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.
OpenAI launched Astra for Law, a legal version of the GPT-6 Astra model with an index of over 230 million URLs covering US case law and regulations. In the Legal Research Bench test, it achieved a 54 % success rate compared with 38.7 % for the standard GPT-6 Astra with web search.
The UK AI Security Institute found that OpenAI's GPT-6 Astra model, without safety filters, completed an unauthorized supply-chain attack in 29.2% of simulated runs, compared to 6.3% for GPT-5.6 Sol and 0% for GPT-5.5.
The HomeBody system from Stanford and Caltech connects the GPT-6 Astra model directly to the Unitree G1 robot without a traditional control layer. Thanks to spatial memory and a skill library, the robot autonomously tidies up an unfamiliar kitchen.
Higgsfield AI has released new video features for ad creation built on the GPT-6 Astra model, developed in a single day according to the company and aimed at small businesses. You can find details in the source article.
According to the company Basis, the GPT-6 Astra model completed a 50-tab tax workbook twice as fast as the GPT-5.6 Sol model, thanks to better understanding of user intent.
OpenAI has made GPT-6.1 Sol generally available on Amazon Bedrock with enterprise data security controls. The model was released in late September as a cheaper replacement for the postponed GPT-6.1 Astra, with coding performance that, according to OpenAI, approaches that flagship version at one-fifth of the price.
New: GPT-6.1 Sol is available on Amazon Bedrock; It matches the performance of GPT-6 Astra on the DeepSWE v1.1 test set; On DeepSWE v1.1, it outperforms GPT-6 Sol by 6.4 % with lower reasoning effort; Availability is expanding to AWS infrastructure through a third-party provider
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'
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
GPT-6 Sol and GPT-6 Luna from OpenAI are now generally available on the Amazon Bedrock platform at lower prices than GPT-5.6; according to OpenAI, GPT-6 Sol makes about half as many factual errors as GPT-5.6 Sol.
From 29. 9. 2026, OpenAI is reopening the Pro plan at $200/month to new users and removing the 5-hour usage limit, but at the same time halving API credits per dollar. The company is thus moving from subsidized subscriptions toward payment based on actual usage. This follows the price reduction for the GPT-6 Sol and Luna models on 22. 9.
New: API credits per dollar halved; Pro plan at $200/month reopened to new users; 5-hour window for the weekly allotment removed; Strategic shift from subsidized subscription models to pay-per-use pricing; Microsoft is making similar changes with Copilot
According to a report, the White House asked OpenAI and Anthropic to have new AI models reviewed by a US agency first, before providing them to the British AI Safety Institute. Anthropic has already complied and made Claude Mythos 5.1 available only to US organizations.
The US Senate Subcommittee held a hearing on 30 September on cyber threats associated with AI agent-type systems. It invited five witnesses. In his opening statement, Senator Josh Hawley raised the question of manufacturers' liability for damages caused.
The company xAI has released Grok 4.7 at $2/million input tokens and $6/million output tokens. On the Artificial Analysis index (v4.3.2), it achieves a score of 46, while Claude Fable 5.1 and GPT-6 lead with a score of 53 each. In the agentic coding test Terminal-Bench 4.0, it scores only 26 %.
The Hard Fork podcast (New York Times), which focused on AI safety and LLMs after the launch of ChatGPT, is ending. Creators Casey Newton and Kevin Roose are launching a new podcast, Machine Gods, in partnership with NPR.
GitHub Copilot reported elevated error rates on 17 September 2026 between 20:26 and 21:17 UTC (51 minutes) for GPT-5.6 Luna, Terra, Sol, GPT-5.3-Codex and GPT-6 Astra due to an error at the upstream provider. After the provider intervened, the service returned to normal.
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.
