It also sets new state-of-the-art results on Terminal‑Bench 2.1 and DeepSWE, which test complex command-line workflows and long-horizon engineering in real codebases.”\n\nThere are also harder-to-benchmark improvements in computer use, presentation/document generation, and scientific research that should nevertheless be taken very seriously.\n\nAs we [predicted in April](https://www.latent.space/p/ainews-gpt-55-and-openai-codex-superapp?utm_source=publication-search), the newly launched [ChatGPT Work](https://x.com/OpenAI/status/2075274271845404744?s=20) and Codex desktop app update today is probably the penultimate step for OpenAI’s superapp strategy (the last open question is what happens to the agentic browser….)\n\nAI News for 7/08/2026-7/09/2026.

increase output and automate chunks of RL/post-training workflows, even if public discussion often overstates that as “the model trained itself”\n\nThe launch also sharpens a recurring engineering question raised by many tweets: whether the frontier is now bottlenecked less by a single monolithic model and more by\n\n**orchestration quality, tool APIs, subagents, evaluation harnesses, and
