Introduction
Slicing "free LLM APIs" by capability makes the landscape far easier to navigate. Instead of memorizing dozens of model names, you can reason about three task families — text, image, and voice — and slot any new model into the right family as it appears. This article picks representative endpoints from each family, lists quotas and use cases, and gives a unified code pattern so you can swap providers without rewriting application logic.
Text and Chat
- OpenRouter:
openrouter.ai/api/v1—:freemodels cost nothing, fully OpenAI-SDK compatible. - Groq:
api.groq.com/openai/v1— LPU inference brings time-to-first-token into the tens of milliseconds. - DeepSeek:
api.deepseek.com/v1—deepseek-reasonerreasoning path excels at math and code. - Gemini:
generativelanguage.googleapis.com/v1beta— multimodal input, 1M context in the free tier. - Mistral:
api.mistral.ai/v1—open-mistral-7band Mixtral 8x7B both have free quotas.
Image Generation
- Hugging Face Inference: call
black-forest-labs/FLUX.1-dev,stabilityai/sdxl, and other open-weight image models directly. Free tier starts at 1 RPM. - Pollinations.ai:
https://image.pollinations.ai/prompt/{prompt}— a URL is enough to get an image, no sign-up needed. Ideal for demos and placeholder art. - Together AI: FLUX schnell runs hundreds of images inside the $5 credit, endpoint
api.together.xyz/v1/images/generations.
Voice
- ASR (speech-to-text):
whisper-large-v3via Hugging Face or Groq. The Groq endpoint transcribes a minute of audio in seconds. - TTS (text-to-speech): Edge-TTS is fully free (built on Microsoft Edge online TTS). Coqui XTTS, self-hosted, can clone voices. Fish Audio has a trial quota.
Unified Code Pattern
from openai import OpenAI
# Text chat: OpenRouter calling Llama 3.3 70B free
client = OpenAI(base_url="https://openrouter.ai/api/v1", api_key="sk-or-...")
r1 = client.chat.completions.create(
model="meta-llama/llama-3.3-70b-instruct:free",
messages=[{"role": "user", "content": "Explain vector databases in 100 words."}],
)
# Image: Pollinations URL API (no key needed)
import requests
url = "https://image.pollinations.ai/prompt/" + requests.utils.quote("cyberpunk city at night")
img = requests.get(url, timeout=120).content
# ASR: Groq Whisper
gclient = OpenAI(base_url="https://api.groq.com/openai/v1", api_key="gsk_...")
with open("audio.mp3", "rb") as f:
r3 = gclient.audio.transcriptions.create(model="whisper-large-v3", file=f)
print(r3.text)
Selection Guidance
For text chat, run OpenRouter (widest coverage) plus Groq (lowest latency) as dual backups. For image generation, use Hugging Face as the controllable path and Pollinations as the no-key fallback. For voice, start with Groq Whisper for ASR and Edge-TTS for TTS; switch to self-hosted Coqui when you need voice cloning. With one fallback per family, no single provider outage can take the product down.
