Bullet: A Coding Agent That Cuts Latency, Not Corners
Launch HN: Bullet (YC S26) – A Faster Coding Agent
Bullet (YC S26) is a macOS coding agent designed to eliminate the frustrating wait times of AI-assisted development. By routing simple tasks to fast models, using targeted repository search instead of full embeddings, and executing independent tool calls in parallel, it accelerates the agent loop without sacrificing accuracy. The team built it out of their own frustration with existing tools like Claude Code, and it's now in private beta with free access.
Don't let your code hold you hostage.

This is a promising direction! Unfortunately, I think the benchmark result here is essentially meaningless.
I recently discovered this same lesson the hard way. I was trying to get a multi-agent system I was building to improve upon GPQA Diamond scores (system here: http://pellmell.ai). No matter how hard I tried, I could not get any lift. When Fable 5 dropped, it also did not improve upon Opus, and I realized my mistake. The benchmark was saturated!
Now, looking at the result here, I see a similar pattern. Fable is not better than Opus, and the score is ~95%. Notably, this post omits which subagent is being used. Why? An intellectually honest way to tell if this thing really works would be to run that agent and report its score and cost as well.
Going back to my GPQA Diamond lesson, you can see here how a saturated leaderboard behaves https://artificialanalysis.ai/evaluations/gpqa-diamond. Fable gets 92.6% for $0.22 per task while several models score higher for $0.01. I could easily publish a router that “enhances Fable on GPQA Diamond” showing improved score for lower cost, just by implementing a router that picks the model at random!

Congrats on the launch.
I can't find which model providers are supported?
Are you calling the claude-code CLI directly and make bullet usable with anthropic subscriptions like orca or herdr?
I guess however this is a harness and it needs to connect to the API?

> P.S: we hid a code on the website, see if you can unlock the secret page at the footer, all built with Bullet
Is it even hidden when your AI ends up tagging it with `aria-label="Hidden secret code"`? Lol. Fun mini game.

Focusing on execution speed for coding agents is the right bottleneck to tackle. Exciting launch.
