OpenAI has begun a limited preview of the GPT‑5.6 family: **Sol** (flagship), **Terra** (balanced, 2× cheaper than GPT‑5.5), and **Luna** (fast, low‑cost). Sol introduces a new “max” reasoning mode and an “ultra” mode that uses sub‑agents. Early benchmarks show state‑of‑the‑art performance on coding (Terminal‑Bench 2.1), biology (GeneBench v1), and cybersecurity (ExploitBench, ExploitGym). The models ship with OpenAI’s most robust safety stack to date, but the preview may block or delay some requests.
NVIDIA AI announced the release of Nemotron 3 Ultra, a 550 B MoE model that speeds inference fivefold, lowers agentic task costs up to 30 % and excels at coding, deep research, and long‑horizon planning. OpenCode noted that Nemotron 3 Ultra is now free with 1 M context and fully open source. Ollama said the model is available on its cloud platform, offering launch commands for Claude, Hermes and OpenClaw. OpenAI introduced a new memory system for ChatGPT that automatically tracks important details, doubles memory capacity for Plus and Pro users in the US, and lets users review and steer remembered content via a summary. Cursor added an interactive context‑usage report in its canvas, breaking down token distribution across prompts, tools, rules and skills.
