Quick Start

import SynorCompute

let client = SynorCompute(apiKey: "your-api-key")

// Matrix multiplication on GPU
let a = Tensor.random(shape: [512, 512])
let b = Tensor.random(shape: [512, 512])

Task {
    let result = try await client.matmul(a, b,
        precision: .fp16,
        processor: .gpu
    )

    if result.isSuccess {
        print("Time: \(result.executionTimeMs ?? 0)ms")
        print("Cost: $\(result.cost ?? 0)")
    }
}

Tensor Operations

// Create tensors
let zeros = Tensor.zeros(shape: [3, 3])
let ones = Tensor.ones(shape: [2, 2])
let random = Tensor.random(shape: [10, 10])
let randn = Tensor.randn(shape: [100])
let eye = Tensor.eye(size: 3)

// From array
let data: [Float] = [1, 2, 3, 4, 5, 6]
let tensor = Tensor(data: data, shape: [2, 3])

// Operations
let reshaped = tensor.reshape(to: [3, 2])
let transposed = tensor.transpose()

// Math
let mean = tensor.mean()
let sum = tensor.sum()
let std = tensor.std()

Async/Await API

// Matrix multiplication
let result = try await client.matmul(a, b,
    precision: .fp16,
    processor: .gpu,
    strategy: .speed
)

// Convolution
let conv = try await client.conv2d(input, kernel,
    stride: (1, 1),
    padding: (1, 1)
)

// Attention
let attention = try await client.attention(query, key, value,
    numHeads: 8,
    flash: true
)

LLM Inference

// Single response
let response = try await client.inference(
    model: "llama-3-70b",
    prompt: "Explain quantum computing",
    maxTokens: 512,
    temperature: 0.7
)
print(response.result ?? "")

// Streaming with AsyncSequence
for try await chunk in client.inferenceStream(
    model: "llama-3-70b",
    prompt: "Write a poem"
) {
    print(chunk, terminator: "")
}

Configuration

let config = SynorConfig(
    apiKey: "your-api-key",
    baseUrl: "https://api.synor.io/compute/v1",
    defaultProcessor: .gpu,
    defaultPrecision: .fp16,
    timeout: 30,
    debug: true
)

let client = SynorCompute(config: config)

SwiftUI Integration

import SwiftUI
import SynorCompute

struct ComputeView: View {
    @StateObject private var vm = ComputeViewModel()

    var body: some View {
        VStack {
            if vm.isLoading {
                ProgressView()
            } else if let result = vm.result {
                Text("Result: \(result)")
            }
            Button("Compute") {
                Task { await vm.compute() }
            }
        }
    }
}

@MainActor
class ComputeViewModel: ObservableObject {
    @Published var result: String?
    @Published var isLoading = false

    private let client = SynorCompute(apiKey: "your-api-key")

    func compute() async {
        isLoading = true
        defer { isLoading = false }

        do {
            let response = try await client.inference(
                model: "llama-3-70b",
                prompt: "Hello"
            )
            result = response.result
        } catch {
            result = "Error: \(error.localizedDescription)"
        }
    }
}

Error Handling

do {
    let result = try await client.matmul(a, b)
} catch let error as SynorError {
    switch error {
    case .apiError(let statusCode, let message):
        print("API Error \(statusCode): \(message)")
    case .networkError(let underlying):
        print("Network error: \(underlying)")
    case .invalidArgument(let message):
        print("Invalid argument: \(message)")
    }
} catch {
    print("Unexpected error: \(error)")
}

Types

// Processor types
enum ProcessorType: String, Codable {
    case cpu, gpu, tpu, npu, lpu, fpga, auto
}
