@LyricaLemonade Tbh I really think he can catch this wave

[Franky. @FrankYouChill]

@niftyalpha It’s not free on OpenRouter. I guess there’s a misunderstanding on what’s Free: we have 1-week free promotion on 4 agent partners

[Franky. @FrankYouChill]

So excited to bring Step 5 Preview to y’all!

If you’ve got an idea or what to build something for yourself, let’s make it happen: whether you’re a coder, a builder, or a user.

Tag me when you share your best builds with StepFun models. I wanna see what you doing.

All best

[StepFun @StepFun_ai]

Step 5 Preview now exists where you build.

Now live on @OpenRouter. A week of free access is rolling out today across @opencode, @cline , @NousResearch, @kilocode, and more.

Flagship-tier intelligence for agentic and professional work, at substantially lower task cost.

Keep your workflow. Switch your model.

Guys that’s a honeybee. I confirmed that with my glasses on. @vikktorrrre man you nailed this

[Veee @vikktorrrre]

Step 5 Preview from @StepFun_ai built this interactive 3D honeybee in just a few iterations.

I refined the fur, eyes, wings, lighting, and animations until it felt much more realistic.
