**. Every chat message, agent task, and code review now consumes tokens, the tokens are priced at each model's published API rate, and the dollar total converts to credits drawn from your monthly pool.\n\nWhat each plan includes is where sources differ slightly, because GitHub structures it as a base plus a flex allotment:\n\nThree details matter more than the headline numbers:\n\n**Completions are still free.** Inline code completions and Next Edit suggestions remain unlimited on paid plans and never touch credits. If Copilot is mostly autocomplete for you, nothing changed.\n\n**The model choice is the bill.** Twenty-plus models live in the Copilot catalog, and their rates vary enormously. Claude Sonnet 4.6 runs $3 per million input tokens and $15 per million output. Opus-class models run $5 and $25. Some lightweight models, like GPT-5 mini, are included at zero credits. One community user calculated that Opus went from affordable to roughly 27x more expensive under the new math, enough for about 140 Opus requests a month from a Pro+ allowance.\n\n**Overage just runs a tab.** The old system cut you off when you hit your request cap. The new one keeps going and bills the excess at $0.01 per credit. Predictable ceiling, gone. In its place, a variable bill that depends on your model discipline.\n\nAnd starting September 1, code review consumes GitHub Actions minutes on top of AI Credits, a detail buried in the community manager's announcement that teams will feel in two places on the same invoice.\n\nClaude Code takes the opposite bet: a flat subscription with a rationing system rather than a meter.\n\nWhen you hit the wall, you wait. The window resets on a rolling five-hour cycle, and the weekly cap resets Monday. No overage, no surprise invoice, but also no guarantee you can finish your task today. Anthropic has also reduced five-hour limits during weekday peak hours, 5 AM to 11 AM Pacific, since March 2026, which stings if you are a heavy user in a timezone that overlaps US mornings.\n\nThe philosophical difference is real. Copilot prices your usage and lets you work unlimited. Claude Code caps your usage and prices you nothing extra. One behaves like a cloud provider, the other like a gym membership.\n\nPlan tables hide the decision, so let me price an actual unit of work. Say a typical agentic session: the model reads your repo context, plans, and writes a change. Tracked breakdowns of Copilot billing put a realistic Sonnet 4.6 agent session at around 50,000 input tokens and 20,000 output tokens.\n\nAt Sonnet 4.6 rates, that is $0.15 of input plus $0.30 of output, so **$0.45 per session, about 45 credits**. Notice that output is only 40 percent of the tokens but 60 percent of the cost, because output tokens cost 5x input on Anthropic models. That ratio drives everything.\n\nNow the same user on Claude Code. Thirty agent sessions a month is roughly one or two solid working sessions a day. Claude Pro at $20 would plausibly survive that, if the sessions are not enormous, but one deep afternoon of agent work can eat the five-hour window and put you into cooldown. Max 5x at $100 removes the anxiety entirely.\n\nSo the crossover is somewhere around daily agent usage. Below it, Copilot's meter is cheaper because you simply spend less than the subscription price. Above it, Claude's flat rate wins because the marginal session costs zero, up to the throttle.\n\nI reduced this to four working styles, and each has a clear winner:\n\nMy own setup is the third path nobody markets: no subscription at all, just an API key, a small pre-funded balance, and a personal rule that any task over a few cents of output tokens has to justify itself first. Metered billing disciplined me years before GitHub made it mandatory. But that only works because my usage is spiky and I write the harness myself. For most working developers, Copilot Pro plus model discipline is the cheapest sane default in 2026, and Claude Max is worth it the day you catch yourself waiting on a cooldown instead of shipping.\n\nThe deeper shift is worth naming. AI coding tools have moved from subscription economics to cloud economics: metered units, tiered rates, promo windows, step-downs. The developers who thrive in that world are the ones who read the rate card. You are now the person who reads the rate card.\n\nI write about AI tooling, engineering economics, and building with agents every week. Subscribe, it is free, and it helps me keep doing the unglamorous math so you do not have to.\n\nHave you felt the June 1 change in your Copilot bill, or hit a Claude Code cooldown at the worst moment?
