What does GPT2Giga Proxy do?

GPT2Giga Proxy runs and configures a proxy that maps OpenAI API and Anthropic Messages API requests to GigaChat, allowing you to use GigaChat in existing applications built for OpenAI or Anthropic without rewriting the client integration.

When should I use GPT2Giga Proxy?

Use GPT2Giga Proxy when you need compatibility, migration, or proxy deployment — specifically when you want to plug GigaChat into existing OpenAI-compatible or Anthropic-compatible applications without rewriting the client integration. Do not use it for new native applications; build directly against GigaChat APIs instead.

What deployment options does GPT2Giga Proxy support?

GPT2Giga Proxy supports local development, Docker, and production deployments, with configuration options for proxy authentication, GigaChat authentication, and API family preservation (OpenAI or Anthropic).

Does GPT2Giga Proxy support streaming and model routing?

Yes, GPT2Giga Proxy covers streaming and model routing behavior, along with production hardening, proxy authentication, and pass-through authentication modes.

Overview

GPT2Giga Proxy

Runs and configures the gpt2giga proxy, mapping OpenAI and Anthropic API requests to GigaChat so an existing compatible client can switch backends without rewriting its integration. Use it for compatibility, migration, or proxy-deployment tasks plugging GigaChat into an existing OpenAI- or Anthropic-compatible app; not for a new native GigaChat app.

What it does

Runs and configures the gpt2giga proxy, which maps OpenAI API and Anthropic Messages API requests to GigaChat so an existing OpenAI-compatible or Anthropic-compatible client can talk to GigaChat without rewriting its integration. Covers local or Docker startup, .env and CLI configuration, both compatible endpoint families, proxy auth kept separate from GigaChat auth (or pass-token mode when the client should carry its own GigaChat credentials), streaming and model-routing behavior, and production hardening - enabling proxy API-key auth and avoiding dev-only endpoints once live.

When to use - and when NOT to

Use it for compatibility, migration, or proxy-deployment tasks: plugging GigaChat into an app that already speaks OpenAI or Anthropic, without touching the client's SDK integration. It treats itself explicitly as a compatibility layer, not the default choice for a new, native GigaChat app - and it doesn't teach raw GigaChat SDK usage, which belongs to a separate gigachat-sdk-* skill.

Inputs and outputs

Input: an existing OpenAI- or Anthropic-compatible client needing to reach GigaChat, plus a deployment target (local, Docker, or production). Output: a running proxy pointed at by the client's existing base URL, with proxy auth configured, and an explicit statement of which API family - OpenAI or Anthropic - is being preserved and where behavior diverges from the native API, since outer orchestration still owns full multi-step tool execution.

Integrations

References references/config.md for env vars, ports, auth, and startup, and references/compatibility.md for endpoint compatibility and client behavior. Complements a separate gigachat-sdk-* skill for direct GigaChat SDK usage.

Who it's for

Developers who need to point an existing OpenAI- or Anthropic-compatible application at GigaChat without rewriting its client integration.
