# AI News Digest - 2026-07-09

1. OpenAI introduced GPT‑Live, a full‑duplex system that listened and spoke simultaneously, routed complex questions to GPT‑5.5 in the background, and made GPT‑Live‑1 available to paying ChatGPT users with a smaller version for free accounts while API access was announced as forthcoming.

2. Anthropic released Claude Fable 5 and it topped new industry‑specific benchmarks but incurred steep per‑task costs; the company advised using Fable 5 as a planner that delegated work to Sonnet 5 in an "Advisor" pattern to recover about 92 percent of Fable 5's solo performance at roughly 63 percent of the cost.

3. xAI released Grok 4.5, which was trained on tens of thousands of Nvidia GB300 GPUs, lagged Fable 5 and GPT‑5.5 on coding benchmarks but required 4.2 times fewer tokens than Opus 4.8 and offered input‑token pricing at $2 per million, with EU availability expected in mid‑July.

4. MiniMax announced plans to open‑source a 2.7 trillion‑parameter large language model later in the year.

5. Mistral entered robotics with Robostral Navigate, an 8B model that guided robots through unknown environments using only a single RGB camera, was trained in simulation and refined with reinforcement learning, and achieved 76.6 percent on the R2R‑CE benchmark.
