Main Technological Concepts and Features Discussed

Free Large Language Models (LLMs) and Providers
- Discussion about free access to various LLMs including models from Grok (a supplier with multiple models), Meta’s LLaMA (Russian-developed), and a European company.
- Models range from 7 billion to 70 billion parameters, with an upcoming LLaMA 3 model having 400 billion parameters still in training.
- Comparison with OpenAI’s GPT models (GPT-3.5 Turbo at 175B parameters and GPT-4 with undisclosed parameters).
- Emphasis on balancing model size, speed, and cost-efficiency, especially for phone survey applications where speed is more critical than deep intelligence.
Task Chains for Automated Phone Surveys Using LLMs
- Introduction of a “task chain” system that automates client phone surveys by importing client data (names, phone numbers, questions) from Excel or Google Sheets.
- The chain involves three main roles/bots:
  - Leader (Alexander): Manages client contact data and task delegation.
  - Telephone Survey Operator (Anna): Conducts the actual phone survey via synthesized voice calls.
  - Data Analyst Bot: Handles data reading and writing in spreadsheets.
- The process can be semi-automatic or fully automatic, with scheduled calls during working hours and feedback recorded back into the spreadsheet.
Integration with Telephony Service (Voximplant)
- Use of Voximplant as a telephony provider for making real phone calls.
- Ability to purchase phone numbers (in Russia and other regions) for outgoing and incoming calls at low cost (~$1/month).
- The system integrates bots with Voximplant via scripts and tokens for managing calls and voice synthesis.
Voice Synthesis and Recognition
- Use of voice synthesis services with a catalog of male and female voices supporting multiple languages.
- Challenges with voice synthesis and recognition latency (typically 4-5 seconds), causing delays in conversation flow.
- Discussion on asynchronous streaming of voice responses to reduce delay and improve naturalness.
- Potential for creating bots with different gender voices and customizing voice parameters.
Prompt Engineering and Role Definition
- Importance of clear, concise prompts and instructions to bots to avoid them “making up” data or generating irrelevant responses.
- Use of “fines” or penalties in prompts to enforce rule-following by the neural network (e.g., penalties for not calling the function or deviating from the script).
- Role-based instructions for each bot to ensure task clarity and stability of the chain.
Debugging and Stability Challenges
- Detailed discussion on debugging the chains, especially handling data reading/writing modes (read-only vs. editing).
- Issues with bots confusing parameters or modes leading to incorrect data handling.
- Strategies to simplify prompts and chain steps to improve reliability.
- Testing across different models (free smaller models vs. GPT-4) to find balance between cost and stability.
- Recommendations to start debugging on weaker/free models before moving to more powerful ones.
Use Cases and Applications
- Automated customer satisfaction surveys.
- HR-related surveys such as candidate screening.
- Potential to replace human operators for routine calls or to augment CRM systems.
- Flexibility to adapt the chain for different tasks or communication channels (phone, WhatsApp, Telegram).
Future Directions and Availability
- Plans to release the full task chain scripts, bot configurations, and documentation publicly (e.g., on Telegram channel and YouTube).
- Encouragement for community experimentation and feedback on successes and failures.
- Ongoing improvements in voice synthesis speed and chain automation.
