    Introducing Code Review, a new feature for Claude Code. When a PR opens, Claude dispatches a team of agents to hunt for bugs. [video]

    If you want AI Code Review, but don't want to pay $25 per review (not a typo), check out Codex Review! It leverages frontier Codex models, finds complex issues, and 100% usage based. Most runs should cost ~$1 or less https://developers.openai.com/ ...

    $25 per PR review The frog is starting to boil
  • @lanreadelowo @lanreadelowo on x
    Claude code writes the code then reviews it for $20 then finds critical issues then Claude code fixes those issues. Only for Claude code to review it again for $20. AGI

    Introducing Code Review for Claude Code. A deep, multi-agent review system that catches bugs that even human reviewers often miss. This is the system we've been running on nearly every PR at Anthropic. Doesn't approve PRs, but helps close the gap so devs can keep up. [video]
  • @rhyssullivan Rhys on x
    A $15-$25 PR review bot that catches an incident which would've cost the company $5m in breached SLAs and reputation is a no brainer

    Code review commoditized.
  • @jarredsumner Jarred Sumner on x
    Been using this in Bun's repo for weeks & giving lots of feedback This, imo, is the best product in the code review category today. It regularly catches extremely subtle bugs and rarely makes mistakes
  • @claudeai Claude on x
    Agents search for bugs in parallel, verify each bug to reduce false positives, and rank bugs by severity. You get one high-signal summary comment plus inline flags.

    Code Review is so so good. One of those things I can't remember how I lived without.
  • @dillon_mulroy Dillon Mulroy on x
    i'm convinced we have the best code review agent at cloudflare and it's not even close in terms of quality signal to noise
  • @claudeai Claude on x
    Code Review optimizes for depth and may be more expensive than other solutions, like our open source GitHub Action. Reviews generally average $15-25, billed on token usage, and they scale based on PR complexity.
  • @lucas_montano Montano on x
    we need to admit defeat we won't be reviewing code before it goes to production humans are already the bottleneck
  • @kayvz Kayvon Beykpour on x
    Sensible for Claude to launch this and we plan on benchmarking to see how it compares. But fwiw $15-25 per review is well over an order of magnitude more expensive than @Macroscope. Not because we want to subsidize model costs, but because architecturally our agent can use
  • @icesolst @icesolst on x
    $15-25 PER PR?? I already thought the $1 per scan of /security-review was not scalable, this must be a weird strategy to anchor the initial price super high
  • @bcherny Boris Cherny on x
    New in Claude Code: Code Review. A team of agents runs a deep review on every PR. We built it for ourselves first. Code output per Anthropic engineer is up 200% this year and reviews were the bottleneck Personally, I've been using it for a few weeks and have found it catches
  • @derrickcchoi Derrick Choi on x
    $25 per code review... is a lot. @OpenAI Codex code review costs 90% less than other solutions on the market, and we're seeing enterprises like Datadog ( https://openai.com/...) move their code review workflows entirely to Codex. Also Codex Security is free for the next month
  • @gilgnyc Gil on x
    Imagine spending $15-25/pr on code review and you still have daily downtime and buggy releases. I'd be more confident in this feature if their production quality was higher. [image]

    “Reviews are billed on token usage and generally average $15-25”  —  sounds high, but it means they take themselves to have solved the problem.  the challenge with LLMs is to get them good enough where throwing more tokens at a problem gets you more. then you throw as many tokens…

    > Reviews are billed on token usage and generally average $15-25  —  Seems like an accurate cost-per-token compared to heavily subsidized alternatives  —  Companies that haven't priced in current discounts are going to get rekt when the “find out” phase begins  —  claude.com/blog…

    People's comments on the $15-25 per PR price tag remind me of Michael Bloomberg's answer to people balking at the $2,700 / mo cost of the Bloomberg Terminal: “if you can't make $2,700/mo with our product, you got bigger problems to deal with”
  • @weswinder Wes Winder on x
    i really don't understand why you would pay $25 for claude to review a SINGLE pr when opus 4.6 isn't even the best model for deep code review gpt 5.4 is the only model i trust for reviews rn

    We've been running this on most PRs at Anthropic. Results after months of testing: PRs w/ substantive review comments went from 16% → 54% <1% of review findings are marked incorrect by engineers On large PRs (1,000+ lines), 84% surface findings, avg 7.5 issues each
  • @pxue Paul Xue on x
    I get the trade off is hiring a dev for $100+/hr so having Claude review a PR for $15-25 feels like a no brainer. But the problem is Claude will never tell you your PR is stupid in the first place. A good dev will, and that's priceless.
  • @bcherny Boris Cherny on x
    @Rahll 👋 Roughly, the more tokens you throw at a coding problem, the better the result is. We call this test time compute. One way to make the result even better is to use separate context windows. This is what makes subagents work, and also why one agent can cause bugs and anoth…

    this is fucking ridiculous lol - anthropic just killed a $50B industry with a single feature (again): - companies pay $50K a year to scan their code for vulnerabilities. - anthropics Code Review does it for you in minutes for a fraction of the cost. - deploys multiple agents

    1. Subsidize code generation 90% so everyone forgets how to read/write code manually. 2. Now charge 10x - to ensure the generated code - that you largely can't understand - actually works. Donut and Dietician shop working out of same office.
