I checked five LLM cost calculators against the published rates

Two of five price Claude Opus at 3x the real rate. All five miss the tokenizer change that makes their token counts about 30% low on current Claude models.

Your token counter may be reading your prompt

One popular token counter posts your text to its server on every keystroke. Another promises no tracking while loading an analytics script. Here is how to check for yourself.

A price rise in four weeks, cache writes charged above input rate, stacking multipliers, and a tokenizer change that quietly invalidates every character-based estimate.

Breaches and Incidents21 Jul 2026

Ransomware playbooks keep failing at the same step: recovery

Ransom demands are collapsing and backups are working. Average recovery cost still rose 11% to $1.7m, and JLR lost five weeks of production for a modelled £1.9bn. The money moved from the ransom to the restore.

Agentic browsers widen the prompt injection attack surface

Brave broke Perplexity Comet twice after it was declared fixed, then repeated the attack against three more agents. The vendors are not losing a patching race; the architecture composes trusted instructions with untrusted content in one context window.

Half of breaches now involve a third party. Every clock starts too late

A 72-hour clause is not a control, it is an accounting mechanism. The clock starts at the vendor's awareness, which is the one variable your contract cannot set.

Credentials did not stop mattering. The DBIR headline was read wrong

Initial access changed. The attack path did not. Half of ransomware victims with a credential leak saw it within 95 days of the attack, a window long enough to act in, if anyone is looking.

The AI Act deadline landed on Sunday. Most people watched the wrong half

High-risk slipped sixteen months. Article 50 transparency did not move an inch and applied from Sunday. The obligation that actually landed is the one that got no attention.

Model context protocols are quietly extending the enterprise perimeter

A poisoned tool description is a prompt injection that ships once and fires on every invocation, for every user, in every session. It is the same root cause as the browser attacks, with persistence added.

58% of executives have had an AI incident. Nearly all are confident

Executive confidence in AI use is not correlated with anything measured. The organisations that had an incident and the ones that feel fine are largely the same organisations, because neither has an inventory.
