We benchmarked Fable 5 on 105 code reviews.
It nearly matched on coverage and then trailed on precision while filing 253 comments.
Great at building, noisy at reviewing.
Full breakdown 👇
Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.

if y'all don't wanna pay $80 for local ai autocomplete, we made a completely free, open-source version.
system-wide ghost text, tab-to-accept, inline :emoji: autocomplete, fully on-device.

Been working with @SamAsante on a new company.
Today we’re releasing our first product.
It’s called Typeahead and we’re live on Product Hunt.
You type and inline suggestions appear right in the text field. Tab to accept the full suggestion or right arrow for one word at a time. It learns how you actually write.
Everything runs locally on your Mac, works offline, and you pay once. $79 and you own it forever.
If you write a lot on a Mac, check it out and let us know what you think.
Live on Product Hunt right now → producthunt.com/products/typ…

Do you want to review a 1-million-line PR?
@jarredsumner did not make it easy for either you or GitHub.
Well, Atlas did!
You can check how the agent went on to write the code on the left, and understand the line-block changes on the right. Comments in a separate tab.

We’ve been testing GPT-5.5 in early access and are excited by its performance in code review.
In our evaluation, it delivered a more direct review flow, stronger signal, and better performance on the issues that matter most.
Headline result: 79.2% Expected Issue Found vs 58.3% baseline.

for a long time i never saw agents as more than a first year intern (doing dumb stuff, taking the wrong instruction, forgetting what you'd just told them last week)
now - @coderabbitai agents can work with me in slack AND have memory?!
@harjotsgill how do i get access?

Your engineering team is about to snap. And your AI coding agent is making it worse.
Introducing CodeRabbit Agent for Slack 🎉
A second brain for engineering teams. Because your tribal knowledge lives in Slack threads nobody can find.
At CodeRabbit, we review millions of PRs every week and know how ace engineering teams operate on the planet.
The same three things slow every team we see:
- Context and decisions that live elsewhere.
- Lack of a team-level durable knowledge base

Built for Agentic SDLC workflows, CodeRabbit Agent for Slack solves all three problems in one shot while enabling teams to collaborate in real-time with the Agent.
CodeRabbit Agent is Slack-native and builds your team’s operating context from every thread, every decision, every conversation your team has ever had.

This is bigger than you think.
CodeRabbit Agent for Slack is not just another slack agent. It is going to be the ONLY slack agent you need.
It knows everything about your company, brand guidelines, sales deals, repositories and coding practices, and employee knowledge.
This agent is an all-in-one of all agents, while being enterprise ready and secure.
Everything is sandboxed, so you don't have to worry about it accessing more than you intended while losing no functionality.
Try it out!
