Perplexity Open-Sources SPACE Agent Sandbox; Senate Panel Advances TAS Act; Grok Bot Adds Connectors

Perplexity open-sourced SPACE, the agent sandbox platform behind Computer, giving developers control over where agents run code and what resources they can access.
The Senate Finance Committee advanced the TAS Act 26-1, setting IRS refund deadlines, e-filing rules, and a unified January 31 deadline for 1099 filings.
Grok Bot updates include 3x faster computer tasks, halved response times, X chat integration, and new Robinhood and Coinbase connectors.
Musk said Optimus and Cybercab will account for most of Tesla's value, while Starlink cases span Papua New Guinea clinics and Southwest's 47 equipped aircraft.
A scriptc benchmark claiming a 1.6x speedup over bun --aot was flagged by its own sharer as untrustworthy because it tested no real applications.
Paul Graham argued paywalled content becomes effectively invisible if AI cannot find it, and noted a preprint reporting pig kidneys recovered after up to a year at −150°C.

Perplexity open-sourced SPACE, described as the agent sandbox platform supporting Computer, so developers can better control where agents execute code and which resources they can reach; the company said safer agents cannot rely on model-level safeguards alone 1. Perplexity also said Computer produced a cyberpunk-style Roadster free-roaming browser game 2.
Grok Bot drew user reports of completing price comparisons, orders, and refunds, and of building a new business that generated $700 in revenue; Musk said the team makes about 20 improvements per day 1 2 3 4 5. A shared update list cited 3x faster computer tasks, halved reply times, X chat message integration, and new connectors including Robinhood and Coinbase 6. Jason Fried endorsed connecting a Grok bot to Basecamp 7.
A benchmark shared by Guillermo Rauch claimed scriptc was 1.6x faster than bun --aot, but the post explicitly warned the result should not be trusted because the benchmark was specifically optimized for scriptc and tested neither the user's own application nor any real application 1. Rauch separately endorsed the view that the final product, whether a game or an engine, is what matters 2.

The Senate Finance Committee advanced the Taxpayer Assistance and Service Act (TAS Act) by a 26-1 bipartisan vote. Under the forwarded description, the bill would require the IRS to rule on refund claims within 12 months, fully digitize tax-form processing and use OCR on paper mail, treat e-filed returns received by the IRS within three business days of the deadline as timely, upgrade online accounts, publish real-time dashboards for call volume, backlogs, and wait times, and let tax practitioners access client accounts without logging in for each one 1. The same forwarded material said the bill would move the 1099-series information-return deadline to January 31, eliminating the current March 31 e-filing date, and that NATP wrote to Chairman Mike Crapo and ranking member Ron Wyden on September 15, 2026, with CEO Scott Artman saying the vote showed taxpayer service and reasonable standards for paid preparers are not partisan goals 2.
Sahil Lavingia said this would be a golden age of government software, while also sharing a qualified view: apps that perform badly only because no one scheduled six weeks of engineering time can fit that label, but for apps failing due to difficult policy decisions, a new interface has limited effect 1 2.

Musk said the future Roadster demonstration will include flying over the Snake River or the Grand Canyon, landing on its wheels, and exceeding half the speed of sound, calling it an inevitable, ironic twist of fate that the Roadster becomes a flying car 1 2. A shared comparison claimed the new Roadster's cold-gas thrusters exceed 80 kN, above the roughly 79.2 kN of an F-16 without afterburner 3. Musk also said Optimus and Cybercab will account for the vast majority of Tesla's value, and that superintelligence, robots, solar power, and large-scale orbital access are the only directions that can economically scale to extreme size 4.
Starlink-related shares included four health centers in Morobe Province, Papua New Guinea, receiving equipment with three already installed and plans to extend to 54 facilities, and a sailor in a remote Indonesian lagoon who had a stroke with no cell signal and was rescued after contacting help via Starlink 1 2. Southwest Airlines has 47 aircraft equipped with Starlink and plans fleet-wide coverage by fall 2027 3. Musk shared that Falcon 9's Bandwagon-5 rideshare mission has encapsulated 32 payloads for launch from Florida 4.

Paul Graham argued that publishing on a paywalled site amounts to making content invisible: if AI cannot find it, it effectively does not exist, though he acknowledged the claim is not yet fully true and will become more so 1. He also shared a preprint reporting that human-scale pig kidneys vitrified and stored at −150°C for up to one year recovered function, showing vascular, metabolic, and excretory activity and producing urine after transplant, which the post framed as a significant advance for organ cryopreservation and organ banking 2.
Musk said 𝕏 usage hit an all-time high, citing Similarweb data of 13.43 billion visits in Q3 2026, up 6% quarter over quarter and 760 million visits 1. He also shared a claim that Anthropic signed a $15 billion compute agreement with SpaceX and that xAI launched Grokipedia overnight with 6 million entries; these figures come from a forwarded post and are disputed/unverified 2.
Garry Tan shared that GLM 5.3 Flash is now free in OpenCode 1, and described TSK-Bench, an AI task leaderboard testing top models on building apps, connecting agents, and running automation, with Taskade planning bring-your-own-key support 2. Alexis Ohanian endorsed the view that games long wanted but too costly to make, and games developers could not build due to resource limits, will soon become possible, calling it a new golden age for games 3.
