Anthropic released Claude Review for Claude Code, a new code-review solution that uses parallel agents to hunt for bugs and issues.

"Agents search for bugs in parallel, verify each bug to reduce false positives, and rank bugs by severity. You get one high-signal summary comment plus inline flags."

In general, I expect that in 2026 we will see a rise of "parallelization", which will also significantly bump average token consumption. Models will get cheaper, but we will start consuming them more and more.
