Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.

Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.

SpecialistGeneral-purpose conversational AI that can explain complex concepts and make practice quizzes, but lacks dedicated study note repositories.


Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.

Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.
Gamified flashcard and quiz creation from PDFs, but lacks Studocu's extensive crowdsourced student note library.

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.
Free / Open-sourceStronger free flashcard creation and practice tests from notes, but less reliance on crowdsourced university document sharing.

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.
SpecialistTailored for specific exam prep and coursework feedback with an AI tutor, rather than open note sharing.

Excellent AI-driven video explainers and interactive study sets, but lacks Studocu's massive repository of crowdsourced course notes.

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.
Converts multi-format lecture materials into audio podcasts and quizzes, but has a smaller community note repository.
