No, Fireworks hosts the unaltered versions of DeepSeek models.

• ❌ No quantization – Full-precision versions are hosted.
• ❌ No additional censorship – Fireworks does not apply additional content moderation beyond DeepSeek’s built-in policies.
• ❌ No forced system prompt – Users have full control over prompts.

🔹 Fireworks hosts DeepSeek R1 and V3 models on Serverless. Contact us at inquiries@fireworks.ai if you need a dedicated deployment.

🔹 Fireworks also offers six R1-distill models released by DeepSeek on on-demand.

Fireworks has zero-data retention by default and does not log or store prompt or generation data.

See Fireworks Data Handling Policy for details.

The company DeepSeek does not have access to user API requests or outputs.

Fireworks hosts DeepSeek models on our own infrastructure. We do not proxy requests to DeepSeek API.

We are continuously optimizing the model for speed and throughput. We also offer useful developer features like JSON mode, structured outputs, and dedicated deployment options.

Yes, Fireworks offers dedicated deployments for DeepSeek models.
Contact us at inquiries@fireworks.ai if you need a dedicated deployment.

• 🚀 Lower latency – Dedicated instances have better response times than shared serverless.
• 📈 Higher throughput – More consistent performance for large-scale applications.
• 💰 Pricing: Depends on workload, contact us at inquiries@fireworks.ai.

Yes! Fireworks supports structured outputs through:

• ✔️ JSON Mode – Enforce JSON responses for structured applications.
• ✔️ Grammar Mode – Define syntactic constraints for predictable outputs.

Currently, DeepSeek R1 does not support native function calling like OpenAI models.
However:

• Users can implement function calling logic via prompt engineering or structured output parsing.
• Fireworks is evaluating future support for function calling in DeepSeek models.

Max token length for DeepSeek models is only limited by the context window of the model, which is 128K tokens.

If responses are cut off, try increasing max_tokens in your API call:
🔗 Fireworks Max Tokens Documentation

DeepSeek R1 uses <think> tags to denote reasoning before the final structured output.

Fireworks defaults to the simplest approach of returning <think>...</think> in the response and letting the user parse the response, such as using regex parsing.

Fireworks updates DeepSeek R1 and v3 in alignment with DeepSeek AI’s official releases and Fireworks’ own performance optimizations.

Updates include bug fixes, efficiency improvements, and potential model refinements.

Users can track updates through Fireworks documentation and announcements.

If you’re encountering an error while using DeepSeek v3 on Fireworks, follow these steps:

✅ Step 1: Check Fireworks’ Status Page for any ongoing outages.

✅ Step 2: Verify API request formatting. Ensure:

• No missing/invalid API keys
• Proper request format
• No exceeded rate limits or context window

✅ Step 3: Reduce request complexity if your request is too long.

✅ Step 4: Adjust parameters if experiencing instability:

• Lower temperature for more deterministic responses
• Adjust top_p to control randomness
• Increase max_tokens to avoid truncation

✅ Step 5: Contact Fireworks support via:

• 🔗 Fireworks Support
• 🔗 Fireworks Discord for real-time help.

DeepSeek v3 and R1, like other LLMs, have a fixed maximum context length of 128K tokens.
If responses are getting cut off:

🔹 Possible Causes & Solutions:

1️⃣ Exceeded max_tokens setting → 🔧 Increase max_tokens

2️⃣ Requesting too much text in a single prompt → 🔧 Break input into smaller chunks

3️⃣ Model context window limit reached → 🔧 Summarize prior messages before appending new ones

💡 Fix:

response = client.chat.completions.create(
    model="accounts/fireworks/models/deepseek-v3",
    messages=[{"role": "user", "content": "Generate a long article summary"}],
    max_tokens=4096,  # Adjust as needed
)

📌 Alternative Fix: If you need longer responses, re-prompt the model with the last part of the output and ask it to continue.

Intermittent API response issues could be due to:
🔹 Common Causes & Fixes:

1️⃣ High Server Load – Fireworks may be experiencing peak traffic.
Fix: Retry the request after a few seconds or try during non-peak hours.

2️⃣ Rate Limits or Spend Limits Reached – If you’ve exceeded the API rate limits, requests may temporarily fail.
Fix: Check your rate limits and spend limits in the API dashboard and adjust your usage accordingly.
🔗 To increase spend limits, add credits: Fireworks Spend Limits

3️⃣ Network Connectivity Issues – Fireworks API may be unreachable due to network issues.
Fix: Restart your internet connection or use a different network/VPN.
