# Model provider for AI agents Where the tokens come from. A frontier API, a gateway you control, or your own GPUs. 13 options tracked · 3 open source · 3 self-hostable · required ## All options | Option | What it does | Licence | Self-host | Page | | --- | --- | --- | --- | --- | | Anthropic | Claude Opus, Sonnet and Haiku. Strong tool use and long-horizon agentic work. | proprietary | no | https://newagent.build/c/anthropic | | OpenAI | GPT and o-series via the Responses API. | proprietary | no | https://newagent.build/c/openai | | Google Gemini | Gemini models with very long context and native multimodality. | proprietary | no | https://newagent.build/c/google-gemini | | Amazon Bedrock | Frontier models inside your AWS account, with IAM and VPC boundaries. | proprietary | no | https://newagent.build/c/bedrock | | Google Vertex AI | Claude and Gemini under GCP billing, IAM and regional controls. | proprietary | no | https://newagent.build/c/vertex | | DeepSeek | Strong reasoning and coding at a fraction of frontier pricing, with the weights published so you can move off the API later. | proprietary | no | https://newagent.build/c/deepseek | | OpenRouter | One API key, several hundred models, automatic failover. | proprietary | no | https://newagent.build/c/openrouter | | Hugging Face | One OpenAI-compatible endpoint routed across Groq, Together, Fireworks, Cerebras and Replicate — with the open-weight catalogue behind it. | proprietary | no | https://newagent.build/c/huggingface | | Venice AI | Hosted open-weight inference with no prompt logging or retention, plus an anonymising proxy in front of the frontier APIs. | proprietary | no | https://newagent.build/c/venice | | LiteLLM | Self-hosted proxy that speaks one API to 100+ providers, with keys and budgets. | open source | yes | https://newagent.build/c/litellm | | Groq | Open-weight models at very low latency. | proprietary | no | https://newagent.build/c/groq | | Ollama | Open-weight models on your own machine. Nothing leaves the box. | open source | yes | https://newagent.build/c/ollama | | vLLM | High-throughput open-weight serving on your own GPUs. | open source | yes | https://newagent.build/c/vllm | ## Benchmark: SWE-bench Verified Share of real, human-validated GitHub issues resolved end to end. - Anthropic: 96% — leaderboard, SWE-bench Verified leaderboard, 2026-08-18. https://benchlm.ai/benchmarks/sweVerified - DeepSeek: 96.4% — leaderboard, SWE-bench Verified leaderboard, 2026-08-18. https://benchlm.ai/benchmarks/sweVerified > Scores attach to a specific model, not to a provider — the model measured is named in each cell. Frontier results now cluster inside a single point and different leaderboards report different figures for the same model, so treat anything under ~1 point as noise rather than a ranking. ## Machine interfaces - `GET https://newagent.build/api/registry` — every component as JSON - `GET https://newagent.build/api/vendors` — vendors, with the repo and releases feed to watch - `GET https://newagent.build/api/advise?q=` — recommended stack for a description - `GET https://newagent.build/api/stack?=&format=sh|json|md|yml|agents|env` — a stack as files - `GET https://newagent.build/llms.txt` — the whole registry in one fetch Any page here also returns markdown if you send `Accept: text/markdown`.
