AI Coding Spend Soars 16x; PR Velocity Doubles
A new analysis by The Pragmatic Engineer, based on data from 27 companies plus CodeRabbit and Gitar, reveals dramatic increases in AI spending for software engineering. CodeRabbit data shows weekly PRs per developer doubled (113% increase), while Gitar reports AI-native teams shipping 60+ PRs per developer weekly. Spending patterns vary widely: a quant trading firm's AI spend ballooned from $500K to $8M monthly (16x), averaging $1,600 per developer monthly, while a two-person .NET shop spends $3,000 per developer monthly. High spenders like Meta and NVIDIA encourage heavy AI use, while Apple engineers remain cautious. Median spend is around $300-500 per developer monthly, with common spending caps. Notably, despite increased PR counts, several companies report flat or modest velocity gains, with one engineer noting that quality-focused teams see little speed increase. The article highlights challenges in measuring ROI and the shift to models like Claude Opus 5.5.
This analysis provides concrete data on AI adoption and ROI in software engineering, relevant to AdTech as AI-driven development tools impact efficiency and cost structures across tech companies. It highlights trends in AI spending and productivity that could influence how AdTech companies evaluate AI investments.

Report: High AI Spenders See Headcount Growth
A TechCrunch article summarizes a new report from Ramp and Revelio Labs analyzing enterprise AI spend and workforce records across nearly 22,000 companies. The report finds that "high-intensity adopters" — firms spending about $30 per employee per month on AI initially — experienced a 10.2% increase in headcount, with entry-level roles rising (12%) at tech-forward firms. Growth occurred across engineering, sales, admin, customer service, finance, marketing and scientist roles, especially in the information sector. The article contrasts these findings with other research (e.g., Goldman Sachs) showing net job losses tied to AI, and notes the report’s caveat that gains are concentrated among already fast-growing, well-resourced companies, creating a potential widening gap between firms that scale AI investments and those that only pilot subscriptions.
AI Coding Costs Surge; OpenAI, Databricks, Claude Drive News
This AI news digest covers key developments from September 15-16, 2026. Notably, Databricks reported a 60% increase in coding spend after rolling out GPT-6 Astra to 3,500 engineers, despite its superior performance on complex tasks. OpenAI formalized an incident disclosure framework for model misalignment. Anthropic unified Claude chat and 'work' into a single agent surface, while Xiaomi's MiMo-V2.6 set a new bar for public RL run telemetry. The digest also highlights the emergence of Union Alpha as a low-cost coding model in Cline, Cohere's acquisition of Aleph Alpha, and Arcee's Series B at a $1B+ valuation.
Gartner: AI coding costs may exceed developer pay by 2028
A Gartner forecast warns that costs for AI-assisted coding could surpass the average developer salary by 2028 due to surging token consumption and a shift to usage-based licensing. Corporate pressure to maximize AI usage — exemplified by targets and performance metrics at firms like Amazon and internal encouragement at Nvidia and Meta — can inflate token usage and reduce measurable productivity gains for many employees. Surveys and reports cited by the article show executives are optimistic about AI time savings while many developers see little or no weekly time saved. Several firms have already felt the financial strain: one customer reportedly spent $500 million in a month on Claude licenses without restrictions, Microsoft is cutting back on Claude licenses, and some companies have pursued layoffs or other cost measures. Analysts and trade groups warn that lack of transparency in pricing and weak governance of model usage make AI spending volatile and hard to control.
