There’s evidence that combining models can achieve frontier-level performance (e.g. OpenRouter Fusion). I’m wondering if that’s the more realistic option: combine Opus with a local model to save on token costs.
It seems pretty intuitive that pouring more resources into a problem (more GPU, bigger GPUs with more VRAM, bigger datasets, better curated datasets, more efficient ways to train, more efficient way to run inference, etc) then running the result for a longer time, with more layers of verification (running in VMs, model fusion comparing multiple models, having harnesses with testing) will at least lead to marginally better results.
Is it worth it and at what pace will it keep on improving are different questions but I have little doubt that if the industry keep on pouring resources, sure more "works".
