Together AI Cost Tuning

Overview

Optimize Together AI costs with model selection, batching, and caching.

Together AI Pricing Model

Model Category Price (per 1M tokens) Example Models
Small (< 10B) $0.10-0.30 Llama-3.2-3B, Qwen-2.5-7B
Medium (10-40B) $0.60-1.20 Mixtral-8x7B, Llama-3.3-70B-Turbo
Large (40B+) $2.00-5.00 Llama-3.1-405B, DeepSeek-V3
Image gen $0.003-0.05/image FLUX.1-schnell, SDXL
Embeddings $0.008/1M tokens M2-BERT
Fine-tuning ~$5-25/hour Depends on model + GPU
Batch inference 50% off Same models, async

Cost Reduction Strategies

# 1. Use Turbo variants (faster, cheaper, similar quality)
# meta-llama/Llama-3.3-70B-Instruct-Turbo vs Llama-3.1-70B-Instruct

# 2. Batch inference (50% cost reduction)
batch_response = client.batch.create(
    input_file_id=file_id,
    model="meta-llama/Llama-3.3-70B-Instruct-Turbo",
    completion_window="24h",
)

# 3. Cache responses for identical prompts
from functools import lru_cache

@lru_cache(maxsize=1000)
def cached_completion(prompt: str, model: str) -> str:
    response = client.chat.completions.create(
        model=model, messages=[{"role": "user", "content": prompt}],
    )
    return response.choices[0].message.content

# 4. Use smallest model that works
# Test with 3B first, upgrade to 70B only if quality insufficient

Error Handling

Issue Cause Solution
High costs Wrong model tier Downsize model
Batch failures Invalid input format Validate JSONL
Fine-tuning expensive Too many epochs Start with 1-2 epochs
