GitHub released Copilot Agent Plugins 1.0 into general availability today, pairing it with a redesigned CLI and multi-model switching built into the core product.

• Model portability is the explicit strategy: the update is architected so developers can swap underlying models mid-workflow rather than commit to one, a direct response to fragmentation across GPT-5.6, Claude, and Gemini variants.
• CLI redesign ships simultaneously, adding a tabbed interface and zero-config setup that reduces the friction cost of adopting the agent-mode features.

SentinelOne made its Purple AI Agentic Investigation capability available to all Singularity Platform customers today, offered as a complimentary trial with zero-click autonomous threat response.

• Zero-click investigation means Purple AI detects, investigates, verifies, and initiates response when a threat crosses a defined threshold, without waiting for analyst input — directly addressing SOC analyst capacity constraints.
• Timing is deliberate: the move comes as CrowdStrike and SentinelOne both hit 52-week stock highs last week on platform adoption momentum, and ahead of SentinelOne's August 28 earnings.

DeepSeek released DeepSeek Harness v0.1 in developer preview under the MIT license today, shipping an agent runtime where every component — model adapter, tool registry, session log, and control loop — is a replaceable plugin.

• Everything-is-a-plugin architecture means the harness is model-agnostic by design; enterprises can swap in any model without rewriting the orchestration layer, which is a direct threat to proprietary harness lock-in.
• 33,000 GitHub stars within hours of release signals the developer community is hungry for a vendor-neutral, open runtime — the same dynamic that made LiteLLM's proxy layer a de facto standard.

Gartner published research today predicting that AI inference costs per agentic workflow will increase more than fivefold through 2028, warning that falling token prices are masking rising total AI spend.

• The core argument: each successive generation of agentic products adds workflow steps and model calls faster than token efficiency improves, so cheaper tokens paradoxically fund more expensive total runs.
• Implication for product leaders: inference cost management — not feature parity — is now a primary margin variable, and organizations building agentic products on today's pricing assumptions will face a structural cost problem within 24 months.

Jamf Threat Labs today published research on AmnesiaStealer, a new macOS information-stealing malware that hijacks active browser sessions via remote control and spreads through ClickFix social engineering attacks using a counterfeit GitHub page with a forged Verified Publisher badge.

• The delivery mechanism is novel: the fake GitHub page is visually identical to the real one including the Verified Publisher badge, which bypasses user skepticism trained on obvious phishing indicators.
• Enterprise exposure is real: browser session hijacking without credential theft means the attacker inherits authenticated SaaS sessions — Okta, Salesforce, GitHub — without triggering password-based detections.
