SpaceXAI's Grok 4.7 added to Amazon Bedrock

SpaceXAI announced Grok 4.7 is available on Amazon Bedrock with features aimed at long-horizon agent workloads: a 500K-token context window, tool calling, configurable reasoning-effort levels (low/medium/high/xhigh), and support for Chat Completions/Responses and the Bedrock Converse API. In SpaceXAI's tests of a tool-calling agent on three search-style tasks, the agent answered 67 of 72 runs correctly (18/18 at xhigh; 15/18 at low), illustrating a tunable trade-off between correctness and token use; Bedrock access uses cross-Region inference profiles and requires specific IAM permissions.

Moonshot AI's Kimi K3 (2.8T, 1M-token) now available on Amazon Bedrock

Moonshot AI's Kimi K3 is now available on Amazon Bedrock. Per Moonshot, Kimi K3 is the company's most capable open-weight model (2.8 trillion parameters) with native vision, a 1‑million‑token context window, and ~2.5x scaling-efficiency improvement over Kimi K2; Bedrock also supports explicit prompt caching, Responses/Chat Completions APIs, regional/global inference profiles, and AWS data protections (zero data retention and zero operator access).
