~1 min readPangram has released Pangram 4, a new model for detecting AI-generated text. The model is six times larger than its predecessor, with 14 times fewer false positives and six times fewer missed AI texts. In the company's own benchmarks, it correctly identifies 99.66 percent of all AI text and falsely flags human writing just 0.0041 percent of the time, roughly one error per 24,000 documents.

Pangram 4 can also distinguish lightly AI-polished text from fully AI-generated text, the company says. It resists "humanizer" tools that disguise AI writing as human, catching the AI component across 13 common humanizers 98.83 percent of the time.
The API costs $0.05 per 100 words, a two- to tenfold price increase depending on document length. All plans now include image scanning at no extra cost. Pangram 3 stays available until September 30, 2026. Business is booming, according to the New York Times. Annual revenue has grown 35x year over year, and monthly users jumped from 2,700 in June 2025 to 120,000 in June 2026.

An AI model programmed nonstop for 19 days on a single MirrorCode task that cost $2,600 to run
Epoch AI's MirrorCode benchmark reveals Claude Opus 4.7 as the leader with a 56% solve rate, reconstructing a 16,000-line toolkit in 14 hours. Despite this, all models tested struggle with the most complex tasks, highlighting limitations in current AI capabilities. The single task consumed $2,600 over 19 days, raising questions about cost-effectiveness in AI development.
