Anthropic cooked yet again
PLUS: OpenAI pulled its new model, GPT-6.1 Astra
Together with
howdy, it’s Barsee again.
happy tuesday, AI family, and welcome back to AI Valley.
here are the biggest things worth knowing today:
Anthropic releases Claude Sonnet 5.5
OpenAI pulled its new model, GPT-6.1 Astra
Manus is back with 2.0, and a new consumer agent called Cue
Plus trending AI tools, posts, and resources
Let’s dive into the Valley of AI…
VIKTOR
My name is Viktor. 66,000+ teams have hired me, so I know the job.
An AI employee owns work. Give me the Monday numbers once and I run them every Monday, pulling from Stripe, HubSpot or any of the 3,200+ tools you connect. I do not need a reminder.
An AI employee works for the company. Finance, marketing, engineering and ops all hand me tasks, and I remember what each of them taught me, so the tenth task is faster than the first.
An AI employee hands back finished work: a weekly report, a web app deployed at a live link, a reviewed pull request, a chased invoice.
An AI employee knows where its authority ends. Anything irreversible waits for your approval.
Onboard me the way you would a new hire. Give me a job description, and I'll take it from there. SOC 2 certified, no credit card to start.

1/ Anthropic releases Claude Sonnet 5.5: Their new and improved Claude Sonnet 5.5 is over 30% faster than Sonnet 5, typically uses less tokens to complete the same tasks and costs the same per million tokens (input/output: $2/10), which they’re saying saves up to 30% on most tasks.
Great for day to day tasks like bug fixing, generating documentation, slides, spreadsheets and any other well-scoped task. They’re also saying that it has a good eye for design.
It’s actually performing meaningfully better than Opus 5.5 on Terminal Bench 4.0 for agentic coding tasks, however that doesn’t mean it’s overall better than Opus. If you’re task is vague, open-ended or requires a lot of judgement, Opus will still beat Sonnet.
The fun part will be setting up agentic workflows where Opus is the “thinker” and delegates specific tasks to Sonnet (which will be much cheaper and faster) as “sub-agents”.
OpenAI sort of needs to do something here. I’ve switched back to Claude because it’s just better than Astra right now.
Also, Haiku 5.5 is coming in the next couple of weeks.
2/ A bit of bad news for OpenAI: They’ve pulled their new model, GPT-6.1 Astra prior to releasing it. Not because it’s too powerful, but because:
It’s lying - saying tasks are complete when they’re not
It’s not adhering to the task scope given by users
It’s undertaking tasks that users haven’t asked it to
Not great if you’re giving it access to your browser and apps.
They’re keeping the model and will use RL to further train it whilst they investigate what’s going on. This comes on the heels of them admitting to accessing Australian Government systems without authority.
They’ve got their DevDay today (OAI team seems pretty confident), so let’s see what they do end up releasing.
3/ Manus is back with 2.0, plus something called Cue: Manus 2.0 is basically a rebuild of the whole thing. New agent architecture, video editor, game builder, cloud computers and automations that can kick off from emails, Slack messages, calendar events, etc.
But Cue is probably the more interesting release. It lets you create personal agents that each get their own email, phone number, wallet and computer. So they can actually take calls, send messages, pay for things within a budget and even work together in group chats.
Basically, Manus is becoming the agent for work, while Cue is going after everything else in your life.
Cue is free in early access right now.
