Arize Phoenix vs LiteLLM: at a glance
What is Arize Phoenix?
Phoenix evals pins out a compromised LiteLLM release and the emSign root.
Arize Phoenix is shipping near-daily releases across its server, Python evals and TypeScript packages. The past week was mostly fixes and dependency hygiene: evals 3.9.3 excluded the compromised LiteLLM 1.107.0 and required a certifi build that distrusts the emSign root, and later patches refreshed playground presets and evals kwargs handling. Server 20.25 and 20.26 mainly carried the team's internal issue-to-PR agent tooling, plus a service.version attribute on Phoenix's own OpenTelemetry resource.
What is LiteLLM?
LiteLLM's 1.109 dev build stacks 704 PRs and 15 required config changes.
LiteLLM is patching four stable lines (1.103 to 1.106) in lockstep, most recently with leaner failure logs, a proxy-level GCS logger config and a new cosign signing key. On Oct 28 it opened a 1.109.0 dev line with 704 merged PRs and 15 items flagged as action required. Those include a new image-verification key, Gemini 3.6 Flash rejecting temperature/top_p/top_k, no more local token-count estimates, and budget edits on keys restricted to admins.

Arize Phoenix
5.0AI-ML-PLATFORMS
Phoenix evals pins out a compromised LiteLLM release and the emSign root.
◆ Current state
Arize Phoenix is shipping near-daily releases across its server, Python evals and TypeScript packages. The past week was mostly fixes and dependency hygiene: evals 3.9.3 excluded the compromised LiteLLM 1.107.0 and required a certifi build that distrusts the emSign root, and later patches refreshed playground presets and evals kwargs handling. Server 20.25 and 20.26 mainly carried the team's internal issue-to-PR agent tooling, plus a service.version attribute on Phoenix's own OpenTelemetry resource.
◆ Where it's heading
Phoenix keeps widening tracing coverage through integration pages (Pipecat, Microsoft Agent Framework) and its TypeScript evals, which now run classifiers on AI SDK decision models. The core product sees small, frequent fixes rather than large features right now, and supply-chain pinning has become part of the release routine.
◆ Prediction
The TypeScript decision-model support is pinned to experimental AI SDK versions, so expect follow-up patches as that API changes.
LiteLLM
5.0AI-ML-PLATFORMS
LiteLLM's 1.109 dev build stacks 704 PRs and 15 required config changes.
◆ Current state
LiteLLM is patching four stable lines (1.103 to 1.106) in lockstep, most recently with leaner failure logs, a proxy-level GCS logger config and a new cosign signing key. On Oct 28 it opened a 1.109.0 dev line with 704 merged PRs and 15 items flagged as action required. Those include a new image-verification key, Gemini 3.6 Flash rejecting temperature/top_p/top_k, no more local token-count estimates, and budget edits on keys restricted to admins.
◆ Where it's heading
The stable lines get hardening and backports, while the next minor is moving the gateway toward stricter defaults: tighter key and budget permissions, explicit max_tokens for unmapped Anthropic models, and provider-side token counting. The size of the action-required list means upgrades are turning into real migrations for self-hosters.
◆ Prediction
Expect more 1.109 dev and rc builds that trim or document the breaking list before a stable 1.109.0, while the 1.103 to 1.106 lines keep getting matching patches.
