typesafe: base URL and model from the environment by hallelx2 · Pull Request #18 · hallelx2/llmgate

hallelx2 · 2026-09-20T00:47:43Z

TYPESAFE_BASE_URL / TYPESAFE_MODEL are read when Config.BaseURL / Config.Model are empty — the names TypeSafe's SDKs use. Lets the bench commands and anything else that only sets a key point at a TypeSafe-compatible gateway (Vercel AI Gateway: https://ai-gateway.vercel.sh/typesafe, model typesafe-ai/jev) without a code change. Tests green.

Summary by Sourcery

Enable TypeSafe clients to target compatible gateways and models through environment configuration.

New Features:

Support configuring the TypeSafe base URL and model through TYPESAFE_BASE_URL and TYPESAFE_MODEL environment variables when configuration values are unset.

Enhancements:

Add pricing information for the typesafe-ai/jev model identifier.

Summary by CodeRabbit

New Features
- Configure the Typesafe service base URL and model through the TYPESAFE_BASE_URL and TYPESAFE_MODEL environment variables.
- Added support for the typesafe-ai/jev model.
Pricing
- The typesafe-ai/jev model is priced at $0.042 per million input tokens, with no charge for output tokens.

…s them empty The names TypeSafe's own SDKs honour, and what a gateway speaking the TypeSafe shape asks for — Vercel AI Gateway serves Jev at https://ai-gateway.vercel.sh/typesafe as typesafe-ai/jev with an AI Gateway key.

📝 Walkthrough

Walkthrough

The PR adds environment-variable fallbacks for TypeSafe base URL and model settings. It also adds typesafe-ai/jev to the System One pricing table.

Changes

TypeSafe environment configuration

Layer / File(s)	Summary
Environment configuration fallback `judge/typesafe/typesafe.go`	Adds exported environment-variable constants. `New` reads them when the corresponding configuration fields are empty, then applies existing defaults and validation.

System One pricing

Layer / File(s)	Summary
TypeSafe Jev pricing `pricing/systemone.go`	Adds the `typesafe-ai/jev` alias with a $0.042 per million input-token rate and a $0 output-token rate.
