If you have ever tried to ship a real product, you know the hardest part is not the idea. It is the grind in the middle. The bugs, the integrations, the missing edge cases, the failed deployments.
That middle part is exactly what Deep Agent now takes off your plate.
With its latest upgrade on Abacus AI, Deep Agent can build full web services by itself, from complete back-end logic to live API endpoints, all the way to a finished working service you can plug straight into your stack. It runs on an upgraded setup with Gemini 3 inside ChatLLM, and for the first time, the output looks and feels like work a real team would ship.
This post walks through what changed, how Deep Agent actually works in practice, and what its new demos say about where autonomous engineering is heading in 2025.
Deep Agent’s Massive Upgrade: From Helper To Autonomous Builder
A year or two ago, building a serious SaaS product meant a long, painful journey.
You needed authentication, payments, a database, internal dashboards, user roles, real business logic, and a deployment pipeline that did not collapse under load. For most teams, that meant:
- A long timeline, usually half a year or more
- A high cost, often $300,000 to $400,000 in 2023
- No guarantee the product would ever reach a stable point
- A process that felt like a constant war of attrition
Deep Agent’s latest upgrade flips that story.
Now you describe what you want, and the agent builds:
- The API contract
- The back-end logic
- The external integrations
- The deployment flow
- A production-ready endpoint you can hit from your own stack
You do not get a half-finished prototype. You get something that runs, responds, and can already sit inside a real system.
If you want to see what the team is officially positioning it as, the main overview on the Deep Agent product page at Abacus AI explains the platform from their side of the table: Abacus AI Deep Agent overview.
Gemini 3 and ChatLLM: More Power Under The Hood
This upgrade landed at the same time Gemini 3 went live inside ChatLLM on Abacus AI.
That matters because Deep Agent now rides on a stronger, more capable stack. The demos look a lot more like real infrastructure work than earlier versions, both in terms of code quality and the shape of the systems it creates.
If you want to experiment with the model layer itself, you can try the Gemini 3 integration inside ChatLLM on Abacus AI here: Gemini 3 in ChatLLM.
The practical result is simple. The agent is faster, breaks less often, and can handle more complex workflows without falling apart.
From Half A Year To Half An Hour
Speed is the easiest part of the story to explain and the hardest to really absorb.
People are already using Deep Agent to build real prototypes in 10 minutes. Not toy examples, but working flows with:
- Stripe integrated
- Authentication handled
- A full dashboard generated from scratch
It sounds like a demo script until you watch it do the whole thing in one continuous workflow. You describe what you want, answer a couple of clarifying questions, and then sit back while the system does the work.
One Continuous Pipeline, End To End
Here is what the new Deep Agent actually does when you give it an idea:
- Designs the API contract, including request and response schemas
- Implements the logic, wiring internal functions and external services
- Builds the workflow, so the different steps talk to each other
- Deploys a real endpoint, reachable from your own stack
On top of that, it:
- Versions everything automatically
- Exposes logs and observability tools
- Keeps the system fully debuggable
This is not no-code in the classic sense. It behaves more like a general purpose back-end engineer that happens to be an AI agent and never gets tired or annoyed.

Autonomous APIs In Action: The Demos That Matter
The real proof is not the claims, it is the workflows that now exist because of this upgrade. Deep Agent’s recent demos cover a range of tasks that used to require a full stack of tools and a patient engineer.
Stock Insights: Real-Time Market Intelligence As An API
The stock insights demo shows what it looks like when an agent acts like a dedicated quant engineer.
You describe the kind of market intelligence you want. That might be price movements, watch lists, indicators, alerts, summaries, or whatever fits your strategy.
Deep Agent then:
- Connects to relevant data sources
- Applies the business logic you described
- Ships a real-time API that your tools can call
The output is a production-ready service that can power internal dashboards, analytics tools, trading systems, or any custom client you care about. Instead of juggling spreadsheets and random scripts that break every two weeks, you get a stable endpoint with consistent, current data.
Behind the scenes, it handles:
- Schema definitions
- Data fetching
- Normalization
- Error handling
You only handle the intent.
Memory-Rich Telegram Chatbot: One Brain, Many Frontends
Most chatbot demos are shallow. They forget context as soon as the tab closes.
The memory-rich Telegram chatbot takes a different approach. You start by describing:
- The personality
- The tone
- The capabilities
- The behavior you want over time
Deep Agent then sets up:
- Long-term memory
- Context retention
- Identity tracking
- Adaptive responses over many conversations
The intelligence lives behind callable APIs. Telegram is just one frontend. You can plug the same brain into a website, a mobile app, internal tools, or anything else and get consistent behavior everywhere.
That is what a real conversational system looks like when an agent builds it.

Invoice Extraction: Handling Messy Documents Without Handwritten Parsers
Invoices are a classic “annoying but important” problem.
Different formats, layouts, fonts, table styles, languages, and missing fields make traditional parsers fragile. Usually you end up writing and maintaining a pile of custom code.
With the invoice extraction workflow, you feed Deep Agent example invoices in different formats and layouts. From there, it:
- Figures out the right fields on its own (vendor, dates, totals)
- Pulls line items, taxes, and other key values
- Builds a pipeline that can handle new invoices reliably
Once the pipeline is ready, Deep Agent deploys it as an API endpoint. Your ERP system or finance tool calls the endpoint, and it returns normalized data regardless of how ugly the original invoice was.
Here is a simple way to think about the transformation:
| Input example | Output structure |
|---|---|
| Scanned PDF with table layout | JSON with vendor, date, total, currency |
| Email-style text invoice | Parsed fields plus line item breakdown |
| Complex multi-page invoice with taxes | Structured items, taxes, discounts, totals |
You do not micromanage parser rules. You just define what “clean output” should look like.
Sentiment Intelligence: Turning Free Text Into Clear Signals
The sentiment intelligence demo focuses on another messy input: raw text.
You can feed it:
- Reviews
- Customer feedback
- Comments
- Call transcripts
- Survey responses
Deep Agent turns that into structured data. It extracts:
- Overall sentiment
- Key themes
- Satisfaction levels
- Frustrations
- Product issues
- Feature requests
All of this becomes a unified endpoint your analytics tools can consume. Instead of reading thousands of comments by hand, you query a clean, structured view of what people actually feel and say.

Building Full Applications: When It Stops Feeling Like A Demo
APIs are one thing. Full apps are another. The new Deep Agent handles both.
What feels most surreal is that it not only generates working software, it also debugs it by using a virtual computer like a real tester.
Tutoring Booking Site: From Short Prompt To Live Payments
In the tutoring booking site demo, the agent builds a complete product flow from a short prompt.
It creates:
- A simple landing page
- Integrated Stripe payments
- A pricing structure
- Session durations
- A working booking flow
The agent asks a few clarifying questions, then tells the user where to paste the Stripe publishable and secret keys. It handles the rest of the integration by itself.
The wild part is what happens next. Deep Agent uses a virtual computer to:
- Open a browser
- Inspect the console
- Click buttons
- Fill forms
- Fix what is broken
It behaves like a patient QA engineer who can repeat the same test flow as many times as needed without complaint.
Lead Magnet Site: Tiny Product, Full Flow
The lead magnet demo shows how even a simple funnel can be set up in minutes.
The flow looks like this:
- A user enters their email
- They pay $1 through Stripe
- They reach a download page with an upsell offer built in
Everything works end to end. Payments, access, and upsell are all wired together. You can open the code and tweak any detail manually, or keep talking to Deep Agent and ask it to refine copy, layout, or logic.
For small info products or early audience tests, this kind of speed removes almost every excuse.
Resume Reviewer: A Real MVP From One Short Prompt
The resume reviewer demo shows how Deep Agent handles heavier AI-centric workflows.
Here is what happens:
- A user uploads a resume
- The system sends the text through the user’s own OpenAI API key
- Deep Agent interprets what is written
- It breaks the content down and highlights how strong the resume is overall
- It returns clear, actionable feedback
On top of that, it offers an optional $9 per month upgrade, processed through Stripe, for people who want a deeper breakdown.
All of this, from the analysis pipeline to the subscription flow, comes from a single short prompt.
You basically get an MVP backbone of a product that looks like something a small team would spend weeks building. You, as the creator, stay at the level of idea, feedback, and direction, not wiring and deployment.
If you are curious about the pricing and tiers behind Deep Agent itself, Abacus AI has a FAQ section that lays it out: Deep Agent FAQ and pricing details.
The Bigger Picture: We Are Already In The Agent Era
It is easy to talk about “the future of AI” as something far away. The truth is that 2025 already feels different for teams who ship technical work.
Autonomous agents are moving beyond coding helpers. They build, test, deploy, and maintain full systems with far less human guidance than before.
In the video’s timeline, the shift looks roughly like this:
| Year | Shift |
|---|---|
| 2025 | Autonomous agents for serious technical builds |
| 2026 | Embodied intelligence for physical systems |
| 2027 | Systems that improve themselves over time |
We are not warming up anymore, we are already playing the main event.
Deep Agent happens to be one of the first widely available tools that shows what this looks like in real, practical use, not theory. It turns ideas into services, workflows, and products you can actually ship.
Community, Challenges, And What Comes Next
Abacus AI is not building Deep Agent in a vacuum.
They run weekly challenges with prizes up to $2,500 for the best projects built on the platform. That means the tool is being shaped by actual builders trying to solve real problems, not just internal test cases.
At the same time, Gemini 3 is live inside ChatLLM, and the platform feels like it gains new abilities every month. The direction is clear: more autonomy, more stability, less friction.
If you want to explore the broader assistant experience that includes Deep Agent and multiple model options, it is worth looking at how Abacus positions ChatLLM as a hub: Abacus AI ChatLLM and super assistant.

The gap between idea and working product used to feel like a mountain. Specs, tickets, handoffs, meetings, and late night debugging sessions were the cost of entry.
With Deep Agent’s latest upgrade, that gap feels more like a short, calm walk.
You describe what you want, then an autonomous agent acts like a quiet back-end team that designs APIs, wires services, deploys endpoints, and even tests the product for you. You still bring the judgment, the taste, and the strategy. The AI simply handles the part that used to drain your time and energy.
If you build products, lead teams, or just like turning ideas into real things, this is a good moment to pay close attention. The tools are here already, not in some distant future.
The next question is simple: what will you let an agent build for you, while you focus on the work only you can do?
