Uber Reveals AI Developer Tools and Infrastructure
In a podcast episode of The Pragmatic Engineer, Uber Distinguished Engineer Uday Kiran Medisetty details Uber's internal developer tooling and AI infrastructure. Uber has built extensive in-house systems like DevPods, M3DB, Cadence, and Morpheus due to the lack of off-the-shelf solutions at their scale. The company has invested in a Model Gateway for AI model abstraction, AIFX for harness switching, and implements a hybrid AI spend model with cost tracking via CostCheck. They have also adapted code review processes with AI-assisted tools and risk scoring. Uber tags PRs by type (feature, bugfix, maintenance, testing, docs) to better measure productivity, as traditional PR velocity is less relevant with AI agents. The episode highlights a 'code red' for CI due to doubled jobs, leading to shifts of simple tasks to the 'inner loop'. Uber's AI tooling builds on a decade of dev tooling investments, enabling quick AI agent integration.
The news provides a detailed, technical look into Uber's internal AI developer infrastructure and tooling, which is relevant to AdTech and MarTech as AI-driven development and agentic systems are reshaping engineering workflows. The insights on Model Gateway, AIFX, and cost optimization are valuable for technology leaders in advertising and marketing tech.

Uber Engineers Create AI Chatbot of CEO for Productivity
Uber CEO Dara Khosrowshahi said in an interview on Steven Bartlett’s podcast that Uber engineers have built an internal chatbot — referred to internally as a “Dara AI” — which teams use to rehearse and tune presentations before meeting senior leadership. Khosrowshahi said roughly 90% of Uber’s software engineers use AI tools in their work and about 30% are “power users” who are rethinking the company’s software architecture. The detail was reported by Business Insider and published by TechCrunch on February 24, 2026. Khosrowshahi described the tools as substantially increasing engineering productivity.
Uber caps employee AI spending at $1,500 monthly
Uber has instituted internal usage caps to rein in rapidly rising AI costs, placing a $1,500 monthly limit per employee and per agentic coding tool (examples cited include Anthropic’s Claude Code and Cursor). The company tracks usage via an internal dashboard and allows exceptions with permission. The cap follows a disclosure by Uber’s CTO that the company exhausted its annual AI budget within four months after encouraging heavy employee use and running internal usage leaderboards. Uber COO Andrew Macdonald has also publicly questioned the clear productivity gains from AI. The move underscores growing enterprise scrutiny of AI ROI as organizations confront rising inference and tooling expenses.
Uber Integrates OpenAI for Driver Assistant and Voice
Uber has partnered with OpenAI to embed large language models and Realtime APIs into its mobile experience, launching AI-powered features to help drivers optimize earnings and to enable voice-based ride booking for riders. Uber developed "Uber Assistant," a multi-agent system that routes queries to specialized models and includes an internal governance layer called AI Guard to enforce safety, policy, and latency constraints. Voice booking using OpenAI Realtime APIs is being rolled out to let riders speak full intents and receive synchronized spoken and visual recommendations. Uber reports an experimental U.S. rollout: hundreds of thousands of drivers have access to the beta Assistant. The company says these integrations speed product iteration, improve accessibility, and reduce cognitive overhead for drivers while enabling faster conversational responses for customers.
