New Capabilities

Developer of Kimi K3; in early-stage revenue-sharing talks with US cloud providers

Companies can now deploy Moonshot AI's Kimi K3, a 2.8-trillion-parameter open-weight model, on Amazon Bedrock with the same security controls reserved for proprietary models. It is the largest open model on the service, with native vision, a 1-million-token context window, and explicit prompt caching, an open-model first on Bedrock.

Provider of Kimi K3 base model

Cognition released SWE-2, a coding model that scored 92.8 on Terminal-Bench 2.1 and 50.0 on FrontierCode 1.1 Main, within one point of Anthropic's Claude Fable 5.1. Cognition claims SWE-2 costs 64% less than Fable 5.1 for that performance.

Chief open-weight rival

Alibaba's Qwen3.8-Max weights landed on Hugging Face on August 12, nine days after the API launch. The download is smaller than promised: it skips the 1-million-token context and image input of the hosted model, and the 27-billion-parameter version has not shipped.
