Google opened its Deep Research and Deep Research Max agents to developers via the Gemini API, running on Gemini 3.1 Pro. These are the same autonomous research agents that power the consumer Gemini experience — now available as API primitives you can embed in your own apps, dashboards, or agentic workflows. Deep Research Max is benchmarked at 93.3% on DeepSearchQA, a record for autonomous research. The April 2026 API launch adds capabilities beyond the consumer product: MCP server support for connecting to private data and professional streams (FactSet, S&P Global, and PitchBook integrations are already live), native chart and infographic generation inline with research output, and the ability to mix sources simultaneously — web search, uploaded PDFs/CSVs/video/audio, and URL context. Code Execution and File Search also run alongside web grounding in a single call. For developers building research-heavy apps — competitive intelligence, financial analysis, legal research, scientific literature review — this is a meaningful unlock. Rather than chaining together search, retrieval, synthesis, and visualization layers yourself, the Deep Research API handles the full multi-hop research loop. Pricing and rate limits at enterprise scale remain the key question.

MinerU2.5 is a 1.2-billion parameter vision-language model purpose-built for high-resolution document parsing. From OpenDataLab, it's the latest version of a project that's accumulated 61.5K GitHub stars — which tells you something about how painful document-to-text has been as a category. The model uses a decoupled vision-language architecture for efficient high-resolution processing with state-of-the-art recognition accuracy across tables, formulas, figures, and mixed-layout documents. The core use case is turning messy PDFs, scanned forms, academic papers, and enterprise documents into clean Markdown or structured JSON that LLMs can actually work with. Earlier MinerU versions were already widely adopted for RAG pipeline preprocessing — 2.5 tightens up accuracy on the edge cases that killed earlier tools: rotated pages, dense tables, multi-column layouts, and multilingual content. At 1.2B parameters it's lightweight enough to run locally without a GPU farm, and the Apache 2.0 license means it integrates cleanly into commercial document pipelines. For anyone building RAG applications, AI research assistants, or document intelligence products, this is the preprocessing layer that removes a persistent pain point.
Reviewer scorecard
“The MCP integration is the real story — connecting Deep Research to our internal data warehouse with a single server definition and getting research-grade synthesis in return is exactly what enterprise AI apps need. This replaces three separate pipeline stages for us.”
“I've tried six document parsing libraries and MinerU has the best table extraction accuracy I've seen at any price point. The Markdown output is clean enough to feed directly into embedding pipelines without post-processing. 61K stars isn't hype — it's earned.”
“93.3% on DeepSearchQA sounds great until you hit domain-specific queries where benchmark performance rarely holds. With Google controlling the search layer, there are legitimate questions about source diversity and SEO-optimized results contaminating research quality.”
“It's good, but 'state-of-the-art' in document parsing has a long history of being true until you hit your company's specific document formats. Complex form PDFs with non-standard layouts will still break it. And at 1.2B parameters, it's not actually that lightweight on CPU-only hardware.”
“When every developer app embeds a research agent that simultaneously queries the live web and private data, the gap between Bloomberg Terminal-quality research and a startup's internal tool effectively collapses.”
“Document parsing is the unsexy infrastructure that every enterprise AI project depends on. A high-accuracy open-source model at this scale removes one more reason for organizations to stay locked into expensive cloud document APIs. This is how AI democratization actually happens.”
“Native chart generation inside research output is the killer feature — I can hand a client a report with visualizations baked in, not just text summaries. That changes the entire deliverable format for research-heavy creative work.”
“Research assistants and knowledge bases live or die on document ingestion quality. MinerU2.5 handling formulas, multi-column layouts, and mixed media means I can finally build reliable pipelines from academic PDFs without babysitting the output.”
