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.

LiteRT-LM is Google's production-grade, open-source inference framework for deploying Large Language Models on edge devices — phones, IoT hardware, Raspberry Pi, and desktop machines without cloud connectivity. Launched April 7, 2026 alongside Gemma 4 support, it enables developers to run Gemma, Llama, Phi-4, Qwen, and other models entirely locally via a simple CLI or embedded SDK. The framework handles the hard parts of edge inference: memory-mapped per-layer embeddings, 2-bit and 4-bit quantization, NPU acceleration for Qualcomm and MediaTek chipsets (early access), and cross-platform support spanning Android, iOS, Web, and desktop. Gemma 4's E2B variant runs under 1.5GB RAM on some devices, making full LLM functionality viable on mid-range hardware. What makes LiteRT-LM significant is the agentic angle. It's one of the first frameworks to support multi-step agentic workflows running completely on-device — function calling, tool use, vision and audio inputs — without a single network request. For developers building privacy-sensitive apps or offline-capable agents, this changes the calculus entirely.
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.”
“This is the real deal for edge AI development. The CLI makes it trivial to get Gemma 4 running locally in minutes, and function calling support means you can build actual agentic apps that work offline. Google backing means this won't be abandoned in six months.”
“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.”
“NPU acceleration is still early access and the model selection is Google-heavy. Developers building with Llama or Mistral have Ollama and llama.cpp with far more mature ecosystems. LiteRT-LM needs a year of community baking before it rivals those alternatives.”
“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.”
“On-device agentic AI is the privacy-preserving future of personal computing. LiteRT-LM gives Google a strong position in edge inference infrastructure — expect this to become the default runtime for Android AI features within 18 months.”
“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.”
“The vision and audio input support unlocks real creative tools that work on a plane or in a studio without WiFi. Running a multimodal model locally with no usage fees means I can experiment with AI-assisted workflows without watching a billing meter.”
