Sourcegraph 6.5

A newer version of Sourcegraph is available: Sourcegraph 6.12.

This page includes all changes for 6.5 and its patch releases. The latest patch for 6.5 is 6.5.2654.

Highlights

OAuth 2.0 support for secure API access

Enterprise customers can now use OAuth 2.0 to securely connect apps and scripts to Sourcegraph APIs with support for OIDC, PKCE, device auth, and M2M tokens.

Enterprise customers can now use OAuth 2.0 to securely connect apps and scripts to Sourcegraph APIs, just like you would with GitHub or GitLab. This includes full support for OIDC, PKCE, device auth, and M2M tokens.

With short-lived access tokens, your tools can act on behalf of users, making it easier to build custom automations and workflows on top of Sourcegraph. If you’ve been blocked from integrating because auth was missing or hard to manage, this clears the path.

Admins can create OAuth clients under Site admin > OAuth clients and use them to integrate with Sourcegraph via standard OAuth procedures.

Service accounts for secure API integrations

Service accounts let admins create non-UI actors with API access - ideal for secure, controlled integrations.

We’ve introduced service sccounts, a new way for administrators to create Sourcegraph actors that are designed specifically for API access without UI access or user credentials.

Create user form with service account option

Service accounts are useful in a number of ways:

No email or password required
Managed by admins
Accessed via token
No UI login capability

This gives enterprise teams a more secure and standardized way to integrate with Sourcegraph, perfect for automated workflows or custom tooling that interacts with our API.

While adoption is optional, customers building API-driven integrations will benefit from stronger access control, better auditability, and alignment with a supported integration pattern.

Expanded context windows for Cody Chat

We've increased input and output context limits across models to support more powerful, large-scale coding workflows.

Developers increasingly want to work with more context, whether it's reviewing all files in a pull request, generating a new Dockerfile based on all others in a repo, or reasoning across a large set of project resources. But context limits have traditionally capped how much they can reference in a single request, leading to fragmented workflows or lower quality responses.

To help with this, we're expanding both input and output context windows in Cody Chat for Cody Enterprise customers.

Input context window (via @mention):

Claude & Gemini: ~115k tokens
OpenAI o-series: ~43k tokens
OpenAI GPT-series: ~52k tokens

Output context window:

All models: 16k
Reasoning models: 100k

Other

Completions: add special cody_debug:::{} prompt syntax site admins can use to measure latency
test: added special debug syntax usable by site admins to measure completions latency.
Bedrock: do not discard IAM machine-credential authentication cache; add support for latency optimized inference
- bedrock: added support for AWS Bedrock Latency Optimized Inference which can reduce autocomplete latency with e.g. Haiku 3.5 models by as much as 40%.
- bedrock: fixed an issue where Cody's AWS Bedrock implementation would incorrectly discard the IAM machine-credential cache, making static access tokens potentially faster in older versions.
