Grok 4.6, Gemini 3.7 Flash and GLM-5.3 arrive in four days

Week of 10 August 2026: xAI, Google and Z.ai each ship a coding-focused model, Meta opens Muse Glimmer, and NVIDIA releases Nemotron 3.5 Lightning.

By , published

What shipped

  1. xAI

    Grok 4.6

    Builds on Grok 4.5 with a focus on long-running agents and interactive, visual work, with a 500K window and effort settings up to xhigh.

  2. Google DeepMind

    Gemini 3.7 Flash

    Google's generally available workhorse for coding and agents, with a 1M-token window, 64K output and thinking levels from low to high.

  3. Z.ai

    GLM-5.3

    A coding-first post-training of the GLM-5.2 base for long-horizon software work, with open weights promised after safety hardening.

  4. Meta

    Muse Glimmer 30B

    A 30B open-weight multimodal agent model under Apache 2.0, distilled from Muse Spark and sized for consumer GPUs.

  5. NVIDIA

    Nemotron 3.5 Lightning

    A 30B hybrid Mamba-Transformer with only 3B active parameters and up to 1M-token context, open weights in several precisions.

  6. InclusionAI

    Ling-3.0-tiny

    A 7.9B hybrid-reasoning model with 1.3B active parameters under MIT, validated for local use on DGX Spark and Apple Silicon.

  7. Google DeepMind

    SL2T sign-language-to-text

    A sign-to-text model that runs on pose landmarks on the device, so no raw video leaves the phone, starting with American Sign Language.

  8. arXiv

    BDH-CQ: In-Context Learning with Recurrent Latent Reasoning

    The most upvoted paper on Hugging Face that week, proposing a reasoning model whose recurrent memory updates as inputs arrive at inference.

The release calendar looked like a relay race this week. Three labs handed over a new coding model within four days of each other.

Grok 4.6

xAI put out Grok 4.6 on 12 August. The announcement says it builds on Grok 4.5 and focuses on long-running agents and more ambitious interactive and visual work, the kind of job where a model stays on task across many steps: researching a topic, working through a codebase, turning an idea into a finished app. The API lists text and image input, a 500K context and reasoning effort from low to xhigh. It is also offered inside Cursor and Grok Build.

Gemini 3.7 Flash and GLM-5.3

Google released Gemini 3.7 Flash on 13 August and calls it its most intelligent workhorse model. It takes text, image, video, audio and PDF, has a 1M-token window and 64K output, and supports thinking at low, medium and high.

Z.ai followed on 14 August with GLM-5.3. It is a post-training update on the same GLM-5.2 base, tuned for complex software engineering and long-horizon coding. The weights are not out yet: Z.ai says open weights come after safety hardening, so I'd treat it as an API model for now.

Open weights, the other end of the size range

Meta released Muse Glimmer on 10 August, a 30B open-weight multimodal agent model under Apache 2.0, distilled from its proprietary Muse Spark and sized for a consumer GPU. NVIDIA released Nemotron 3.5 Lightning on 11 August: 30B total, 3B active, a hybrid Mamba-Transformer design, with context listed up to 1M tokens. InclusionAI added Ling-3.0-tiny, a 7.9B model with 1.3B active that runs on a DGX Spark or a Mac.

Sign language on the phone

On 12 August DeepMind described SL2T, a sign-language-to-text model now behind dictation in Gboard and Live Transcribe on Pixel 11, starting with American Sign Language. It works from pose landmarks captured on the device rather than raw video, which is a sensible privacy choice. DeepMind reports training on more than 100,000 hours across over 50 sign languages.

The paper that drew the most attention was BDH-CQ, a reasoning model with a recurrent memory that updates as it reads its inputs.

What I'd watch next

Whether Z.ai actually opens the GLM-5.3 weights on the timeline it hints at.
