If a Treasurer of a Fortune 1000 company kept all of their cash in one bank they’d be fired for incompetence. Similarly, if the leadership of a Fortune 1000 company bets the farm on only one frontier lab and their models you’re taking a lot of risk. This risk compounds as the labs’ intentions and public actions are bewildering and show them to be increasingly unpredictable. This is why every major enterprise needs a model agnostic “control plane”. Get the work done, increase the productivity, make more money, save costs, increase efficiency but do it with governance, auditability and control. Capabilities across all models are converging. Open source prices are, in some cases, 1/100th of the frontier labs. But governance, control, compliance and collaboration capabilities don’t exist unless you first focus on the right “control plane”. If you do not find such a “control plane”, you’re increasingly taking risk as the frontier labs become increasingly unpredictable. This is why 8090’s Software Factory is used this way in every major part of the economy including governments.

Fable 5 is state-of-the-art on nearly all tested benchmarks, with exceptional performance in software engineering, knowledge work, scientific research, and vision. The longer and more complex the task, the larger Fable 5’s lead over our other models.

Claude Fable is here: the first model in their new Mythos series. It's the new top score on @Zapier's AutomationBench at 17.4%, just two weeks after Opus 4.8 set the record at 15.5%. Our AutomationBench measures what enterprises actually care about: can a model do the work? Find the right CRM record, send the right follow-up, update the right system without breaking anything? We tested 600 tasks across 6 domains. Here’s what we saw: Fable knows when to work smarter instead of harder. That means fewer timeouts and fewer wasted tokens in production. EXAMPLE: One task asked the model to reconcile employee benefits across countries. The HR system's benefit-plans endpoint returned a 404. Fable hit it once, immediately pivoted to the team's spreadsheet and inbox, found the plan data there, and finished the task. Meanwhile, Opus moved on and missed a key detail. That's the Fable pattern. It follows complex instructions precisely (especially the "leave these ones alone" kind), and when it hits a dead end, it goes looking somewhere else instead of spinning its wheels and wasting tokens. PRICING: You may have seen that Fable is 2x the price of Opus. But that's the model rate, not the task cost. In Zapier, Fable came in at $3.67 per task at max effort, only 17% more than Opus 4.8 max at $3.14. tl;dr: Who should immediately upgrade their workflows from @claudeai's Opus to Fable? - Operations & HR - Long Horizon Tasks needing reliability and autonomy - Any workflows where precision accuracy matter more than cost

Here’s your monthly reminder that you shouldn’t be prompting coding agents anymore. You should be designing loops that prompt your agents.
