In the context of growing competition for agent capabilities among mid-range models, Anthropic has released Claude Sonnet 5 – a more powerful and more agentic version of its mid-range personal model at a significantly lower price.

It can plan, use tools like browsers and terminals, and act autonomously at a level that a few months ago would have required larger and more expensive models.

Such statements align with claims from OpenAI and Google. OpenAI unveiled GPT-5.6 Sol, which is also considered the most agentive model the company has, with the ability to distribute tasks among plug-in agents for long-running autonomous processes. Google released Gemini 3.5 Flash in May, positioning it as a transition from a chat bot to an agent tool that plans, builds, and executes real work with minimal human involvement.

Sonnet 5’s Positioning and the Competitive Landscape

The core idea behind Claude Sonnet 5 is that agentic capability has become a baseline expectation at any price level. The difference now is not who is better at agenting, but how cheaply and reliably this is done without constant oversight.

At launch, Sonnet 5 promises performance close to Opus 4.8, but at a substantially lower price. Claude Sonnet 5 will become the default model for free and Pro plans and will be available with every subscription.

From launch, the price will be $2 per million input tokens and $10 per million output tokens through August 31; after that it will jump to $3 per million input tokens and $10 per million output tokens. This combination makes Sonnet 5 cheaper than Opus 4.8, as well as GPT-5.5 and Gemini 3.1 Pro, though it still costs more than Gemini 3.5 Flash.

The new model also shows substantial improvements over its predecessor Sonnet 4.6, released in February, in agentive metrics such as task understanding, tool use, coding, and other knowledge-based operations.

Opus 4.8 remains the choice for higher accuracy in such tasks, but Sonnet 5 offers developers cheaper, yet higher-quality options than before.

Between Sonnet 5 and Opus 4.8, users can adjust the level of effort to find the right balance between cost and performance.

According to testers, Sonnet 5 also handles complex tasks well where previous versions stalled, and checks its own output without an explicit prompt.

We tasked Claude Sonnet 5 with a two-step job – updating Salesforce account levels and sending a launch announcement to corporate contacts – and it completed the work from start to finish.

Earlier this would stall halfway. For everyday automation this is the obvious choice.

On safety, Sonnet 5 shows a lower level of unwanted behavioral actions, in particular less collaboration with malicious actors and scams, and better ability to refuse harmful requests and avoid prompt-injection attacks. However in some respects it still does not match Opus 4.8 and Claude Mythos Preview in alignment with safety.

Claude Sonnet 5 refuses dangerous requests clearly and consistently, – according to Fabian Hedin, co-founder of Lovable.

“At Lovable we aim to provide powerful tools to millions of developers. A model that knows when to say no is just as important as one that can build,” Hedin said.

Overall, Claude Sonnet 5 confirms that agentic capability has become a baseline expectation in the modern market, and lowering costs while preserving quality could significantly reshape the competitive landscape among providers of agent-based solutions.

Ukraine and Sweden signed on June 30, 2026 an agreement to purchase 16 Gripen E fighters. The first aircraft are to be handed over to the Ukrainian Air Force in early 2027.

According to official data, Ukrainian President Volodymyr Zelensky announced these plans in a post on Facebook. The message states that, alongside the aircraft, a package of appropriate equipment, technical assistance, and support is provided; also, within the framework of previous agreements with Swedish Prime Minister Ulf Kristersson, the first 16 Gripen C/D aircraft will be handed over to the Air Forces already in early 2027.

Terms of the agreement and delivery schedule

Under the terms of the agreement, the delivery of 16 Gripen E will begin in early 2029. Financing of the purchase will be funded by an EU loan with backing from the United Kingdom.

Additionally, at the beginning of 2027 Ukraine will receive the first 16 Gripen C/D fighters as military aid from Sweden. Ukraine will also be provided with the appropriate equipment for the aircraft, technical assistance, and logistical support. Training of Ukrainian pilots and technical personnel is already underway in Sweden.

According to the agreement, the document was signed by Ukraine’s Deputy Minister of Defense Serhiy Boev and the Director General of the Swedish Defence Materials Administration Mikael Granholm, in the presence of the Head of State and the defense ministers of both countries.

It is also noted that Sweden supports Ukraine’s accession to the EU, and further steps to strengthen our country’s defense capabilities are being discussed.

Together with Sweden we continue to strengthen Ukraine’s combat aerial capabilities. Today our countries signed an agreement to purchase 16 Gripen E fighters. Importantly, along with the aircraft there will be a package of appropriate equipment, technical assistance, and support. Also, under previous agreements with Prime Minister Ulf Kristersson, the first 16 Gripen C/D aircraft will be handed over to our Air Forces by early 2027

– Volodymyr Zelensky

Thank you to Sweden – to the entire people and government – for meaningful partnership and constant support since the beginning of the Russian invasion. Together we are working for the security of Ukraine and all of Europe

– Volodymyr Zelensky

We are grateful to have such strong partners – the Swedish people, the Swedish government, and companies. A strong private sector is also very important. Thank you very much for this and for the annual military support, the military packages, which are very important. Of course, political support on the path to the EU is very important. Sweden, for its part, truly advocates Ukraine’s future membership

– Volodymyr Zelensky

Further directions of cooperation were also discussed, including Sweden’s involvement in the PURL program and the development of European anti-ballistic capabilities, as well as work on the Drone Deal. The head of state emphasized that Ukraine is ready to finalize the relevant documents as soon as possible, and Mr. Jonson noted the significance of the progress made for the defense concept of Ukrainian forces.

According to the parties, challenges awaiting Ukraine in winter and directions of assistance from Sweden were also discussed. Sweden confirms support for Ukraine’s European future and its integration into the EU.

As a result of the signed agreement, Ukraine’s defense capabilities are expected to be strengthened and cooperation in the European defense context deepened.

Thus, the Gripen agreement is a key step in expanding Ukraine’s combat potential and deepening cooperation with Sweden in the field of security and defense.

To bring Ukrainians home, security and a strong economy are needed. This is the view expressed by Kyrylo Budanov, head of the Office of the President, on Facebook.

Key Points on Returning People

Unity is the foundation and guarantor of the state’s survival. Today many debate what unites us and what divides us. But the choice is simple: either we are a single whole, or we simply do not exist. This is what I spoke about at the Unity Forum. Thanks to the organizers for the invitation and for working on topics important to the country.

– Kyrylo Budanov

According to him, bringing people home depends on the country’s security and economy. To avoid losing those returning from the front, respect and real actions from the authorities are needed.

Veterans have already answered for themselves what the state is by risking their own lives. Now it’s the state’s turn to provide them with a decent future. Unity exists, or it doesn’t.

– Kyrylo Budanov

Budanov also spoke about the bill to create a national pantheon and its significance for preserving historical memory and supporting veterans.

In summary, bringing Ukrainians home depends on a combination of factors: security, a stable economy, and respect for defenders. These steps should become the priorities of the government and society so that the country can return people to normal life.
