AI Product Updates: New Features and Releases

Perplexity explains how Photon ships new indexes: each is built separately, then switched in group by group, with caches warmed by real queries while the other groups keep serving traffic.

Perplexity says Photon now handles all retrieval and ranking across the product, replacing the open-source engine it used before.

Across six agent benchmarks, Fast Search cut cost per task by 68% versus the default preset at comparable quality, with a 160 ms median latency, the lowest of the search APIs compared.

Perplexity launched Fast Search, built on Photon, its in-house Rust retrieval and ranking service, returning 95% of search results in 230 ms or less.

FAZE released an MCP interface that it says lets AI agents launch and trade stock pair strategies, bringing trading into agent workflows.

LangSmith added end-to-end fine-tuning that uses existing trace data to train specialized models for lower cost and latency, now in public beta.

Users can describe an app in natural language to build creative tools like character studios, 3D viewers and motion effects tailored to their workflow.

Prism, a new product shared by YC, is an inference cloud for open-source LLMs that uses agents to automatically optimize deployment configurations.

Dialo launched on Pumpfun and is open for use: users describe a request in a message, approve the plan, and an agent places the call, returning the result, transcript and recording.

Vellum released Ambient Assistants aimed at solo businesses, able to guide users step by step through interfaces such as QuickBooks and Shopify.

Vellum's Ambient Assistant appears as a floating pill over any Mac app, sees the screen in real time, can circle buttons to point things out, and accepts tasks by voice.

LangChain shares the managed-deepagents 0.8 update, which adds agent and user memory capabilities.
