Perplexity is an AI-powered answer engine combining a chatbot with real-time web search to produce cited, synthesized answers to queries.
No evidence-backed relationships are recorded.
Amazon is blocking Meta's Muse agent with a Conditions of Use popup and a bot wall, ten days after the Ninth Circuit refused to rehear its Perplexity case. Agent builders now have to plan for stores that refuse entry through their own terms, whatever the user asked for.
Reality
Pi shipped MCP in v0.99.0 using a sandbox that keeps tool schemas out of context, where three servers took 143,000 of Perplexity's 200,000 tokens. Other harnesses can copy the design if they are willing to host an interpreter that runs model-written code.
Reality
Earendil's Pi 1.0 coding agent ships native MCP support after more than a year of criticising the protocol, running tool calls inside a WASM sandbox. The team credits a more stateless July 2026 spec and a sandbox it already needed for non-LLM models, so MCP support was a small addition.
Reality
Pi made MCP a core feature in version 0.99.0 on September 29, 2026, after its creator Mario Zechner spent over a year arguing against the protocol. In Pi, models call MCP tools from JavaScript in a QuickJS sandbox, so tool schemas are not preloaded into context.

Crusoe confirmed on September 28 that Google is the end user of its Goodnight campus near Amarillo, a site wired to two 265.5MW wind farms. The deal takes Crusoe's power-first model past Abilene, with the same customer whose request halted a 2.7GW Crusoe build in Wyoming in June.
Reality
Shopify's three official AI connectors can change products, inventory and discount codes, while refunds, order edits and the live theme stay in the admin. On a live store, the open question is how many unstaged writes one request can carry.
Reality
Google is contesting two July 16 EU orders that would give ChatGPT, Claude and Perplexity Gemini's system-level access on about 60% of EU smartphones. The duty that matters most for voice, letting rival wake words run alongside Google's, is not due until August 2028.
Reality
Misha, who works on Gobare, found in public docs that OpenAI may delete a sandbox idle for an hour and Gobare pauses one after five minutes. Perplexity promises nothing between responses, so jobs that wait on a human or serve a preview have to fit one of those clocks.
Reality
Named investors told Fortune that 10 to 20 percent of their portfolios now sit in a vulnerable bucket beyond normal mortality, and that only licenses and hard data look insulated.
Reality
A Connecticut school of about 400 students sets AI permission assignment by assignment. The bill for that lands on whoever designed the assignment.
Reality
Keenable left stealth with $26 million and says AI labs already query its index during training and at runtime. The scarcity argument comes from the investor who led the round.
Reality
Portable Computer's harness is real engineering. The bill of materials starts at a $4,800 DGX Spark or a 24GB RTX card, which turns local agents into a hardware order.

Perplexity moved its search serving tier from DynamoDB to CobbleDB, an in-house Rust store, and cut median batch reads from 31.4ms to 5.60ms. The cost case carries to other retrieval teams only at similar payload sizes and request rates.
Reality
Gal Weizman showed that one malicious extension can take over the AI agents in Chrome, Comet, Edge, Neon and Claude in Chrome, with bounties from all five vendors to show for it. Installation is the only precondition.

Amazon has cut Meta's Muse off from shopping its store, using the Conditions of Use its own customers accepted. Anyone shipping a buy-on-behalf feature inherits the merchant consent problem that comes with it.

Meta's Muse passed ChatGPT on Apple's US free chart with roughly 730,000 installs in its first five days. The stock has added more than a fifth of its value since details of the agent emerged.

Britain's competition regulator has strengthened proposals that would put ChatGPT and Perplexity on Android and Chrome choice screens at setup and once a year after, with a final decision due by the end of 2026.
Reality
Perplexity retires its Sonar API on September 27, a date posted in its blog and docs banner but absent from the changelog its FAQ says to watch. Appsmith's managed AI plugin shuts down three days later, on September 30, with no transfer path for uploaded files.
Reality
ChatGPT, Gemini and Perplexity recommended fintechs 1,345 times and banks 452 in 2,160 chats with researchers posing as small-business owners. Because the final prompt asked how to open an account, banks that still require a branch visit face a gap that tagging their websites may not close.
Reality
Amazon kept Meta's Muse out of its cart with a line in its own terms of service. Investors are already pricing which other intermediaries could say the same thing to an agent.
