The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1OpenAI Function Calling Fundamentals: API Configuration and First Calls (Python Tools, OpenAI SDK)
Discover the evolutions of function calling 2026 via the OpenAI API, configure your Python environment with the official SDK, perform your first simple function calls by testing adapted JSON schemas, analyze structured responses from the GPT model, and produce a first basic agent deliverable connected to an external weather API to validate real-time data flows.
Module 2Advanced OpenAI Function Calling: Complex Schemas and Parallel Tools (JSON Schema Methods, Parallel Tool Calls)
Dive into advanced JSON schemas for function calling 2026, implement parallel calls to multiple tools with the o1-preview model, test use cases like cross-data analysis via third-party APIs, debug parsing errors live, and generate a virtual assistant prototype handling multiple functions simultaneously for concrete business scenarios.
Module 3OpenAI Function Calling Integration: Enterprise Workflows and Security (LangChain Frameworks, OAuth Authentication)
Integrate function calling 2026 into professional workflows using LangChain and LlamaIndex, secure calls with tokens and OAuth2, develop a RAG agent enhanced by external functions for augmented search, simulate integrations with SQL databases, and deliver an interactive dashboard demonstrating AI call traceability in a controlled environment.
Module 4OpenAI Function Calling Optimization: Performance and Scalability (Fine-Tuning, Caching, Prometheus Monitoring)
Optimize function calling 2026 performance through targeted fine-tuning and intelligent caching, monitor costs and latencies with Prometheus and Grafana, scale agents for high loads via Docker, test resilience to network errors, and produce a quantified optimization report on a complete CRM automation case.
Module 5OpenAI Function Calling Deployment: Production and Business Cases (Vercel, AWS Lambda, Certifying Projects)
Deploy your function calling 2026 agents in production on Vercel or AWS Lambda, integrate with enterprise stacks like Salesforce or custom CRMs, review AI governance best practices, finalize a personal certifying capstone project, and benefit from a post-training audit for immediate and cost-effective implementation.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
