Thisblog post is a different kind.It’s a deep dive explanation of how Open Deep Research works under the hood and which design patterns are applied to makeit one of the best open source deep research agents. How is this post different from other resources? The LangChainGitHub repo andblog posts provide only high-level explanations of how things work. LangSmith and LangGraph Studio don’t expos

GPT-5.2 is our newest flagship model for enterprise and agentic workloads, designed to deliver higher accuracy, stronger instruction following, and more disciplined execution across complexworkflows.Building on GPT-5.1, GPT-5.2 improves token efficiency on medium-to-complex tasks, produces cleaner formatting with less unnecessary verbosity, and shows clear gains in structured reasoning, tool gro
AI agents have moved from experimental to an essential part of an organization’stech stack. But how are enterprises actually using them? In partnership with research firm Material, we surveyed over 500technical leaders across industries and company sizes to understand how organizations are deploying agents today and where they see opportunity ahead. The findings show a clear pattern: organizatio

Estimated reading time: 6 minutes When you’re integratingAI into engineeringworkflows, reliability, robustness, and fit are key concepts to consider. Before we built anAI system that could write integration code for us, we had to confront asimple question thatshaped the entire project. What actu

Autofix CI failures with CodexEmbed the Codex CLI intoGitHub Actions so failed CI jobs trigger automatic fixes and reviewable pullrequests. Codex can keep your continuous integration (CI) signalgreen by running automatically whenever aworkflow fails. Thisguide adapts the official Codex cookbook soGitHub Actions can invoke the Codex CLI, apply targeted fixes, verify tests, and open a pull re

Prompt design is the process ofcreating prompts, or natural languagerequests, that elicit accurate, high quality responses from a language model. This page introduces basic concepts, strategies, and best practices to get you started designing prompts to get the most out of GeminiAI models.Topic-specific promptguides Looking for more specific prompt strategies?

When you add or modify data in the source column, BigQuery automatically generates or updates th
Note: this post is also applicable to AGENTS.md, the open-source equivalent of CLAUDE.md for agents and harnesses like OpenCode, Zed, Cursor and Codex. ## Principle: LLMs are (mostly) stateless LLMs are stateless functions. Their weights are frozen by the time they're used for inference, so they don't learn over time. The only thing that the model knows about your codebase is the tokens you put in
Published Nov 26, 2025 Agents still face challenges working across many contextwindows. We looked to human engineers for inspiration increating a more effective harness for long-running agents. AsAI agents become more capable, developers are increasingly asking them to take on complex tasks requiring work that spans hours, or even days. However, getting agents to make consistent progress across
