Fiddler AI vs Turing

Fiddler AI — Infrastructure · Private · $100M raised · 2 of 2 figures sourced  |  Turing — Infrastructure · Private · $2.2B valuation · 3 of 3 figures sourced

Relationship

Fiddler Guardrails and Turing Intelligence Platform do comparable work on guardrails and safety; similar scale (private); ships agent platform and data service rather than the same layer.

Assembled from the recorded fields for this pair, not hand-checked. The comparison below is read from each company’s own profile.

No counterpart

Fiddler AI sells these in a stack layer with no product recorded for Turing yet — nothing on the other side to compare them against.

Application

Fiddler AI Governance, Risk Management, and ComplianceApplication

Governance module within the Fiddler AI Control Plane providing model inventories, policy enforcement and audit-ready reporting for regulatory compliance (e.g. EU AI Act) across an organization's AI systems.

Fiddler Agentic ObservabilityApplication

Tracing and monitoring module for multi-step agent workflows within the Fiddler AI Control Plane, tracking tool calls, reasoning steps and failures across an agent's execution.

Fiddler Continuous EvaluationsApplication

Ongoing automated evaluation module within the Fiddler AI Control Plane that re-scores production LLM/agent outputs against quality and safety metrics over time, not just at launch.

Fiddler GuardrailsApplication

Runtime safety layer within the Fiddler AI Control Plane that screens LLM/agent inputs and outputs for hallucination, toxicity, PII and jailbreak attempts before they reach users.

Developer tool

Fiddler AuditorDeveloper tool

Source-available library for red-teaming and robustness testing of LLMs, run independently of the hosted Fiddler platform. Fiddler's own page calls it "open-source"; its repository's actual licence is the Elastic License 2.0, which is not an OSI-approved open-source licence (it restricts offering the software as a competing hosted service), so it is recorded here by its real terms rather than the vendor's label.

Platform

Fiddler AIPlatform

AI observability platform: evaluation, monitoring and real-time guardrails for ML models and generative AI/agentic applications in production.

Turing sells these in a stack layer with no product recorded for Fiddler AI yet — nothing on the other side to compare them against.

Agent platform

Turing Intelligence PlatformAgent platform

An AI control plane that deploys, manages and scales enterprise AI agents across any model and any cloud, with governance and IP and sovereignty controls.

Data service

Off-the-shelf datasetsData service

A catalogue of pre-built, PhD-authored and expert-verified datasets — including CyberStrike, CompanyBench, EKWBench, SciCode and HLE++ — licensed to AI labs for reinforcement learning, benchmarking and model evaluation.

RL environmentsData service

Iterable UI and non-UI reinforcement-learning environments — including MCP server, computer-use and terminal environments — in which AI agents can be trained and evaluated on long-horizon workflows.

Turing Frontier AIData service

The training material a frontier lab runs on, sold as a service: 300+ reinforcement-learning environments, over a million curated tasks, and named benchmarks including CompanyBench, CyberStrike and Terminal-Bench 3.0, across software engineering, enterprise knowledge work and STEM.
