6 models, one API key
Access DeepSeek V4, Nemotron 3, Llama, Mistral, GPT-OSS, FLUX and more frontier models through one OpenAI-compatible API key — every model priced per token, no subscriptions. Every model below is health-checked continuously, so the catalog only lists what is actually running. Filter by capability, copy the model id, and start calling Speka in minutes.
What models can I call on Speka?
Speka is a unified AI model API that provides developer access to 6 frontier open-weight models — including DeepSeek V4, Nemotron 3 Ultra 550B, Mistral Nemotron, GPT-OSS and FLUX.1 for image generation — through a single OpenAI-compatible endpoint. Pricing is transparent and per-token, with no subscriptions or seat fees. Input prices run from $0.01 per million tokens for embeddings to $0.90 per million tokens for Nemotron 3 Ultra 550B. Developers switch between models by changing one parameter — the model field — with no SDK changes required. Model weights and benchmarks for these open models are published by their labs — for example DeepSeek and Black Forest Labs (FLUX) on Hugging Face.
GPT-OSS 20B
The small GPT-OSS tier — quick code completion, refactors and shell/tool calls at a fraction of the price.
