## Summary

TinyFish released two technical guides that detail a production‑grade agentic search architecture and lessons from building a deep research system. The architecture relies on four web primitives – TinySearch, TinyFetch, TinyBrowser and TinyAgent – and runs a seven‑phase control loop that separates model reasoning from deterministic tool execution. On OpenBenchmarks the system achieved a 79.0% completion rate on coding tasks while costing a median $0.050 per task and using the smallest token footprint among tested providers.

Across seven QA datasets the multi‑turn search component beat RAG baselines by 41% with Qwen2.5‑7B and 20% with Qwen2.5‑3B. In a search‑only benchmark TinyFish completed 59.3% of tasks, compared with 77.3% for Perplexity, 70.3% for Firecrawl and 66.3% for Exa Fast. Engineering changes such as merging planning into the orchestrator, removing sub‑agents, and ranking sources by research objective reduced latency by up to 5x and increased throughput by up to 3.4x. The guides also outline failure‑aware retries, evidence contracts, and strict caps on tokens, time and cost.

## Key points

- 79.0% coding task completion with median $0.050 task cost on OpenBenchmarks
- Search‑only completion 59.3% vs 77.3% Perplexity, 70.3% Firecrawl, 66.3% Exa Fast
- Multi‑turn search improves over RAG baselines by 41% (Qwen2.5‑7B) and 20% (Qwen2.5‑3B)

## Why it matters

The architecture shows how to build reliable, cost‑effective AI agents for production, addressing common retrieval failures and reducing latency and expense.
