Together AI upgraded its fine-tuning platform, adding support for over a dozen large models (including DeepSeek, Qwen, Meta, and OpenAI's gpt-oss), extending context lengths by 2x-4x (up to 131k tokens), and integrating with Hugging Face Hub for model fine-tuning.

## Evidence

Verbatim from https://www.together.ai/blog/fine-tuning-updates-sept-2025:

> Given this trend, we wanted to make it possible for AI developers to harness long-context abilities in fine-tuning. To make this happen, we have overhauled our training systems and identified ways to increase the maximum supported context length for most of our models — at no additional cost to you. On average, you can expect 2x-4x increases to the context length, with some settings (like Llama 3.1-8B or Gemma 3-4B) jumping to their maximum length of 131k tokens.
