Model overview
**This is LiquidAI's LFM2.5-2.6B with its refusal behavior aggressively reduced.** It keeps the compact 2.7B hybrid architecture, but answers requests the stock post-trained model refused. In our tests, refusals fell from 132/842 to 8/842 and from 19/126 to 1/126 on a held-out set, while the average change across five public capability benchmarks was only -0.50 percentage points. **PHILADELPHIA CLASS** includes the full BF16 checkpoint as one `model.safetensors` file plus a tested BF16 GGUF for llama.cpp. Both retain LFM2.5's tokenizer, reasoning chat template, and 128K configured context. This repository redistributes modified model weight files derived from `LiquidAI/LFM2.5-2.6B` at revision `dca1825886789bd40b94368f53b1d9ada4c94598`. The local untouched checkpoint was verified against all 11 files in that Hub revision before release preparation.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
