“companies like Anthropic are ending their all you can eat buffet, which will make many customers think twice.”
Gary Marcus, author 2 June 2026 Why things will eventually fall apart (Marcus on AI)
Companies like Anthropic are ending their all-you-can-eat pricing, which will make many customers think twice.
Mixed Partly true and partly false in roughly equal measure.
What would count as true or false
This is a factual claim judged as of 2026-06-02. The factual core: Anthropic, and possibly similar companies, had by that date announced or carried out the end or curtailment of flat-rate, effectively unlimited ('all-you-can-eat') usage plans, for example by adding usage caps, weekly limits, or metered or usage-based pricing on subscriptions such as Claude Pro/Max or Claude Code. The prediction that 'many customers will think twice' is opinion and is not tested except as a plausible consequence. True: Anthropic's official announcements or credible reports dated on or before 2026-06-02 show such a change, made or announced. Mostly true: the change was announced but only partly in effect, or applied to only some plans, while still clearly curtailing unlimited use. Mixed: Anthropic tightened limits only marginally and the plans stayed largely flat-rate. Mostly false: the cited change was a minor adjustment, or applied only to other companies and not Anthropic. False: Anthropic's pricing pages or announcements as of that date show its unlimited or flat-rate plans unchanged, with no announced curtailment.
Evidence
- Anthropic throttles Claude subscriptions to meet capacity InfoWorld · 27 March 2026
“Anthropic has started limiting usage across its Claude subscriptions to cope with rising demand that is stretching its compute capacity.”
- Anthropic throttles Claude subscriptions to meet capacity InfoWorld · 27 March 2026
“To manage growing demand for Claude we’re adjusting our 5 hour session limits for free/Pro/Max subs during peak hours. Your weekly limits remain unchanged,” Thariq Shihipar, a member of Anthropic’s technical staff, wrote in a post on X.”
- Higher usage limits and a SpaceX compute deal Anthropic · 6 May 2026
“Second, we’re removing the peak hours limit reduction on Claude Code for Pro and Max accounts.”
Reasoning
E1 and E2 show that in March 2026 Anthropic cut the 5-hour session limits for Free, Pro and Max subscriptions during peak hours. They also quote an Anthropic staff member saying weekly limits stayed the same, which suggests the plans already had caps and were not unlimited. In May 2026, E3 shows Anthropic removed the peak-hour limit reduction on Claude Code for Pro and Max accounts, under the heading of higher usage limits. Before 2026-06-02, then, the evidence shows only a limited tightening of peak-hour 5-hour session limits, with weekly limits unchanged [E2], part of which (for Claude Code on Pro and Max accounts) Anthropic later said it was removing [E3]. None of the evidence shows Anthropic ending flat-rate pricing.
