Anthropic executives later confirmed they had quietly changed the default reasoning ‘effort’ level from ‘High’ to ‘Medium’ to improve speed and reduce token costs… bugs in the prompt-caching system that reportedly inflated user costs by 10–20x

Anthropic engineering post-mortem (April 23, 2026) anthropic.com

An experimental system prompt instructing the model to keep text between tool calls to ≤25 words and final responses to ≤100 words ‘hurt coding quality’ and was fully reverted on April 20, 2026.

Finout — ‘The real cost story behind the unchanged price tag’ finout.io

The new tokenizer produces 1.0–1.35x more tokens for the same raw text, amounting to an effectively silent ~35% price increase on code, SQL and JSON workloads despite the unchanged $5/$25 rate card.

Setting temperature, top_p or top_k to non-default values now returns a 400 error; analysts read the forced temperature=1.0 as a ‘distillation defense’ to poison outputs against rival labs distilling Claude.

Help Net Security — Claude Opus 4.7 released helpnetsecurity.com

Anthropic withheld the more capable ‘Claude Mythos Preview’ from public release because it can autonomously chain zero-day exploits, restricting it to ~50 Project Glasswing partners (Microsoft, Apple, AWS) — a ‘club-based’ access model critics call structurally inequitable.

Independent testers report a regression on MRCR v2 long-context recall from 78.3% (Opus 4.6) to 32.2% (Opus 4.7), and call Anthropic’s headline benchmark gains ‘leaderboard theater’ next to real-world flakiness.

Medium (creed_1732) — ‘98% Accuracy: What It Actually Means’ medium.com

The staggering jump from 23% to 98% comes entirely from internal DeepMind benchmarks; reflective glass, shadows and oblique viewing angles in real plants are not represented in the eval set.

In a flagship demo, Spot read a handwritten to-do list off a chalkboard, sorted shoes, checked mousetraps, and even took a real dog on a leash for a walk and a game of fetch.
