#4418 cdc82e4 Thanks @IMax153! - Support per-request HTTP client transformations in the OpenAi AI integration package.

For example:

import { Completions } from "@effect/ai"
import {
  OpenAiClient,
  OpenAiCompletions,
  OpenAiConfig
} from "@effect/ai-openai"
import { HttpClient, HttpClientRequest } from "@effect/platform"
import { NodeHttpClient } from "@effect/platform-node"
import { Config, Effect, Layer } from "effect"

const OpenAi = OpenAiClient.layerConfig({
  apiKey: Config.redacted("OPENAI_API_KEY")
}).pipe(Layer.provide(NodeHttpClient.layerUndici))

const Gpt4oCompletions = OpenAiCompletions.layer({
  model: "gpt-4o"
}).pipe(Layer.provide(OpenAi))

const program = Effect.gen(function* () {
  const completions = yield* Completions.Completions

  yield* completions.create("Tell me a dad joke").pipe(
    // Per-request HTTP client transforms which are only applied if
    // the OpenAi provider is in use
    OpenAiConfig.withClientTransform(
      HttpClient.mapRequest(
        HttpClientRequest.setHeader("x-dad-jokes", "are-awesome")
      )
    )
  )
})

program.pipe(Effect.provide(Gpt4oCompletions), Effect.runPromise)

Patch Changes

#4412 e30f132 Thanks @KhraksMamtsov! - Fix STM unification

#4403 33fa667 Thanks @gcanti! - Duration: fix format output when the input is zero.

Before

import { Duration } from "effect"

console.log(Duration.format(Duration.zero))
// Output: ""

After

import { Duration } from "effect"

console.log(Duration.format(Duration.zero))
// Output: "0"

#4411 87f5f28 Thanks @gcanti! - Enhance TagClass and ReferenceClass to enforce key type narrowing, closes #4409.

The key property in TagClass and ReferenceClass now correctly retains its specific string value, just like in Effect.Service

import { Context, Effect } from "effect"

// -------------------------------------------------------------------------------------
// `key` field
// -------------------------------------------------------------------------------------

class A extends Effect.Service<A>()("A", { succeed: { a: "value" } }) {}

// $ExpectType "A"
A.key

class B extends Context.Tag("B")<B, { a: "value" }>() {}

// $ExpectType "B"
B.key

class C extends Context.Reference<C>()("C", { defaultValue: () => 0 }) {}

// $ExpectType "C"
C.key

#4397 4dbd170 Thanks @thewilkybarkid! - Make Array.makeBy dual
