v1.90.0 - Six New Providers, OpenTelemetry v2 Parity & Streaming Reliability

Deploy this version​

docker run \
-e STORE_MODEL_IN_DB=True \
-p 4000:4000 \
docker.litellm.ai/berriai/litellm:1.90.0

Key Highlights​

  • Six new providers - ModelScope, LibertAI, Parasail, Pinstripes, TinyFish (search), and FastCRW (search) - plus a new e2b code-execution sandbox primitive.
  • 91 new models across Fireworks AI, Scaleway, Tensormesh, LibertAI, Azure AI (including gpt-5.5 and DeepSeek V4), and Bedrock Mantle.
  • OpenTelemetry v2 reaches metrics parity with v1, emitting the six gen_ai.client.* metrics, stamping input/output message content, and scoping OTLP credentials per tenant.
  • A broad streaming-reliability sweep: upstream connections are now released when the client disconnects mid-stream (Gemini, aiohttp), requests are cancelled cleanly, and partial spend is recorded on interrupted streams.
  • Two new guardrails (Cisco AI Defense, Repello Argus) and a large Next.js App Router UI migration covering the models, teams, users, organizations, api-keys, and usage pages.
