TinyFish

AI startup TinyFish has released two engineering research articles on agentic search, the technology that lets AI agents retrieve and verify information autonomously. One piece lays out a seven-phase production architecture featuring evidence contracts and bounded retries, while the other explains the reasoning behind its deep research approach, offering rare implementation detail for teams building production AI agents.

TinyFish has removed search fees for AI agents, renewing debate over what it actually costs an agent to read the web. Industry commentary points to two expenses: the retrieval charge that search and fetch APIs bill per request, and the model processing cost of handling the content those queries return. Making search free shifts attention to processing, often the larger bill.
