Github Copilot and Claude code are not exactly competitors. Github Copilot is autocomplete, highly useful if you use VS Code, but if you are using e.g. Jetbrains then you have other options. Copilot comes with a bunch of other stuff that I rarely use. Claude code is project-wide editing, from the CLI. They complement each other well. As far as I'm concerned the utility of the AI-focused editors has been diminished by…

This isn't correct. GitHub Copilot now totally competes with Claude Code. You can have it create an entire app for you in "Agent" mode if you're feeling brave. In fact, seeing as Copilot is built directly into Visual Studio when you download it, I guess they have a one-up. Copilot isn't locked to a specific LLM, though. You can select the model from a panel, but I don't think you can plug in your own right now, and t…

Is Copilot's Agent Mode any good, though?

o3 and o3-pro are just so good. Sonnet goes off the deep end too often and Opus, in my experience, is not as strong at reasoning compared to OpenAI, despite the higher costs. Rarely do we see a worse, more expensive product win - but competition is good and I’m rooting for Anthropic nonetheless!

OpenAI also has Flex processing[1] for o3. I've spent most of my time with Gemini 2.5, but lately been trying out a ton of o3 as it seems to work quite well and I get really cheap tokens (~95% of my agentic tokens are cached which is 75% discount and flex mode adds 50% for $0.25 / million input tokens) [1] https://platform.openai.com/docs/guides/flex-processing?api-...

Which agents support flex mode?

This is so people don't immediately migrate for GPT5

I've made my own fork of Codex that always uses flex, or you can route agents through litellm and make it add the service_tier parameter. I haven't really seen native support for it anywhere.

This seems like a case of reversion to the mean. When one model is performing below average, changing anything (like switching to another model) is likely to improve it by random chance...

Anthropic say Opus is better, benchmarks & evals say Opus is better, Opus has more parameters and parameters determine how much a NN can learn. Maybe Opus just is better

Even if it's better on average, doesn't mean it's better for every possible query

All three major labs released something within hours of each other. This anime arc is insane.

It's definitely a coincidence

But is it just a coincidence

Is there a way to sign up for Claude code that doesn't involve verifying a phone number with Anthropic? They don't even accept Google Voice numbers. Maybe I'm out of touch, but I'm not handing out my phone number to sign up for random SaaS tools.

It's maybe the leading subscription based tool in our field, not a random SaaS tool.

They have zero need for a phone number.

This has been the worse Claude day ever. Just fell apart. Not sure if the release is why, but cursing in documents and can not fix a bug after hours of back and forth.

You're prompting it wrong !

In Zed I switch the AI panel to ask mode and chat with the agent about different approaches and have it draft patches. Then when I think there's a design worth trying, switch to Write mode and have it implement that change + run the tests and diagnostics to verify the code at least compiles, tests pass and follows our style guides. Finally a line by line review + review of the test coverage (in terms of interface sur…

After watching a few videos trying to understand how people were using LLMs and getting useful results I found that even making a simpler version of the fancy planning mode in the LLM IDEs via the instructions.md produced hugely better productivity gains. I started adding an instruction file along the lines of "Always tell me your plan to solve the issue first with short example code, never edit files without explici…

Could you share some of the videos that you watched ? Can you make a video yourself ? That will help a lot of us.
