Upwork Data Shows AI and Humans Are Better Together

Upwork CEO Says AI Won't Eliminate Human Work

If AI agents were employees, a major new study suggests you shouldn't leave them unsupervised. Upwork has released its "Human+Agent Productivity Index" (HAPI), calling it the first large-scale analysis of how human experts significantly boost AI performance on real client projects.

The findings directly challenge the notion that AI agents can operate effectively on their own.

The core insight from the research is clear: AI agents aren't yet fully capable on their own, but they become dramatically more effective when paired with human professionals.

Upwork's CTO, Andrew Rabinovich, stated,

Why This Study is Different

Unlike most AI benchmarks that use synthetic or academic tests, HAPI is built on data from over 300 real, paid projects completed on Upwork's platform. This provides a rare look at how AI performs on authentic work rather than controlled experiments.

The Human-AI Performance Gap

The study revealed a significant performance gap:

• AI Alone: Agents (including those powered by top models like GPT-5 and Claude Sonnet 4) frequently missed details, misread instructions, and failed at basic formatting when working independently.

• Human + AI: When human experts reviewed and corrected AI output, completion rates increased by up to 70%. Human reviewers typically spent just 20 minutes per feedback cycle to achieve these dramatic improvements.

Task-Specific Results

The human-AI collaboration showed particularly strong results in:

• Writing, translation, and marketing tasks: 17 percentage point improvement

• Engineering and architecture jobs: 23 percentage point improvement

• Technical tasks like basic coding: AI performed best alone, where the rules are clear

• Creative or subjective work: Humans provided essential judgment and nuance

Economic Implications

The research also examined the cost-effectiveness of different approaches:

• Low-value tasks: AI-only can be cost-effective despite imperfections

• Mid-value projects: Human-AI collaboration delivers the best value

• High-value/complex work: Full human involvement remains most reliable

The Future of Work is Collaborative

Upwork is already seeing a 53% year-over-year increase in AI-related activity on its platform.

The company is developing "Uma," a meta-orchestration agent designed to intelligently manage collaboration between humans and AI, determining which parts of a job an agent can handle and which require human expertise.

This shift is creating new opportunities for professionals. As simpler tasks become automated, jobs are evolving to become more complex, potentially increasing both the amount of work and earnings for skilled freelancers who can effectively collaborate with AI systems.

Salesforce's New Simulation Environment for Agent Training

Salesforce AI Research has introduced a new simulation platform designed to train AI agents for business environments. Called eVerse, this virtual training environment uses synthetic data generation, stress testing, and reinforcement learning to prepare AI agents for real-world enterprise applications.

The platform represents another step toward Salesforce's vision of Enterprise General Intelligence (EGI) - AI systems specifically optimized for business use with exceptional reliability.

According to Silvio Savarese, Salesforce's Chief Scientist, current AI systems face a critical challenge:

Solving the "Jagged Intelligence" Problem

A key issue eVerse addresses is what Salesforce calls "jagged intelligence", where AI systems excel at complex tasks but unexpectedly fail at simpler ones requiring common sense.

Savarese notes that simply training larger models has reached a point of diminishing returns. Instead, Salesforce is focusing on learning through experience, allowing AI to incorporate feedback from simulated environments before deployment.

How eVerse Works

The platform creates realistic enterprise scenarios using synthetic data that mimics actual customer information. Teams can:

• Test agents in controlled virtual environments

• Measure failure modes and successful outcomes

• Iterate until agents achieve production-ready performance

Salesforce used eVerse to develop Agentforce Voice, their voice-enabled agent system. Before launch, the technology underwent thousands of simulated conversations, testing scenarios like background noise, accents, and crosstalk.

Real-World Application: Healthcare Billing

UCSF Health has piloted eVerse to improve its patient billing operations. The hospital handles approximately 2.5 million outpatient visits annually, generating about 9,000 billing inquiries monthly.

According to Dr. Sara Murray, UCSF's Chief Health AI Officer, their initial AI agent could handle 70% of inquiries but required human intervention for the remaining 30%.

"Through eVerse's Healthcare Learning Engine, we've been able to iteratively teach the AI agent to now handle approximately 80% of billing inquiries," Murray reported.

This represents significant time savings for human staff who previously spent thousands of hours annually on billing calls.

The eVerse platform demonstrates Salesforce's approach to creating more reliable enterprise AI by emphasizing rigorous simulation and iterative improvement rather than simply scaling model size.

AWS Bets on AI Agents to Streamline Consulting

Amazon Web Services has introduced a new AI-powered solution designed to dramatically accelerate the process of moving legacy software to the cloud.

The Professional Services Delivery Agent uses artificial intelligence to automate key migration tasks that traditionally required extensive manual effort.

How the AI Migration Agent Works

The system begins by analyzing project requirements from simple inputs like architectural diagrams or meeting notes.

Within hours, it can generate comprehensive project proposals and work descriptions, tasks that previously took weeks to complete. AWS Professional Services consultants oversee the process to ensure outputs meet quality standards.

The platform employs specialized sub-agents that handle different aspects of the migration process:

• Writing new code

• Testing functionality

• Deploying applications
  For specific legacy systems, including COBOL mainframes, VMware workloads, and .NET applications, the system automatically activates AWS Transform to handle the conversion process.

Solving the Dependency Challenge

One of the most complex aspects of software migration - managing dependencies - represents a key focus for the AI agent.

The system automatically maps dependencies, creates migration plans, and generates necessary code to replace software components that applications need to function properly.

According to AWS Vice President Francessca Vasquez, "This agent incorporates a knowledge base of learnings from thousands of migrations AWS ProServe has completed," giving it substantial institutional knowledge to draw upon.

Competitive Landscape

AWS joins other major cloud providers in developing AI-powered migration tools:

• Google utilizes its CogniPort agent to transition workloads to Axion processors

• Microsoft integrates migration capabilities into GitHub Copilot for Azure transitions

The technology has demonstrated significant efficiency gains in pilot projects, reducing migration timelines from months to mere days.

This automation addresses a major barrier for companies hesitant to modernize legacy systems, potentially accelerating cloud adoption across enterprises still relying on older software infrastructure.
