The rise of AI engineering is shaping a new 'AI SDLC'. Beyond using a great model, success seems to hinge on precise, task-specific evaluations. Are you actually testing your prompts or going by "gut feel"?
Love this collab with @ZacharyZaro !
🔓 We just automated the impossible: AI that instantly understands ANY company's APIs and unlocks hidden insights in their customer data. Using @AnthropicAI's Claude Code + @daytonaio, we generate production-ready integrations in minutes, not weeks.
Is there an easy way to drop a “chat with my existing backend endpoints” into my app dashboard?

In summary, as can be gleaned by the responses to my post: x.com/BillAckman/sta… those opposed to America assisting Israel in destroying Iran’s nuclear reactors make the following arguments: “It’s not our problem. We shouldn’t put U.S. lives at risk for Israel’s war. It…
The parade was great. Our military is incredible. And now @Israel needs our help to destroy Iran’s nuclear threat to the world. Israel’s military and air force have sufficiently degraded Iran’s defenses such that this is now the lowest-risk, highest-probability moment to take…

No team has ever come back from 20+ twice in a row in the playoffs until tonight and the @nyknicks. What a display of mental toughness and never giving up!
Introducing Daytona Cloud: the first agent-native cloud infrastructure. Fast. Stateful. Built for agents, not humans. Available today.

Rippling sued @Deel today. Our lawsuit alleges Deel cultivated a spy at Rippling & orchestrated a long-running trade-secret theft. The spy searched “deel” in our systems 23 times per day on avg, letting him spy on Deel’s own customers who were considering a switch to Rippling.

Wow! Pseudo-panspermia now has very strong evidence. In Jan 2025, NASA reported organic compounds, all 5 nucleobases for RNA/DNA, and amino acids (of both left/right chirality!) were found on an asteroid older than the earth, likely originating from early outer solar system.
The US taxpayer should not be exit liquidity for cryptocurrencies that are decentralized in name only.
AI development doesn't have to feel like guesswork. We built Coherence (withcoherence.com) to remove the manual pain of prompt optimization. Test faster, improve continuously, collaborate across teams. Curious how it works? DM me or hit the comments.
Thread featuring the best quotes from one of the most underrated books on the U.S., 'Without Marx or Jesus: The New American Revolution Has Begun' by Jean-François Revel.
Watched a nation turn its page today. Old divisions feel small against the work ahead of us. May providence light our shared journey ahead.
The LLM ecosystem is evolving rapidly, but the way we test prompts hasn’t caught up. Prompt errors = unpredictable AI behavior 😵💫 And yet, most teams lack formal tools for continuous testing and refinement. Would you trust an app with zero automated tests? Why trust prompts…
Prompt engineering is the backbone of AI-native products. But let’s be real—getting prompts right is HARD. Most teams are stuck in manual, endless testing loops. How are you optimizing your prompts? Share your process below.
