Exclusive: Paying for frontier AI models buys 4-month head start at 5x the cost

Ars Technica 1 month ago 47 ● 9 sources

Mozilla reports the performance gap between US frontier AI models and top Chinese open-weights models has narrowed to 4.4 months, changing how companies choose between them. It says Kimi K3 scores only 3 points behind Anthropic’s Fable 5 while costing 30 percent as much. The result is a shift toward open models as the default for most routine work, reserving paid closed models for specific heavy workloads like expert tasks and long-context retrieval.

A theoretical separation between quantum computers & LLMs

IBM Research 1 month ago 41

Researchers proved a theoretical separation showing shallow quantum circuits outperform limited transformer-style LLM models on specific computational tasks, both for returning correct values and for sampling from a target distribution. The circuit depth stays close to constant while the functional separation uses an iterated index problem solved by a close-to-constant-depth quantum circuit with a single classical AND gate. The work expands the known frontier of quantum-vs-classical lower bounds by extending them against stronger LLM capabilities like chain-of-thought and by motivating benchmarks for comparing quantum systems to LLMs.
