Claude AI Spends 81 Minutes on 'Real Thinking' – User Report Spikes Around Major Updates

A Reddit user reports that Claude AI recently spent 1 hour and 21 minutes of "real thinking" time on a simple task, producing a good result. The user speculates a recurring pattern: performance seems to spike for the first 1–2 hours after a major update or new feature release, then returns to baseline.

Key Observations

• Last month, the same user created a research thread that successfully scanned 5,113 sources (linked in original post).
• Since then, they have been unable to replicate that level of performance—subsequent attempts scan at most 100–200 sources and yield average results.
• The user hypothesizes that early adopters of new features occasionally get a "mythos-like" boost in reasoning capabilities, which later normalizes.

This anecdotal evidence suggests Claude's "real thinking" mode may be subject to backend variability, possibly due to model caching, allocation of compute resources, or gradual rollout of updates. Developers relying on Claude AI for deep research tasks may need to account for this inconsistency, treating early-access features as a best-effort spike rather than a guaranteed capability.
