Tencent open-sources Hy4 preview: 770B / 49B-active MoE with Gated DSA + iHC, 1M context, Apache 2.0
TencentTencent's Hy team open-sourced Hy4 preview and an FP8 variant on Hugging Face, ModelScope, GitCode and CNB on Aug 27-28, 2026. It is a 770B-total / 49B-active MoE (78 layers, 1 dense + 77 MoE with 256 routed + 1 shared expert, top-8 routed), with a native MTP layer (10B/0.7B-active) for speculative decoding, Gated DeepSeek Sparse Attention with IndexCache cross-layer sparse index reuse, and identity Hyper-Connections (iHC) on the residual pathway. Native context is 1M tokens, vocabulary 120,832, and weights are released under Apache 2.0. Tencent's internal blind eval (163 experts, 203 engineering tasks) puts Hy4 preview slightly ahead of GLM-5.3 (2.99 vs 2.92; 46.8% wins / 12.8% ties / 40.4% losses) and Kimi K3 (2.99 vs 2.94; 51.2% wins / 7.9% ties / 40.9% losses).
Long-Horizon Audio-Visual Generation for Persistent Stories and Interactive Worlds
Introduces JoyAI-Echo-1.5, a unified audio-visual generation system with two variants — long-form narrative video and an interactive 6-DoF world model — built on composable cross-shot memory, speech-filtered audio cues, and a causal few-step generator trained with progressive teacher forcing and Self-Gradient Forcing.
Anthropic opens Model Hardware Standard (MHS) research preview for AI agents operating lab devices, built with HHMI Janelia
AnthropicOn Aug 27, 2026 Anthropic opened a research preview of the Model Hardware Standard (MHS), a shared specification designed to let AI agents safely operate physical lab equipment such as microscopes, liquid handlers and robotic arms. Co-developed with HHMI Janelia, the spec reportedly cuts device-integration time from weeks to hours; partners Genentech, the University of Washington, Carnegie Mellon, HHMI Janelia, QuEra and Tetsuwan demonstrated early applications across drug discovery, protein design, quantum computing and environmental science.
OpenCode v1.18.24 + v1.18.25 add Microsoft Entra ID sign-in for Azure, Bedrock reasoning cache fix, and Desktop archive-cleanup
SSTv1.18.24 (Aug 28): Bedrock reasoning responses no longer get cached into unreplayable empty messages; Azure providers can now sign in with Microsoft Entra ID through the Azure CLI (no API key needed); V1 reads supported V2 config fields so newer config files keep working in mixed setups; Desktop archived sessions drop from the Home list immediately. v1.18.25 (Aug 28) follows with a follow-up fix so Azure CLI sign-in works without requiring Bun.
Anthropic SDKs coordinated v1.2.0 (Python, TS, Go, Java, Ruby, C#) promote Files and Skills APIs to GA shapes, drop beta headers
AnthropicCoordinated Aug 27, 2026 across Python v1.2.0, TypeScript v0.122.0, Go v1.68.0, Java v2.59.0, Ruby v1.67.0 and C# v12.44.0. client.beta.files and client.beta.skills no longer send the dated files-api-2025-04-14 and skills-2025-10-02 beta headers and return the same shapes as client.files and client.skills; client.beta.skills.delete() now deletes a Skill together with all of its versions; the beta Messages type BetaSkill (container Skill reference) is renamed BetaContainerSkill. Bug fixes: Bedrock binary-file upload signing (#531), sessions event-accumulator forward-compat (#533), tools read view_range over the size cap (#538), exact file-byte preservation in the agent and memory toolsets (#540), webhook unwrap() now requires headers. Same day's Claude Console release adds personal keys and service-account keys (with workspace-scoped and admin-endpoint variants). PHP 0.44.0 was not bumped in this round.

New defaults: max_num_batched_tokens 8192 to 16384, prefix caching on for Mamba, Blackwell CUDA graph capture 1024. Breaking: bitsandbytes moved OOT plugin, Transformers 5.15.0 baseline, calculate_kv_scales and override_attention_dtype removed. Online MXFP4/NVFP4; MLA CPU backend for DeepSeek-V2/V3.
Cline Desktop v0.0.20 ships first Windows release with code-signed installer, inline tool-result images, and full session search
ClineReleased Aug 28, 2026. First Windows Desktop release: code-signed x64 installer with auto-updates; background processes no longer pop console windows; MCP settings path falls back to USERPROFILE when HOME is unset. Inline image rendering for tool results with click-to-expand and a multi-image carousel. Full session search via the command bar (Cmd/Ctrl+P) with server-ranked results. New GitHub onboarding step. Scheduled tasks now persist in ~/.cline/schedules and surface their final answer on completion. Provider badges update live after credential changes. OpenAI Codex sign-in fails fast with an actionable error when callback port 1455 is in use. Checkpoint restore refuses to reset a workspace when commits were made after the checkpoint.
OpenAI Node SDK v7.8.0 adds compute_units to usage objects and WebSocket User-Agent + audit log events
OpenAIReleased Aug 27, 2026. Adds a compute_units field to Responses and Chat Completions usage objects. WebSocket connections now send a default User-Agent header and emit audit log events for connection lifecycle, so server-side logs and metrics can identify the client. Workload-identity refresh buffer clamped to the token lifetime to avoid premature expiry. X.509 first-class workload credentials secured. WebSocket waiters settle even when listeners throw. Multipart body detection now relies only on own properties, reducing prototype-chain false positives. Native browser ESM imports restored.
OpenAI Codex CLI v0.150.1 backports remote compaction fix: retained images now count toward the token budget
OpenAIReleased Aug 27, 2026 (PR #41003, by rhan-oai). Remote compaction now counts retained images toward its token budget by default and trims older images as needed, instead of letting image retention silently push the session past its limits. No new features, command changes, or breaking API modifications beyond that single change.
JD.com's Joy Future Academy releases JoyAI-Echo 1.5 — 5-minute audio-visual generation with cross-shot character and voice memory
JD.com (Joy Future Academy)On 2026-08-28, JD's Echo Team at Joy Future Academy shipped JoyAI-Echo 1.5 (Echo-LongVideo) — a unified audio-visual generation system built on Lightricks LTX-2.3 with an 8-step DMD sampler, paired cross-modal memory (image + audio slots) for character appearance and voice identity, and Gemma 3 (12B IT) as the text encoder. The reference-to-video pipeline takes a text prompt, an optional first-frame condition, and up to seven ordered reference memory slots per shot, and ships with consumer-GPU profiles via layer-wise DiT offload and tiled Video VAE decoding. Weights are released in BF16, FP8, and FP4 precisions under the LTX-2 Community License on the main branch of the open-source repo.
