📣 Claude Sonnet 4.5, Anthropic’s most advanced model for coding and real-world agents, is now rolling out in GitHub Copilot to Copilot Pro, Pro+, Business, and Enterprise ⬇️

Everyone flexes “Claude Sonnet 4.5 in Copilot 🚀” But real devs know: 🔹 Tools ≠ Agents 🔹 Autocomplete ≠ Intelligence 🔹 Hype ≠ Breakthrough Until models can own context, reason beyond tokens, and run locally without corporate wires → it’s just a shinier autocomplete. Wake me up when we see real autonomy.

Rolling Sonnet 4.5 into Copilot is big curious to see diff quality, test coverage hints, and fewer hallucinations

Cringe

Is it available now ?

github moving fast on this integration. copilot w/ sonnet 4.5 might actually shift the whole cursor vs copilot debate now that the model gap is closing

Quick turnaround!

Big win for devs & GitHub Copilot users. Future of AI coding looks 🔥

give my copilot back 🥲

And we have also in @warpdotdev I'm wondering about the comparison between version 4 and 4.5

guess this means the end of the road for OpenAI's codex

Sonnet 4.5 demonstrates AI's shift from reactive to anticipatory. Rather than merely following instructions, it suggests next steps based on workflow patterns, transforming interactions with your personal agent.

That was fast

What is the context window?

Excited to see AI advancing in developer tools

Okay trying it now

GitHub running so fast. Ain’t no one like @github 😍😍😍

Awww, am happy rn cus I’ve been counting down for this drop like it’s deployment day. GitHub really came through Sonnet 4.5 in Copilot? Wow Let’s work……🧠🔥

That’s huge!

Awesome

Big step forward for developers. Claude Sonnet 4.5 in GitHub Copilot means faster problem-solving and more reliable real-world coding assistance. Excited to see how this raises the bar for AI-powered dev tools.

Please add crypto payment option for your Copilot subscription Thank you

does it support thinking tho ?

Stronger coding models make agents more capable. At Coral we focus on orchestrating them into reliable workflows in production.

Wow 😯 This is a game changer.

can't wait to try :)

Indeed, more from Anthropic then

Please reset the premium requests 🙏

What’s interesting is the positioning: Claude is orienting toward “doing work” (coding, agentic tasks) rather than just “answering queries.” It’s a shift in narrative from tool to collaborator. We’re entering a new phase in human-AI partnership.

just what I needed, a copilot that's almost as lazy as me

It's only for @code like GPT-5-Codex?

I'm still waiting for access to GPT-5 Codex, but it hasn't appeared on my end. Is it restricted to certain users or plans?

Not yet on mine. 😭
