But understanding what matters and what it means for your organization has never been more important. That's why this edition of the Thoughtworks Technology Radar is essential reading. Based on the real-world experiences of Thoughtworkers, it's an opinionated guide to the technologies and practices we think deserve your attention. Taking in everything from AI coding assistants to testing tools and techniques, the Technology Radar isn't a trend report: it's a deep dive into the complex realities of software engineering right now. Read Technology Radar Vol.34 🚀 Headlines & Launches Claude Opus 4.7 (8 minute read) Anthropic has released Claude Opus 4.7, offering improved performance on difficult engineering tasks, stronger vision capabilities, and more reliable long-running task execution compared to its predecessor. OpenAI's GPT Rosalind (8 minute read) OpenAI introduced GPT‑Rosalind, a specialized model designed to support drug discovery and biological research through improved reasoning, tool use, and integration with scientific data sources. Codex Expands Into Full Computer Automation (6 minute read) OpenAI updated Codex with background computer control, multi-agent workflows, and deeper integration with developer tools, extending its role across the full software development lifecycle. The Computer is Personal (4 minute read) Perplexity launched "Personal Computer," an AI platform that shifts the operating system model from manual instruction execution to probabilistic goal completion. The agent utilizes deep web research as its core foundation to autonomously evaluate reasoning paths and drive multi-step workflows. This architecture transforms the computer into an active orchestrator, eliminating the administrative friction of managing fragmented software tools. 🧠 Deep Dives & Analysis Jensen Huang on Anthropic, OpenAI, China, and demand for inference tokens (7 minute read) Jensen Huang recently appeared on an interview where he discussed mostly familiar topics. However, there were three exchanges where Jensen said more than he probably intended. Jensen even lost his composure when discussing China and whether sales of chips should be restricted in the region. This post details each of the exchanges and notes other observations about the interview. What I learned this week (20 minute read) This post contains rough notes on pretraining parallelisms, whether distillation can be stopped, Mythos and the cybersecurity equilibrium, Pipeline RL, and why pretraining runs fail. The PR you would have opened yourself (12 minute read) A new Skill and Test Harness help port transformer models to mlx-lm, streamlining contributions and reviews. This tool assists contributors by managing model conversion tasks and provides reviewers with agent-assisted PRs complete with comprehensive reports. It aims to maintain code quality and improve efficiency in an open-source environment where manual review cannot scale. 🧑‍💻 Engineering & Research 11 days to DigitalOcean Deploy: the AI inference era is here (Sponsor) DigitalOcean Deploy is April 28 in San Francisco. One day focused on production inference at scale. Real customer stories, a fireside with NVIDIA's Kari Briski on agentic AI, and a first look at DO's next-gen inference products. Speakers from Character, Workato, VAST Data, Arcee, and vLLM. In-person seats are limited, so claim yours! Register now Qwen 3.6 and Agentic Coding (GitHub Repo) Qwen 3.6 introduces stronger repository-level reasoning and front-end workflow handling, along with a thinking preservation feature that maintains context across iterations. Introducing Ternary Bonsai: Top Intelligence at 1.58 Bits (4 minute read) Ternary Bonsai is a 1.58-bit language model family offering improved performance with minimal memory usage. It outperforms 1-bit counterparts, scoring 75.5 on average benchmarks and achieving 3-4x better energy efficiency. The models, available in 8B, 4B, and 1.7B versions, provide flexible deployment across devices like Macs and iPhones under the Apache 2.0 License. Sandboxed Agents for Codebase Migration (19 minute read) This guide outlines a structured approach to modernizing large codebases using sandboxed agents that operate on isolated tasks, validate changes, and return auditable patches while orchestration remains outside the execution environment. 🎁 Miscellaneous Anthropic Exec Leaves Figma Board Amid Product Tensions (2 minute read) Anthropic's chief product officer stepped down from Figma's board following reports that upcoming models may include design tools competing with Figma's core product. OpenAI to spend more than $20 billion on Cerebras chips, receive stake, The Information reports (2 minute read) OpenAI will pay Cerebras more than $20 billion over the next three years to use servers powered by Cerebras' chips. The deal may also give OpenAI an equity stake in Cerebras. OpenAI has also agreed to provide Cerebras with about $1 billion to help fund the development of data centers. Cerebras is targeting an IPO in the second quarter of this year. ⚡ Quick Links TLDR is hiring a Senior Software Engineer, Applied AI ($250k-$350k, Fully Remote) TLDR's Applied AI team is tasked with making every process at TLDR legible to code, runnable by anyone, and composable into larger workflows.
