Code review in the GitHub Copilot code review service can now be requested via the REST API and GraphQL API with a custom effort level for each request. Starting 28 September 2026, the default option uses the Balanced level; an explicitly set Lite level remains unchanged.
The AstaBrief 8B model generates scientific reports with citations and is available in the Fast mode of the Asta service. The authors are releasing both the weights and the training data. According to their measurements, the entire process takes an average of 51.1 seconds compared to 178.5 seconds in Thinking mode.
According to NVIDIA, a variant of the NVIDIA DGX Spark with 64 GB unified memory will be available this month from partner manufacturers. The text mentions the company Acer, but does not state the price or a specific sales start date.
The Live Data in Apps feature allows Amazon Quick applications to query Amazon Quick Sight datasets every time they are opened. According to AWS, the queries are executed with the user's permissions and respect row-level and column-level access restrictions.
The computer use feature is in public preview in the GitHub Copilot CLI and GitHub Copilot app tools for macOS and Windows. According to GitHub, it allows control of desktop applications. It requires user consent, and organizations can disable it.
The automations feature in GitHub Copilot in the VS Code editor allows running agent tasks hourly, daily, weekly, or on demand. A task definition can be created from a template or using a custom prompt. The feature is available in preview.
Part of an overview of multiple AI topics; only this event has been covered.
The dynamic workflows feature is available in public preview in Copilot CLI, GitHub Copilot app, and GitHub Copilot SDK on all GitHub Copilot plans. It allows defining sequential and concurrent steps and agent involvement in code.
The HydraFusion research preview is now available in Visual Studio Code and the GitHub Copilot app. It coordinates multiple models and supports the Copilot Pro, Pro+, Business, and Enterprise plans. Company access requires an admin to enable preview features.
Starting October 5, OpenAI is introducing three API usage tiers instead of the previous five: Build, Launch, and Grow. Organizations are moved to a higher tier automatically based on the total volume of credits purchased.
NVIDIA has released the open foundation model Kumo Tabular (28–215M parameters) for classification and regression on tabular data. According to the company, the model predicts without training, tuning, or feature engineering, and leads on the TabArena, BeyondArena, TALENT, and ScoringBench benchmarks.
OpenAI has added a new "ultrafast" service tier to the Responses API for the GPT-6 Astra model, which reduces latency between generated output tokens. The feature does not support EU or other regional data residency.
The company xAI has introduced Grok 4.7 on Amazon Bedrock: a context window of 500 000 tokens and four reasoning effort levels. According to Artificial Analysis, performance on agentic tasks and knowledge work improves compared with Grok 4.6, but at roughly twice the token consumption.
The Claude Sonnet 5.5 model is available on Amazon Bedrock and in Claude Platform on AWS – according to AWS, a cheaper and faster option for well-defined tasks such as bug fixes, SQL generation, or UI testing.
The new family of open-source agentic models Holo4 (27B dense, 35B-A3B MoE) handles GUI control, writing and running code, MCP, and API all in one model. On OSWorld 2.0, Holo4-27B achieves 61.7% compared to 81.8% for the Opus 5.5 model, but at significantly lower cost.
The Claude Sonnet 5.5 model has been released with the identifier claude-sonnet-5-5. It is available via the Claude API as well as in the offerings of Amazon Bedrock, Claude Platform on AWS, Google Cloud, and Microsoft Foundry.
GitHub has added an in-product validator to GitHub Copilot that checks enterprise managed settings configuration files – it detects malformed JSON, unsupported settings, and invalid team mappings.
The GitHub Copilot usage metrics API has a new field, pull_request_review_times, which shows the median and 90th percentile duration of three pull request review phases – for enterprises and organizations with the metrics policy enabled.
Agentic autofix in GitHub Copilot now, according to GitHub, uses Copilot Memory – it stores security alert fix patterns and shares them with other Copilot features. Both features are in public preview.
GitHub has launched a public preview update to GitHub Copilot for Slack and Microsoft Teams with improved use of conversation context, model switching, and linking to GitHub issues. Available for Business and Enterprise plans, gradual rollout.
OpenAI has fixed a bug in image encoding in the GPT-6 Sol and GPT-6 Luna models that was degrading visual input understanding in both the API and the Codex product. The company recommends re-verifying affected workflows.
Liquid AI has released the draft model LFM2.5-VL-DSpark (280M parameters) for speculative decoding with the LFM2.5-VL-3B model. According to the company, it speeds up decoding by up to 3.13× on-device and up to 2.66× on the H100, with day-one support in llama.cpp, MLX-VLM and SGLang.
Compliance API local session endpoints for Claude for Microsoft 365 (Excel, PowerPoint, Word, Outlook) have moved from beta to full availability (GA), Anthropic announced.
Anthropic is once again billing for refused requests in the Claude API in the bio, frontier_llm, and reasoning_extraction categories when the refusal occurs before any output – it is billed at the same rate as a regular request.
The Compliance API in the Claude product has stopped returning file names, project document names, and artifact titles in the Activity Feed, including retroactively. A name can now only be looked up by ID via a Compliance Access Key with the read:compliance_user_data permission.
AI Radar monitors Czech and international sources every day, looking for changes that truly deserve attention.
The result is a quick overview of what has actually changed in the AI world, rather than another stream of articles.
Use the CS/EN switch to read the same Radar in Czech or English. English content is published after its translation has been checked, so new and older items may appear later.
Each row represents one event — not one article. At a glance, you can see its significance, credibility and main point.
Illustrative example, not a current news item.
Agent mode is available to all paying users
Until now, the mode was available only on the highest plan; it is now available on all paid tiers without a waitlist.
The detail page contains a fuller summary, its significance and original sources. Practical impact appears in the detail and the For individuals and For businesses views. An AI Flash item reaches the main selection only after it has been expanded and meets the publication rules.
We first summarize each event in the same way for everyone. Based on those same facts, we then explain what the change means for your own use and what it could mean for how a company operates.
Today’s briefing is the same for everyone. Pages For individuals and For businesses can be found in the main navigation — they select only events relevant to the given use case.
