What is Large Language Model? (LLM)
2 min read · Bolcho
The AI 'brain' that decides what the agent says next, based on the conversation, the prompt, and any knowledge it looks up.
Large Language Model explained
A large language model reads the transcript so far plus the system prompt and generates the next thing to say. In a voice agent it also decides when to call a tool (book, transfer, look up) and when to hand off to a human.
Bolcho routes across multiple LLMs (GPT, Claude, Gemini, Grok, Sarvam) with failover and prompt caching, so you get the best model for the task at the lowest cost, and calls don't drop if one provider has an outage.
Why it matters for voice AI in India
Understanding large language model helps you build voice agents that actually work for Indian callers, genuine languages, low latency, and near-cost pricing. Bolcho is built around exactly these fundamentals.
