Defained vs Together AI

SpecialistProvides industry-leading proprietary frontier models and enterprise reliability, but completely lacks support for open-weight community models.

SpecialistRestricts API usage strictly to Gemini models, offering free prototyping tiers but lacking open-source model variety.

Aggregates hundreds of models through a single API, offering broader model choice than Together AI's hosted lineup.

Delivers dramatically faster token generation speeds using custom hardware, though with a more limited model selection.

SpecialistOne API for 1,500+ production-ready generative media models

Focuses heavily on deploying custom machine learning models and media generation pipelines alongside standard text LLMs.

Free / Open-sourceOpen-source, memory-efficient fine-tuning and local model running

A prompt library and management layer for ChatGPT and other AI models

Provides exceptionally fast inference speeds and robust fine-tuning tools, competing directly on open-source model deployment performance.

Offers similar low-cost serverless inference for open-weight models, but with a simpler pay-as-you-go pricing model.
