Hunyuan 2.0 Thinking

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.

Gander

Tencent

Gander is a 9B full-duplex audio-visual interaction model developed by Tencent’s Hunyuan Speech team with academic collaborators. Its MiniCPM-o 4.5-derived Thinker and streaming Talker handle speech, images, video frames, text, turn taking, interruption, and structured delegation while tasks continue asynchronously. Apache-licensed model components and a serving runtime are publicly available. The larger system pairs this conversational model with a separately configured reasoning agent for long-horizon execution; those back-end model capabilities are not assumed to reside inside the 9B checkpoint. The release date follows the September 8 technical report that publishes the named model; the project dates its checkpoint release to September 9.

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.
