Grok 4.7

xAI

Grok 4.7 is a proprietary xAI language-model release. The September frontier update improves coding, agentic tasks, and knowledge work and is available through the API. It uses text and image inputs and text output, configurable reasoning effort, and tool interfaces. A faster serving option uses the same underlying model and is recorded as a deployment variant, not a separate checkpoint. Weights are not publicly downloadable. Published agent and coding results depend on the evaluation harness, tool permissions, and inference settings, so no unsupported standalone benchmark score is assigned.

Muse Spark 1.3

Meta

Muse Spark 1.3 is a proprietary Meta multimodal reasoning model for coding and agentic knowledge work. The 1.3 update improves long instruction adherence, multi-task coordination, self-awareness of task limits, and cooperation with users during extended work. It accepts text, images, video, and audio and produces text; the API specifies a 1,048,576-token context for these versions. Standard and, where offered, Contributor access use the same model capabilities but different data-use terms. Contributor access is a serving tier rather than a separate model. Future open-weight plans are not a weight release.

Agnes 3.0 Flash

Agnes AI

Agnes 3.0 Flash is Agnes AI’s hosted production model for coding agents, reliable tool orchestration, long-running task execution, and instruction following. Its API supports text and image URL input with text output through Chat Completions, Responses, and Messages-compatible interfaces. The current API guide specifies 512K context and a 65,536-token output limit. The provider’s separate Preview weight card describes a 1M production configuration, so this page follows the lower documented serving contract. Production parameters and architecture are undisclosed, and the downloadable 33B Apache Preview is explicitly a different checkpoint. September month precision avoids assuming that repository publication dates describe the hosted launch.
