A Deep Dive into the 2025 State of AI Report
As generative AI moves from labs into industry deep waters, the key challenge facing every tech enterprise is no longer technical feasibility, but how to translate AI's potential into tangible product value. The 2025 State of AI Report, published by ICONIQ Capital, surveys over 300 software executives and introduces a Builder’s Playbook for the Generative AI Era, offering a full-cycle blueprint from planning to production. This report not only maps out the current technological landscape but also pinpoints the critical vectors of evolution, providing actionable frameworks for builders navigating the AI frontier.
The Technology Stack Landscape: Infrastructure Blueprint for Generative AI
The deployment of generative AI hinges on a robust stack of tools. Just as constructing a house requires a full set of materials, building AI products requires tools spanning training, development, inference, and monitoring. While the current ecosystem has stabilized to some extent, it remains in rapid flux.
In model training and fine-tuning, PyTorch and TensorFlow dominate, jointly commanding over 50% market share, due to their rich ecosystems and community momentum. AWS SageMaker and OpenAI’s fine-tuning services follow, appealing to teams seeking low-code, out-of-the-box solutions. Hugging Face and Databricks Mosaic are gaining traction rapidly—the former known for its open model hub and user-friendly tuning utilities, the latter for integrating model workflows within data lake architectures—signaling a new wave of open-source and cloud-native convergence.
In application development, LangChain and Hugging Face lead the pack, powering applications such as chatbots and document intelligence, with a combined penetration exceeding 60%. Security reinforcement has become critical: 30% of companies now employ tools like Guardrails to constrain model output and filter sensitive content. Meanwhile, high-abstraction tools like Vercel AI SDK are lowering the entry barrier for developers, enabling fast prototyping without deep understanding of model internals.
For monitoring and observability, the industry is transitioning from legacy APMs (e.g., Datadog, New Relic) to AI-native platforms. While half still rely on traditional tools, newer solutions like LangSmith and Weights & Biases—each with ~17% adoption—offer better support for tracking prompt-output mappings and behavioral drift. However, 10% of respondents remain unaware of what monitoring stack is in use, reflecting gaps that may create downstream risk.
Inference optimization shows a heavy reliance on NVIDIA—over 60% use TensorRT with Triton to boost throughput and reduce GPU cost. Among non-NVIDIA solutions, ONNX Runtime leads (18%), offering cross-platform flexibility. Still, 17% of firms lack any inference optimization, risking latency and cost issues under load.
In model hosting and vector databases, zero-deployment APIs from foundation model vendors are the dominant hosting choice, followed by AWS Bedrock and Google Vertex for their multi-cloud advantages. In vector databases, Elastic and Pinecone lead on search maturity, while Redis and ClickHouse address needs for real-time and cost-sensitive applications.
Model Strategy: A Gradient from API Dependence to Customization
Choosing the right model and usage approach is central to product success. The report identifies a clear gradient of model strategies, ranging from API usage to fine-tuning and full in-house model development.
Third-party APIs remain the norm: 80% of companies use external APIs (e.g., OpenAI, Anthropic), far surpassing those doing fine-tuning (61%) or developing models in-house (32%). For most, APIs offer the fastest way to test ideas with minimal investment—ideal for early-stage exploration. However, high-growth companies show bolder strategies: 77% fine-tune models, and 54% build their own, significantly above the average. As products scale, generic models hit their accuracy ceilings, driving demand for domain-specific customization and IP-based differentiation.
RAG (Retrieval-Augmented Generation) and fine-tuning are the most widely adopted techniques (each ~67%). RAG boosts factual accuracy by injecting external knowledge—critical in legal or medical contexts—while fine-tuning adjusts models to domain-specific language and logic using minimal data. Only 31% conduct full pretraining, as it remains prohibitively expensive and typically reserved for hyperscalers.
Infrastructure choices reflect a preference for cloud-native: 68% run fully in the cloud, 64% rely on external APIs, only 23% use hybrid deployments, and a mere 8% run fully on-prem. This points to a cost-sensitive model where renting compute outpaces building in-house capacity.
Model selection criteria diverge by use case. For external-facing products, accuracy (77%) is paramount, followed by cost (57%) and tunability (41%). For internal tools, cost (72%) leads, followed by privacy and compliance. This dual standard shows that AI is a stickier value proposition for external engagement, and an efficiency lever internally.
Implementation Challenges: From Technical Hurdles to Business Proof
Getting from “0 to 1” is relatively straightforward—going from “1 to 100” is where most struggle. The report outlines three primary obstacles:
-
Hallucination: The top issue. When uncertain, models fabricate plausible but incorrect outputs—unacceptable in sensitive domains like contracts or diagnostics. RAG can mitigate but not fully solve this.
-
Explainability and trust: The “black-box” nature of AI undermines user confidence, especially in domains like finance or autonomous driving where the rationale often matters more than the output itself.
-
ROI justification: AI investment is ongoing (compute, talent, data), but returns are often indirect (e.g., productivity gains). Only 55% of companies can currently track ROI—highlighting a major decision-making bottleneck.
Monitoring maturity scales with product stage: over 75% of GA or scaling-stage products employ advanced or automated monitoring (e.g., drift detection, feedback loops, auto-retraining). In contrast, many pre-launch products rely on minimal or no monitoring, risking failure at scale.
Agentic Workflows: The Rise of Automation-First Systems
As discrete AI capabilities mature, focus is shifting toward end-to-end task automation—enter the age of Agentic Workflows. AI agents autonomously interpret user intent, decompose tasks, and orchestrate tool usage (e.g., fetching data, writing reports, sending emails), solving the classic problem of “data-rich, insight-poor” operations.
High-growth firms are leading the charge: 47% have deployed agents in production vs. 23% overall. This leap moves AI from augmenting to replacing human labor, especially in repeatable processes like customer support, logistics, or finance.
Notably, 80% of AI-native companies use Agentic Workflows, signaling a paradigm shift from “prompt-response” to workflow orchestration. Tomorrow’s AI will behave more like a “digital coworker” than a reactive plugin.
Costs and Resources: From Burn Rate to Operational Discipline
The “burn rate” of generative AI is well understood, but as maturity rises, companies are moving toward proactive cost optimization.
AI-enabled firms now allocate 15%-25% of R&D budgets to AI (up from 10%-15% in 2024). Crucially, budget structures shift with product maturity: early on, talent accounts for 57% of spend (hiring ML engineers, data scientists), but at scale, this drops to 36%, with inference (up to 22%) and storage (up to 12%) growing substantially. Inference becomes the dominant cost center in operational phases.
Pain points are predictable: 70% cite API usage fees as hardest to manage (due to volume-based pricing), followed by inference (49%) and fine-tuning (48%). In response, cost strategies include:
-
41% shift to open-source models to avoid API fees,
-
37% optimize inference to maximize hardware utilization,
-
32% use quantization/distillation to compress model size and reduce runtime costs.
Internal Productivity: How AI Is Rewiring Organizations
Beyond external products, internal AI adoption is reshaping organizational efficiency. Budgets for internal AI are expected to nearly double in 2025, reaching 1%-8% of revenue. Large enterprises (> $500M) are reallocating from R&D and operations, and 27% are tapping into HR budgets—substituting headcount with automation.
Yet tool penetration lags actual usage: While 70% of employees have access to AI tools, only 50% use them regularly—dropping to 44% in enterprises > $1B revenue. This reflects poor tool-job fit and insufficient user training or change management.
Top internal use cases: code generation, content creation, and knowledge retrieval. High-growth firms generate 33% of code via AI—vs. 27% for others—making AI a central force in development velocity.
ROI metrics prioritize productivity gains (75%), then cost savings (51%), with revenue growth (20%) trailing. This confirms AI’s core internal role is cost and time efficiency.
