WithEveryone Generates Group Portraits of Up to Ten People by Binding Identities to Layouts, but Weights Remain Unavailable

A team from Tencent Hunyuan and Fudan University has introduced WithEveryone, which first binds each reference person to a structured layout and then supervises generation using a regionalized identity loss. In the authors’ identity-disjoint evaluation, it improves subject coverage and reduces copy-and-paste artifacts, but the license of the existing base model prevents the team from releasing the research-version weights.

Five Frontier AI Labs Score No Higher Than C+ on Controls, With Model Containment Plans the Biggest Public Gap

Guidelight assessed Anthropic, Google, Meta, OpenAI, and xAI against six actionable control measures. No company came close to full implementation in any category. The scores reflect only publicly available evidence as of August 18; a low score does not necessarily mean that the relevant internal mechanisms do not exist.

Faraday Uses a 27B Outer-Layer Agent to Orchestrate GPT-5.5, Outperforming Standalone Frontier Models on Paper-Figure Reproduction Benchmark

Inherent has unveiled Faraday, trained with long-horizon reinforcement learning, which puts a 27B model in charge of research decisions while delegating programming work to GPT-5.5. It outperforms Claude Opus 4.8 and GPT-5.5 on Replica’s held-out set, but the results should not be interpreted as showing that the 27B model alone surpasses frontier models.

Anonymous Model Ox Alpha Offers a Free 1M Context Window, but the Provider Retains Prompts and Outputs

Ox Alpha has sparked a wave of testing on OpenRouter and OpenCode with its free access, long context window, and multimodal agent interface. OpenRouter’s current page explicitly states that the anonymous provider retains prompts and completions, making early claims of “zero data retention” unsuitable as a basis for production use.

GPT-5.6 Sol Temporarily Drops to $20 per Million Output Tokens, While Entire Requests With Ultra-Long Prompts Still Incur Higher Rates

OpenAI has cut GPT-5.6 Sol API input and output prices by 20% and 33%, respectively, with the promotional rates lasting at least through November 21. Once input exceeds 272K tokens, the higher rates still apply to the entire request, so long-context agent costs cannot be estimated from standard rates alone.

Cline SDK 0.0.78 Preserves Agent Work Through Event Replay; Unpinned Models May Switch to New Defaults

Cline has added draining, a persistent event log, and a run queue to the Hub, preventing agent work from being lost during upgrades or reconnections. The release also fixes a bug that silently removed all tools from custom OpenAI-compatible models, while catalog updates have changed the default models for some providers.

Cloudflare API MCP Adopts Optional OAuth Scopes, Letting Agents Narrow Permissions to What Each Task Requires

Wrangler and Cloudflare API MCP Server now allow users to reject unnecessary scopes during authorization instead of requiring them to accept all requested permissions. Required scopes still cannot be deselected, and tool calls lacking the necessary scope can run only after reauthorization.

MidTool Releases 20.3B-Token Tool Mid-Training Dataset; 4B and 8B Models Improve Across Three Agent Benchmarks

MidTool places APIs, MCP, documentation, code, and synthetic workflows in a dedicated stage after pretraining and before SFT. The dataset and model checkpoints are now public, but the models still score zero on deep-search evaluations, showing that learning schemas is not the same as acquiring long-horizon research capabilities.

Claude Security Integrates Mythos 5, Replacing Direct Model Access With Restricted Scan Results

Enterprise customers can now use Mythos 5 to scan code repositories and receive CWE classifications, severity levels, confidence ratings, and recommended fixes. The model remains behind a controlled service, and fixes require human review, but Anthropic has not disclosed detection accuracy.

NVIDIA AVO Solves All 183 Levels in the ARC-AGI-3 Public Set, With Key Gains Coming From the Agent Framework Rather Than a Model Change

Using persistent memory, a supervisor agent, and a text-grid interface, AVO enabled Claude Opus 5 to complete every public level within 6,624 environment actions. The score of 100 covers only the public set and should not be interpreted as passing the semi-private or private competition tests.

Claude Code 2.1.239 Tightens Cloud Agent Egress and Fixes Bedrock Streaming Retries That Caused Double Billing

The new release forces some Claude Code web tool requests through the session network proxy and also fixes issues involving proxied environments, MCP reconnections, and sensitive input handling. It adds a Python SDK migration command, but Anthropic has not disclosed the vulnerabilities’ severity or the scale of impact.

4DAnyone Releases Model and Inference Code, Expanding Monocular Human Videos into Up to 48 Reconstructed Views

The system uses a fixed-length reference context and view regrouping during diffusion to reduce structural drift when generating multiview videos in batches. The weights and inference pipeline are now public, but the fully open-source 4D Gaussian Splatting reconstruction and low-memory mode are not yet complete.
