API Updates

Effective July 7, 2026, 00:00 (UTC), to continue providing stable and reliable service, we are updating the pricing for two image generation models:

• Seedream 4.5 — 2.375 credits per image (≈ $0.0349)
• Seedream 4.0 — 1.8 credits per image (≈ $0.0265)

Notes

• Billed per generated image; batch requests are charged as the unit price × n.
• The new pricing takes effect automatically at the time above. Requests made before then are billed at current rates.
• All other models are unaffected.

If you have any questions, please contact our support team.

Effective June 29, 2026, to continue providing stable and reliable service, we are updating the pricing for Doubao Seed Audio 1.0:

Notes

• Billed by audio duration (per second of generated audio).
• All other models and capabilities remain unchanged.

If you have any questions, please contact our support team.

We are excited to announce the launch of GLM-5.2, Z.ai's latest flagship model, now available on EvoLink.

GLM-5.2

• Model ID: glm-5.2
• Context Window: ~1M tokens, billed at a single flat rate with no long-context surcharge
• Features: Deep thinking (thinking), tool calling / function calling, prompt caching (cache reads)
• Endpoint: OpenAI-compatible /v1/chat/completions

Key Use Cases

• Coding Agents: Connect coding agents, coding CLIs, and editor tools through the OpenAI-compatible endpoint, plus repo Q&A, code generation, and review workflows
• Agentic Tool Use & Function Calling: Plan, call tools, and recover from errors across multi-step agentic workflows
• Long Context: Full codebase analysis and large-document reasoning with ~1M context
• GLM-5.2 API

Due to an upstream access-policy change on Anthropic's side, Claude Fable 5 (claude-fable-5) is temporarily unavailable. We're actively working to restore it and will share a recovery timeline as soon as we have one.

In the meantime

• Alternative: switch to Claude Opus 4.8 — also 1M context, with the same API surface as Fable 5, so migration is just a model-ID swap
• Scope: only claude-fable-5 is affected; the rest of the Claude line (Opus / Sonnet / Haiku) remains fully available
• Updates: we'll post the recovery notice here in the ChangeLog as soon as it's back

We apologize for the inconvenience.

Claude Fable 5 from Anthropic is now live on EvoLink — Anthropic's most powerful and most intelligent model, a new tier above Opus, built for the hardest coding, long-horizon agent, and high-stakes long-context work, with a 1M-token context window.

Claude Fable 5

• Model ID: claude-fable-5
• Context window: 1M tokens
• Max output: 128K tokens
• Capabilities: state-of-the-art reasoning, advanced coding, long-horizon agentic tool orchestration, vision input
• Recommended workloads: the hardest coding tasks, longest agent runs, and highest-stakes long-context decisions where stronger reasoning is worth a premium
• Pricing: $10 / 1M input, $50 / 1M output — about 2× Opus 4.8; web search tool billed per request
• API: same surface as Opus 4.8 — adaptive thinking only (no temperature / top_p / budget_tokens), effort up to max; do not send thinking: disabled (omit the parameter instead)
• Routing: keep Opus 4.8 as the strong default and escalate only frontier-difficulty requests to Fable 5
• Try Claude Fable 5

Due to cost adjustments, pricing for Veo 3.1 Fast (veo3.1-fast-beta) and Veo 3.1 Pro (veo3.1-pro-beta) has been increased, effective immediately.

See the Veo 3.1 Fast and Veo 3.1 Pro pages for current pricing.

In addition, the 1080p and 4K resolution options for these two models have been retired — only 720p is now available.

We are excited to announce the launch of MiniMax-M3, MiniMax's latest multimodal model, now available on EvoLink.

• Features: Deep thinking (thinking), multimodal input (image / video / PDF), prompt caching
• Dual Endpoints: OpenAI-compatible /v1/chat/completions + native Anthropic Messages /v1/messages (for Claude Code–style CLIs)

Key Use Cases

• Coding Agents & Claude Code: Native /v1/messages endpoint for Claude Code–style CLIs, plus repo Q&A, code generation, and review workflows
• Multimodal: Image, video, and PDF input for visual reasoning and document understanding
• Long Context: Full codebase analysis and large-document reasoning with ~1M context
