A Week of New Models and a Major Harness Update from OpenAI

This week delivered a barrage of model releases—GPT 5.6, Grok 4.5, and the surprise Muse Spark 1.1 from Meta—but the most consequential news may be OpenAI's new "ChatGPT Work" harness, which extends the agentic approach that made Codex successful for coding into general knowledge work. The week also included Cursor's plans for a general-purpose agent, OpenAI's formal retraction of support for the SWE-bench Pro coding benchmark, and a new national security principles document from OpenAI.

The GPT 5.6 Family: Performance Per Cost Becomes the Story

OpenAI officially released the GPT 5.6 model family, split into three tiers: Sol (flagship), Terra (mid-size), and Luna (small, cost-efficient). The benchmark presentation marked a shift—instead of simple score tables, OpenAI emphasized charts showing performance per cost, per latency, and per output tokens. Sam Altman tweeted that enterprises had voiced concerns about AI costs, and that "5.6 Sol is a huge step forward for dollars per task."

Show Notes

OpenAI’s new ChatGPT Work brings the agentic systems that transformed coding into the broader world of knowledge work, allowing AI to operate across apps, files, and long-running projects. NLW breaks down what the new harness means, how GPT-5.6 compares with Fable 5, and why efficiency has suddenly become the defining battleground in the model race. In the headlines: Cursor expands beyond coding, OpenAI rejects a leading coding benchmark, and Meta accelerates its AI infrastructure push.
