Perplexity AI
Perplexity AI is an answer engine that runs live web searches and returns cited answers, with Deep Research for long agentic reports, Spaces for persistent projects, the Comet browser, and the Sonar API for developers.
- Citations make answers checkable in seconds rather than on trust
- Deep Research replaces hours of manual comparison work
- Spaces keep long-running research context instead of losing it per chat
- Genuinely useful free tier, not just a teaser
- Cites whatever ranks, so weak sources can look authoritative
- Summaries occasionally overstate what the linked page actually says
- Live search can amplify a recent error before corrections circulate
Reka
Reka is an AI research lab building omni models — Spark, Edge, Flash and Core — that process video, image, audio and text in a single architecture rather than bolting modalities together. It also runs Reka Cloud for training and deployment, video infrastructure available by API or MCP, and a training-data division.
- Native multimodality preserves timing and co-occurrence that captioning pipelines discard
- A model range including an edge option matches what robotics and sensing actually require
- Video search over large archives addresses a genuinely unsolved organisational problem
- MCP support means AI agents can query the video layer without a bespoke integration
- No context lengths, benchmarks or evaluation results are published anywhere on the site
- No pricing exists in public, so cost cannot be assessed without a sales conversation
- No position is stated on open weights or self-hosting, which edge buyers will ask about first
