The llm-gemini 0.33 plugin was released with support for the Gemini 3.7 Flash release and related model variants. It adds compatibility with LLM 0.32 and includes a server-side tools example using gemini-3.7-flash with CodeExecution to run a Python factorial calculation of 13. As a result, reasoning traces can be viewed and server-side tools can be enabled, but a Safari-rendering issue can make the pelican SVG missing in Firefox and Chrome.

Microsoft will stop showing Mico, Copilot’s emotive yellow avatar, when users use the chatbot’s voice mode. The change moves Mico to the Learn Live platform, and Mico was launched in Copilot’s voice mode in October 2024. Going forward, Mico will appear on Learn Live instead of in Copilot voice interactions, with the avatar having more reactions there.

DeepSeek open sourced DeepSeek Harness, a Node.js agent runtime that treats the model adapter, tool registry, session log, and agent loop as interchangeable plugins. Within a few hours of going live on GitHub, the repository received more than 33,000 stars. Developers can now build and extend agents by mounting plugins rather than patching a privileged core, with features driven by an append-only session event log.

AI application teams discover that production costs rise sharply because token-heavy architectures keep sending unnecessary text even when the model itself works as expected. The article cites prompt caching that can cut costs by up to 90% by reusing static prefix attention computations. As a result, developers are pushed to apply architectural token optimization (prompt caching, semantic caching, history summarization, retrieval/tool trimming, and routing) instead of only switching to cheaper models.

Deep Learning Weekly compiled this week’s deep-learning updates, including AI model releases, agent and evaluation tooling, and new research papers. The BDH-CQ paper reports a 150M-parameter setup achieving 29.5% pass@2 at a computed inference cost of $0.0007 per task. The roundup changes by giving readers a curated set of concrete releases, benchmarks, and measurements to track rather than any single narrative development.

Code review is shifting from catching bugs to guiding product decisions, knowledge sharing, and judgment as AI-generated code increases review volume. The article cites a potential split where review feedback is divided into 45/30/25 buckets after sorting the last 1000 comments. Teams are likely to move review toward intent before code is written and to automate repeatable standards with rule-based enforcement, making “code review” less about diffs and more about organizational decision-making.

GhostWriter by MyHandler launched and lets users double-tap Ctrl in any text field to generate a reply based on on-screen context and personal data. The key interaction is two taps of the Left Ctrl in any text field. It types a suggested message into the box but never sends, with help from an encrypted vault on the PC and checks to avoid double-booking.

Mindgard, a Lancaster University spinout, raised a $30M Series A after disclosing vulnerabilities including a zero-day in Cursor and bypasses of ChatGPT and Google guardrails. The round brings its total funding to nearly $42M. Mindgard will use the money to expand product development and sales as AI security consolidates and it competes as an independent offensive red-teaming platform provider.

Deepmark is a bookmarking tool that uses AI to search bookmarks based on their content rather than just titles or URLs. The system indexes and analyzes the actual text within bookmarked pages to enable semantic search. Users can now find saved content through natural language queries about what the pages contain, improving discoverability of their bookmark collections.

For all the talk of AI agents that can browse, plan, and finish the job, today’s reality check is on the web itself. Users of Meta’s Muse, xAI’s Grok, OpenAI’s Dots, and Instinct have reported being blocked when agents try to take actions at major sites—turning “autonomous” into “ask permission.” The practical fix is emerging in parallel: Perplexity open-sourced SPACE, its Firecracker microVM sandbox for running agent tasks, and said median create latency fell from 185 ms to 60 ms while host-escape mitigations hit 0 of 108 red-team runs. In other words, the stack is getting more careful about where code runs and what it can do, because the outside world is increasingly saying no.
