Advanced Evals Guide: Finding Hidden AI Failures
This article is a comprehensive guide on advanced evaluation (evals) practices for AI products, authored by Hamel Husain and Shreya Shankar. It emphasizes the importance of error discovery before writing metrics, contrasting it with product discovery. The authors outline a three-step process for effective error discovery using coding agents like Codex or Claude, highlighting the pitfalls of automation bias and criteria drift. They introduce an open-source 'evals skills' plugin that assists in trace review and clustering. The article cites real-world examples from companies like Shopify, Cursor, Ramp, and Harvey, demonstrating how evals have led to significant product improvements. The piece also discusses synthetic data generation and the importance of human-in-the-loop annotation, recommending a target of 100 traces for meaningful analysis.
- Shopify used evals to build an AI workflow builder that was 2.2x faster and 68% cheaper than the frontier-model system it replaced.
- Cursor developed its Auto Balance routing performance with evals, reducing costs by 41%.
- Ramp increased its automatic receipt collection product's accuracy from 35% to 83% after investing in evals.

SpaceX AI and Meta Compete for 2027 AI Agent Market
This article analyzes the emerging competition in the AI agent market, focusing on SpaceX AI's Grok Bot and Meta's Muse as potential challengers to OpenAI's ChatGPT. Grok Bot, developed with Cursor, is an autonomous AI agent platform included in Cursor's paid plans, while Meta's Muse launched in September 2026. The article discusses their impact on OpenAI's market share, especially as OpenAI delays its IPO amid competitive pressures. It highlights capabilities like isolated cloud machines, asynchronous tools, and human-in-the-loop safeguards. The author also mentions Anthropic's Claude Cowork and Google's Gemini as competitive products. The piece concludes that these agentic systems may reduce reliance on traditional chatbots.
- SpaceX AI completed acquisition of Cursor for $60B on August 14, 2025.
- Grok Bot was introduced on August 11, 2026 as an autonomous AI agent platform.
- Meta launched its personal AI agent Muse on September 8, 2026.

Mistral CEO Warns Against Closed AI Model Vendor Lock-In
Arthur Mensch, co-founder and CEO of Mistral AI, published a LinkedIn post urging enterprise leaders to avoid dependence on proprietary, closed AI models. He argues that providers of such models gain "immense leverage" by observing how companies integrate AI into their business context, learn from that data, and may eventually compete with their most successful customers. Mensch recommends building independent AI infrastructure using open-source models, storing data in open systems, enforcing strict AI access management, and creating a continuous internal training flywheel. He also promotes Mistral's "Studio" control plane and "Forge" training platform, emphasizing sovereign, zero-data-retention deployments. The article notes that his claims partly overlap with documented cases, such as Anthropic cutting off Windsurf's model access, but says he offers no evidence for deliberate customer targeting. Palantir CEO Alex Karp has also recently warned against vendor lock-in in enterprise AI.
- Arthur Mensch, co-founder and CEO of Mistral AI, warned enterprises against reliance on closed AI models in a LinkedIn post.
- Mensch argued closed model providers gain leverage by observing customer data and learning from business integrations.
- The article cites Anthropic cutting off coding startup Windsurf's model access in 2025 while building rival product Claude Code.
