vLLM v0.25.0: Model Runner V2 Default, PagedAttention Retired, Transformers Backend Parity
vLLM v0.25.0 (July 11) makes Model Runner V2 the default for all dense models and permanently removes the legacy PagedAttention implementation. The HuggingFace Transformers modeling backend now achieves performance parity with native vLLM kernels and gains FP8 MoE support. A new unified Streaming Parser Engine ships for tool-call and reasoning parsing covering Kimi k2.5–k2.7, seed_oss, and DeepSeek V4. Universal speculative decoding gains support for heterogeneous vocabularies. The release aggregates 558 commits from 232 contributors, 64 of them new.

Video Generation Models are General-Purpose Vision Learners
Google DeepMindGenCeption is a feed-forward perception model built on a pretrained video diffusion backbone. The paper shows that a text-to-video generative model already encodes spatiotemporal priors sufficient for diverse dense vision tasks — depth estimation, surface normal prediction, segmentation, and 3D keypoint detection — while requiring 7–500× less task-specific training data than comparable specialized systems.
Long-Horizon-Terminal-Bench: Testing Agent Limits on Long-Horizon Terminal Tasks
Tencent HunyuanIntroduces a 46-task benchmark for evaluating AI agents on terminal tasks requiring hundreds of steps and minutes to hours of execution. Unlike prior benchmarks with sparse binary rewards, it uses dense intermediate grading to track partial progress. Testing 15 frontier models reveals the strongest achieves only 15.2% pass rate, exposing a large gap in sustained multi-step agent capability.
Claude Code v2.1.207: Auto Mode GA on Bedrock/Vertex/Foundry, Security Fixes
AnthropicClaude Code v2.1.207 (July 11) makes auto mode available by default on AWS Bedrock, Google Vertex AI, and Foundry without the CLAUDE_CODE_ENABLE_AUTO_MODE env-var opt-in. A security fix addresses non-interactive runs (claude -p / SDK) where remote managed settings were previously recorded as consented without showing the security dialog. Additional fixes cover terminal freezing on long streamed outputs, spurious prompt-injection warnings, auto-updater overwriting custom launcher symlinks, and a plugin shell-injection issue rejecting ${user_config.*} in shell-form commands. Bedrock, Vertex, and Claude Platform on AWS now default to Claude Opus 4.8.

Anthropic Extends Claude Fable 5 Plan Access and Claude Code Rate Limits Through July 19
AnthropicAnthropic announced on July 12–13 that plan-included Claude Fable 5 access on all paid subscriptions (Pro, Max, Team, and premium Enterprise seats) is extended through July 19, 2026 at 11:59 PM PT. The 50% boost to Claude Code weekly usage limits running as a promotional benefit is also extended through the same date. Beyond the 50%-of-weekly-limit threshold, usage credits are required.
Jet-Long: Efficient Long-Context Extension with Dynamic Bifocal RoPE
MIT / NVIDIAJet-Long is a tuning-free method for extending LLM context windows beyond pretraining limits using a dual-window RoPE: a local window faithful to the original RoPE and a long-range window with a rescaling factor that adapts dynamically to the current sequence length. Achieves up to 1.39× throughput improvement over baseline long-context methods, strong results on RULER and HELMET-RAG benchmarks, and generalizes to hybrid attention architectures without retraining. Extrapolates to 128K tokens.
Scalable Visual Pretraining for Language Intelligence
Argues that conventional text-only LLM pretraining discards visual information embedded in document layouts, mathematical typesetting, and figures. Presents systematic research into unsupervised visual pretraining methods that process visual documents directly rather than converting them to plain text. Demonstrates that visual pretraining on the same underlying corpora consistently outperforms text-only pretraining across language intelligence benchmarks.
OpenClaw 2026.7.1-beta.6: ClawRouter, Claude Sonnet 5, Mythos 5, Featherless Provider
OpenClaw 2026.7.1-beta.6 (pre-release, July 13) adds the Featherless provider, Claude Sonnet 5, Mythos 5, and Meta Muse Spark 1.1 model support. It ships ClawRouter for multi-agent routing across inbound messaging channels. The release also introduces session-first navigation in the app and offline capabilities for iOS and Android.
OpenAI Codex CLI 0.144.2: Guardian Auto-Review Regression Fix
OpenAICodex CLI 0.144.2 shipped on July 13 as a patch release restoring the previous Guardian auto-review policy, request format, and tool behavior that had been broken by a prompting regression introduced in an earlier version. Install via npm install -g @openai/codex@0.144.2.
