We are generating a weekly news digest about AI agent startups for the week of 2025-06-30 to 2025-07-08. The output must be in JSON format with two fields: "shortSummary" and "longSummary". The summaries should be written at a 5th-grade reading level, and we must not include the date range in the text.

Steps:
1. Identify relevant news from the search results within the specified week.
2. Focus on AI agents or agentic AI startups.
3. Since readers are worldwide, mention country names when something is country-specific.
4. Write in an article style, split into multiple paragraphs for easy reading.
5. For the JSON structure:
   - "shortSummary": 300-500 words, multiple paragraphs, inline citations (e.g., [1]), and key phrases in bold.
   - "longSummary": 800-1200 words, multiple paragraphs (each covering a different aspect), examples, inline citations, and key phrases in bold.

Search results analysis:
- [1] from 2025-06-24: Lists top 10 AI startups of 2025, including Anthropic, Decagon, Cohere, AI Squared, Morphos AI, Writer, etc. They are leading in GenAI, automation, LLMs, and agentic AI. Mentions that Gartner expects generative AI spending to reach $644B in 2025. [Note: This is from June 24, which is before our week, but it's about the hottest startups so far in 2025 and is still relevant for the weekly update as it sets the context.]
- [2] from 2025-07-01: PRNewswire release about MarketsandMarkets recognizing top AI agents startups/SMEs, including Leena AI, CUJO AI, Tars, and LawGeex. Highlights Leena AI's platform for employee self-service that reduces ticket volume by up to 70%.
- [3] from 2025-06-24: Lists top AI startups in 2025. Features xAI (Elon Musk's) with Grok-3, located in New York. Also mentions JusBrasil in Brazil, which has an AI feature for legal research. [Note: June 24 is before our week, but the content is about top startups in 2025 and is relevant.]
- [4] from 2025-07-06: YouTube video transcript snippet. Mentions Grok 3.5 cancelled and Grok-4 coming in July, and Deep Agent from Abacus AI. Also notes that Hugging Face shut down Hugging Chat. [This is within the week and directly relevant.]

Relevant news for the week (2025-06-30 to 2025-07-08):
- From [2] (July 1): MarketsandMarkets recognizes top AI agents startups, including Leena AI, CUJO AI, Tars, and LawGeex.
- From [4] (July 6): 
  - Grok 3.5 cancelled, Grok-4 coming in July (from xAI, Elon Musk's company).
  - Hugging Face shut down Hugging Chat.
  - Deep Agent from Abacus AI, which is a highly capable AI agent.

We also have background from [1] and [3] about top startups, which we can use for context but must cite appropriately.

Plan for the summaries:
Short Summary (300-500 words):
- Start with an overview of the week in AI agent startups.
- Then, cover the key events: the recognition of top startups by MarketsandMarkets, the developments at xAI (Grok-4), Hugging Face shutting down Hugging Chat, and the launch of Deep Agent by Abacus AI.
- Use multiple paragraphs, each covering one major point.
- Include citations: [2] for MarketsandMarkets, [4] for xAI, Hugging Face, and Abacus AI.
- Bold key phrases like "agentic AI", "Grok-4", etc.

Long Summary (800-1200 words):
- Break into multiple paragraphs, each covering a different aspect.
  - Paragraph 1: Introduction to the week's AI agent landscape.
  - Paragraph 2: Details on the MarketsandMarkets report and the top startups recognized (Leena AI, CUJO AI, etc.). Include specifics about Leena AI's platform and impact.
  - Paragraph 3: News from xAI (Grok-4) and the cancellation of Grok 3.5. Mention the company's background and location (New York).
  - Paragraph 4: Hugging Face shutting down Hugging Chat and its implications.
  - Paragraph 5: Deep Agent by Abacus AI, describing its capabilities and why it's significant.
  - Paragraph 6: Background on other top AI startups (from [1] and [3]) to provide context, but we must note that these are not new from this week but are relevant to the overall topic.
- Include examples and cite appropriately.

Note: Since [1] and [3] are from before the week, we must be careful to use them only for background and not as breaking news. The breaking news are from [2] and [4].

Word count management:
- Short summary: Aim for 300-500 words. We'll write concisely.
- Long summary: Aim for 800-1200 words. We'll go into more detail.

Writing style: 5th-grade reading level. Use simple words, short sentences, and clear explanations.

JSON Structure:
- The output must be exactly in the specified JSON structure, with double newlines (U+000A) as actual newlines in the JSON string (which in JSON must be escaped as \n). However, note that in JSON, newlines in string values are represented as \n. But the instruction says: "escape new line characters (Use actual newlines (U+000A), but escape them correctly for JSON output)". This means that in the JSON string, we use the escape sequence \n for newlines. Alternatively, we can write the string with actual newlines and then escape them when writing the JSON. However, to be safe, we will generate the string with newlines and then use the standard JSON escaping (which uses \n). In practice, when we write the JSON, we will represent a newline as the two-character sequence: backslash followed by 'n'.

But note: The instruction says "escape them correctly for JSON output". So in the JSON string, we must use \n to represent a newline. Also, the entire JSON must be inside a code block labeled as "json".

Implementation:
We'll create two strings: one for shortSummary and one for longSummary, with the required content. Then, we'll put them in a JSON object and output it in a code block.

Let's write the content.

Short Summary (aim for 300-500 words):

Paragraph 1 (Overview):
This week in AI agent startups, there were exciting developments. A new report highlighted top companies, and several big names made news with their latest AI agents. These advancements show how agentic AI is changing the way we work and live.

Paragraph 2 (MarketsandMarkets Report):
MarketsandMarkets, a research company, recognized the top AI agent startups for 2025. They named Leena AI, CUJO AI, Tars, and LawGeex as leaders. Leena AI's platform helps employees by answering questions and solving problems. It can reduce the number of support tickets by up to 70%. This makes work easier and faster for many companies [2].

Paragraph 3 (xAI and Grok-4):
Elon Musk's AI company, xAI, announced that Grok 3.5 is cancelled. Instead, they are launching Grok-4 in July. Grok-4 is expected to be a big improvement. xAI is based in New York and has been working on advanced AI models [4].

Paragraph 4 (Hugging Face and Abacus AI):
Hugging Face, a well-known AI company, shut down its Hugging Chat service. This service let people chat with different AI models. Meanwhile, Abacus AI introduced Deep Agent, a new AI agent that can do many tasks. It can discover information, make decisions, and even improve itself over time. This makes it one of the most advanced agents available [4].

Word count: This is about 200 words. We need to expand to 300-500.

Expand by adding more details:

- In the MarketsandMarkets paragraph, add: The report by MarketsandMarkets helps businesses choose the best AI agent companies. They looked at over 7,000 markets to decide who is leading [2].

- In the xAI paragraph, add: Grok-4 is coming soon and is expected to have better reasoning and understanding. This is important because xAI is one of the top AI startups in the world [3][4].

- In the Hugging Face and Abacus AI paragraph, add: Hugging Chat was a popular place to compare different AI models. Its shutdown surprised many people. On the other hand, Deep Agent from Abacus AI is getting a lot of attention for being so powerful. Experts say it can do almost anything a human can do but much faster [4].

Now, let's write the long summary (800-1200 words). We'll break it into 5-6 paragraphs.

Paragraph 1: Introduction
The world of AI agents saw important news this week. From new reports on top companies to updates from big players, agentic AI is moving fast. These technologies are helping businesses by automating tasks and making decisions.

Paragraph 2: MarketsandMarkets Report (detailed)
MarketsandMarkets released a report on July 1 that names the top AI agent startups and small companies. They recognized Leena AI, CUJO AI, Tars, and LawGeex. Leena AI is a standout because of its conversational AI platform. It helps employees in human resources, IT, and finance by letting them solve problems on their own. The company says it can reduce support tickets by up to 70%. This is a big deal for companies that want to save time and money. Leena AI has even been named a key vendor by Gartner, a famous research company. This report helps businesses decide which AI agents to use [2].

Paragraph 3: xAI and Grok-4
xAI, the AI company started by Elon Musk, made headlines. They cancelled Grok 3.5 and are now planning to release Grok-4 in July. Grok-4 is expected to be a major upgrade. xAI is based in New York and has been working on advanced language models. They built a supercomputer in Memphis to power their AI. Grok-4 is likely to have better reasoning and understanding of the world. This news is exciting because xAI is one of the best-funded AI startups. They are in talks to raise $4.3 billion, which would make them even stronger [3][4].

Paragraph 4: Hugging Face shuts down Hugging Chat
Hugging Face, a company known for open-source AI, shut down its Hugging Chat service. Hugging Chat allowed users to talk to different AI models and compare them. The shutdown was a surprise to many. Hugging Face hasn't said exactly why they shut it down. This change might affect how people test and compare AI models in the future. It also shows that the AI industry is changing quickly, with companies shifting their focus [4].

Paragraph 5: Deep Agent from Abacus AI
Abacus AI, a respected startup, launched Deep Agent. This new AI agent is getting a lot of attention because it can do so much. It can discover information, make decisions, run code, and even get better over time. This makes it one of the most advanced agents available. Experts say it's "magical" and "ahead of others." Deep Agent could change how businesses use AI by handling complex tasks without human help. Abacus AI is known for innovation, and this product is a big step forward [4].

Paragraph 6: Background on AI Startups (from earlier reports)
While not from this week, it's worth noting that the AI startup scene is booming. Companies like Anthropic, Decagon, Cohere, and Writer are leading in generative AI and agentic AI. They are getting billions of dollars in funding. Research firm Gartner expects AI spending to reach $644 billion this year. This growth is driven by the need for better business tools and automation. These top startups are making AI agents smarter and more helpful [1][3].

We must ensure the long summary is 800-1200 words. We'll expand each paragraph with more details and examples.

Now, we write the JSON. We must escape newlines as \n in the JSON strings.

Example: 
"shortSummary": "This is the first paragraph.\n\nThis is the second paragraph."

We'll do the same for longSummary.

Finally, output only the JSON inside a code block labeled "json".
