Could you build this?
Yes This is an exploratory research blog post or lightweight model fine-tune demonstrating targeted data poisoning or fine-tuning using existing PyTorch/Hugging Face scripts.
Discussion
8 comments analyzed.
Competitors mentioned: Fable 5, Codex, autoregressive models, SmolLM-135M
Concerns raised: Cost of running agents can get expensive quickly, Unclear how much human vs LLM input went into website/writing, Text reads AI-generated, off-putting to readers, Experiments run at too large scale given resources, ML experiments unreproducible and messy
Feature requests: Write-ups of what went wrong and failures, Run experiments at smaller scale to discover bugs more easily, Test bidirectionality beyond 2000 steps

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
