  1. Model

    Gemini 4 Hydrogen

    Google's fast, efficient Gemini 4 model for everyday coding and agentic work, live the day it launched: $1.50 input and $7.50 output per million tokens, flat across its 1M-token window.

    See it: Gemini 4 Hydrogen
  2. Model

    Gemini 4 Carbon is live

    Google's strongest reasoning model, announced on 28 October, can now be called on the same key and balance. It spends more thinking tokens than Argon to verify its work, at the same $2 input and $10 output per million tokens until 30 November.

  3. Model

    Gemini Decision 1

    Google's decision model, live the day it launched: typed yes/no, choice and score questions about text, images, audio, video or PDFs, answered with probabilities for $0.10 per million input tokens.

  5. Site

    Model library as a price list

    Every model is now one row with context, input price, output price and the date it went live, so you can compare prices down a column instead of opening cards.

    See it: Model library as a price list
  6. Dashboard

    Clearer usage charts

    Daily spend, requests and tokens now have real axes and tooltips, and failed requests are drawn on top of successful ones so an error spike is visible at a glance.

  7. Site

    Agent templates

    Open-source starter apps you can clone and run on your CompanyFabric key, each with screenshots, the source on GitHub and an install command.

    See it: Agent templates

October 2026

18 updates

  1. Dashboard

    Scopes on API keys

    Choose what each key is allowed to do when you create it, so a key you hand to one tool cannot be used for everything on your account.

  2. Model

    Gemini 4 Carbon, tracked before launch

    Google has announced it but not opened the API. Its page carries the published launch price and will switch to live the day it can be called.

    See it: Gemini 4 Carbon, tracked before launch
  3. API

    Web search: POST /v1/search

    Search the web with the same key and get results billed per request. It is also available to agents as a web_search tool on the MCP server.

  4. API

    OpenAI Responses API: POST /v1/responses

    Code that calls client.responses.create, or the Vercel AI SDK's default OpenAI provider, now works unchanged against every model here.

    See it: Anthropic-compatible /v1/messages
  7. Dashboard

    See which model answered an auto request

    When you call companyfabric/auto, the usage page now names the model that actually served each request, so the price you paid is explained.

  8. API

    Long requests get up to 800 seconds

    Chat completions and messages requests can now run for as long as a deep reasoning model needs before the gateway gives up.

  9. Model

    MiMo-V2.6-Flash and MiMo-V2.6-Pro-Ultraspeed

    Budget caps and spend per API key

    Set a monthly limit on any key and see what each key has spent, so one runaway script cannot drain the whole balance.

  3. Billing

    Prompt-cache hits billed at the cache rate

    Input the provider serves from its cache is charged at the provider's lower cache price, and the usage page shows how much that saved you.

  4. Dashboard

    Every request, listed

    The usage page lists each request with its model, tokens and exact cost, alongside daily tokens split into cached input, fresh input and output.

  5. Dashboard

    Evals

    Run one agent setup against up to five models and get each answer graded per check, so choosing a model is a measurement instead of a guess.

    Send a situation and typed questions, get probabilities back. Launched with Jev, with a playground and starter examples.

    See it: Decisions: POST /v1/decisions

    See it: Bring your own provider keys
  14. Site

    Retired models keep their page

    When a provider withdraws a model, its page stays and says what replaced it and how to switch, so an old model id never leads to a dead end.

    OpenAI's GPT-6 flagship with a million-token window.

    See it: GPT-6 Astra
  16. Chat
