building tools I wanted, and open sourcing them…

[Tom Ballard @tcballard]

Most LLM routers decide where to send a prompt by… calling another model.

Wayfinder doesn’t.

It reads the prompts structure - deterministic, offline, microseconds - to keep cheap prompts on your local model and send hard ones to the frontier ones.

Self-hosted, bring your own keys, OpenAI-compatible

@gokulr Product Specs == a series of artifacts, not just one.

@VulcanBench ngl those reports look *chefs kiss*

@sivalabs this is why I build lore as I was suffering with this drift…

@gregisenberg This is why I did this…

@StevenMathern using fable it was pretty easy, and the prompt was fairly basic… you just have to make clear that the current test battery you have is the contract you are implementing against… but I made clear Fable was the orchestrator, and all agents it dispatched should have been Opus :)

[Tom Ballard @tcballard]

I propose a new SWE benchmark: RebuildFromTests

I thought I’d test Fable out on something people always claim the latest frontier model can do.

It’s not merged, but it’s sat there.

When OpenAI drop Sol I’ll run the same exercise, and see what the results are.

Watch this space

@mattpocockuk @albertgao @DevinAI maybe I try wayfinder with wayfinder... a little collab :D

@undefinedKi @garrytan shame nobody mentioned https://t.co/gRG03mdGeX

@chamath the fact anything still runs on COBOL is insanity.

[Tom Ballard @tcballard]

@ericosiu prompt where? Because this looks cool

[Tom Ballard @tcballard]

@marckohlbrugge @openclaw I approve this message. But even so, @steipete should hit Ethan up

You've hit your session limit · resets 10am (Europe/London) ... and im on the Max 20x plan

its 7:30am @DarioAmodei ... what am I supposed to do now?! Touch Grass?!

@andrewmccalip the diligence on this 'side project' is a bit of an inspiration... if only the desktop apps exposed the ability for you to work with them as well, would open up the 'consumer' ecosystem and not just the "hardcore" dev one

@chamath weirdness tax… or just knowing your customer
