LLM costs can escalate quickly, particularly for teams running agentic systems, retrieval pipelines, or multi-turn chat with extensive context windows. Most platforms bill by the token, meaning every additional sentence in your system prompt, every retrieved document, and every reasoning step directly inflates your bill. Cost optimization therefore requires both algorithmic discipline and a pricing structure that aligns with your actual usage patterns.
Understand Pricing Structure: Token-Based vs. Request-Based
The majority of inference providers bill per token. Input tokens, output tokens, and sometimes context caching fees all accumulate. For long-context workloads or agent loops that append tool outputs back into the prompt, token counts compound rapidly. Oxlo.ai uses a request-based pricing model: one flat cost per API request regardless of prompt length. If your application sends large system prompts, few-shot examples, or lengthy retrieved documents, that workload is often significantly cheaper on a per-request platform. See the exact tiers at https://oxlo.ai/pricing.
Optimize Prompts for Latency and Accuracy
Even when cost is decoupled from token count, concise prompts reduce time-to-first-token and improve model focus. Remove redundant instructions, collapse repeated examples, and order your context so the most relevant information sits near the end of the prompt for models that use positional attention biases. On Oxlo.ai, you do not need to truncate valuable context to save money, but you should still engineer for speed and precision.
Context Management without Cost Penalties
On token-based providers, teams aggressively summarize conversation history or prune RAG results to stay under budget. With Oxlo.ai, the full context window is available at a flat per-request rate. You can pass complete conversation threads, large codebases, or extensive documentation without watching a meter run. This changes the optimization target from token minimization to information density. Keep what is useful, discard what is noisy, and stop worrying about the bill scaling with every paragraph.
Route Requests to the Right Model
Not every task requires a 70B+ parameter model. Use smaller, faster models for classification, extraction, or routing, and reserve large reasoning models for complex coding or multi-step planning. Oxlo.ai hosts over 45 models across seven categories, from Qwen 3 32B for multilingual agent workflows to DeepSeek R1 671B MoE for deep reasoning. Because the platform is fully OpenAI SDK compatible, switching models is a single parameter change.

client = OpenAI(

# Fast, inexpensive routing decision with a compact model
routing = client.chat.completions.create(

max_tokens=50
)
# Heavy reasoning only when needed
if "refund" in routing.choices[0].message.content.lower():
response = client.chat.completions.create(

messages=[{"role": "user", "content": "Draft a detailed refund policy analysis."}],

)
for chunk in response:
print(chunk.choices[0].delta.content or "", end="")
Use Structured Outputs and Streaming to Reduce Iterations
Every extra request costs time and money. Use JSON mode and function calling to get exactly what you need in a single round trip, eliminating the need to re-prompt for parsing or validation. Oxlo.ai supports
