LiteLLM now supoports videos character, edit and extension apis.

Connect to the Realtime API via WebRTC from browser/mobile clients. LiteLLM handles auth and key management.

Duration: Ongoing (until fix deployed)
Severity: High (for users load balancing Responses API across different API keys)
Status: Resolved

Summary​

When load balancing OpenAI's Responses API across deployments with different API keys (e.g., different Azure regions or OpenAI organizations), follow-up requests containing encrypted content items (like rs_... reasoning items) would fail with:

{
  "error": {
    "message": "The encrypted content for item rs_0d09d6e56879e76500699d6feee41c8197bd268aae76141f87 could not be verified. Reason: Encrypted content organization_id did not match the target organization.",
    "type": "invalid_request_error",
    "code": "invalid_encrypted_content"
  }
}

Encrypted content items are cryptographically tied to the API key's organization that created them. When the router load balanced a follow-up request to a deployment with a different API key, decryption failed.

• Responses API calls with encrypted content: Complete failure when routed to wrong deployment
• Initial requests: Unaffected — only follow-up requests containing encrypted items failed
• Other API endpoints: No impact — chat completions, embeddings, etc. functioned normally

Severity: High (for users with provider wildcard access rules)
Status: Resolved

Summary​

When a new Anthropic model (e.g. claude-sonnet-4-6) was added to the LiteLLM model cost map and a cost map reload was triggered, requests to the new model were rejected with:

key not allowed to access model. This key can only access models=['anthropic/*']. Tried to access claude-sonnet-4-6.

The reload updated litellm.model_cost correctly but never re-ran add_known_models(), so litellm.anthropic_models (the in-memory set used by the wildcard resolver) remained stale. The new model was invisible to the anthropic/* wildcard even though the cost map knew about it.

• LLM calls: All requests to newly-added Anthropic models were blocked with a 401.
• Existing models: Unaffected — only models missing from the stale provider set were impacted.
• Other providers: Same bug class existed for any provider wildcard (e.g. openai/*, gemini/*).
