LFM2-1.2B-Tool rivals larger models in local browser benchmarks

Small models are finally becoming viable for complex autonomous agents, but current benchmarks like BFCL are failing to measure the multi-step reliability required for real-world tasks.

• –**Quantization Paradox:** While dense models like Qwen benefit from higher precision (Q6), MoE models like Gemma4 perform better at lower quantization (Q5) because increased inference speed is more valuable than precision for time-sensitive tasks like captchas.
• –**Fine-Tuning > Scale:** The 1.2B LFM2-Tool model's success proves that specialized tool-calling training allows a tiny model to outperform generalist models 8x its size.
• –**Modular Vision:** Offloading vision tasks to a dedicated 0.6B detector (Falcon Perception) instead of the main LLM is a significantly faster and more accurate architectural pattern for browser agents.
