Enterprise AI with Claude in Turkey - The Unified AI API Platform

What Is Anthropic Claude?

About the technology and the company behind the model

Anthropic was founded in 2021 by former OpenAI researchers Dario and Daniela Amodei with AI safety as its founding mission. Its Constitutional AI approach trains models against an explicit set of written principles, which is why Claude has earned a reputation for low hallucination rates and predictable behavior — and why it has become one of the most trusted model families in enterprise AI.

At the top of today's lineup sits Claude Fable 5, Anthropic's first Mythos-class model and the smartest generally available Claude to date: a 1-million-token context window, up to 128K tokens of output, and always-on reasoning built for autonomous knowledge work and coding. It is joined by the new Claude Sonnet 5 with adaptive thinking and effort levels, Claude Opus 4.8 — the most powerful member of the Opus family — the balanced favorite Sonnet 4.6, and the fast, economical Haiku 4.5.

For teams that need Claude API access from Turkey, Onysoft AI Gateway — operated by Izmir-based Onysoft Veri Merkezi A.S. — offers Claude alongside 708+ models behind a single OpenAI-compatible API. You top up in Turkish Lira and pay as you go at the current TCMB exchange rate, with no subscription. Corporate e-invoices, a KVKK-compliant platform and 24/7 support come as standard. Existing OpenAI SDK code works with nothing more than a base_url change, and the Playground lets you test every model right in the browser.

Anthropic keeps scaling capability and safety together with every generation. Our goal at Onysoft is to bring each new Claude model to developers and enterprises in Turkey at up-to-date TL pricing from day one.
