8 Best Martian LLM Router Alternatives in 20262026 年 8 个最佳 Martian LLM 路由器替代方案
Compare Martian alternatives by the job you actually need: quality-aware model selection, multi-provider access, self-hosting, governance, observability, cost control, or migration simplicity.
按照真正需要完成的任务比较 Martian 替代方案：质量感知模型选择、多供应商接入、自托管、治理、可观测性、成本控制或低风险迁移。
TL;DR
Martian currently presents Model Router and Gateway capabilities, provider metrics, and integrations for agent coding tools. Do not base a migration on the old inactive-page assumption.
For managed, quality-aware model selection, Not Diamond is the most direct functional comparison. RouteLLM is the stronger open implementation starting point.
OpenRouter, Portkey, Requesty, Vercel AI Gateway, LiteLLM, and Bifrost emphasize access, policy, fallback, or operations to different degrees.
Test task success, cost at fixed quality, latency, fallback behavior, data controls, and operator effort before moving production traffic.
Martian 当前仍提供 Model Router、Gateway、供应商指标以及面向智能体编程工具的集成。不要再依据“旧页面失效”的错误前提决定迁移。
如果需要托管式、质量感知模型选择，Not Diamond 是最直接的功能对比；RouteLLM 更适合作为开源实现起点。
OpenRouter、Portkey、Requesty、Vercel AI Gateway、LiteLLM 和 Bifrost 分别侧重接入、策略、回退或运营能力。
迁移生产流量前，应测试任务成功率、固定质量下的成本、延迟、回退行为、数据控制和运维投入。
Start with Martian's current routing baseline先明确 Martian 当前的路由基线
Martian's current official materials describe a Model Router that chooses models by prompt, plus a Gateway that provides access to more than 200 models through one API key. Its provider leaderboard tracks cost, rate limits, throughput, and time to first token, while official integrations cover Cursor, Cline, Windsurf, and related agent workflows. A real alternative must replace the specific parts you use—not merely offer an OpenAI-compatible base URL.
Martian 当前官方资料明确介绍了按提示词选择模型的 Model Router，以及通过一个 API Key 接入 200 多个模型的 Gateway。供应商排行榜跟踪成本、速率限制、吞吐量和首 Token 延迟，官方集成覆盖 Cursor、Cline、Windsurf 等智能体工作流。真正的替代方案必须替换你实际使用的具体能力，而不只是提供兼容 OpenAI 的基础地址。
Define the replacement boundary. Record whether you need predictive model selection, provider failover, one billing account, self-hosting, data residency, prompt logging, or all of them.
先定义替代边界。明确你需要的是预测式模型选择、供应商故障转移、统一账单、自托管、数据驻留、提示词日志，还是全部能力。
Match the Martian alternative to the actual job让 Martian 替代方案匹配实际任务
Choose Not Diamond for a managed pre-trained or custom router; choose RouteLLM when you want to operate and evaluate an open routing implementation yourself.
Choose OpenRouter or Requesty when one API, broad model access, fallback, and faster onboarding matter more than custom predictive routing.
Choose Portkey or Vercel AI Gateway when policy, observability, budgets, application integration, and managed operations dominate the decision.
Choose LiteLLM or Bifrost when your team can own deployment, credentials, upgrades, telemetry, failure recovery, and routing rules.
需要托管的预训练或自定义路由器时选择 Not Diamond；希望自行运行和评估开源路由实现时选择 RouteLLM。
当统一 API、广泛模型接入、回退和快速上线比自定义预测路由更重要时，选择 OpenRouter 或 Requesty。
当策略、可观测性、预算、应用集成和托管运营是核心时，选择 Portkey 或 Vercel AI Gateway。
当团队能够承担部署、凭证、升级、遥测、故障恢复和路由规则时，选择 LiteLLM 或 Bifrost。

How to benchmark a Martian alternative如何评测 Martian 替代方案
Build a hidden evaluation set from real prompts and split it by task, tenant, risk, and time. Enforce hard constraints first—region, model allowlist, modality, context size, tool support, privacy, and maximum latency—then compare task success, cost, time to first token, total latency, routing stability, and fallback behavior. Always include three simple baselines: one strong model, one cheap model, and deterministic rules.
从真实提示词建立隐藏评估集，并按任务、租户、风险和时间切分。先执行区域、模型白名单、模态、上下文长度、工具支持、隐私和最大延迟等硬约束，再比较任务成功率、成本、首 Token 延迟、总延迟、路由稳定性和回退行为。始终加入三个简单基线：固定强模型、固定低价模型和确定性规则。
- Report quality at a fixed cost and cost at a fixed quality; a blended score can hide an unacceptable trade-off.
- Test provider outages, rate limits, malformed streaming responses, long contexts, tool calls, and structured-output failures.
- Measure operator work: deployment, model onboarding, key rotation, audit export, policy changes, and incident recovery.
- Re-run after model releases, price changes, routing-policy updates, or meaningful shifts in prompt distribution.
- 分别报告固定成本下的质量和固定质量下的成本；混合分数可能掩盖不可接受的取舍。
- 测试供应商故障、限流、异常流式响应、长上下文、工具调用和结构化输出失败。
- 衡量运维工作：部署、模型接入、密钥轮换、审计导出、策略修改与事故恢复。
- 模型发布、价格变化、路由策略更新或提示词分布明显变化后重新测试。
Migrate the decision policy, not just the endpoint迁移决策策略，而不只是端点
Inventory Martian model aliases, provider preferences, quality thresholds, cost weights, latency ceilings, fallbacks, tenant policies, evaluation datasets, graders, and decision logs. Map each item to the candidate, replay historical traffic offline, and compare both routing decisions and final answers. Then shadow live traffic, canary a bounded tenant or percentage, define rollback thresholds, and keep Martian available until quality, cost, streaming, tool calls, and gateway reliability reconcile.
盘点 Martian 的模型别名、供应商偏好、质量阈值、成本权重、延迟上限、回退、租户策略、评估集、评分器和决策日志。逐项映射到候选方案，离线重放历史流量，同时比较路由决策和最终答案。随后影子运行实时流量，对有限租户或比例进行 Canary，定义回滚阈值，并在质量、成本、流式输出、工具调用和网关可靠性全部核对前保留 Martian。
Model routing and capability routing solve different jobs模型路由与能力路由解决不同任务
Martian and the eight alternatives on this page decide which LLM or provider should handle inference. QVeris operates after or alongside that decision: it helps an agent discover, inspect, and call external APIs, data sources, and tools. QVeris is therefore not a Martian replacement. A complete agent stack can use an LLM router for inference and QVeris for downstream capability execution, joined by one trace ID for cost, evidence, and incident review.
Martian 与本文八个替代方案决定由哪个 LLM 或供应商处理推理；QVeris 在该决策之后或旁路工作，帮助智能体发现、检查并调用外部 API、数据源和工具。因此，QVeris 不是 Martian 的直接替代品。完整智能体技术栈可以用 LLM 路由器处理推理，用 QVeris 执行下游能力，并通过同一个调用链 ID 关联成本、证据和事故复盘。
FAQ
Not Diamond is the closest managed option for quality-aware model selection. RouteLLM is the strongest open starting point, while gateways such as Portkey, OpenRouter, Requesty, and LiteLLM fit different operational requirements.
Yes. Martian's current site and documentation describe Model Router and Gateway products, a provider leaderboard, and integrations for Cursor, Cline, Windsurf, and other agent tools.
Only if deterministic rules, provider fallback, or manual model selection are sufficient. A gateway does not automatically predict which model will produce the best answer for each prompt.
Yes. LiteLLM and Bifrost provide self-hosted gateway paths, while RouteLLM provides an open model-routing framework. Your team must own reliability, security, upgrades, evaluation, and incident response.
质量感知模型选择方面，Not Diamond 是最接近的托管方案；RouteLLM 是较强的开源起点。Portkey、OpenRouter、Requesty 和 LiteLLM 等网关则适合不同运营要求。
可用。Martian 当前官网和文档仍介绍 Model Router、Gateway、供应商排行榜，以及面向 Cursor、Cline、Windsurf 等智能体工具的集成。
只有在确定性规则、供应商回退或手动选模型足够时才可以。普通网关不会自动预测每个提示词由哪个模型生成最佳答案。
可以。LiteLLM 和 Bifrost 提供自托管网关路径，RouteLLM 提供开放模型路由框架；团队需要自行承担可靠性、安全、升级、评估和事故响应。
