Pipeshift AI recently launched!

Launch YC: Pipeshift AI - Fine-tuning and inference for open-source LLMs
"Replace GPT/Claude in production with specialized LLMs that are fine-tuned on your context, offering higher accuracy, lower latencies and model ownership."

TL;DR: Pipeshift is the cloud platform for finetuning and inferencing open-source LLMs, helping teams get to production with their LLMs faster than ever. With Pipeshift, companies making >1000 calls/day on frontier LLMs can use their data and logs to replace GPT/Claude with specialized LLMs that offer higher accuracy, lower latencies, and model ownership. Connect with the founders.

🧨 The Problem: Building with Open-source LLMs is hard!

The open-source AI stack is missing, forcing most teams to experiment by duct-taping things like TGI/vLLM but having nothing ready for production. As you scale, it requires expensive ML talent, long build cycles, and constant optimizations.

The gap between open-source and closed-source models is shrinking (Meta's Llama 3.1 405B is a testament to that)! And open-source LLMs offer multiple benefits over their closed-source counterparts:

🔏 Model ownership and IP control

🎯 Verticalization and customizability

🏎️ Improved inference speeds and latency

💰 Reduction of API costs at scale


🎉 The Solution: Heroku/Vercel for Open-source LLMs

Pipeshift is the cloud platform for fine-tuning and inferencing open-source LLMs, helping developers get to production with their LLMs faster than ever.

🎯 Fine-tune Specialized LLMs

Run multiple LoRA-based fine-tuning jobs to build specialized LLMs.

⚡️ Serverless APIs of Base and Fine-tuned LLMs

Run inference for your fine-tuned LLMs and pay as per your token usage.

🏎️ Dedicated Instances for High Speed and Low Latency

Use Pipeshift AI's optimized inference stack to get max throughputs and utilization on GPUs.

Pipeshift AI's inference stack is one of the best globally, hitting 150+ tokens/sec on 70B parameter LLMs without any model quantization. And, since their private beta access was opened (<2 weeks back), they have already seen 25+ LLMs being fine-tuned with over 1.8B tokens in training data across 15+ companies.
