Show HN: Reka Research – A SOTA research agent

https://reka.ai/products/research
6•donovanOng•4h ago
Hi HN,

We built something new! It is an AI agent that can:

- iterate through up to a dozen sources (web or GDrive)

- reason between hops in natural language (exposed in the trace)

- generate structured JSON so downstream code can consume results deterministically

It not only delivers state-of-the-art performance on both SimpleQA and Reka Research-Eval, but also shatters the notion that cutting-edge AI must come at a premium, being significantly more affordable than alternatives.

Tech stack highlights

- Base model: Reka Flash 3.1 (trained from scratch, post-trained with RL on verifiable rewards)

- Flat pricing: $0.025/query (no extra token usage cost)

- Public REST API (OpenAI-style), plus on-prem / VPC options for enterprises
