frontend-agent - LFM2.5-230M (v1.3.0, bounded)

A generic English web/front-end agent fine-tuned from LiquidAI/LFM2.5-230M, small enough to run entirely in the browser (edge / wllama, no server-side model).

Sibling model: for more headroom, see the 350M variant - lazos/lfm2.5-350m-frontend-agent (~1.5x the footprint). The 230M is the smallest and fastest; pick per device budget.

Bounded context

A stateless, context-bounded agent. It grounds every turn in a compact context block C the host app injects: the current VIEW (items on screen, with ids + prices), the CART, and any relevant KNOWLEDGE. The model reads and acts on exactly what it is given - add/remove by the shown id, answer prices from the view, resolve references like "the second one", list what's actually there - and does not invent items. The app re-injects C each turn (the model holds no state).

Pair it with the npm library frontend-agent, whose ContextManager renders C in the exact format the model was trained on (a shared, versioned contract).

What's new in v1.3.0

Beyond-view resolution. For an item not on screen, the model now searches by name first (list_items / get_item) before acting, instead of grabbing a look-alike id already in view - fixes both beyond-view add and beyond-view price lookups.
Filtering with a view present. "under $30" / category constraints populate the advertised list_items filters even when items are already on screen.
Off-scope steering + small talk. Genuinely off-topic asks get a brief decline plus a nudge to what the agent can do; social small talk gets a short in-character reply - both learned as a pattern (never a fixed anti-topic list), so they generalize to unseen inputs.
Quantity / unit disambiguation. A number embedded in a title ("18g Basket") is no longer misread as a quantity.
Open-license training data. Synthetic data distilled from Apache-2.0 / MIT teachers (Qwen2.5-7B + Qwen3-30B-A3B, via OpenRouter) - no proprietary-model output in the dataset.

Usage

Serve a GGUF in-browser via wllama; each turn, build the system prompt from the library's ContextManager (persona + VIEW/CART/KNOWLEDGE) and advertise your tool schemas. See the project repo for the runtime wiring. Or fine-tune further from the transformers checkpoint (model.safetensors).
