Just five years ago, finding worthwhile Texas barbecue might have been a challenge in the Bay Area, but now it’s the region’s most popular style. Here are the shining stars of Southern-style barbecue in the Bay Area: sfchronicle.com/projects/best-…

Because of DashBench, we’re able to quickly discern which model combinations yield the best results and at the best cost. For example, with DashBench we’ve seen Kimi K2.6 + Fable 5 vastly outperform our current Sonnet 4.6 + Opus 4.8 harness at a cheaper cost. Having our own benchmark allows us to build confidence in leveraging the frontier intelligence and open-weight models without compromising on enterprise outcomes.

We benchmarked Claude Fable on DashBench PR Review (our internal code-review benchmark) Claude Fable had the strongest overall performance: • 62.7% recall (almost double that of Opus 4.8) • 88.7% precision • 73.4% F1 GPT-5.5 had the highest precision at 91.7%. Also, Fable was ~2.5x more expensive per PR. Code review is one of our biggest blockers at DoorDash - excited to see the rapid model progress in making agentic coding superhuman!

WOW! We are floored by the reception we received at our booth today, and our mixer tonight is now at full capacity. We enjoyed sharing DoorDash Dot with all of you today. DoorDash is one of the few co’s in the world building a full L4 autonomy stack in-house 🤖🦾

This new research on US unicorn startups is really interesting. Some key facts from the report: 1. Immigrants founded or cofounded 455 of America’s 775 privately held billion-dollar startups, equal to 59% of all US unicorns. 2. 66% of all US unicorns were founded or cofounded by immigrants or the children of immigrants. 3. 79% of US unicorns have either an immigrant founder or an immigrant in a key leadership role. 4. The 455 immigrant-founded US unicorns have a combined valuation of $5 trillion. 5. That $5 trillion valuation is larger than the total stock-market value of companies listed in all but 7 countries. 6. Including immigrant-founded unicorns that went public since 2016 pushes the total value above $5.8 trillion. 7. The number of immigrant-founded US unicorns rose from 50 in 2018 to 455 in 2026. 8. 24% of US unicorns have a founder who first came to America as an international student.

We ran out of whiteboard space and are on the walls @AIatDoorDash Come push the frontier with us - we’re looking for summer and fall research fellows. Any education or experience level, unlimited compute, mentorship from senior researchers, and full publication support + a very generous stipend.
