> ## Documentation Index > Fetch the complete documentation index at: https://phaseo.app/docs/llms.txt > Use this file to discover all available pages before exploring further. > ## Agent Instructions > Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request. > Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance. > For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code. > The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust. > Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool. > Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first.

The **Phaseo Platform** gives you a complete view of the global AI landscape - from the newest models and providers to performance benchmarks, pricing, and real world usage insights. Whether you’re a developer choosing what model to use for your newest product, a researcher analysing benchmark results, or a contributor helping expand the database, this section will help you make the most of what Phaseo offers. *** ## What you can do > [card] [Discover Organisations](https://phaseo.app/docs/v1/exploring/organisations.md) > > See what models are offered by organisations, as well as their latest > releases and how they stack up. > [card] [Explore Models](https://phaseo.app/docs/v1/exploring/models.md) > > View detailed model pages with key information like capabilities, > pricing, benchmark results, and real world performance metrics. > [card] [Compare Benchmarks](https://phaseo.app/docs/v1/exploring/benchmarks.md) > > See how models perform across common benchmark datasets and tasks. > [card] [Analyse Pricing & Performance](https://phaseo.app/docs/v1/exploring/pricing-performance.md) > > Compare model costs and token efficiency to find the right balance for > your use case. *** ## Data structure Phaseo collects and organises data in several key categories: | Category | Description | | - | - | | **[Organisations](https://phaseo.app/docs/v1/exploring/organisations.md)** | The companies or research labs that develop and publish models. | | **[Models](https://phaseo.app/docs/v1/exploring/models.md)** | The individual models that are released by the organisations. | | **[Benchmarks](https://phaseo.app/docs/v1/exploring/benchmarks.md)** | The standardised tests that organisations use to evaluate model performance. | | **[API Providers](https://phaseo.app/docs/v1/exploring/api-providers.md)** | The platforms that offer programmatic access to models. | | **[Pricing](https://phaseo.app/docs/v1/exploring/pricing-performance.md)** | Detailed cost breakdowns per model, measured per token, image, or generation. | | **[Subscription Plans](https://phaseo.app/docs/v1/exploring/subscription-plans.md)** | Information on different pricing tiers and their included features or limits. | Each of these categories is discussed in the documentation to help you navigate these pages and get the most out of the data. *** ## How Phaseo collects and updates data Phaseo is powered by a vast, fully open database - built and maintained through a mix of automation and incredible community effort. While we have automated systems that track updates across providers and models, human contribution is the back bone of the project and is what keeps it running smoothly. When updates do occur: * 🧩 New models are added swiftly and documented with as much detail as possible. * 🔄 Provider changes - from pricing to endpoint tweaks - are continuously monitored and reviewed. * Community catalog reports are reviewed through GitHub issues. Maintainers apply approved changes through the database editor. You can contribute corrections or additions yourself, check out the [Contributing guide](https://phaseo.app/docs/v1/contributing/overview.md) for details. Phaseo is only as strong as the community behind it - and together, we’re building the most accurate and transparent record of AI progress in the world. *** ## Interpreting data on Phaseo All data on Phaseo has been normalised for consistency: * **Dates** should always be formatted as `DD MMM YYYY` (e.g. `01 Jan 2022`). * **Prices** are displayed in USD by default, normalised per 1 million tokens where applicable or appropriate units. * **Performance scores** are standardised to a common scale where possible. * **Model families** group together related models (e.g., GPT-5, Claude 4, Gemini 2.5, etc.). *** ## Example use cases Here are some examples of how you might use Phaseo: | Goal | Example | | - | - | | Compare two models | “Which performs better on GPQA - Claude 4.5 Sonnet or GPT-5?” | | Find the cheapest model for a task | “What’s the most cost-efficient model for summarisation?” | | Analyse benchmark trends | “How have reasoning models improved on GPQA over the last year?” | | Explore API access | “Which providers currently support JSON mode?” | | Identify gaps for contribution | “Which models are missing key benchmarks or metadata?” | *** ## Next steps > [card] [Explore Models](https://phaseo.app/models) > > Explore the latest models in the database and dive deeper into how each > one performs. > [card] [Learn About Benchmarks](https://phaseo.app/docs/v1/exploring/benchmarks.md) > > Understand what benchmarks measure and how we can interpret results. *** This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
