Our Models
Proprietary Models: Assisters develops and serves our own AI models, similar to how Anthropic serves Claude or OpenAI serves GPT. All models are optimized for performance, safety, and reliability.
Chat Completions
Generate conversational responses with streaming support. Perfect for chatbots, assistants, and interactive applications.
response = client.chat.completions.create(
model="assisters-chat-v1",
messages=[{"role": "user", "content": "Explain quantum computing"}],
stream=True
)Vision Analysis
Analyze images, extract text (OCR), and answer visual questions.
response = client.chat.completions.create(
model="assisters-vision-v1",
messages=[{
"role": "user",
"content": [
{"type": "text", "text": "What's in this image?"},
{"type": "image_url", "image_url": {"url": "https://..."}}
]
}]
)Code Generation
Expert code generation, debugging, and technical documentation.
response = client.chat.completions.create(
model="assisters-code-v1",
messages=[{"role": "user", "content": "Write a Python function to sort a list"}]
)Text Embeddings
Create vector representations for semantic search, clustering, and similarity matching.
response = client.embeddings.create(
model="assisters-embed-v1",
input="Your text here"
)Content Moderation
Detect harmful, inappropriate, or policy-violating content before it reaches your users.
response = client.moderations.create(
model="assisters-moderation-v1",
input="Content to check"
)Document Reranking
Improve search results by reranking documents based on relevance to a query.
response = requests.post(
"https://api.assisters.dev/v1/rerank",
json={
"model": "assisters-rerank-v1",
"query": "search query",
"documents": ["doc1", "doc2", "doc3"]
}
)Speech-to-Text
Transcribe audio in 100+ languages with high accuracy.
response = client.audio.transcriptions.create(
model="assisters-whisper-v1",
file=audio_file
)Text-to-Speech
Generate natural speech with 300+ voices in 100+ languages.
response = client.audio.speech.create(
model="assisters-tts-v1",
input="Hello, welcome to Assisters!",
voice="alloy"
)Image Generation
Create high-quality images from text descriptions.
response = client.images.generate(
model="assisters-image-v1",
prompt="A futuristic city at sunset"
