I don't think it takes care of tone transformation (eg 他是 ni3shi4 -> ni2shi4). Or if it does, my tones are just off. But it's a really cool idea!

Using small threads (see https://ampcode.com/@sqs for some of my public threads).

If you use very long threads and treat it as a long-and-winding conversation, you will get worse results and pay a lot more.

What's super interesting is that Opus is cheaper all-in than Sonnet for many usage patterns.

Here are some early rough numbers from our own internal usage on the Amp team (avg cost $ per thread):

- Sonnet 4.5: $1.83

- Opus 4.5: $1.30 (earlier checkpoint last week was $1.55)

- Gemini 3 Pro: $1.21

Cost per token is not the right way to look at this. A bit more intelligence means mistakes (and wasted tokens) avoided.

Sorry we missed that email! I don’t know what went wrong there, but I just replied and will figure it out. This is definitely not the norm (and Build Crew is a small fraction of our users).

Yeah, I said about coding agents, “it’s obviously the future, but it’s not there yet”. That talk was from the AI Engineer conference in June 2024 (16 months ago). Coding agents have come a long way since then!

It's a big organization of teen coders who build really cool things together. Instead of coding alone, they get to hack on software and hardware projects in person and online with other smart teens all around the world.

You can see full financial and donor information at https://hackclub.com/philanthropy/ as well. Check it out. It's an organization that lots of HN folks would support (and many do). (I am on the board of Hack Club.)

Buildkite is awesome, by far the best CI product and with an amazing team.

New comment by sqs in "AGENTS.md – Open format for guiding coding agents"

Thank you for pointing that out. Just pushed a fix, will be live in ~5-10min.

That draft RFC you mention is superseded by https://agents.md. Now that Amp uses AGENTS.md (https://x.com/sqs/status/1957945824404729997), I made all the former agent file stuff on https://ampcode.com just redirect to https://agents.md.

Just the filename is standardized. The contents aren't, which is exactly right. From the site:

> Are there required fields?

> No. AGENTS.md is just standard Markdown. Use any headings you like; the agent simply parses the text you provide.

New comment by sqs in "Ask HN: Why do Cursor, Windsurf and Claude Code dominate the conversation?"

sqs — Mon, 21 Jul 2025 18:37:29 +0000

Amp has only been out for a couple of months, and it's growing fast. Cursor and Claude Code have been around for longer, but obviously that's not always a good thing since everything is constantly changing. Check on X, like at https://x.com/sawyerhood/status/1945865702159925734 or https://x.com/search?q=%40AmpCode&src=typed_query&f=top.

This is really cool. I used Vibe Kanban with Amp to update some of our docs and UI components, and it was great.

New comment by sqs in "Claude Code: Best practices for agentic coding"

sqs — Sat, 19 Apr 2025 17:13:26 +0000

Is it a very large codebase? Anything else distinctive about it? Are you often asking high-level/conceptual questions? Those are the questions that would help me understand why you might be seeing better results with RAG.

New comment by sqs in "Claude Code Best Practices"

sqs — Sat, 19 Apr 2025 16:46:53 +0000

Tool-calling agents with search tools do very well at information retrieval tasks in codebases. They are slower and more expensive than good RAG (if you amortize the RAG index over many operations), but they're incredibly versatile and excel in many cases where RAG would fall down. Why do you think you need semantic indexing?

It's fundamentally hard. If you have an easy solution, you can go make a easy few billion dollars.
