@paulg For solo builders pre-revenue, $5k is the whole runway.

Ship on the weird domain, buy the .com once people are paying.

[Krushaal @krushalkalkani]

@poteto 1.3T is wild, but tokens are the input.
I'd love to see that chart next to what shipped.

[Krushaal @krushalkalkani]

X is merging X, Grok, Cursor, and Grok Bot into one subscription.

Today Grok Bot alone has 8 different paid routes. This cleans that up.

Real question is price. Premium+ ($40) + Cursor Pro ($20) = $60 now.

Under $60, it's an easy switch for devs on X.

Anthropic shipped Sonnet 5.5 one day before OpenAI DevDay.

Same $2/$10 price.
Beats Opus 5.5 on Terminal-Bench (70.6% vs 66.4%).
30%+ faster.

The bar is set before Sam walks on stage.

Prediction: OpenAI answers tomorrow with a price cut or a cheaper coding model.

[Krushaal @krushalkalkani]

@claudeai Sonnet 5.5 beating Opus 5.5 on Terminal-Bench (70.6 vs 66.4) at the same $2/$10 price is the real headline.

For most agentic coding, the default model just changed.

[Krushaal @krushalkalkani]

Sonnet 5.5 just beat Opus 5.5 at agentic coding.

Terminal-Bench 4.0:

Sonnet 5.5: 70.6%
Opus 5.5: 66.4%
Sonnet 5: 10.3%

That's a 7x jump in one version.

On almost everything else it's close to Opus.

My take: Sonnet becomes the default for most coding work. Opus is for the hardest 10%.

[Claude @claudeai]

Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family.

It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

𝕏 is building its own full-scale meeting platform with 𝕏 Calls...basically its own version of Google Meet and Zoom

You can start instant calls, create meetings for later with a link or code, or schedule them with titles, descriptions, invitees and calendar integration

The experience goes beyond simple video calls with group meetings, custom backgrounds, interactive whiteboards, live chat, reactions and more

𝕏 Calls also includes flexible access controls, letting hosts choose who can join.....everyone, verified organization members, or only approved participants

The biggest upgrade is that 𝕏 Calls runs on a new in-house backend instead of the older Periscope-based infrastructure

It’s currently being tested and could roll out publicly soon

300+ builders packed The DOCK for the Grok Bot Miami Kickoff, night one of the @SpaceXAI Miami Community.

Same people. Bigger mission.

Thank you @ethanolivertroy (SpaceXAI), @palmalabs_ai and @thelabmiami

Challenge winners announced later today.

Miami has the builders.

[Krushaal @krushalkalkani]

@Voxyz_ai Cool stack.

I'd still start with one agent and a shot list before I hire four.

[Krushaal @krushalkalkani]

@merill Cool prompt.

I'd still want a human on auth. Agents miss the "why we skip this check" comments.

[Krushaal @krushalkalkani]

@_simonsmith You should have to wait for Claude and Google too! They are cooking something back there.

[Krushaal @krushalkalkani]

@viticci Claude Code next to the notes is the unlock.

Less paste. Less "which folder was that again.”

[Krushaal @krushalkalkani]

@santtiagom_ I'd flip it sometimes.

Cheap model drafts. Opus only weighs in on the risky bits.

[Krushaal @krushalkalkani]

Grok Bot can link my bank, cards, and investments now.

Spending questions go to the Bot that already has my other tools.

That’s a different kind of teammate.

[Grok Bot @bot]

Grok Bot now connects to your finances.

Link your bank, card, and investment accounts with the new Finance integration, then ask Bot to help manage your spending, investments, and more.

[Krushaal @krushalkalkani]

@slash1sol Claude can grind overnight fine.

The hard part was always the yes/no gates. Pulling those out of the model is the real unlock.

[Krushaal @krushalkalkani]

@spolen23 Will see!

[Krushaal @krushalkalkani]

PREDICTION: if OpenAI's "O" ships at DevDay, the demo will look like Grok Bot.

Always on.
Works while you're away.
Own workspace.

The real test is week two.
I found that out running Grok Bot every day.

[Krushaal @krushalkalkani]

What the connector cannot do yet:

Deposit from my bank
Withdraw to my bank
ATM
Disputes and account settings

Those stay in the X Money app.

The bot does the askable money. Not the whole bank.

[Krushaal @krushalkalkani]

@bot can now move and spend my X Money.

Connect the MCP once.
Ask in chat.
Approve on the tap.

Same account as the app.

[Krushaal @krushalkalkani]

Safety is the product.

Every send, request, move, and card needs approval.
One action per tap. No reuse.

Virtual cards: one merchant, 12 hours, then dead.
Agent Day cap: 12 cards, 12 purchases, $250.

I still hold the keys.
