I used GitHub Copilot for my VS 2026 development and switched between ChatGPT and Claude. That was before I discovered Claude Code and the Codex app. Copilot was OK for my purposes, and the USD 10 per month fee was enough for my usage. However, last month they introduced a new pricing model ( I know the old pricing was not sustainable), and my USD 10 was exhausted within days. Because of that, I switched to Claude Code and Codex and have never looked back. Yes, tokens on Claude Code and Codex are subsidized heavily, but let's just enjoy when good things last. I do feel there is a difference between using Claude via Copilot versus using Claude directly in Claude Code. I'm not sure what Microsoft is doing behind the scenes.

I had a similar experience moving away from Copilot within Zed. Now using the reasonix harness for Deepseek that makes cache hits almost free. And that's with unsubsidized American providers like Digital Ocean or Cloudflare.

  Nice. I paid $6 yesterday for DeepSeek V4 Flash on OpenRouter. That's like $120 dollar for a month, and it's not even a good model.

    For DS4 it's much cheaper and reputable to use OpenCode Go $10/mo subscription, or directly with DeepSeek API.

      Thanks! I'll try that.

      Sometimes $10 is more than I'll do with API tokens. I prefer the top up scheme for peace of mind, but the deal does sound generous. The only concern is sustainability, similar to subsidized copilot pricing having to change.

    That's quite an achievement, I managed to spend only 2$ on 16 different tasks of v4 pro.
    - k__ 3mo ago
      Yeah, v4 flash is dirt cheap, but it's running in circles quite often. Might very well be that a better model is cheaper if it gets things right the first try. Maybe I should route to a better model when v4flash hasn't solved after a specific number of tokens.

        I'm having great success with DS4 Pro as my main model, while using DS4 Flash for subagents.
        k__ 3mo ago
        I tried DS4 Pro yesterday for one particular task that Flash struggled with. That one Pro task cost $1.50 and the whole day of using Flash cost me $5.

  I tried using Zed but with local models it constantly breaks on tool calls. I wanted to like it but the smell of vibing is just too much.
  - arcanemachiner 3mo ago
    You using models released this year? I hear this complaint a lot, and it's often due to using an old model which is not as good at tool calling as newer models.

      Qwen 3.6 and 3.5...

      What I noticed is that when the conversation starts the agent is pretty able to read from and write to files. As the conversation continues (and maybe sub agents are spawned) it forgets how to do this, complains, tries to resort to running shell or python code, sometimes it works. Sometimes it asks me to execute the code. If I refuse and point out it worked before than sometimes it remembers how to write, but mostly not and I need to start a new session. When using Zed with the CoPilot integration I use Claude Opus and never had this issue.
  - arikrahman 3mo ago
    Likewise, and that's with state of the art technology. I wish a true self-contained binary for Reasonix Desktop was released, for now I have to settle for providing a Flake.nix environment. It isn't nearly as fickle as Zed, but I wish they leveraged that power of the Go toolset more.

  What is the average monthly token price for daily reasonix use?
  - arikrahman 3mo ago
    For me it's about $5 of work, where I've done equivalent work for about $200.
- sydneypan 3mo ago
  Yep reasonix is an absolute case study of caching. They literally compiled byte level cache in their design and it is insane. i can one shot many workflows, apps in under 0.05 cents.

My copilot quota finished in maybe 2-3 prompts with claude 4.8 opus. i was expecting it to suck but not this bad. it was good while it lasted though

The harness is super important, what tools are available and the system prompts vary from harness to harness. Anthropic seems to have a modest lead on their harness and models, so it’s a best-of-both-worlds scenario. > I'm not sure what Microsoft is doing behind the scenes It’s probably the exact same model, but the tools and the prompts around it are worse, so you get worse results.
- Vinnl 3mo ago
  So if you use Claude via Copilot in Zed... You use Zed's harness, I think? What does Copilot do, at that point?

    I believe you are using https://github.com/github/copilot-cli https://github.com/github/copilot-cli or potentially this https://github.com/github/copilot-language-server-release#agent-client-protocol-acp-preview https://github.com/github/copilot-language-server-release#ag... via the Agent Client Protocol https://github.com/agentclientprotocol/agent-client-protocol https://github.com/agentclientprotocol/agent-client-protocol which means you are indeed using Copilot's harness ACP is just a standard that bridges harnesses easily into IDEs, Text Editors, or whatever consumes it (I wrote a TUI that consumes them) The registry for all the agents (tool harnesses) is here https://github.com/agentclientprotocol/registry https://github.com/agentclientprotocol/registry if you ever are curious to what Zed or IntelliJ are really hooking into
    - Vinnl 3mo ago
      Ah OK, so the ACP connector ensures tool calls work with Zed, and communicates the available tools and their results to the harness, and then the harness mainly provides a system prompt and the API calls?

GitHub Copilot costs have ballooned in recent week, what once took $100 requires $300. I like using Claude with VS Code through Copilot and I feel it’s given me much better code, that I can control the quality. It’s much more transparent than Claude Code. It’s open source but and the IDE interface gives so many more features to have you context and control over whats generated. The increase in cost isn’t purely due to their price increases but also the Opus models agents use more tokens. So I’ve moved to Claude Code and I’m happily still using Opus 4.6. Fable and 4.7 seem to do much larger units of work, go off on tangents and make assumptions that frequently results in slop.
