Google Quietly Updated Deep Research — Max Version Incoming
New model IDs spotted: deep-research-max-preview-04-2026 scores 93.3% on DeepSearchQA and 54.6% on HLE.
Two new model strings just leaked into Google's API ecosystem: deep-research-preview-04-2026 and deep-research-max-preview-04-2026 — confirming an April refresh to Gemini's research agent lineup.
Deep Research Max is the heavy-hitter: extended test-time compute, exhaustive web + proprietary source coverage, and async workflows built for overnight deep-dives. Benchmarks put it at 93.3% on DeepSearchQA and 54.6% on Humanity's Last Exam — a meaningful jump. The standard tier trades some depth for speed, making it viable for real-time use cases.
Both agents are now accessible via the Gemini API on paid tiers, letting devs trigger full research workflows with a single call.
Why it matters: Google is quietly turning research agents into infrastructure — the 'Max' naming tier signals a product line, not a one-off. Expect this to compete directly with OpenAI's Deep Research.
