Tencent Officially Releases Hunyuan Hy3: 295B MoE Model with Agent and Reasoning Capabilities
TencentTencent officially launched Hy3, a 295B-parameter Mixture-of-Experts model with 21B active parameters and a 256K-token context window, under Apache 2.0. The model achieves 90% agent task-completion on Tencent's enterprise platform WorkBuddy, 78.0 on SWE-Bench Verified, and 90.4 on GPQA Diamond. Weights are available on Hugging Face (tencent/Hy3 and tencent/Hy3-FP8) and ModelScope; free API access via OpenRouter runs through July 21.
Sber Releases GigaChat 3.5 Ultra: 432B Open-Source MoE Flagship
SberSber released GigaChat 3.5 Ultra on July 6: a 432B Mixture-of-Experts model built on a proprietary linear-attention architecture. The model is ~38% smaller than the prior 700B GigaChat 3.1 Ultra, generates long texts up to 4× faster, and approaches DeepSeek 3.2 on coding, math, and multi-step reasoning benchmarks. Available free in the GigaChat app and released as open source on Hugging Face and GitVerse.
A Global Workspace in Language Models
AnthropicAnthropic researchers identified a privileged internal space in Claude — J-space — using a new Jacobian lens technique. J-space is a compact set of verbalizable representations (~10% of total neural activity) acting as a cognitive workspace for reportable thoughts, multi-step reasoning, and silent deliberation. Critically, J-space can expose covert behaviors — Claude privately recognizing test scenarios, data fabrication, or prompt injection — before any output is produced. Code is released open-source (Apache-2.0) at anthropics/jacobian-lens.

Fable 5 Exits Claude Subscription Plans, Moves to Usage Credits
AnthropicFrom July 7, Fable 5 is no longer included within the weekly usage limits of Pro, Max, Team, and select Enterprise plans. Access now requires usage credits at $10 per million input tokens and $50 per million output tokens. Anthropic states the change is a capacity-management measure and intends to restore Fable 5 within subscriptions once capacity allows.
OpenAI Releases GPT-Realtime-2.1 and GPT-Realtime-2.1-mini for Voice Agents
OpenAIOpenAI released two new Realtime API models on July 6: gpt-realtime-2.1 and gpt-realtime-2.1-mini, both optimized for low-latency voice and multimodal applications. The update delivers at least 25% lower p95 latency via improved caching, plus better alphanumeric recognition, noise/silence handling, and interruption behavior.
The Mirage of Optimizing Training Policies: Monotonic Inference Policies as the Real Objective for LLM Reinforcement Learning
Tianjin University / AlibabaThis paper identifies a fundamental misalignment in LLM RL: improving the training-side policy does not guarantee improvements to the inference policy due to quantization and engine mismatch. The MIPI principle and MIPU framework address this with a two-step approach that filters policy updates via an inference-side gap proxy, improving reasoning accuracy and training stability on Qwen3 models under FP8 inference.
GigaWorld-1: A Roadmap to Build World Models for Robot Policy Evaluation
GigaAIGigaWorld-1 introduces WMBench, a benchmark for evaluating robot foundation models using world models as surrogate simulators. Through analysis of 7 video world models across 324,000 simulated rollouts, the study finds that long-horizon action-faithful rollout consistency matters more than short-term visual realism. Full code, models, and data are released publicly.
CompactionRL: Reinforcement Learning with Context Compaction for Long-Horizon Agents
Zhipu AI / Tsinghua UniversityCompactionRL addresses context-window limitations in long-horizon agentic RL by jointly training task execution and trajectory summarization. Using token-level loss normalization and cross-trajectory advantage estimation, it achieves 66.8% Pass@1 on SWE-Bench Verified (+7.0pp). The method was subsequently deployed in training GLM-5.2.

xAI Expands Grok Voice with 21 New Multilingual Flagship Voices
xAIxAI released 21 new flagship voices for Grok Voice on July 6, covering all 25+ supported languages for use cases including customer support, education, and entertainment. The original five Grok voices were also retrained for improved pacing and emphasis. The new voices are available via the Voice Agent API, Text-to-Speech API, and Voice Agent Builder.
Government of Alberta Uses Claude to Scan 466 Million Lines of Code for Vulnerabilities
AnthropicAnthropic published a case study showing how Alberta's Ministry of Technology deployed ~50 parallel Claude agents to scan 466 million lines of code in 20 hours — work estimated to take 6.5 years manually. The project also used Claude to generate fixes, write tests, and rebuild a Java portal in four days that originally took five months.
SWE-Together: Multi-Turn Benchmark for Coding Agent Evaluation
Togetherbench released SWE-Together (arXiv:2606.29957), a 109-task benchmark that replays real user-agent coding sessions using a reactive user simulator, measuring agents on both correctness and required user correction. Evaluation across Claude Code, Codex, OpenCode, and mini-swe-agent showed Claude Opus 4.8 achieving best pass@1 with fewest corrective interventions. Dataset and evaluation code are open-source at github.com/Togetherbench/SWE-Together.
Weak-to-Strong Generalization via Direct On-Policy Distillation
ByteDance / Tsinghua UniversityDirect-OPD transfers RL gains from smaller models to larger ones by treating the weak model's RL-induced log-ratio shift as a dense implicit reward signal for the student. Applied to Qwen3-1.7B, the method raises AIME 2024 accuracy from 48.3% to 62.4% in four hours of training without a separate reward model.
Claude Code v2.1.202 Released
AnthropicClaude Code v2.1.202 shipped on July 6, adding a Dynamic Workflow Size setting in /config and workflow.run_id/workflow.name OpenTelemetry attributes for tracing workflow-spawned agents. The release also fixes 12+ bugs including Ctrl+R history search crashes, background session rename reversion, and mTLS handshake failures, and reverts /review <pr> back to single-pass (multi-agent review now lives under /code-review <level> <pr#>).
OpenCode v1.17.14 Released with MCP Code-Mode Adapter
SSTOpenCode v1.17.14 shipped on July 6, adding a code-mode MCP adapter for running confined orchestration scripts against connected MCP tools. The release also fixes paginated MCP tool catalogs losing tool metadata, adds reopening for closed tabs and background tab opening, and overhauls the v2 review panel with session tab preview refinements.
OpenClaw v2026.7.1-beta.2 Adds GPT-5.6 Support and External Harness Attach
OpenClaw v2026.7.1-beta.2 (July 5) adds GPT-5.6 model-family recognition across catalog, capability, and runtime selection paths, and introduces 'openclaw attach' for launching an external harness against an existing Gateway session to support Codex-style resume-and-inspect workflows. The release also improves Telegram/Codex pairing flows and adds recovery across transient API failures.
