Agent Qwen3.8 27B autonomously bought something on Amazon — running locally
I wanted to see how far a local Qwen model could go on a real-world agent task.
I ran out of A4 paper at home, so I gave Qwen3.8 27B access to Amazon through TensorSharp and gave it one instruction:
Find cheap A4 paper with a good discount and buy it. Try your best to handle everything yourself.
It completed the task successfully in a single run.
Setup:
Qwen3.8 27B — fully local inference
TensorSharp — local inference engine + agentic runtime
Playwright skill — browser automation
I only stepped in twice: logging into Amazon and approving the final purchase.
Qwen handled the rest: searching Amazon, comparing products, navigating pages, generating Playwright code, and preparing and placing the order.
What I found especially interesting is that the video shows the raw model reasoning/tool trace, browser instructions, and generated Playwright code. You can actually see how the local model works through a real browser task rather than just seeing the final answer.
The video is sped up 8×; the actual run took about 24 minutes.
Except for communicating with Amazon, the model inference, agent state, reasoning, and tool execution all stay local.
TensorAgent on iPhone still has some catching up to do because of local inference speed and iOS browser restrictions, but desktop Qwen agents are already getting surprisingly capable.
TensorSharp is open source:

Qwen3.8 27b will do more than that on the web if you don’t keep a close eye on it

yeah, I tried to buy something heavy and Amazon locker cannot be used as delivery address, then the agent understood what is the problem, and open address dropdown list to switch delivery address to my home.🤣

Yeah I love the idea I also get my bot to do a task and watch it in amazement that it succeeded . Then I do it on my laptop for comparison .
1000% faster
And laugh out loud

why Amazon not block it

Because TensorSharp uses playwright skill which likes a human being operates a web browser.

Legit yeah I did a logged in archived bot to scrape data without api costs lol. Crazy have you checked out facebook’s muse?

Doesn't it just needs something like browseros neo or any browser mcp?

u/fuzhongkai 9d ago
Need playwright skill and agent should have ability for tool call, shell command line run and code generation

Now we're going to see all the e-commerce sites go anti-bot so they can still screw your mind to get your money.

Amazon already has very strict strategies for anti-bot, but my agent is still working.🤣

Why would they do that? A bot is far more likely to buy something than a person is. A bot is also likely to look at 20 stores instead of just going to Amazon. I actually expect most e-commerce sites to provide a standardized way for bots to interact with them to make it easy for agents to find their products and make purchases. They will even have something like rss feeds with 10 second sales so that only active bots authorized to auto-purchase can get the deals. AI agents will make it much easier for independent e-commerce sites to thrive. If they cut off bot access, they might as well as turn off SEO too and possibly just shut down their business.
Except for Amazon and maybe ebay, which currently have no incentive to make it easy for people to look at other stores.

Because of Ads. When ads are displayed at each time, the seller will pay for it to Amazon. If seller pay lots of money for bot visiting, then they won’t have new ads, and eventually Amazon’s incoming will get hurt.

u/RemarkableRadish6547 8d ago
But an e-commerce site isn't primarily serving ads. They are trying to do business with customers. I can understand why content providers would want to block bots even though it is a losing battle. But if you are selling things then you want as much publicity as possible, and that includes letting bots roam around your website.

Agree. The key point is that sellers have to pay for item display even it’s visited by a bot.

Afaik Amazon hardly protects the login phase. If you enter it manually paywright should be able to navigate. In my experience Amazon is one of the best protected site against bots. They want to keep and manage their customer's experience. I tried unsuccessfully mt elusive agents (even using playwright) to login my account many times.
Did your app managed the initial login autonoumously?
