OpenAI's GPT-Live can listen and speak at the same time using a full-duplex architecture. Complex questions get handed off to GPT-5.5 in the background, which drastically improves response quality. GPT-Live-1 is available now for paying ChatGPT users, with a mini version for free accounts. API access is coming soon.

Anthropic recommends using the expensive Claude Fable 5 mainly as a planner for smaller models instead of running it on every task. Combined with Sonnet 5 in the "Advisor" pattern, this setup hits 92 percent of Fable 5's solo performance at 63 percent of the cost.

Anthropic's Claude Fable 5 tops all six new industry-specific performance indices from Artificial Analysis, covering finance, law, and medicine. But that lead comes at a steep cost. In the Strategy & Ops Index, a single task runs $3.48 with Fable 5, more than a hundred times what DeepSeek V4 Pro charges at $0.03. The score difference is just 12 points.

xAI releases Grok 4.5, trained on tens of thousands of Nvidia GB300 GPUs. In coding benchmarks, the model trails Fable 5 and GPT-5.5 but needs 4.2 times fewer tokens than Opus 4.8. At $2 per million input tokens, it costs a fraction of the competition. EU availability is expected in mid-July.

Chinese AI developer MiniMax is working on a new large language model with 2.7 trillion parameters. MiniMax plans to release the model as open source.

Mistral is entering the robotics market with Robostral Navigate, an 8B model that guides robots through unknown environments using only a single RGB camera. Trained in simulation and refined with reinforcement learning (CISPO), it hits 76.6 percent on the R2R-CE benchmark. Mistral hasn't said when the model will be available.
