## EasyFunctionCall

EasyFunctionCall targets a very specific pain point in AI application development: giving language models the ability to call real APIs. Manually translating a large OpenAPI or Swagger document into function definitions is tedious, error-prone and expensive in tokens, especially when an API exposes dozens or hundreds of endpoints. The platform automates that translation, producing compact function-call parameters that AI models can consume without bloating the context window.

Because oversized schemas eat into the context budget on every request, EasyFunctionCall positions token optimisation as a core benefit. By generating leaner parameter structures, teams can fit more tools into a single model call and control inference costs as their API surface grows. The result is a faster path from an existing REST API to an AI agent or assistant that can actually take action.

The service is aimed at backend and AI engineers, integration specialists and product teams shipping autonomous workflows. It supports common model providers and works with standard specification formats, so it slots into existing documentation pipelines rather than replacing them.

**Pricing & Plans:** Freemium. A free tier is available to convert specifications and try the workflow, with paid plans for higher volumes and production use. Check the site for current limits.

- **OpenAPI and Swagger conversion:** Ingest standard OpenAPI or Swagger specifications and export function-call parameters ready for AI model tool use.
- **Token-efficient output:** Generates compact parameter definitions that reduce the context cost of exposing large API surfaces to language models.
- **Multi-model support:** Designed to work with popular model endpoints including ChatGPT/OpenAI, Claude, Gemini and Llama family models.
- **SaaS, no local setup:** A hosted web service, so teams can convert specs through the browser without maintaining parsing infrastructure.
- **Fits existing docs workflows:** Works from the API specifications development teams already maintain, avoiding duplicate schema authoring.

**Strengths:** Saves significant token budget when exposing many endpoints to a model; Removes repetitive manual function-schema authoring; Works with the OpenAPI/Swagger specs teams already have; Supports several major model providers

**Limitations:** Value depends on having a well-formed API specification to begin with; Developers still need to validate generated parameters against model-specific quirks; Hosted SaaS means API specs leave your environment unless handled carefully

## Invisible Technologies

Invisible Technologies occupies an unusual position in the AI industry: it is part software platform, part services organisation and part talent network. The company helps both frontier model labs and large enterprises move AI from prototype to production, and it credits itself with having contributed to the training of the majority of the world's leading models. Where a pure SaaS vendor would hand over a dashboard, Invisible combines tooling with people who actually do the work.

On the platform side, the offering is split into modular components. Neuron is the data layer that pulls messy, multi-source information into one governed place so it is usable by models. Atomic is the process builder that maps an operation visually and then runs the steps automatically, connecting systems and routing each task to the right AI or human. Synapse handles evaluation, testing AI systems against realistic work scenarios and your own criteria rather than generic benchmarks. Axon lets teams deploy agents that can plan through multi-step tasks, use tools and write code, with the versioning and audit trails needed for critical operations.

The human layer is what differentiates the model. Meridial, Invisible's expert network, draws on more than 24,000 vetted specialists organised by skill, language and domain, who can label training data, stress-test systems or handle the edge cases agents are not ready for. Typical engagements include back-office automation, computer vision, contact centre intelligence, demand forecasting and custom RL environments built by domain experts. Because every enterprise's friction with AI is different, the company positions itself as a bridge between a general model and a specific operational reality.

**Pricing & Plans:** Pricing is not published. Invisible quotes per engagement based on data volume, model complexity and the level of expert involvement, so prospective customers book a demo or contact sales for a tailored proposal.

- **Training data for frontier models:** Produces research-grade datasets, including multilingual and domain-specific evaluation data, backed by a large vetted expert network.
- **Model evaluation and testing:** Runs AI systems through realistic task scenarios with custom criteria covering accuracy, safety, tone and domain fit, comparing models side by side.
- **Deployable AI agents:** Builds governed agents that handle multi-step work, use tools and write code, with versioning, per-customer separation and full audit trails.
- **Process automation for back office:** Maps how work actually flows through an organisation, then automates steps gradually, routing to AI or humans as needed.
- **Data preparation and governance:** Consolidates scattered enterprise data into one governed, AI-ready layer so models and workflows know what to use and where it lives.

**Strengths:** Combines platform tooling with a 24,000+ expert network, so projects are not limited to what software alone can do; Deep experience training and evaluating frontier models, with direct relationships across major AI labs; Modular components let enterprises start with one problem area instead of a full platform migration
