Anthropic, together with AWS, has made Claude Opus 5.5 available on Amazon Bedrock – according to the company, it is more efficient and cheaper per task than Claude Opus 5, with adaptive thinking and stricter safety classifiers.
The Claude Opus 5.5 model from Anthropic is now available in GitHub Copilot for Pro+, Max, Business and Enterprise plans. According to Anthropic, it handles tasks comparably to Opus 5, but with fewer steps and tokens.
Since 23 September 2026, Amazon Web Services has been making a biological AI model from The Biological Computing Company available to selected customers in limited testing. According to the manufacturer, the model mimics how brain cells process information and is intended to make video generation faster and cheaper.
The Austrian Academy of Sciences, together with Mistral and Sail Reply, is releasing the Apollo model, trained on 600 million words of ancient Greek. It fills in missing passages in damaged papyri and manuscripts and is available free through a chatbot for academics, but the final choice of words remains with experts.
OpenAI released the GPT-6 Sol and Luna models on 22 September 2026 at prices 50% lower than GPT-5.6 (Sol 2/10 USD, Luna 0.10/0.50 USD per million tokens). However, an independent analysis by Artificial Analysis shows that actual capabilities remain at the level of their predecessors and have even declined on some tasks.
New: Anthropic released Claude Opus 5.5 on the same day (2026-09-23), roughly an hour after OpenAI; Claude Opus 5.5 is 20% cheaper than the previous Opus 5.0 ($4/$20 vs $5/$25); Opus 5.5 improved communication style and token efficiency; The model releases launch a 'price war' between the two largest AI companies; GPT-6 Luna and Sol are part of a broader strategy of price competition, not an isolated release
According to estimates from Apptopia, in its first 12 days the Muse app from Meta had more downloads (1.8 million on iOS in the USA/Canada vs. 1.3 million for ChatGPT) and daily active users (642 000 vs. 231 000 in the USA) than ChatGPT in the comparable period.

Microsoft Research published the RetroChimera model in Nature, a combination of the transformer model R-SMILES 2 and the graph network NeuralLoc for predicting molecular retrosynthesis. According to the company, chemists in blind tests prefer its synthesis proposals over older methods. The model is on GitHub under the MIT license and…
Grok 4.7 from xAI is gradually becoming available in GitHub Copilot for all paid tiers (Pro, Pro+, Max, Business, Enterprise), billed at the provider's list prices.
TypeSafe AI clarified the price of Jev (0.042 USD/million input tokens, output free), and commentators point to the risk of hidden bias and the absence of explanations for decisions in this classification model with no text output.
New: Model price: $0.042 per million input tokens, output free; Risk of hidden bias in the classification model; The model operates as a black box without explaining its decisions; Applicable to spam filtering and search reranking; TypeSafe AI categorizes it as 'System One models'
Skild AI has deployed the S1 model at NVIDIA's factory in Houston, where, together with partner Foxconn, it helps assemble systems with Blackwell GPUs, and has announced annual revenue of $100 million. The model was previously introduced as a system that learns new tasks from a single video.

To accompany the release of the open model Muse Glimmer (30B, Apache 2.0), Meta published an extensive essay by Mark Zuckerberg defending distillation and its open strategy against OpenAI and Anthropic; it also promised to open the weights of Muse Spark 1.2.
New: Mark Zuckerberg published an essay (6000+ words) on AI philosophy, governance and the strategy of Meta; The announcement includes Muse Code, an AI agent for the terminal; Meta strategically positions open-weight models as an alternative to proprietary approaches from OpenAI and Anthropic; The essay criticizes lobbying by competitors and mentions competition from Chinese open-weight models; The new strategy of Meta focuses on differentiation through an open-source approach
According to sources familiar with the matter, ByteDance is training an AI model with up to 10 quintillion parameters — three times as many as Kimi K3 from Moonshot. It is in an early stage of pretraining; the estimated size of Mythos 5 from Anthropic is around 8 quintillion parameters.
Kimi K3 (2.8 trillion parameters) from Moonshot AI has also been available on the Amazon Bedrock platform since 18 September 2026, with support for prompt caching and AWS data protection. The model was released in July 2026 as the first open model in the 3 trillion parameter class.
New: Kimi K3 is now available on Amazon Bedrock as a new distribution channel; The model supports prompt caching on Bedrock; Data in AWS Bedrock is protected by the AWS data boundary without being shared with the provider; The Bedrock deployment optimizes the model for long coding and knowledge workflows
Anthropic has released Claude Opus 5 at the same price as Opus 4.8 (5 USD/25 USD per million tokens), which the company says is half the price of Fable 5. It leads in agentic coding and ARC-AGI-3, while lagging in cyber exploitation and some domains such as healthcare and law.
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.
