I have a NLP task for which Gemma4 31B is best suited. Using it with Cerebras Cloud works but hits daily limit very quickly and I dont have hardware to deploy locally. Google AI Studio also give up on limits. How can use this model only? ---

![Gemma runs free on many clouds - swap one base_url](https://onehack.st/uploads/default/original/3X/6/8/686efcd31b3af203332bb4b22c2bfc9f068284ee.jpeg) Gemma is **open-weights** — Cerebras and Google don’t own it, they’re just two hosts among many. That “daily limit” is one provider’s throttle, not the model’s. The same Gemma runs on a dozen clouds behind the **standard chat API** , so you hop hosts by changing **one `base_url`** — and stacked free tiers add up to one big daily quota. (Reply above said Ollama — that’s _local_, which you can’t do; this is all cloud, no GPU.) ### 🔌 The one-line swap — same code, any host ```python from openai import OpenAI c = OpenAI(base_url="https://openrouter.ai/api/v1", api_key="YOUR_KEY") c.chat.completions.create( model="google/gemma-3-27b-it:free", messages=[{"role": "user", "content": "..."}]) ``` ↳ change **`base_url` + `api_key` + `model`** → you’re on a different host. Nothing else in your code moves. ### 🗺 Where Gemma runs free (no card) — ranked by daily headroom | Host | Free / day | `model` | `base_url` | | --- | --- | --- | --- | | **Google AI Studio** ⚠ not in EU/UK | ~14,400 req | `gemma-3-27b-it` | `generativelanguage.googleapis.com/v1beta/openai/` | | ~~**Cerebras**~~ ⚠ card required now | $5 credit, then pay-per-token | `gemma-4-31b` \* | `api.cerebras.ai/v1` | | **OpenRouter** 🔀 also the rotator | 50 → ~1k req † | `google/gemma-3-27b-it:free` | `openrouter.ai/api/v1` | | **NVIDIA NIM** | ~40 RPM · no hard cap | `google/gemma-3-27b-it` | `integrate.api.nvidia.com/v1` | \* preview slot — verify the live id first · † 50/day jumps to ~1,000/day after a one-time $10 credit (the `:free` calls don’t spend it) You’re already on **Cerebras + Google** — so just **add OpenRouter + NVIDIA** , then fuse all four into one quota 👇 ### 🔀 Make N free tiers act as ONE big quota - **OpenRouter** — one key already fans out across every upstream serving free Gemma, with built-in failover. Zero setup — make it your default tap. → [https://openrouter.ai/google/gemma-3-27b-it:free](https://openrouter.ai/google/gemma-3-27b-it:free) - **LiteLLM proxy** (self-host) — the real stacker: list `model_name: gemma` once **per provider** (your Google / Cerebras / OpenRouter / NVIDIA keys), add a `fallbacks` line → it round-robins and skips any key the moment it `429`s.

Google AI Studio, OpenRouter, and NVIDIA below are still genuinely free, no card. > - **Your “Gemma 4 31B”:** Cerebras / NVIDIA / OpenRouter carry the newer v4, but preview/`:free` slots rotate — **verify the exact id live** (filter [https://openrouter.ai/models](https://openrouter.ai/models) by $0). Everywhere else, **`gemma-3-27b-it` is the guaranteed drop-in** — same request body. > - **IDs differ by host:** `google/` prefix on OpenRouter/NVIDIA (OpenRouter adds `:free`) vs **bare** id on Google/Cerebras. Only `base_url` + `key` + `model` change. > - **Dead ends — don’t waste time:** Groq, Together, and GitHub Models have **no Gemma** in their catalogs anymore. > - **Google’s `/openai/` path** sometimes serves Gemini only — if a `gemma-*` id 404s, use Google’s native `genai` SDK, or just reach Google’s Gemma quota **through OpenRouter**. > - **Overflow tap:** after the standing-free hosts `429`, DeepInfra ($5) / Nebius (~$5–10) hand out one-time credit (no card), then pennies/1M tokens. _The model was never the wall — the meter was. Spread it across meters and the wall’s gone._ ---

what do you usually use agent on this kind of setup for Gemma4 31b? hermes or openclaw? ---

Thanks to all in community for helping. Cerebras will move to paid tier on 14th Aug. I got the mail from them. Google AI Studio is working and probably the best with a very generous limit. I saw @Thorgal tell about 9router. I have set it up. That helps as well. Thanks again 🙂 @niggaplsss I dont use agent (I don’t know how ☹ to use). I have prose, dense text which I need converted to bullet points. So i copy-paste chunks in playgorund using Gemma4 31B in Google AI Studio and ask it. I have give it a system prompt so every time i give it text, gemma returns in bullet points. ---

**@Vishal_Jain2** — checked independently, matches your email exactly: Cerebras killed the no-card free tier on **Aug 17, 2026**. Existing accounts move to add-a-card-for-$5-credit, then pay per token. Not a scam mail, just reality — corrected the table above ⬆. Good that Google AI Studio’s holding a generous limit and 9router’s covering the gap. **On 9router specifically — worth a 2-minute check since you’ve already got it running.** It shipped a critical bug, **CVE-2026-49352** : a hardcoded fallback JWT secret that lets anyone on the internet forge a login cookie and pull every API key sitting in its dashboard, _if_ `JWT_SECRET` was never set. Fixed in **v0.4.45+**. ```auto npm list -g 9router ``` Below 0.4.45 → `npm update -g 9router`. Or just set a real `JWT_SECRET` env var yourself — either one kills the bug. Two minutes, worth doing before more keys sit behind it. **@gman20’s [omniroute.online](https://omniroute.online/)** is the same family — literally a fork of 9router, way more providers. Independent reviews flag it harder though: API keys stored **unencrypted by default** , guardrails that **fail open** on error, and TLS-fingerprint spoofing built in specifically to dodge provider anti-abuse detection. Fine for solo tinkering behind a throwaway key, not for anything you’d mind losing. **@niggaplsss** — Hermes and OpenClaw aren’t competing _for_ Gemma specifically. Both are self-hosted personal-agent frameworks that happen to accept **any OpenAI-compatible endpoint** , so either one just points straight at the setup above ⬆. - **[Hermes Agent](https://hermes-agent.nousresearch.com/)** (Nous Research) — Python, CLI-first, self-improving skill library, 300+ models via its own Portal _or_ a custom endpoint. - **[OpenClaw](https://openclaw.ai/)** — Node/Docker, web dashboard, 30+ plugins, same custom-endpoint support. Pick by workflow — CLI + skills-that-learn vs dashboard + plugins — not by Gemma support. Both run it fine through OpenRouter/NVIDIA.
