Frontier model scoring 55.8 percent on PerceptionBench.
No evidence-backed relationships are recorded.
JetBrains traced a model through fifteen C# refactoring tasks and found it simulating structure with sed, git and the compiler. Wiring in Rider's real engine cut median time by 83%.
Reality
An independent researcher says the CLI uploaded a repository it was told not to read, plus a .env secrets file, verbatim. That is a procurement question, not a benchmark question.
Reality
A new cost analysis puts OpenAI's frontier model at half Anthropic's price per benchmark task. The retry and cleanup arithmetic behind that number is less settled than the price sheet.
Reality
IBM Research ran self-mined guidelines across eight models on AppWorld. One model gained 16.1 points for 5 percent more tokens; another gained nothing at all.
Reality
Arize and Fireworks ran ten models against 40 agent tasks and found the cheapest model per finished job also had the worst pass rate. Coverage, not price, is the binding constraint.
Reality
A production test across 15 models put seven of them inside a one-point spread on pass rate. On constrained payroll work, the price premium bought speed, not correctness.
Reality
Moonshot AI's new benchmark strips reasoning out of visual tasks. No frontier model cleared 60 percent, which suggests a lot of logged reasoning failures were misreads.
