Claude Sonnet 4.5 is probably the “best coding model in the world” (at least for now)
September 29, 2025 - The pricing is the same as the previous Sonnet: $3/million input tokens and $15/million output tokens. This remains significantly cheaper than Claude Opus—$15/$75—but still quite a bit more than GPT-5 and GPT-5-Codex, both at $1.25/$10.

r/GithubCopilot on Reddit: Cost comparison cline (sonnet 4) vs copilot (sonnet 4)
May 25, 2025 -

Hello
Probably claude sonnet 4 is one the the best option today for cost/quality agent.
I'm using copilot pro now with 300 premium requests (almost any request that has contact with your files or project will be considered premium), which is actually not that much. I would say that less that i wish. I also tried using the cline agent with the claude sonnet api via cline (in that case you also should pay for cline a little). It seemed to me that using claude sonnet 4 via copilot is a little cheaper. Has anyone made any similar comparisons for themselves?

r/GithubCopilot on Reddit: Claude Sonnet 4.5 (preview) in GitHub Copilot is addicted to “comprehensive summary documents”
October 3, 2025 -

Been trying out the new Claude Sonnet 4.5 coding agent in GitHub Copilot. Honestly? It’s incredibly good fast at coding, nails fixes, feels like cheating sometimes.

But it has this one hilarious quirk: every tiny request, even a one-line bug fix, and it’s like, “Sure, here’s your code... oh, and also a comprehensive summary document in Markdown.” and this happens several times in one session so the .md files keep piling up quick.

So you end up with perfect code and a project report you never asked for. Not a dealbreaker, just funny that "best coding model in the world" also moonlights as your unsolicited technical writer.

I am using this feature HEAVILY to my advantage and it literally transforms Sonnet into the best three senior developers that I've ever had working for me. I promise that if you try this approach, you will never look back: Get Sonnet to create a PHASED "feature planning" document for a single WELL-DEFINED ticket (I've got it to talk to Jira via powershell. If you're using git issues, it has native access to those), to include a section on progress and another on questions for clarification. The resultant file goes into a .gitignored folder and is named in line with the ticket number. I've updated the .github/copilot-instructions.md to understand all this. Next, open N x Visual Studios (for me N is 3, maybe start with 1!) and each on a different worktree. If you're not familiar with worktrees, they let you use one local repo, but with different folders on different branches. Now rotate amongst them. This is HIGHLY efficient. Yes it churns tokens. Yes it's worth it! When each planning document has no more clarifying questions, let it set about each phase with copilot-instructions. I get it to use me to validate completeness of the phase before proceeding to the next. I use regular staging / commits to carefully manage its progress and have no qualms about ditching changes in git, resetting the conversation and just say "we're working on XY-12345. . Update the plans and continue". Because the plan/progress document is being kept up to date, you can interrupt progress, suffer IDE crashes without impact etc. Finally, once the feature is complete, have it: Attach the .md to the ticket Write a test plan Pass the ticket to Q/A Clean up after itself. Side note. Use Windows H to work at the speed of thought, but also to permit you to stop and think without having a ChatGPT-like experience of the AI hating silence and talking to fill the gaps. Suggestion: Create a ticket in your ticketing system with a hyperlink to this comment and ask it to PLAN how you and they can work together better in future. Tl;Dr: Documentation is good, and embracing that will make you a better software engineer.

r/GithubCopilot on Reddit: Is switching from Claude Code to GitHub Copilot (Sonnet 4.5) worth it?
November 17, 2025 -

Currently using Claude Code but considering the switch to GitHub Copilot now that it supports Sonnet 4.5.

Cost comparison:

  • Claude Code: ~$1200/year (already spent $600 in 6 months)

  • GitHub Copilot: $468/year

For those who've made the switch, is it worth it for the GitHub ecosystem integration? Any major feature differences I should know about?
