Deep Research
researchweb-searchdeep-researchsummarizationfact-finding
Iterative web-research agent. Takes a free-text research query and produces a structured report: 3-8 sentence summary, 3-10 self-contained key findings, ranked grounded sources, confidence rating, and notes on what was uncertain. Generates sub-queries, runs grounded Google Search, reflects on gaps, and iterates. Runs at three depths (quick / standard / thorough) which cap total search calls. Uses Gemini 3.5 Flash with native Google Search grounding. Supports one round of human-in-the-loop clarification on turn 1 if the query is genuinely ambiguous — emits status='needs_input' with a single clarifying question; on the next call, include the user's answer in payload.clarifications and the agent proceeds straight to research.
Example input
{
"query": "What's the current state of solid-state battery commercialization for EVs in 2026, who's leading, and what are the remaining blockers?",
"depth": "standard"
}
Example output
{
"status": "ok",
"summary": "As of mid-2026, solid-state batteries (SSBs) have moved from lab demos to limited pilot production, but mass-market EV adoption is still 2-3 years out. Toyota, QuantumScape, and Samsung SDI lead with 2027-2028 commercial timelines for first-gen SSBs in premium vehicles. Manufacturing yield and dendrite suppression remain the two biggest blockers. Cell-level energy density has reached ~400 Wh/kg in pilot lines, ~30% above current Li-ion. Pilot cost is roughly 3x current LFP; parity is expected near 2030.",
"key_findings": [
"Toyota plans its first commercial SSB-equipped EV in 2027, starting with a smaller battery in a hybrid before scaling to BEVs.",
"QuantumScape began first commercial shipments to PowerCo (the VW JV) in late 2025; pilot vehicles are running in 2026.",
"Sulfide-based SSB cells reached ~400 Wh/kg at the cell level in 2025, roughly 30% above current Li-ion benchmarks.",
"Pilot-line cost is ~$200/kWh vs ~$80/kWh for current LFP; the path to $100/kWh depends on manufacturing scale rather than chemistry.",
"Dendrite formation at the lithium-metal anode remains the dominant failure mode beyond ~1000 cycles in published cycling tests."
