AIHubMix BYOK hops on DeepSeek V4.1 Flash, Solar Pro 4, and GPT-6 Astra

deepseek/deepseek-v4.1-flash already ships as DeepSeek V4.1 Flash (1M context, vision in, text out). It now also routes on aihubmix-byok as wire id deepseek-v4.1-flash. AIHubMix list rates on that hop are $0.155 / 1M input and $0.62 / 1M output (cache read $0.0031 / 1M). Catalog billed price on the hop is $0. Official Direct and OpenRouter BYOK hops stay; this is not a new listing id.

upstage/solar-pro4 is Solar Pro 4 (524K, tools, reasoning). AIHubMix BYOK list rates are $0.3 / 1M input and $1.2 / 1M output (cache read $0.06 / 1M); billed $0. OpenRouter BYOK stays. openai/gpt-6-astra is GPT-6 Astra (~1.05M, vision in, text out). AIHubMix BYOK list $10 / $50 per 1M (cache read $1 / 1M); billed $0. Platform aihubmix is still disabled (#3031) — BYOK twin only.

• App code — Vercel AI SDK or OpenAI SDK.
• Coding agent — anyr claude / anyr opencode / anyr codex (playbook).
• No code — playground.

Try it in the Vercel AI SDK. createAnyRouter() reads ANYROUTER_API_KEY:

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter()

const { text } = await generateText({
  model: anyrouter("deepseek/deepseek-v4.1-flash"),
  prompt: "Summarize this diff in three bullets.",
})
console.log(text)

Already on the OpenAI SDK? OpenAI SDK playbook:

import OpenAI from "openai"

const client = new OpenAI({
  baseURL: "https://anyrouter.dev/api/v1",
  apiKey: process.env.ANYROUTER_API_KEY,
})

const res = await client.chat.completions.create({
  model: "deepseek/deepseek-v4.1-flash",
  messages: [{ role: "user", content: "Hello" }],
})
console.log(res.choices[0]?.message.content)

curl https://anyrouter.dev/api/v1/chat/completions \
  -H "Authorization: Bearer $ANYROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek/deepseek-v4.1-flash","messages":[{"role":"user","content":"Hello"}]}'

Or launch a coding agent through the anyr CLI:

curl -fsSL https://anyrouter.dev/setup.sh | bash
anyr login
anyr claude --model "deepseek/deepseek-v4.1-flash"

curl -fsSL https://anyrouter.dev/setup.sh | bash
anyr login
anyr opencode --model "upstage/solar-pro4"

curl -fsSL https://anyrouter.dev/setup.sh | bash
anyr login
anyr codex --model "openai/gpt-6-astra"
